How to use this calculator
Compare total profit, total return, and compound annual growth. Enter amounts in the units shown, select the applicable options, and click Calculate. Use Reset to restore the starting values.
Calculation formula
ROI = (returned − invested)/invested; annualized = (returned/invested)^(1/years) − 1.
Assumptions and accuracy
Review timing, rates, fees and result notes when comparing scenarios. Future returns and rates are assumptions rather than guaranteed outcomes. Monetary display follows the currency’s precision; intermediate calculations retain additional digits.

Calculate total ROI and an annualized return from the amount invested, amount returned and holding period. The total return and annualized rate answer different questions.
Worked examples
Calculate ROI from a 1,000 investment
Illustrative inputs are specified in the steps below; the example link loads the complete settings. Unmentioned settings use the linked defaults.
- Net gain is 1,200 − 1,000 = 200. ROI is 200 / 1,000 × 100 = 20%; at a one-year holding period the annualized rate is also 20%.
Return on investment: 20%.
Try these inputsCommon questions
Is a 50% ROI the same as 50% per year?
Only for a one-year period under the stated convention. A multi-year total return must be annualized to compare horizons.
Should fees be included in ROI?
Include them consistently in the money invested or net proceeds. Excluding material costs can overstate the gain.
Scope and assumptions
The simple model treats the entered investment and return as endpoints. Use a cash-flow method for multiple dated deposits and withdrawals.
