How to Use the Interest Calculator AMEX
This calculator helps you to compute the final amount and total interest earned on a principal amount after a certain period of time, given an annual interest rate and a compounding frequency.
Steps to Use:
- Enter the principal amount (the initial amount of money).
- Enter the annual interest rate (in percentage).
- Enter the time (in years) for which the money is invested or borrowed.
- Select the compounding frequency from the dropdown menu.
- Click on “Calculate” to get the results.
How It Calculates:
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 interest is compounded per year.
- t is the time the money is invested for in years.
- A is the amount on the principal plus interest.
The total interest earned is determined by subtracting the principal amount from the financial amount.
Limitations:
This calculator does not account for the effects of taxes, fees, or other deductions. It assumes that the interest rate and compounding frequency are consistent throughout the period.
