About this tool
This page opens the ROI calculator with the annualized result in front: enter what the investment was worth at the start, what it is worth now and how many years passed, and the compound annual growth rate leads the output.
CAGR answers a different question than total return. Doubling your money sounds great, but over five years it is 14.87% per year and over twenty years only about 3.5% — CAGR is the smoothed yearly rate (final/initial)^(1/years) − 1 that makes investments with different time spans comparable.
The calculator also prints the total ROI, the absolute profit and how long money needs to double at that rate — everything computed locally in your browser, with plain numbers that work in any currency.
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.
