📊 Example Calculation
Let’s assume the following:
- Car Price: $28,000
- Down Payment: $3,000
- Trade-In Value: $2,000
- Loan Term: 60 months
- APR: 6%
- Sales Tax: 8%
Step 1: Calculate taxable price
Vehicle price = $28,000
Tax = $2,240
Total = $30,240
Step 2: Subtract down payment and trade-in
$30,240 – $3,000 – $2,000 = $25,240 loan amount
Step 3: Estimate monthly payment
At 6% APR for 60 months:
- Monthly Payment: ≈ $487
- Total Interest: ≈ $3,980
- Total Cost: ≈ $32,220
The calculator makes all these estimates automatically.

This reduces your principal and interest.

A higher score means a lower APR.
