Formula Used

The calculator uses the standard loan amortization formula to calculate monthly payments:

The total cost of the loan is calculated by multiplying the monthly payment by the number of payments.

Worked Example

Let's calculate a $20,000 loan with a 5% annual interest rate over 5 years (60 months):

1. Convert annual interest rate to monthly: 5% ÷ 12 = 0.4167% or 0.004167
2. Plug values into the formula:

   M = 20,000 [0.004167(1 + 0.004167)^60] / [(1 + 0.004167)^60 - 1]

3. Calculate the monthly payment: $362.10
4. Total cost of the loan: $362.10 × 60 = $21,726.00

This example shows that the total cost of borrowing $20,000 over 5 years at 5% interest would be $21,726, including $1,726 in interest.

Interpreting Results

When you use the calculator, you'll see several key results:

• Monthly Payment: The amount you'll pay each month.
• Total Interest: The total interest paid over the life of the loan.
• Total Cost: The sum of the principal and total interest.

Compare these results with other loan options to make an informed decision. Remember that actual loan terms may vary based on your creditworthiness and other factors.
