Frequently Asked Questions About Auto Loans
Understanding How Auto Loans Work
An auto loan is a secured loan where the vehicle serves as collateral. Our calculator helps you understand the full financial picture, showing exactly how much you'll pay over time.
Principal Amount
The amount borrowed:
Price - Down - Trade-In + Tax + Fees
Interest Rate (APR)
Annual borrowing cost. Depends on:
- Credit score
- Loan term
- Vehicle age
- Market conditions
Smart Auto Loan Strategies
1. Check Credit Score First
Check 3+ months before shopping. Every 50-point increase saves 1-2% on your rate.
2. Save Substantial Down Payment
Aim for 20% down on new, 10% on used. Lowers payment, reduces interest, prevents being underwater.
3. Get Pre-Approved from Multiple Lenders
Shop bank, credit union, and online within 14 days. Use pre-approvals to negotiate with dealer.
4. Choose Shortest Term Affordable
Stick to ≤60 months. If you can't afford a 60-month payment, the car is too expensive.
