How Compound Interest Works
Our compound interest calculator shows how your investment grows over time when interest is earned on both your principal and previously accumulated interest. This "interest on interest" effect is the foundation of long-term wealth building.
The Power of Compounding
The more frequently interest compounds, the faster your investment grows:
- Daily: Interest calculated and added 365 times per year
- Monthly: Compounds 12 times per year
- Quarterly: Compounds 4 times per year
- Annually: Compounds once per year
Regular Contributions Make a Big Difference
Adding consistent monthly contributions accelerates growth significantly. Even small recurring deposits,combined with compound interest,can produce remarkable results over decades. Start early and stay consistent for best results.
