At the dealership choosing between a cash rebate and 0% APR financing? Enter your deal to see which option costs you less over the full loan term — the math often surprises.

Quick answer: A cash rebate wins when upfront savings exceed the value of subsidized financing; low APR wins when interest savings are larger. Compare total loan cost, not just monthly payment.

Frequently Asked Questions

Everything you need to know.

Can I take both the rebate and the promotional rate?
Offer rules vary. Use the manufacturer or lender disclosure to confirm whether incentives may be combined and enter only the alternatives actually available to you.
What if I do not qualify for the promotional rate?
Use only a rate for which you received actual terms. Compare prequalified offers where available, and confirm whether the inquiry, vehicle, term, and credit tier change final pricing.
Does the loan term change which option wins?
Yes. A longer term increases the value of a lower rate, while a larger rebate reduces principal immediately. The result is specific to the values entered and excludes taxes and dealer fees unless they are already included in the vehicle price.

Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.

No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.

How fresh are the rates and offers shown?
Rate and offer data is reviewed on a recurring cadence and every offer module shows review context or links to the methodology and disclosure pages.
