ROI calculator.
Measure net investment return and an annualized equivalent.
ROI inputs
Net ROI = (final value + income − additional costs − initial cost) ÷ initial cost. Annualization treats net proceeds as received at the end. It is not IRR when cash flows occur on different dates.
How this roi calculator works
ROI compares net profit with the initial cost. Net profit includes final value and received income, less additional fees and initial cost. Annualization converts the total growth factor into an equivalent yearly rate over the holding period.
A worked example
Investing 10,000 and receiving 12,000 at the end, with 500 income and 100 fees, yields 2,400 profit and 24% ROI. Over two years the annualized equivalent is about 11.36%.
Is annualized ROI the same as IRR?
Only under compatible cash-flow timing assumptions. This calculation treats proceeds as received at the end and does not solve returns from dated deposits or withdrawals. Negative net proceeds do not have a real annualized growth rate here.
