Investment growth calculator

Calculate how your wealth grows through compound interest, including monthly contributions.

How does compound interest work?

When investing, you receive a return on your deposited money. In the following period, you receive a return on your original amount as well as on previously earned returns. This is called compound interest.

Calculation used

The calculation is performed on a monthly basis:

Final value = Starting capital × (1+r)^n + Deposit × [((1+r)^n − 1) / r]

Whereby:

  • r = monthly return (annual return / 12)
  • n = total number of months
