Formula Used
The Carmax Auto Loan Calculator uses the standard auto loan payment formula:
Monthly 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 months)
This formula calculates the fixed monthly payment required to pay off the loan over the specified term, including interest.
Worked Example
Let's look at an example to see how the calculator works. Suppose you want to finance a car with these details:
- Loan amount: $25,000
- Interest rate: 5% APR
- Loan term: 60 months (5 years)
Using the formula:
Calculation Steps
1. Convert annual interest rate to monthly: 5% ÷ 12 = 0.4167% or 0.004167 in decimal
2. Calculate the monthly payment:
M = $25,000 [ 0.004167(1 + 0.004167)^60 ] / [ (1 + 0.004167)^60 - 1 ]
3. The calculation results in a monthly payment of approximately $454.23
After 60 months, you would have paid a total of $27,253.80, with $2,253.80 going to interest.
