The Power of Compound Interest in Investing
Discover how compound interest can exponentially grow your investments.
Compound interest is interest earned on both principal and accumulated interest.
The Compound Interest Formula
A = P(1 + r/n)^(nt)
- A = Final amount
- P = Principal
- r = Annual interest rate
- n = Compounding frequency
- t = Time in years
Example: $10,000 at 7% for 30 years
| Compounding | Final Amount | |-------------|--------------| | Annually | $76,123 | | Monthly | $81,165 | | Daily | $81,662 |
The Rule of 72
Years to double = 72 / Interest Rate
At 8%, your money doubles in ~9 years.
