How to Calculate Cumulative Return
The cumulative return of an investment reflects the total percentage change in its price over a specific period. To determine this figure, use the formula: ((Current Price of Security - Original Price of Security) / Original Price of Security) * 100%. This calculation provides insight into the overall performance of your investment, factoring in all gains, losses, and reinvestments over the set timeframe.
Necessary Data for Calculation
To perform the cumulative return calculation accurately, start with the original and current prices of the security. If dividends or capital gains were reinvested, include these figures as they affect the total return. Additionally, remember taxes, fees, and other expenses can also impact the final result, as they reduce the effective return on the investment.
Calculation Tools and Methods
Various methods exist for calculating cumulative returns, with the Additive Profit Calculation method being notable for its directness. Besides manual calculations, financial software and investment tools can automate and simplify this process, ensuring that all variables, including reinvestments and distributions, are correctly factored in.
Understanding Cumulative Returns
With an example, if you had invested $10,000 in XYZ Widgets Company and after 10 years it turned into $48,000, the cumulative return calculation would be 380%. Such examples demonstrate how to apply the formula practically and underscore the importance of long-term investment perspectives in assessing performance.
Impact of External Factors
Consider how annual expenses, taxes, and investment fees might skew the cumulative return. Regular costs, particularly for managed investments like mutual funds, reduce net performance and therefore the cumulative return. Accurate and mindful computation is crucial for obtaining a clear picture of investment growth.
How to Calculate Cumulative Return
Understanding Cumulative Return
Cumulative return measures the total change in the price of an investment over a specified period. It includes the effects of dividends and interest when applicable, making it a comprehensive metric for assessing overall investment performance.
Calculating Cumulative Return
To calculate cumulative return, use the formula: Cumulative Return = (Current Price of Security - Original Price of Security) / Original Price of Security. If no dividends or interests are paid, use the raw closing price. For assets that yield dividends or interest, use the adjusted closing price, which accounts for these distributions.
Step-by-Step Calculation
Begin with identifying the original and current prices of the asset. If you are analyzing an asset with dividends or interest, ensure to use the adjusted closing prices. Subtract the original price from the current price, divide the result by the original price, and then multiply by 100 to get the percentage return.
Factors Affecting Cumulative Return
Keep in mind that reinvesting dividends or capital gains, taxes, and any annual fees excluded from return calculations can significantly influence the cumulative return. For precise assessment, consider these factors to understand the actual performance and growth of the investment.

Calculating Cumulative Return: Practical Examples
Example 1: Single Investment
Assume an initial investment of $1,000 in a stock that grows to $1,500 over one year. The cumulative return is calculated as follows: R = (1,500 - 1,000) / 1,000 = 0.5 or 50%.
Example 2: Multiple Period Investment
For an investment that generates returns of 10% in the first year and 5% in the second, with a starting value of $1,000, the calculation is: R = (1,000 * 1.10 * 1.05) / 1,000 - 1 = 1.155 - 1 = 0.155 or 15.5% cumulative return over two years.
Example 3: Portfolio Returns
Consider a portfolio initially worth $2,000, divided evenly between two stocks. If one stock grows by 20% and the other by 10%, the overall portfolio value is: 2,000 * (1/2 * 1.20 + 1/2 * 1.10) = 2,000 * 1.15 = 2,300. Thus, the cumulative return is (2,300 - 2,000) / 2,000 = 0.15 or 15%.
Example 4: Impact of Dividends
If an investment starts at $5,000, grows to $5,500, and pays $300 in dividends, the cumulative return is calculated by adding the growth and dividends, then dividing by the initial value: (5,500 + 300 - 5,000) / 5,000 = 0.16, or 16%.
Example 5: Negative Returns
If an investment of $1,000 decreases to $800, the cumulative return is R = (800 - 1,000) / 1,000 = -0.2 or -20%. Negative returns show a loss in the investment value over the period.
