What is the ROI Calculator?
ROI Calculator is a free online tool that calculate return on investment (ROI %), net profit, and annualized ROI from cost and gain or.
An ROI (return on investment) calculator measures how much you gained or lost relative to what you spent. The classic formula is ROI % = (net gain ÷ cost) × 100. You can also start from a final value: net gain = final value − cost.
Enter cost and either net gain or final value, optionally add a holding period in years, and get ROI %, net gain, final value, return multiple, annualized ROI (compound), and simple annual ROI. A reverse section shows the gain needed for a target ROI. All math runs in your browser on Mytulify — useful for planning, not investment advice.

- Enter your initial investment (cost) and the matching gain or ending value.

Frequently asked questions
What is an ROI calculator?
An ROI calculator computes return on investment as a percentage of cost, plus related figures like net gain, final value, and optionally annualized ROI over a holding period.
How is ROI calculated?
ROI % = (net gain ÷ cost) × 100, where net gain is profit (or loss) relative to the initial investment. If you enter final value instead, net gain = final value − cost.
What is annualized ROI vs simple annual ROI?
Annualized ROI compounds growth over the holding period (similar to CAGR when final value is positive). Simple annual ROI divides total ROI % by years with no compounding.
How is ROI different from profit margin?
ROI divides gain by cost (what you invested). Profit margin divides profit by selling price (revenue). Use ROI for investment efficiency and margin for pricing/sales profitability.
Is this ROI calculator free?
Yes. Unlimited use in your browser on Mytulify — no signup and no data uploaded to a server.
