What is this Calculator?
A Compound Interest Calculator is a mathematical tool that demonstrates the "eighth wonder of the world"—compound interest. Unlike simple interest, which only pays interest on your original principal, compound interest pays you interest on your principal and on the accumulated interest from previous periods.
How it Works
The calculation is driven by compounding frequency. The more frequently interest is added to your balance, the faster your money grows. The standard formula is A = P(1 + r/n)^(nt).
Example Calculation
If you invest $10,000 at 8% annual interest for 20 years, with annual compounding you will end up with $46,609. But if that same 8% is compounded monthly, you will end up with $49,268. That's an extra $2,659 generated purely by changing the compounding frequency!
Benefits of Using This Tool
- Wealth Visualization: See how leaving your money untouched allows it to snowball over long periods.
- Investment Choice: Helps you understand why a 7% return compounded monthly might beat an 7.1% return compounded annually.
Frequently Asked Questions (FAQs)
Is compound interest better than simple interest?
