Interest Calculator Judgment – Accurate Interest Calculation

Use this interest calculator to accurately determine how much interest you will earn over a specific period given your principal, rate, and time.

How to Use the Interest Calculator

Enter the principal amount in dollars (e.g., 1000). The principal is the initial amount of money invested or loaned.

Enter the annual interest rate as a percentage (e.g., 5 for 5%). The interest rate is the percentage of the principal earned or paid over a year.

Enter the number of years the money will be invested or borrowed for.

Select the compounding frequency (e.g., annual, semiannual, quarterly, monthly, daily).

Click the “Calculate” button to calculate the accrued amount and total interest earned or paid.

The result will show the principal amount, rate, years, frequency, accrued amount, and total interest in a table format.

How It Calculates the Results

The calculator uses the following formula for compound interest:

A = P (1 + r/n)^(nt)

Where:

A is the accrued amount (principal + interest)
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

The interest is calculated as the difference between the accrued amount and the principal amount.

Limitations

This calculator assumes that the interest rate does not change over the life of the investment or loan.

It does not account for taxes, fees, or other charges that may be associated with the investment or loan.

The calculator also assumes that all inputs are valid and does minimal validation of the inputs provided.
