Formula Used
Monthly Payment Formula
The calculator uses the standard auto loan payment formula:
M = P [ i(1 + i)n ] / [ (1 + i)n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount (loan amount - down payment)
- i = Monthly interest rate (annual rate / 12)
- n = Number of payments (72 months)
This formula accounts for the fact that each monthly payment includes both principal and interest, with the interest portion decreasing over time as the principal balance decreases.
Worked Example
Let's calculate a 6-year auto loan for $25,000 at 4.5% APR with a $5,000 down payment:
- Principal = $25,000 - $5,000 = $20,000
- Monthly interest rate = 4.5% / 12 = 0.375% or 0.00375
- Number of payments = 72
- Using the formula: M = $20,000 [ 0.00375(1 + 0.00375)72 ] / [ (1 + 0.00375)72 - 1 ]
- Calculating the components:
- (1 + 0.00375)72 ≈ 1.365
- Numerator ≈ $20,000 × 0.00375 × 1.365 ≈ $116.25
- Denominator ≈ 1.365 - 1 = 0.365
- M ≈ $116.25 / 0.365 ≈ $318.52
Your estimated monthly payment would be $318.52, with a total interest of $1,728.28 over 6 years.
| Loan Amount | Down Payment | Interest Rate | Monthly Payment | Total Interest |
|---|---|---|---|---|
| $25,000 | $5,000 | 4.5% | $318.52 | $1,728.28 |
