Formula and method
ROI = (final value − initial investment − costs) / (initial investment + costs) × 100. Annualized ROI = ((final / total cost)^(1 / years) − 1) × 100.
Worked example
An investment of 1,000 plus 100 in costs returned as 1,300 earns 200, or 18.18% total ROI.
What the result assumes
Annualization treats all costs as paid at the start and all proceeds as received at the end. It is not an IRR calculation for timed cash flows.
Common question
Does a positive ROI mean an investment is suitable?
ROI describes the entered values. It does not measure risk, liquidity, inflation, or future performance.
