What Is Compound Interest?

Compound interest means earning interest not only on your original investment but also on the interest already added over time. This is why compounding is one of the most powerful concepts in long-term investing.

How This Compound Interest Calculator Works

This calculator estimates the future value of your money based on principal amount, annual interest rate, time period, compounding frequency, and inflation rate. It shows both nominal value and inflation-adjusted value.

FAQ

What is compound interest?

Compound interest is interest earned on both the original amount and previously earned interest.

What is the difference between simple and compound interest?

Simple interest is calculated only on the principal amount, while compound interest is calculated on principal plus accumulated interest.

Why does compounding frequency matter?

More frequent compounding usually increases the final amount because interest is added more often.
