How this investment return calculator works
This calculator projects the future value of a lump-sum investment plus optional regular contributions, applying a compound annual growth rate (CAGR). It shows nominal value, inflation-adjusted value and total contributions versus total growth.
- Future value = PV × (1 + r)^n, where r is the annual return and n is the number of years.
- Regular contributions are treated as an ordinary annuity: FV = PMT × [(1 + r)^n − 1] ÷ r.
- Adding the lump-sum and annuity future values gives the total projected portfolio value.
- Inflation adjustment deflates the nominal result by the assumed CPI growth rate.
Investment returns are variable and not guaranteed. Past performance of indices does not predict future results. This is a planning tool only.
