Return on investment (ROI) measures how much you gained compared with what you put in. It helps decide whether a machine, marketing campaign, property or other investment was worth it.
Total ROI ignores time. Annualised ROI converts it into a yearly rate, so a 50% return over three years can be compared fairly with a 20% return over one year.
ROI % = (Return − Investment) ÷ Investment × 100 · Annualised = (Return ÷ Investment)^(1 ÷ Years) − 1
ROI % = (Gain − Investment) ÷ Investment × 100.
The equivalent yearly rate of return, calculated like CAGR, allowing investments of different lengths to be compared.
It depends on risk and alternatives. At minimum, ROI should beat your borrowing cost and safer options.
(Profit from campaign − campaign cost) ÷ campaign cost × 100, using gross profit rather than revenue.
