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.
常见问题
Does it include inflation or taxes?
No. Results are before tax and in today's money terms. Use a lower rate to allow for inflation.
Is anything sent anywhere?
No. The calculation happens in your browser, and your numbers never leaves your device.
