Car financing strategies: dealer vs. bank vs. credit union
Smart car financing means shopping the loan separately from the car — get pre-approved at a credit union or bank before visiting the dealer, compare APRs, and negotiate the price independent of the financing offer. Dealer financing often hides 1-3% markup on the rate. Larger down payments reduce monthly cost and avoid being upside-down (owing more than the car's worth).

Key takeaways
04 · ideas- Dealer APR markups of 1-3% over the buy rate are standard practice
- Credit unions average 1.5-2% lower rates than dealer financing
- Getting pre-approved before the dealership puts you in control
- 0% APR deals have a hidden cost: you lose the cash rebate
Car dealers make significant profit from financing — often more than from the car sale itself. Understanding this puts you in control.
How dealer financing works:- Dealer submits your application to multiple lenders
- Lenders respond with "buy rates" (the minimum rate they'll accept)
- Dealer marks up the rate by 1–3% and keeps the difference
- You're offered the marked-up rate as "the best we could do"
- 5% rate: $472/month, $3,307 total interest
- 7% rate: $495/month, $4,700 total interest
- Dealer profit from financing markup: $1,393
The fix: get pre-approved at a bank or credit union before the dealership. Then you have a comparison point and can negotiate financing the same way you negotiate price.
