Formula Used
Auto Loan Payment Formula
The monthly payment (PMT) for an auto loan is calculated using the formula:
PMT = 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)
Total interest paid = (Number of payments × PMT) - Principal
The calculator applies this formula to provide your estimated monthly payment and financial breakdown.
Worked Example
Let's calculate a $25,000 auto loan with a 4.5% annual interest rate over 5 years:
- Monthly interest rate = 4.5% ÷ 12 = 0.375% or 0.00375
- Number of payments = 5 × 12 = 60
- PMT = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)
- PMT ≈ $452.38 per month
- Total paid = $452.38 × 60 ≈ $27,142.80
- Total interest = $27,142.80 - $25,000 = $2,142.80
This example shows you would pay approximately $452.38 per month with $2,142.80 in total interest over the loan term.
