The calculator will display your monthly payment, total interest paid over the life of the loan, and the net cost of financing your vehicle.
Formula Explained
The auto loan calculator uses the standard loan payment formula to calculate your monthly payments:
Loan Payment Formula
M = P [ i(1 + i)n ] / [ (1 + i)n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years multiplied by 12)
This formula calculates the fixed monthly payment required to pay off a loan with a fixed interest rate over a specified period.
Worked Example
Let's walk through an example to see how the calculator works. Suppose you're financing a $25,000 vehicle with a 4.5% annual interest rate over 5 years (60 months).
- Loan amount (P) = $25,000
- Annual interest rate = 4.5% or 0.045
- Monthly interest rate (i) = 0.045 / 12 ≈ 0.00375
- Loan term in months (n) = 5 × 12 = 60
Plugging these values into the formula:
Calculation
M = 25000 [ 0.00375(1 + 0.00375)60 ] / [ (1 + 0.00375)60 - 1 ]
M ≈ $454.23 per month
Total interest paid over 5 years would be approximately $3,229.80, and the net cost of financing would be $28,229.80.
