How to use the compound interest calculator
- Enter a starting amount, what you add each month, the yearly rate and the number of years.
- Choose how often interest is compounded.
- Read the final balance and the year-by-year table, or download it.
How compounding works
Interest is added to the balance, and then it earns interest too. The formula for a single amount is A = P × (1 + r/n)^(n × t). With monthly additions, the calculator works month by month, using the monthly rate that matches your compounding.
