đ What are Compound Interest?
đ° What are Compound Interest?
Compound interest is interest calculated on the initial principal plus any accumulated interest from previous periods. It's the famous "interest on interest" effect.
đ Compound Interest Formula
A = P Ã (1 + r)^n + C Ã ((1 + r)^n - 1) / r
- A = Final amount (Future Value)
- P = Initial principal
- r = Interest rate per period
- n = Number of periods
- C = Periodic contribution
đ¯ Rule of 72
Time to double = 72 / Interest Rate
Example: With a 10% annual rate, your money doubles in approximately 7.2 years.
