Formula Used
The monthly payment for an auto loan is calculated using the standard loan payment formula:
Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal loan amount (loan amount - down payment)
- r = Monthly interest rate (annual rate / 12)
- n = Number of payments (75 months)
Total interest paid is calculated by multiplying the monthly payment by 75 and subtracting the principal loan amount.
Worked Example
Let's calculate a 75 month auto loan with these parameters:
- Loan amount: $25,000
- Interest rate: 5.5% APR
- Down payment: $2,500
The principal loan amount is $25,000 - $2,500 = $22,500.
The monthly interest rate is 5.5% / 12 = 0.4583%.
Using the formula:
Monthly Payment = $22,500 × (0.004583(1 + 0.004583)^75) / ((1 + 0.004583)^75 - 1)
Monthly Payment ≈ $378.25
Total interest paid over 75 months would be $378.25 × 75 - $22,500 ≈ $1,278.75.
This example shows that with a $25,000 loan at 5.5% APR over 75 months, you would pay approximately $378.25 per month with about $1,279 in total interest.
