Dealer Finance vs a Bank Loan: Which Is Cheaper?
Finance at the forecourt or borrow from a bank — compared on cost and convenience.
A bank loan is often cheaper and lets you own the car outright; dealer finance is more convenient and can win when there's a genuine 0% or manufacturer offer.
A bank or personal loan is often cheaper in total and makes the car yours from day one, while dealer finance is more convenient and sometimes carries a 0% offer. A loan you arrange; dealer finance is sorted on the spot.
Compare on the true cost, not the convenience. The headline monthly at the dealer can hide a higher rate than your bank would charge.
Dealer finance vs a bank loan at a glance
A bank loan buys the car outright and is often cheaper; dealer finance is quicker but the rate can be higher. Manufacturer 0% deals are the exception.
With a bank loan you walk in as a cash buyer, which can sharpen your price. Dealer finance is convenient and occasionally unbeatable on a manufacturer 0% deal, but the standard rate may be higher than your bank's — so always compare the APR.
| Dealer finance | Bank / personal loan | |
|---|---|---|
| Typical rate | Varies, can be higher | Often lower |
| Own the car? | Depends (PCP/HP) | From day one |
| Convenience | Sorted on the spot | Apply separately |
| Bargaining power | Tied to one dealer | Cash buyer at the dealer |
| Best for | 0%/manufacturer deals | Lowest rate, owning outright |
Worked example: dealer finance vs a bank loan
On the same £20,000 car, a bank loan at a lower APR can save hundreds in interest versus a dealer rate — unless the dealer offers a genuine 0%.
The only way to know is to compare both on APR. Get a loan quote first, then ask the dealer to beat it. Turn any quote into a true rate on the APR and true-cost calculator, and work the loan side on the car loan calculator.
Worked example
Who each option suits
Use a bank loan for the lowest rate and outright ownership; take dealer finance for convenience or a real 0% deal.
- Bank / personal loan if: you want the lowest rate, to own the car from day one, and the bargaining power of a cash buyer.
- Dealer finance if: there's a genuine 0% or manufacturer offer, you value sorting it on the spot, or your bank can't beat the rate.
- Always get a loan quote before you visit — it's your benchmark and your bargaining chip.
Work out your own numbers
Compare both quotes on APR and total interest before you sign anything.
Use the car loan calculator for the bank side and the APR and true-cost calculator to check the dealer's deal. See how loans, PCP and HP compare on the car finance calculator.
