ROI = (return − investment) ÷ investment. Annualized ROI normalizes the result to a per-year rate, so investments held for different periods can be compared fairly — useful for comparing a 6-month marketing campaign against a 2-year equipment purchase, for example.

ROI Calculator computes net profit and return-on-investment percentage from an initial investment and final value, plus an annualized ROI that normalizes results to a per-year rate — so a 6-month campaign and a 2-year purchase can be compared on equal footing instead of just raw percentages.
