Compound interest example
A starting deposit of 1,000 at 5% compounded annually for two years, with no additional contributions, grows to 1,102.50. The second year earns interest on 1,050.
Choose a compounding frequency and enter your monthly contribution. The calculator assumes deposits are made at the end of each month and uses a constant annual rate.
How it works
The annual rate is nominal. Deposits are added at the end of each month; the monthly growth factor is derived from your selected compounding schedule.
