Guide: ROI Calculator

What it does

Converts profit or value change into an ROI percentage relative to cost.

How to use it

Formula

ROI = (Gain – Cost) ÷ Cost × 100%.

Example

Invest $1,000, sell for $1,250 → ROI = 25%.

FAQs

Does ROI include time?

Include transaction costs in cost basis for realistic ROI.

Can ROI be negative?

Yes—if you lose money versus cost, ROI is negative.
