Core Definition and Mathematical Foundation of Percentage Return
Percentage return measures the gain or loss of an investment relative to its initial value, expressed as a percentage. It serves as a standardized metric for evaluating performance across financial instruments, from stocks to real estate. The formula integrates algebraic principles—specifically division by the initial value and multiplication by 100—to normalize returns for comparability. This foundational approach ensures consistency in financial analysis, risk assessment, and benchmarking.
The mathematical derivation relies on two critical components: the divisor (initial value or change) and the multiplier (100%). The divisor determines whether the return is absolute (based on profit/loss) or relative (based on growth rate), while the multiplier converts the decimal result into a percentage. Below, the distinction between these approaches is clarified, alongside their practical applications in investment evaluation.
Formula Breakdown: Divisor and Multiplier in Percentage Return
The general formula for percentage return is structured as:```
Percentage Return = [(Final Value − Initial Value) / Divisor] × 100
```
The divisor can vary based on the type of return being calculated:
The multiplier (100%) standardizes the result, eliminating decimal representation and facilitating direct comparison. For example, a return of 0.25 becomes 25% when multiplied by 100.
Side-by-Side Comparison of Percentage Return Formulas
The following table contrasts key return calculations, including their formulas, example calculations, and primary use cases. Each scenario demonstrates how the divisor and multiplier interact to produce meaningful financial insights.| Scenario | Formula | Example Calculation | Key Use Case |
|---|---|---|---|
| Absolute Return (Profit/Loss) | [(Final Value − Initial Value) / Initial Value] × 100 |
Initial Investment = $1,000 Final Value = $1,200 Calculation: [(1,200 − 1,000) / 1,000] × 100 = 20% |
Assessing short-term performance of a single investment (e.g., stock trades, bond yields). |
| Relative Return (Growth Rate) | [(Final Value − Initial Value) / Reference Value] × 100 |
Initial Value = $100 Final Value = $125 Reference = Peer Benchmark ($110) Calculation: [(125 − 100) / 110] × 100 ≈ 22.73% |
Comparing portfolio performance against market indices (e.g., S&P 500) or sector averages. |
| Simple Return (Single Period) | [(Final Value − Initial Value) / Initial Value] × 100 |
Initial Price = $50 Final Price = $55 Calculation: [(55 − 50) / 50] × 100 = 10% |
Evaluating annualized returns for non-compounding instruments (e.g., savings accounts, fixed deposits). |
| Compound Return (Multi-Period) | [(Final Value / Initial Value)^(1/n) − 1] × 100Where n = number of periods. |
Initial Investment = $1,000 Final Value = $1,464.10 (after 3 years) Calculation: [(1,464.10 / 1,000)^(1/3) − 1] × 100 ≈ 15% annualized |
Measuring long-term growth of reinvested assets (e.g., mutual funds, retirement accounts). |
Deriving Percentage Return from Raw Data
To illustrate the algebraic progression from raw data to percentage return, consider the following example:Scenario: An investor purchases a stock at $100 and sells it later for $125.
1. Calculate the Change in Value:
```
Change = Final Value − Initial Value = $125 − $100 = $25
```
2. Determine the Divisor:
For absolute return, the divisor is the initial value:
```
Divisor = Initial Value = $100
```
3. Compute the Decimal Return:
```
Decimal Return = Change / Divisor = $25 / $100 = 0.25
```
4. Apply the Multiplier:
```
Percentage Return = Decimal Return × 100 = 0.25 × 100 = 25%
```
Visual Progression:
```
Initial Value ($100) → [+$25 Change] → Final Value ($125)
Divide Change by Initial ($25 / $100) → 0.25 → Multiply by 100 → 25%
```
This method ensures transparency in financial reporting and aligns with industry standards for return calculations. For compound returns, the process extends to iterative periods, incorporating intermediate gains or losses into the divisor at each stage.
Handling Edge Cases in Percentage Return Calculations
Certain scenarios require adjustments to the standard formula to avoid misinterpretation or errors. These include:- Zero or Negative Initial Values:
Absolute returns cannot be calculated if the initial value is zero (division by zero). Relative returns may require alternative benchmarks (e.g., industry averages).
- Negative Returns (Losses):
The formula remains identical, but the result is negative (e.g., a final value of $75 from an initial $100 yields −25%). This indicates a loss rather than a gain.
- Fractional or Decimal Values:
Precision is maintained by carrying intermediate calculations to sufficient decimal places (e.g., 3–4 decimal points) before rounding the final percentage.
Example of Negative Return:
```
Initial Value = $200
Final Value = $150
Calculation: [(150 − 200) / 200] × 100 = −25%
```
Example of Fractional Precision:
```
Initial Value = $1,000
Final Value = $1,050.75
Calculation: [(1,050.75 − 1,000) / 1,000] × 100 = 5.075% (rounded to 5.08%)
The following table outlines the structured approach, including adjustments for inflation, fees, and compounding effects. Each asset class (e.g., equities, bonds, real estate) may require unique modifications to the basic formula:
Portfolio managers document these calculations in standardized reports to ensure transparency and compliance with regulatory requirements (e.g., SEC, MiFID II).
The following steps outline the process, using defect rate reduction as a case study:

Practical Applications of Percentage Return Calculations Across Industries
Percentage return calculations serve as a universal metric for evaluating performance, efficiency, and impact across diverse sectors. From financial portfolios to operational metrics in manufacturing, these computations provide quantifiable insights that drive decision-making, optimize resource allocation, and measure progress toward strategic goals. Below are five critical real-world scenarios where percentage return calculations are indispensable, along with structured workflows and documentation templates tailored to each industry.
Five Critical Real-World Scenarios for Percentage Return Calculations
Percentage return metrics are applied where performance must be measured against a baseline or expected outcome. The following scenarios demonstrate their versatility:
Example Output: "The diversified equity portfolio achieved a 12.3% annualized return, outperforming the benchmark by 3.1%."
Example Output: "Implementation of Six Sigma reduced defect rates by 74% in Q3, translating to $2.1M in cost savings."
Example Output: "Defensive player’s tackle success rate improved by 18%, correlating with a 12% reduction in opponent scoring."
Workflow for Calculating Percentage Return in Portfolio Management
Portfolio managers use percentage return to evaluate asset performance, adjust allocations, and communicate results to stakeholders. The workflow integrates time horizons, formula adjustments, and asset-specific considerations.
Asset Class
Time Horizon
Formula Adjustments
Example
Public Equities
Quarterly/Annual
"Stock A grew from $50 to $62 in 6 months (+24%), outperforming the sector average (+18%). After inflation (2%), real return = 22%."
Fixed Income (Bonds)
Monthly/Yearly
"Corporate bond portfolio returned 5.8% annually, with 3.2% from coupons and 2.6% from price appreciation. After 1.5% fees, net return = 4.3%."
Private Equity/Real Estate
3–10 Years
"Venture fund’s IRR over 5 years = 19.8%, exceeding the 15% hurdle rate. After 1.8% annual fees, investor return = 18%."
Cryptocurrencies
Daily/Volatile Periods
"Bitcoin’s 6-month return = 45%, but after 0.3% trading fees and 2% inflation, real return = 42.4%."
Percentage Return in Quality Control: Defect Rate Reduction Workflow
Manufacturers and production lines use percentage return to quantify improvements in defect rates, yield, or process efficiency. The workflow compares pre-intervention and post-intervention metrics, with adjustments for sample size and variability.
Formula: (Defective Units / Total Units) × 100
Formula: [(Baseline Rate − New Rate) / Baseline Rate] × 100
Example: [(4.2 − 1.1) / 4.2] × 100 = 73.8% reduction
Formula: Reduction % × (Defect Cost per Unit × Annual Volume)
Quality teams present these findings in dashboards or reports to justify process changes to leadership. For example:
*"Lean Six Sigma reduced defect rates from 4.2% to 1.1% in Assembly Line B, saving $180,000 annually. Root cause: 80% of defects traced to misaligned j
Advanced Methods and Adjustments in Percentage Return Calculations
Percentage return calculations extend beyond basic arithmetic to incorporate real-world financial adjustments, ensuring accuracy in performance evaluation. Advanced methods account for inflation, taxation, and transaction costs, while distinguishing between periodic and compounded returns. These refinements are critical for investors, portfolio managers, and financial analysts to make informed decisions under varying market conditions and regulatory frameworks.
Adjusting Percentage Returns for Inflation: Real vs. Nominal Returns
Inflation erodes purchasing power, making nominal returns insufficient for assessing true investment performance. The real return adjusts for inflation by subtracting the inflation rate from the nominal return, providing a measure of growth in constant-dollar terms. This adjustment is essential for long-term financial planning, retirement projections, and cross-period comparisons.The real return formula is derived as follows:
Real Return = (1 + Nominal Return) / (1 + Inflation Rate) – 1For example, an investment yielding a 7% nominal return in a year with 2% inflation generates a real return of approximately 4.90% using the exact formula. Historical data from the U.S. Bureau of Labor Statistics (BLS) shows that average annual inflation over the past 50 years (~3.5%) significantly impacts nominal returns, particularly in high-inflation decades like the 1970s.
or equivalently:
Real Return ≈ Nominal Return – Inflation Rate (for small inflation rates).
After-Tax Return Calculations for Different Tax Brackets
Taxes reduce net investment returns, and their impact varies by jurisdiction, asset type, and investor tax bracket. The after-tax return is calculated by deducting tax liabilities from gross returns, with tax rates applied to capital gains, dividends, or interest income based on holding periods and tax laws. Below is a structured comparison for common tax scenarios in jurisdictions with progressive taxation (e.g., U.S., Canada, or EU):
After-Tax Return = Gross Return × (1 – Tax Rate)Key Considerations:
Tax Rate (%) Gross Return (%) Tax Impact (%) Net Return (%) 0 (Tax-free) 10 0 10 10 10 1.0 9.0 15 10 1.5 8.5 20 10 2.0 8.0 25 10 2.5 7.5 30 10 3.0 7.0 35 10 3.5 6.5 40 10 4.0 6.0
Short-term vs. long-term capital gains: Long-term gains (held >1 year in the U.S.) are taxed at lower rates (0%, 15%, or 20%) compared to short-term gains (ordinary income rates). Dividend taxation: Qualified dividends (U.S.) are taxed at long-term capital gains rates, while non-qualified dividends are taxed as ordinary income. Deferral strategies: Tax-advantaged accounts (e.g., IRAs, 401(k)s) allow returns to compound without immediate taxation, altering the effective after-tax return. Annualized vs. Periodic Returns: Compounding Frequency and Time Weighting
The frequency of compounding—whether monthly, quarterly, or annually—directly affects the effective annual return. Annualized returns standardize periodic returns to a yearly basis, enabling comparability across investments with different holding periods. Two primary methods exist:1. Arithmetic Annualization:
Multiplies the periodic return by the number of periods in a year (e.g., monthly return × 12). This method understates true compounded growth but is simple and widely used for short-term comparisons.Arithmetic Annualized Return = Periodic Return × Number of Periods2. Geometric Annualization (Compounded Annual Growth Rate - CAGR):
Accounts for compounding by solving for the constant annual rate that would yield the same cumulative return over the period. CAGR is preferred for long-term performance evaluation.CAGR = (Ending Value / Beginning Value)^(1 / Number of Years) – 1Example Comparison:
A portfolio with monthly returns of 1% (arithmetic) annualizes to 12%, but the geometric return (assuming no volatility) would be: CAGR = (1.01)^12 – 1 ≈ 12.68%.When to Use Each:
Arithmetic returns are suitable for short-term analysis, risk assessment, or when volatility is negligible. Geometric returns are critical for long-term projections, retirement planning, and benchmarking against indexed returns (e.g., S&P 500 CAGR of ~10% over 50 years). Geometric vs. Arithmetic Mean Returns: Theoretical vs. Practical Applications
The choice between geometric and arithmetic means depends on the context of return calculation and the presence of volatility or compounding effects.
Arithmetic Mean Return:Appropriate Use Cases:
Measures the average return per period without accounting for compounding. It overstates expected future returns in volatile markets because it assumes returns can be averaged without sequence risk.Arithmetic Mean = Σ(Returns) / Number of PeriodsGeometric Mean Return:
Reflects the compounded growth rate over time, adjusting for the impact of volatility and return sequencing. It is the appropriate measure for long-term investment performance.Geometric Mean = (Product of (1 + Returns))^(1/Number of Periods) – 1
Arithmetic mean is used for: Short-term performance attribution. Estimating expected returns in low-volatility environments (e.g., Treasury bills). Calculating volatility (standard deviation) for risk models. Geometric mean is used for: Long-term portfolio projections (e.g., 20-year retirement planning). Comparing investment strategies with varying compounding periods. Evaluating hedge fund or private equity performance (where returns are irregular). Example:
A portfolio with returns of 20%, –10%, and 15% over three years has:
Arithmetic mean = (20 – 10 + 15) / 3 = 11.67% (overstates future expectations). Geometric mean = (1.20 × 0.90 × 1.15)^(1/3) – 1 ≈ 8.96% (accurately reflects compounded growth). Decision Tree for Selecting the Correct Percentage Return Method
The appropriate return calculation method depends on the type of input data, time horizon, and objective of the analysis. Below is a structured decision tree to guide selection:1. Input Data Type:
Discrete Returns (Fixed Periods): Use geometric mean for long-term compounded growth (e.g., annualized CAGR). Use arithmetic mean for short-term volatility analysis or expected return estimation. Continuous Returns (Intraday/High-Frequency): Apply logarithmic returns (ln(1 + R)) for statistical modeling (e.g., Black-Scholes option pricing). Convert to arithmetic/geometric means for periodic reporting. 2. Time Horizon:
Short-term (<1 year): Prefer arithmetic annualization for simplicity and comparability. Long-term (>5 years): Use geometric mean (CAGR) to reflect compounding effects accurately. 3. Adjustment Requirements:
Inflation Adjustment Needed: Calculate real return using the nominal return and inflation rate. Tax Impact Relevant: Deduct taxes using jurisdiction-specific rates (e.g., capital gains, dividends). Fees/Costs Present: Subtract expense ratios or transaction costs from gross returns before tax adjustments. 4. Objective of Analysis:
Performance Benchmarking: Use geometric returns for consistency with indexed benchmarks (e.g., MSCI World). Risk Assessment: Combine arithmetic returns with standard deviation for volatility metrics. Regulatory Reporting: Follow GAAP/IFRS guidelines (e.g., time-weighted returns for fund managers). Example Path:

Common Pitfalls and Validation Techniques in Percentage Return Calculations
Percentage return calculations are fundamental to financial analysis, investment evaluation, and performance benchmarking. Despite their apparent simplicity, errors in these computations can lead to misleading conclusions, misallocation of resources, or regulatory non-compliance. Common mistakes often stem from misapplied formulas, overlooked assumptions, or procedural oversights. Validation techniques, including cross-verification, sanity checks, and unit consistency assessments, serve as critical safeguards against such inaccuracies. This section examines five frequent errors in percentage return calculations, provides corrected examples, and introduces a structured validation framework to ensure accuracy and reliability.
Five Frequent Errors in Percentage Return Calculations
Misinterpretations and procedural oversights in percentage return calculations can distort financial assessments. Below are five recurring errors, each accompanied by a corrected example to illustrate the proper approach.Incorrect Divisor in Simple Return Calculations
A common mistake involves misidentifying the divisor in the basic percentage return formula:Simple Return = (Final Value – Initial Value) / Incorrect DivisorFor instance, dividing by the final value instead of the initial value inflates returns artificially. This error is particularly prevalent in scenarios where the initial investment is not explicitly tracked.Incorrect Example: Initial Investment (P) = $1,000; Final Value (F) = $1,500.
Miscalculation: (1,500 – 1,000) / 1,500 = 33.33% return (incorrect).
Corrected Calculation: (1,500 – 1,000) / 1,000 = 50% return (correct).Ignoring Compounding Effects in Multi-Period Returns
Percentage returns calculated over multiple periods often fail to account for compounding, leading to understated or overstated performance metrics. The arithmetic mean of periodic returns does not reflect the true compounded growth.Incorrect Example: Year 1 Return = 10%; Year 2 Return = 20%.
Miscalculation: (10% + 20%) / 2 = 15% average return (arithmetic mean, incorrect).
Corrected Calculation: Compound Annual Growth Rate (CAGR) = [(1 + 0.10) × (1 + 0.20)]^(1/2) – 1 = 14.89% (correct).Miscounting Time Periods in Annualized Returns
Annualizing returns without adjusting for the actual holding period length can produce misleading benchmarks. For example, treating a 6-month return as annual without scaling distorts comparative analysis.Incorrect Example: 6-Month Return = 20%.
Miscalculation: Treating 20% as annual return (incorrect).
Corrected Calculation: Annualized Return = (1 + 0.20)^(12/6) – 1 = 44% annualized return (correct).Overlooking Transaction Costs and Fees
Percentage returns that exclude fees, commissions, or taxes provide an unrealistic "gross" performance metric. Net returns, which account for all deductions, offer a more accurate reflection of investor profitability.Incorrect Example: Gross Return = 30%; Transaction Fees = 5% of initial investment.
Miscalculation: Reporting 30% return without deducting fees (incorrect).
Corrected Calculation: Net Return = [(1 + 0.30) × (1 – 0.05)] – 1 = 23.5% net return (correct).Misapplying Percentage Change Formulas for Negative Returns
Negative returns require careful handling to avoid mathematical inconsistencies, such as division by zero or incorrect sign conventions. For instance, a 50% loss followed by a 100% gain does not return to the original value due to the asymmetric nature of percentage changes.Incorrect Example: Initial Investment = $100; After 50% loss = $50; After 100% gain = $100.
Misinterpretation: "A 50% loss and a 100% gain cancel out" (incorrect).
Corrected Understanding: Net Return = [(1 – 0.50) × (1 + 1.00)] – 1 = 0% return, but the path matters—intermediate losses reduce the base for subsequent gains.
Checklist for Validating Percentage Return Calculations
A systematic validation process minimizes errors and enhances the credibility of percentage return analyses. Below is a checklist to ensure calculations are accurate, consistent, and contextually appropriate.Cross-Verification with Alternative Formulas
Percentage returns can be computed using multiple equivalent formulas. Cross-verifying results across methods (e.g., simple return vs. logarithmic return) confirms consistency and identifies discrepancies.Key Actions:
Apply the simple return formula: (F – P)/P. Use logarithmic return: ln(F/P). For multi-period returns, compare arithmetic mean vs. geometric mean (CAGR). Ensure all methods yield comparable results within acceptable rounding tolerances. Sanity Checks for Plausibility
Basic logical checks can reveal obvious errors, such as returns exceeding 100% without corresponding extreme price movements or negative returns that defy market conditions.Examples of Sanity Checks:
A 100% return in a single period implies the final value doubled; verify if this aligns with market data. A negative return greater than 100% (e.g., –150%) implies the final value is negative; confirm if this reflects short selling or liquidation. Compare calculated returns against peer benchmarks (e.g., industry averages) for reasonableness. Unit Consistency and Time Alignment
Percentage returns must align with the time periods under analysis. Mismatched units (e.g., monthly returns annualized incorrectly) lead to distorted comparisons.Verification Steps:
Confirm the time horizon matches the frequency of returns (e.g., quarterly returns should not be treated as annual). Ensure denominators in formulas (e.g., initial value) correspond to the correct period. For compounding, verify that the exponent aligns with the number of periods (e.g., ^(1/3) for triennial returns). Documentation of Assumptions and Adjustments
Transparent recording of assumptions (e.g., reinvestment rates, fee structures) prevents ambiguity and facilitates reproducibility.Required Documentation:
Specify whether returns are gross or net of fees/taxes. Note any adjustments for dividends, splits, or currency fluctuations. Clarify the treatment of compounding (e.g., annual vs. continuous). Diagnostic Table for Troubleshooting Calculation Discrepancies
Discrepancies in percentage return calculations often stem from systematic errors. The following table provides a structured approach to identifying symptoms, pinpointing likely causes, and applying corrective measures.
Symptom Likely Cause Solution Example Fix Calculated return exceeds 100% without proportional price movement. Incorrect divisor (using final value instead of initial value). Recompute using initial value as the denominator. Original: (F – P)/F → Corrected: (F – P)/P.Multi-period returns do not match single-period compounding. Arithmetic mean used instead of geometric mean (CAGR). Calculate CAGR for accurate compounded return. Original: (R1 + R2)/2 → Corrected: [(1 + R1)(1 + R2)]^(1/n) – 1.Annualized return does not scale with holding period. Incorrect exponent for time adjustment. Apply exponent equal to 1/(number of periods). Original: R_monthly × 12 → Corrected: (1 + R_monthly)^12 – 1.Net return differs significantly from gross return. Fees or costs not accounted for in the calculation. Deduct fees as a percentage of the initial or final value. Original: (F – P)/P → Corrected: [(F – Fees) – P]/P.Negative return after a gain does not reflect intermediate losses. Visualization and Reporting of Percentage Return
Effective visualization and reporting of percentage return enhance decision-making by transforming raw numerical data into actionable insights. Clear graphical representations, dashboards, and infographics contextualize performance trends, facilitate comparisons, and highlight critical events. This section explores methods to design informative visualizations, including line graphs, interactive dashboards, and infographics, while ensuring accuracy, readability, and strategic emphasis.
Line Graphs for Temporal Percentage Return Analysis
Line graphs are ideal for illustrating percentage return trends over time, enabling stakeholders to identify patterns, volatility, and significant events. Properly labeled axes, annotated data points, and contextual markers (e.g., market crashes) improve interpretability.Key Components of an Effective Line Graph:
X-Axis (Time): Represent periods (e.g., monthly, quarterly, annually) with consistent intervals. For long-term data, use logarithmic scales to accommodate exponential growth or declines. Y-Axis (Percentage Return): Display values in percentage terms, with a baseline at 0% for clarity. Include both positive and negative ranges to capture losses. Data Points: Plot returns at discrete intervals (e.g., end-of-period values) and connect them with smooth lines. Use markers (e.g., circles, squares) to distinguish between actual and projected returns. Annotations: Highlight key events (e.g., economic crises, policy changes) with vertical lines or callouts. For example: 2008 Financial Crisis: A sharp negative spike in Q4 2008, followed by gradual recovery. COVID-19 Pandemic: Volatility in Q1 2020, with a subsequent rebound in Q2. Trend Lines: Add moving averages (e.g., 3-month, 12-month) to smooth fluctuations and reveal underlying trends. Example Data Structure for a Line Graph:
Visual Best Practices:
Period Return (%) Event Annotation Q1 2020 -12.5 COVID-19 Market Crash Q2 2020 +28.7 Recovery Phase Q4 2022 +5.3 Inflation Adjustments
Use contrasting colors for positive (green/blue) and negative (red/orange) returns. Include a legend if multiple series (e.g., "Portfolio A vs. Benchmark") are compared. Avoid clutter by limiting annotations to 3–5 major events per graph. Dashboard Design for Percentage Return Reporting
Dashboards consolidate key metrics, interactive controls, and conditional formatting to provide a real-time snapshot of performance. A well-structured dashboard balances quantitative rigor with user-friendly design.Core Elements of a Percentage Return Dashboard:

Use the formula: ((Current Value – Original Cost) / Original Cost) × 100. For example, if you invested $1,000 and it’s now worth $1,200, the return is ((1,200 – 1,000) / 1,000) × 100 = 20%. Include dividends or income if applicable by adding them to the current value before calculating.
What’s the formula to calculate the percentage return on a stock?
For a stock, subtract the purchase price from the current price, divide by the purchase price, then multiply by 100: ((Selling Price – Buy Price) / Buy Price) × 100. Include reinvested dividends if tracking total return. For example, buying at $50 and selling at $65 with $5 in dividends gives ((65 + 5 – 50) / 50) × 100 = 40%.
How do you calculate the percentage return on an investment property?
Use the cash-on-cash return formula: (Annual Net Income / Total Cash Invested) × 100. For appreciation, use ((Sale Price – Purchase Price + Mortgage Paydown) / Total Cash Invested) × 100. Annual net income includes rent minus expenses (taxes, insurance, maintenance, etc.).
What is the formula to calculate return percentage?
The basic formula is ((Final Value – Initial Value) / Initial Value) × 100. For investments with income (like stocks or bonds), add income received to the final value before calculating. Example: A $10,000 investment grows to $12,000 with $500 in dividends yields ((12,000 + 500 – 10,000) / 10,000) × 100 = 15%.
How can I calculate percentage return in Excel?
Use the formula `=(Current_Value - Original_Cost)/Original_Cost` in a cell, then multiply by 100 or format as a percentage. For total return (including income), use `=(Current_Value + Income - Original_Cost)/Original_Cost`. Example: `=(B2 + C2 - A2)/A2` where A2 is cost, B2 is current value, and C2 is income.
How do you calculate percent return on investment?
Divide the net profit (or loss) by the original investment amount, then multiply by 100: ((Profit / Original Investment) × 100). Profit equals final value minus initial cost plus any income (dividends, interest, rent). Example: A $5,000 investment earning $700 in profit gives ($700 / $5,000) × 100 = 14%.
