The calculator will display your estimated monthly payment, total interest paid over the life of the loan, and a breakdown of principal and interest payments.
Formula Used
The auto loan payment is calculated using the standard loan payment formula:
Loan Payment Formula
Monthly Payment = P × (r(1 + r)n)/( (1 + r)n - 1)
Where:
- P = Principal loan amount
- r = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years × 12)
This formula accounts for both the principal and interest payments over the life of the loan, providing an accurate estimate of your monthly obligation.
Worked Example
Let's calculate a loan with the following details:
- Loan Amount: $25,000
- Annual Interest Rate: 5%
- Loan Term: 5 years
Using the formula:
Calculation Steps
1. Convert annual rate to monthly: 5% ÷ 12 = 0.4167% or 0.004167
2. Calculate number of payments: 5 years × 12 = 60 months
3. Plug values into formula: $25,000 × (0.004167(1 + 0.004167)60)/( (1 + 0.004167)60 - 1)
4. Result: $478.87 per month
This example shows that a $25,000 loan at 5% interest over 5 years would require monthly payments of approximately $478.87.
