Introduction

Automakers often offer either a cash rebate or a promotional APR—not both. This calculator runs parallel scenarios with the same vehicle price, down payment, taxes, and fees to show which deal costs less over the loan term.

Rebate vs Low APR

Automakers often offer either a cash rebate or a promotional APR—not both. This calculator runs parallel scenarios with the same vehicle price, down payment, taxes, and fees to show which deal costs less over the loan term.

How Rebates Work

A rebate reduces the amount financed at the standard APR. Even with a higher rate, a large rebate sometimes wins on total interest and overall cost—especially on shorter terms.

Promotional Financing

0% or low APR deals may require top-tier credit and shorter terms. If you do not qualify, the standard rate scenario is the fair comparison.

Total Cost Focus

Monthly payment alone misleads. Compare total interest, upfront cash, and lifetime cost. Read auto financing tips before signing.

How It Works

  1. Enter your amounts, rates, and term in the form. Use the same units shown in the labels (dollars, years, percent).
  2. Click Calculate to run the Cash Back or Low Interest Calculator engine. Invalid or empty required fields show a clear error message.
  3. Review the summary cards for the key outputs. Expand schedules or tables when available for period-by-period detail.
  4. Copy, print, or share your scenario link. Reset the form anytime to start a fresh comparison.

Formula

Scenario A finances (price - rebate - down payment + adjustments) at the standard APR. Scenario B finances (price - down payment + adjustments) at the promotional APR. The better offer has the lower total of payments plus upfront cash.
