Example Calculation

Let’s see an example to understand how the Carmax Finance Calculator works:

Car Price: $25,000
Down Payment: $5,000
Loan Term: 48 months
Interest Rate: 5%

Step 1: Calculate principal loan amount
Principal = Car Price − Down Payment = 25,000 − 5,000 = $20,000

Step 2: Monthly interest rate
Monthly Rate = Annual Rate ÷ 12 ÷ 100 = 5 ÷ 12 ÷ 100 = 0.004167

Step 3: Monthly payment
Monthly Payment = Principal × [r(1+r)^n / ((1+r)^n − 1)]
= 20,000 × [0.004167 × (1+0.004167)^48 / ((1+0.004167)^48 − 1)] ≈ $460.41

Step 4: Total payment
Total Payment = Monthly Payment × Months = 460.41 × 48 ≈ $22,099.68

Step 5: Total interest
Total Interest = Total Payment − Principal = 22,099.68 − 20,000 ≈ $2,099.68

With this calculator, you instantly know your monthly payment is $460.41 and the total interest paid over 48 months is $2,099.68.
