Calculate return on investment from cost and return figures, with net profit, ROI percentage and — where a holding period is given — the annualised return that makes comparison meaningful.
Getting started
Enter the total amount invested and the total value returned.
Add the holding period in years to get an annualised figure.
Compare the annualised return rather than the headline ROI when investments ran for different lengths of time.
Why it helps
Annualised return makes investments of different durations genuinely comparable.
Net profit is shown separately from the percentage, which prevents a common misreading.
Works equally well for marketing spend, equipment purchases and financial investments.
In practice
Evaluating whether an advertising campaign paid for itself.
Comparing two equipment purchases with different costs and lifespans.
Reporting investment performance to a partner or board.
Everything people ask most about the roi calculator, answered plainly.
