About the Compound Interest Calculator
Calculates the total value of an investment using the compound interest formula.
How the Calculation Works
A = P × (1 + r/n)^(n×t), where P is the principal, r is the annual rate as a decimal, n is the number of compounding periods per year, and t is the term in years.
Use the result as a planning estimate. Check the inputs and confirm current rates, rules, or official records before making financial or employment decisions.
