About Compound Interest Calculator
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. This calculator shows your maturity value and total interest earned based on your compounding frequency.
Compound Interest Formula
Where P is principal, r is the annual interest rate (decimal), n is the compounding frequency per year, and t is time in years.
Benefits
- • Compare how compounding frequency changes your final returns.
- • Understand the difference between simple and compound growth over time.
Common mistakes
- • Assuming compounding frequency doesn't matter — more frequent compounding yields higher returns at the same nominal rate.
