About the UK Investment Growth Calculator
Use this investment growth calculator to estimate how a starting balance and regular monthly contributions could grow under an assumed constant annual return.
Compound growth means investment returns can themselves earn returns over time. Monthly contributions increase the amount invested and can raise the estimated future value. A longer investment period usually increases the effect of compounding, all else equal.
Assumed returns are scenarios you choose, not forecasts. Actual investment returns vary with markets, fees, timing and risk. Historical performance, including long-term US stock market averages around 10% nominal in some periods, does not predict future results.
If you later sell investments, tax may apply. See the Capital Gains Tax Calculator. For borrowing estimates, try the Mortgage Repayment Calculator or Loan Repayment Calculator.
