About ROI Calculator
Return on investment tells you how much you gained relative to what you put in. This ROI Calculator on TheToolss computes your net profit and ROI percentage from the amount invested and the final value, and — when you enter a holding period — the annualized ROI so you can compare investments of different durations fairly. Use it for stocks, business projects, marketing spend, or any investment. The result updates instantly. It runs in your browser — free, private, and no signup.
