About Compound Interest Calculator
Compound interest calculates earnings on both the original principal and previously earned interest. It is widely used in savings, investments and financial planning. This calculator helps you estimate how money grows over time with compounding.
The formula used is A = P (1 + r/n)^(n t), where P is principal, r is annual rate, n is compounding frequency and t is time in years. The difference between maturity amount and principal is the compound interest earned.
