How this is worked out
Return on investment is (amount returned − amount invested) ÷ amount invested × 100.
Worked example
- Invested £5,000.00
- Returned £6,500.00
(6,500 − 5,000) ÷ 5,000 × 100
30% return, a profit of £1,500.00
Assumptions and limits
- This is a simple return over the whole period, not an annualised figure, so it cannot be compared directly with an annual interest rate.
- Tax, fees and inflation are not deducted.
