About the Cash Back or Low Interest Calculator
Car dealers routinely offer a choice between a cash rebate (with standard financing) or a below-market low interest rate (with no rebate), and it's genuinely not obvious from the sticker numbers alone which one actually costs less — the answer depends on the vehicle price, the rate gap between the two offers, and the loan term, not just which discount sounds bigger.
This calculator runs the total cost of both financing paths side by side — the rebate reducing what you finance versus the low rate reducing what that financing costs — so the comparison is a real total-dollar number instead of a guess about which incentive is 'worth more.'
It's aimed squarely at car buyers staring at exactly this choice on a purchase agreement, before signing either option.

Frequently asked questions
Is the cash rebate or the low interest rate usually the better deal?
It depends on the numbers — a bigger rate gap between the two offers tends to favor the low-rate option, while a shorter loan term (which limits how much the rate difference can compound) tends to favor the cash rebate. There's no universal answer; that's exactly what this calculator compares.
Does the loan term length change which option is cheaper?
Yes, significantly — a longer term gives the low interest rate more time to compound its advantage, while a shorter term gives interest less time to matter at all, which can tip the comparison toward the cash rebate instead.
Can I negotiate the vehicle price down and still take the low interest rate?
Sometimes, though dealers often tie the low rate offer to the listed price and treat any price negotiation as forfeiting it — always confirm directly with the dealer which parts of an offer are actually negotiable together.
Are there other costs this comparison doesn't include?
Yes — this compares only the financing math (price, rebate and rate) over the loan term. Sales tax, registration fees, and any dealer add-ons aren't included and can shift the real total cost of either path.
