📊 ROI Calculator

About this ROI Calculator

ROI — return on investment — is the simplest measure of whether a deal, a product line or an investment was worth it: profit divided by the amount invested, shown as a percentage. This calculator gives you the ROI and the actual money profit or loss, so you can compare opportunities of different sizes on one fair scale.

How to use it

1. Enter the total amount you put in, including purchase cost and any direct expenses.
2. Enter the total amount you got back — sale price, payouts or final value.
3. Click Calculate ROI.
4. Compare the percentage against your other options and against simply keeping the money in a savings account.

Example

Investing 100,000 and getting back 135,000 is a profit of 35,000, which is an ROI of 35%.

Frequently asked questions

Does ROI account for time?

No. A 35% ROI over one year is excellent; over ten years it is weak. For time-adjusted comparisons, use the CAGR calculator, which gives a per-year rate.

What is a good ROI?

It depends on risk and time. As a rough guide, a business investment that returns less than a safe bank deposit rate over the same period is rarely worth the risk and effort.
