How this calculation works
Compound interest is the addition of interest to the principal sum of a loan or deposit. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.
The formula used in this calculator is a monthly compounding model that assumes contributions are made monthly and interest compounds monthly against the running balance.
