Quick Guide

The Power of Compound Interest explained

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. 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.

Compound interest makes your money grow faster than simple interest. Our calculator helps you project your savings or investment growth with customizable compounding frequencies (daily, monthly, quarterly, or annually).

Compounding Projections

  • Custom compounding frequency: Daily, Monthly, Quarterly, Semi-Annually, or Annually.
  • Option to add regular monthly deposits to simulate savings growth.
  • Interactive growth chart visualizing principal vs compound interest.
  • Detailed annual amortization table.

How to Use the Compound Interest Calculator

  1. 1Enter your initial principal deposit amount.
  2. 2Input the annual interest rate.
  3. 3Select the compounding frequency from the dropdown.
  4. 4Set the investment duration in years, and optionally add a monthly contribution.

Crucial Compounding Variables

  • Higher compounding frequency (e.g. daily vs annual) leads to higher overall returns.
  • Taxes on interest earned can reduce your actual compounded net returns.
  • Inflation will reduce the real purchasing power of your final compounded amount.
