Investment Return Calculator
Calculate total return, percentage return, and annualized return on an investment.
How this calculator works
How to use this calculator
Enter your initial investment, ending value, additional contributions, and investment period in years. The calculator estimates total return, percentage return, and annualized return.
Formula used
Total Return = Ending Value − Total Invested. Percentage Return = Total Return ÷ Total Invested × 100. Annualized Return = (Ending Value ÷ Total Invested)^(1 / years) − 1.
Example calculation
If you invest $5,000, add $1,000, and the ending value is $7,500 after 3 years, total return is $1,500, percentage return is 25%, and annualized return is about 7.72% per year.
What the result means
Total return shows the overall gain or loss. Annualized return converts the result into an estimated yearly growth rate, assuming steady compounding.
Frequently asked questions
Does this handle multiple contribution dates?
No. It treats additional contributions as part of total invested capital, not as timed cash flows.
Is annualized return the same as average return?
No. Annualized return accounts for compounding, while a simple average does not.
Does this include taxes or fees?
No. Enter net values if you want to account for fees or taxes manually.
