This tool calculates the difference in interest between two loan options, helping you compare which one saves you more money.
How to Use the Interest Difference Calculator
This calculator allows you to compare the interest earned on the same principal amount at two different interest rates over a specified period of time. To use the calculator, follow these steps:
- Enter the principal amount, which is the initial amount of money.
- Enter the first interest rate (Rate 1) in percentage per year.
- Enter the second interest rate (Rate 2) in percentage per year.
- Enter the time period in years.
- Click the “Calculate” button to see the results.
The calculator will display the interest earned at each rate and the difference between these two amounts.
How the Calculator Calculates the Results
The calculator uses the following formula to calculate the interest:
- Interest Amount at Rate 1 = Principal x (Rate 1 / 100) x Time
- Interest Amount at Rate 2 = Principal x (Rate 2 / 100) x Time
The difference in interest is the absolute difference between the interest amounts calculated at the two rates.
Limitations
The calculator assumes the interest rate is applied annually and the time period is in years. Make sure all inputs are positive and valid. The principal amount should be greater than zero, the interest rates should be non-negative, and the time period should be greater than zero.
