This tool will help you calculate the interest on your savings with detailed accuracy.
How to Use the Interest Calculator
This calculator helps you compute the final amount of an investment based on the principal, annual interest rate, number of years, and compounding frequency. To use it:
How It Calculates the Results
The calculator uses the formula for compound interest to compute the final amount and interest earned:
Formula: A = P * (1 + r/n)^(nt)
Where:
- A is the amount of money accumulated after n years, including interest.
- P is the principal amount (the initial sum of money).
- 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 for in years.
The calculator then subtracts the principal from the total amount to determine the interest earned.
Limitations
The calculator assumes that all interest rates are compounded regularly at the specified frequency and does not account for any additional contributions or withdrawals. The precision of calculations is rounded to two decimal places.
