This tool calculates the interest earned on your investment over a specified period, providing detailed results for informed decision-making.
How to Use the Interest Calculator
To use this interest calculator, enter the following values:
- Principal Amount: The initial amount of money that you invested or borrowed.
- Annual Interest Rate (%): The yearly interest rate expressed as a percentage.
- Times Compounded Per Year: The number of times that interest is compounded per year.
- Years: The total number of years the money is invested or borrowed for.
After entering the values, click on the “Calculate” button to see the results. The results will display the final amount accumulated and the interest earned over the specified period.
Calculation Method
The calculator uses the formula for compound interest:
A = P (1 + r/n)^(nt)
- P: Principal amount
- r: Annual interest rate (decimal)
- n: Number of times interest is compounded per year
- t: Time the money is invested or borrowed for, in years
The final amount (A) is calculated and the interest earned is derived by subtracting the principal amount.
Limitations
This calculator assumes that interest is compounded at regular intervals and does not account for variations such as fees, taxes, or attempts to deposit or withdraw money during the investment period. Results should be used for indicative purposes only, and financial decisions should be based on discussions with a professional financial advisor.
