Compound interest is one of the most powerful forces in personal finance. It means your interest earns interest—and over time, small amounts can grow into serious wealth.
Use this Compound Interest Calculator to estimate how much your money could grow based on your starting amount, interest rate, time horizon, and compounding frequency.
Example Scenario
Let’s say you invest $10,000 at 8% annually for 15 years, compounded monthly:
Formula: FV = 10000 × (1 + 0.08/12)^(15×12)
Result: ~$32,000
That’s the power of compound growth—without adding another dime!
