COMPOUNDING

Back to Glossary

Definition

The process by which an investment’s earnings generate additional earnings over time.


Summary

Compounding is often called 'earning interest on interest' - it's the snowball effect where your investment gains start earning their own gains. When you invest money, you earn returns on your original investment. With compounding, those returns stay invested and generate their own returns, creating exponential growth over time. The longer your money compounds and the more frequently it compounds, the more dramatic the growth becomes. This is why starting to invest early, even with small amounts, can be incredibly powerful.

Usage Context

Understanding compounding is crucial when learning about investment planning, retirement savings, loan interest calculations, and making informed financial decisions. It's fundamental to concepts like present and future value calculations and helps explain why time is such an important factor in building wealth.

  • Thinking compounding and simple interest are the same thing
