How to Use This Calculator

Using our 84 month auto loan rates calculator is simple:

The calculator will show you:

Monthly payment amount
Total interest paid over the loan term
Total amount paid (principal + interest)
A breakdown of how much goes toward principal vs. interest each month

Formula Used

The calculator uses the standard auto 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 (84 months)

Total interest is calculated by multiplying the monthly payment by 84 and subtracting the principal amount.

Worked Example

Let's calculate a $25,000 loan with a 4.5% interest rate and $5,000 down payment:

Principal = $25,000 - $5,000 = $20,000
Monthly rate = 4.5% / 12 = 0.375% or 0.00375
Monthly payment = $20,000 × (0.00375(1 + 0.00375)^84) / ((1 + 0.00375)^84 - 1) ≈ $328.50
Total interest = ($328.50 × 84) - $20,000 ≈ $1,350.80

This means you'd pay approximately $328.50 per month for 7 years, with $1,350.80 going to interest.

Interpreting Results

When using this calculator, consider these key points:

Lower interest rates save you money over the life of the loan
A larger down payment reduces your principal and monthly payments
The chart shows how much of each payment goes to principal vs. interest
Compare different loan amounts and rates to find the best deal

Remember that auto loans typically have good rates and flexible terms, but always shop around and compare offers from different lenders.
