This tool will help you calculate the interest earned on your investment.
How to Use the Interest Calculator
To use this interest calculator, follow these steps:
- Enter the principal amount (initial amount of money).
- Input the annual interest rate (as a percentage, e.g., 5.5 for 5.5%).
- Specify how many times the interest is compounded annually (e.g., 12 for monthly compounding).
- Enter the number of years the money is invested or borrowed for.
- Click the “Calculate” button to see the results.
How It Calculates the Results
The calculator uses the formula for compound interest to compute the total amount and the interest earned:
A = P (1 + r/n)^(nt)
Where:
- P is the principal amount.
- r is the annual interest rate (decimal).
- n is the number of times interest is compounded per year.
- t is the time the money is invested or borrowed for in years.
- A is the amount of money accumulated after n years, including interest.
The interest earned is calculated as the total amount minus the principal.
Limitations
- The calculator assumes the rate of interest remains constant throughout the entire period.
- It does not account for taxes or fees that might be charged.
- Values should be realistic positive numbers to prevent miscalculations.
