About this tool
Enter a starting amount, an annual interest rate, a number of years and how often interest is compounded. The calculator uses the standard formula A = P x (1 + r/n)^(n x t), where P is the principal, r is the annual rate as a decimal, n is compounding periods per year and t is years. It shows the final amount and the interest earned. Compounding options are annual, semi-annual, quarterly, monthly (the default) and daily (365). It does not include regular deposits, fees, taxes or inflation, so the output is a general estimate and not financial advice. Calculations happen in your browser.
How to use it
- Enter the starting amount (principal).
- Enter the annual rate as a percentage, such as 5.
