Dealer vs Bank Financing Guide
Compare dealer and outside auto financing including rebates and fees.
Build a baseline, conservative case, and alternative
The calculator organizes assumptions. It does not replace a contract, tax determination, recommendation, or current market quote.
Start with source figures
Compare both offers using the same price and down payment, including rebates lost, required fees, APR, term, payment, and total cost.
- Get written out-the-door pricing first.
- Ask whether a rebate depends on the lender.
- Compare total repayment, not only payment.
Run more than one scenario
Save the documented baseline, then change the assumption most likely to move. If a small change reverses the decision, gather better information or preserve more margin.
Verify before acting
Use the dealer vs bank financing calculator to create a comparable estimate, then reconcile important figures with the relevant statement, quote, contract, or official source.
