Rate of Return Calculator
A $10,000 investment that grows to $11,500 and pays $300 in income has an 18% total return. If that happened over 3 years, the annualized return is 5.67%. This rate of return calculator measures the full percentage gain or loss from a starting value, ending value, and optional income such as dividends or interest. Add years held when you want to translate that full-period return into an annualized rate.
Quick answer
Total return measures the full gain or loss across the whole holding period.
Total return includes ending value plus any income received. Annualized return appears only when you enter years held.
What this tells you
- •Total return measures the full gain or loss across the whole holding period.
- •Income such as dividends, interest, or distributions should be added to the ending value when you calculate total return.
- •Annualized return is different. It restates the full return as an even yearly rate so you can compare periods of different lengths.
How to Use
- 1Enter the starting value at the beginning of the period.
- 2Enter the ending value at the end of the period. Use market value only if income was paid out separately.
- 3Enter any income received during the period, such as dividends or interest. Leave it at 0 if none was paid.
- 4Optionally enter years held to estimate annualized return, then calculate to see the full-period return and dollar gain or loss.
How It Works
Formula
Total return = ((Ending value + Income received - Starting value) ÷ Starting value) × 100
Annualized return = (((Ending value + Income received) ÷ Starting value)^(1 ÷ Years held) - 1) × 100Total return compares everything you finished with against what you started with. Annualized return takes that full-period result and converts it into an even yearly rate. That makes comparisons easier, but it does not mean the investment earned the same return every year.
Calculation note: values are processed in the order shown above, using the current input units.
Worked Examples
Stock fund with dividends over 3 years
The investor finished with $11,800 between market value and cash income. That is a $1,800 gain on a $10,000 starting value.
Bond fund loss with income over 2 years
Income softens the loss, but the combined ending value is still below the starting value, so both return figures stay negative.
Total return vs annualized return
These two percentages answer different questions.
| Metric | What it tells you | Best use |
|---|---|---|
| Total return | The full gain or loss from start to finish, including income | Checking how much you actually made or lost over one holding period |
| Annualized return | The full return restated as an even yearly rate | Comparing results across holding periods with different lengths |
If you made deposits or withdrawals during the period, use IRR or time-weighted return instead of a simple start-to-finish rate of return.
Common mistakes
- Leaving dividends or interest out of the return calculation
- Comparing a short holding-period return to a multi-year return without annualizing both
- Treating annualized return as the exact return earned in every single year
Limitations
This calculator assumes one starting value, one ending value, and optional income received during the period. Annualized return treats the full result as if it compounded evenly across the years entered. It does not account for deposits, withdrawals, fees, taxes, inflation, or the exact timing of income payments.
