This tool helps you calculate how much interest you’ll earn on your investment weekly.
Weekly Interest Calculator
This calculator helps you determine the amount of interest you can earn on a particular principal over a period of time on a weekly basis.
How it works
- Enter the principal amount in dollars.
- Input the annual interest rate in percentage.
- Provide the number of weeks you want to calculate the interest for.
- Enter the number of compounding periods per year (default is 52 for weekly).
- Click “Calculate”.
Explanation of the Calculation
The formula for compound interest used is: A = P(1 + r/n)^(nt), where:
- P is the principal amount
- r is the annual interest rate (decimal)

- t is the time the money is invested for in years
The calculator translates the given weeks into the appropriate number of periods and applies the compound interest formula to generate results.
