This tool allows you to explore interest growth over time. You can either project your future earnings based on a starting amount, or work backwards to calculate the upfront investment needed to achieve a specific target.
Enter your starting principal and annual interest rate to find out how much interest you will earn per year, month, week, and day.
* Calculations are based on a Simple Interest (Flat Rate) method, where interest is not compounded over time. Time periods are calculated as exact fractions of a standard year: months are exactly 1/12 of the annual amount, weeks are 1/52, and days are 1/365.
