Compound Interest Calculator

See how compound interest can grow a starting balance and compare different compounding frequencies.

How it works

  • Uses A=P(1+r/n)^(nt).
  • The selected frequency determines how many times interest is applied each year.
  • The estimate assumes a constant rate.

Example

See how RM10,000 grows at 5% for 10 years with monthly versus annual compounding.
