Calculate total and annualized return on investment.
📈 ROI = total return. Annualized = yearly average (CAGR). For stocks & real estate.
ROI (Return on Investment) measures how much profit an investment made relative to its cost. This calculator shows total ROI and annualized return (CAGR), so you can compare investments held for different lengths of time.
Total ROI doesn't account for time. A 50% gain in 1 year is excellent; the same 50% gain over 10 years is mediocre (~4% annually). Annualized return (CAGR) lets you compare a 5-year stock investment to a 20-year real estate one on equal footing.

Browser-based tools like this one have a few real advantages over installed software or manual methods:
The ROI Calculator is based on the following formula:
ROI = (Gain − Cost) / Cost × 100%
Variables: ROI = Return on investment (%) Gain = Final value of the investment ($) Cost = Original amount invested ($)
Return on investment. Gain = final value − cost (or sale price − purchase price). Expressed as a percentage of the original cost.
Worked example: Step 1: Cost = $2,000, final value (Gain) = $2,500. Step 2: profit = 2,500 − 2,000 = $500. Step 3: ROI = 500 / 2,000 × 100% = 25%. Result: the investment returned 25% — $1.25 back for every $1.00 invested.
