ROI Calculator
Calculate Return on Investment (ROI), total profit, and annualized return from an initial investment and ending value.
Run tool
This online ROI calculator computes total return on investment, net profit, and annualized rate of return based on your initial capital, final value, and holding period. Measuring investment performance requires comparing the ending balance against the principal amount. When evaluating real estate, stocks, mutual funds, or equipment purchases over multiple years, raw total return does not reveal how capital performed year by year. By entering the starting balance, final ending value, and investment duration in years, you obtain both overall percentage return and annualized compound growth. The calculator handles gains and losses by comparing your ending balance to the starting principal. For multi-year holdings, the annualized return metric standardizes performance across different time horizons, allowing straightforward comparisons between short-term trades and long-term investments. Values are rounded to two decimal places for clear financial tracking.
Instructions
- Enter the initial investment amount, which must be greater than zero.
- Enter the final value of the investment, representing your ending balance rather than net gain.
- Enter the holding period in years as a positive number.
- Select Calculate to generate total profit, percentage return, and annualized return.
Examples
- An initial investment of $1,000 growing to a final value of $2,000 over 5 years yields a total ROI of 100.00% and an annualized return of 14.87%.
- An initial investment of $5,000 that increases to $6,500 over 2 years generates a profit of $1,500, resulting in an ROI of 30.00% and an annualized return of 14.02%.
FAQ
What is the difference between total ROI and annualized return?
Total ROI measures the overall percentage gain or loss across the entire investment period. Annualized return calculates the geometric average yearly growth rate, allowing you to compare investments held for different lengths of time.
How does the calculator interpret final value?
The final value field represents the total ending worth of your investment, including returned principal. It is not the net profit amount.
Can I calculate returns for periods shorter than one year?
Yes, you can enter fractional years such as 0.5 for six months, provided the value is greater than zero.
What happens if an investment loses money?
If the final value is lower than the initial investment, the calculator displays a negative profit and a negative ROI percentage.
