This tool calculates your interest earnings from an annual percentage rate (APR).
Interest Calculator Instructions
This interest calculator helps you calculate the accrued interest over a specified time period based on the Annual Percentage Rate (APR) and number of compounds per year.
How to Use the Calculator
- Enter the Principal Amount in dollars.
- Enter the Annual Percentage Rate expressed as a percentage (%).
- Enter the Time Period in years.
- Enter the Compounds per Year.
- Click the “Calculate” button to see the results.
Calculation Explanation
The calculator uses the formula for compound interest:
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 the interest is compounded per year.
- t is the number of years.
The final accrued amount (A) is calculated and the interest accrued is derived by subtracting the principal amount from the accrued amount.
Limitations
- The calculator assumes a fixed interest rate over the time period.
- It does not account for changes in the principal amount due to withdrawals or additional deposits.
- It assumes that the compounding frequency does not change over the time period.
