About this tool
This page opens the ROI calculator set up to annualize a result: type in what you started with, what you ended with and the holding period, and the per-year rate is the first number you see.
Annualizing matters whenever time spans differ. A 40% gain in three years and a 60% gain in five years look incomparable until both are turned into yearly rates — 11.87% and 9.86% — and suddenly the slower-sounding investment is the better one. Fractional periods work too: 18 months is simply 1.5 years.
Alongside the annualized rate you get the total ROI, the profit and the doubling time at that pace, all computed in your browser without any data leaving it.
Example. An investment that goes from 200 to 250 shows a 25 percent ROI and a profit of 50.
Limit. CAGR and the rule-of-72 doubling comparison appear only when a positive holding period is supplied, and the starting amount must be greater than zero.
