ROILab

ROI Calculator

A free return-on-investment calculator that turns an amount invested or spent and an amount returned or earned into a clear net gain and ROI percent. Add a holding period in years and it also estimates the annualized (compound-per-year) return so a five-year deal and a one-year deal can be compared on the same footing. ROI is measured on the initial cost only, so it excludes fees, carrying costs, taxes, and reinvested cash flows. Everything runs in your browser; the result is an estimate for comparison, not financial, investment, or tax advice.
