Careful: Loan A has the smaller monthly payment but is the more expensive loan overall. A lower payment usually means a longer term, and a longer term means more months of interest.

How to compare loan offers without being fooled
- Normalise the amount. Comparing a $20,000 loan against a $22,000 loan tells you nothing about which lender is better.
- Put fees in writing. Origination fees, closing costs and prepayment penalties are all part of the price.
- Decide your constraint first. If cash flow is tight, the lower payment may genuinely be the right choice — just know what it costs.
- Set your car budget first. Before comparing auto financing offers, the car affordability calculator gives you a price ceiling from the payment you want.
- Check flexibility. A loan you're allowed to overpay without penalty is worth more than its APR suggests.
