Formula Used
The calculator uses the following formula to calculate your monthly auto loan payment:
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 the interest on your loan balance each month, providing an accurate estimate of your monthly payment.
Worked Example
Let's calculate a monthly payment for a $20,000 loan at 4.5% annual interest for 5 years:
- Principal (P) = $20,000
- Annual interest rate = 4.5% or 0.045
- Monthly interest rate (r) = 0.045 / 12 ≈ 0.003792
- Number of payments (n) = 5 × 12 = 60
Monthly Payment = $20,000 × (0.003792(1 + 0.003792)^60) / ((1 + 0.003792)^60 - 1)
Monthly Payment ≈ $20,000 × (0.003792 × 1.2314) / (1.2314 - 1)
Monthly Payment ≈ $20,000 × 0.004706 / 0.2314
Monthly Payment ≈ $20,000 × 0.02034 ≈ $406.80
Your estimated monthly payment would be $406.80, with a total interest paid of $2,800 over the life of the loan.
