ROI Calculator
Calculate the return on investment (ROI) and net gain between an initial investment and its final value.
ROI
25%
- Net gain
- £2,500
Assumptions
- Does not account for the time value of money — use CAGR for a rate that reflects time held
How it's calculated
ROI % = ((final value − initial investment) / initial investment) × 100.
Worked example
An £10,000 investment that grows to £12,500 has a 25% ROI and a £2,500 net gain.
Frequently asked questions
Does ROI account for how long I held the investment?
No — ROI is a simple total-return percentage. The CAGR calculator annualizes returns to account for holding period.
