Investment Calculator (ROI)

Calculate your return on investment (ROI) and annualized return (CAGR) from an initial amount, final value, and time held.

Frequently Asked Questions

How do you calculate ROI?

ROI = (Final Value - Initial Investment) / Initial Investment x 100. It shows your total percentage gain or loss over the entire holding period.

What is CAGR and how is it different from ROI?

CAGR (Compound Annual Growth Rate) spreads your total return evenly across each year: CAGR = ((Final / Initial)^(1/years) - 1) x 100. Unlike simple ROI, it lets you compare investments held for different lengths of time.

Is ROI the same as ROAS?

No — ROI measures overall profitability of an investment, while ROAS (Return on Ad Spend) measures revenue generated per dollar of advertising spend. See our <a href="/roas-calculator">ROAS calculator</a> for ad-spend specific returns.
