How this calculator works
Promotional zero-percent financing and a rebate are often alternative offers. We compare zero interest on the full purchase balance against normal financing on a balance reduced by the rebate. Both use the same term, down payment and entered tax amount. The model treats the rebate as after-tax; tax treatment and eligibility must be confirmed with the dealer.
A worked example
On a $35,000 car with $5,000 down, a $3,000 rebate reduces principal immediately. Whether it beats 0% depends on the standard APR, financed taxes and loan term. A longer term gives the standard-rate loan more time to accrue interest.
The formula, in plain sight
0% principal = price + tax + fees + title − down payment. Rebate principal = 0% principal − rebate. Compare principal + interest for each option, adding the same down payment to each total.

Frequently asked questions about 0% apr vs. rebate
Is 0% APR better than a cash rebate?
Either offer may cost less, depending on the rebate amount, standard APR, loan term, vehicle price, fees, taxes, and your eligibility. Compare the total amount paid under both written offers, not just the monthly payment. This calculator models 0% financing against a standard-rate loan with a rebate applied after tax, so verify the actual tax treatment and offer rules.

Should I take 0% financing or a $3,000 rebate?
Compare the same vehicle and term using the offer’s actual APR and eligibility. For illustration, on a $30,000 balance over 60 months, 0% financing costs $30,000 before fees. A $3,000 rebate with a 7% loan on $27,000 would total about $32,077.94 in payments, so 0% costs less in that example. Real taxes and offer terms may change the result.

How much money can 0% APR financing save?
If you qualify and borrow the same principal for the same term, 0% APR avoids the scheduled interest that a positive-rate loan would charge. For example, $30,000 over 60 months at 7% APR produces about $5,642 in modeled interest, while the same balance at 0% has none. A rebate or different vehicle price can change which promotion costs less overall.

Can I get a cash rebate and 0% APR financing together?
Sometimes a promotion permits combining offers, but many programs present them as alternatives. Eligibility, vehicle, purchase date, lender, and other conditions can differ. Ask the dealer for the exact written terms for both choices, including the out-the-door price, and do not assume an advertised rebate and special APR can be stacked unless the offer documents say so.

Does 0% APR financing have hidden costs?
A 0% offer means no interest under the stated loan terms, but the vehicle price, fees, taxes, required down payment, and eligibility still matter. Some promotions may replace a rebate or apply only to certain buyers or models. Request the full written price and financing details, then compare them with other offers before signing.

How do I compare dealer financing promotions?
Ask for written versions of each offer with the selling price, incentives, APR, loan term, down payment, fees, eligibility conditions, and total amount paid. Compare the same vehicle and loan period, and check whether promotions can be combined. The calculator compares the entered 0% and rebate scenarios; use the dealer comparison calculator for other offers.
