How the Calculation Works
Who Should Use This Tool
Built for shoppers comparing dealer financing against bank and credit-union offers, and for owners weighing an early payoff or a refinance.
Important Considerations
Remember that actual terms, rates, and costs will vary by lender, your credit score, and current market conditions. These calculators provide educational estimates only and do not constitute professional financial advice. Always compare multiple offers and consult a financial professional before making decisions.
How the math works
Monthly payment uses the standard amortisation formula P x r(1+r)^n / ((1+r)^n - 1), where P is the amount financed, r the monthly rate (APR divided by 12) and n the number of monthly payments. Amount financed = price + tax and fees - down payment - trade-in equity.
How to use this calculator
- Enter the negotiated price, not the advertised sticker price: the out-the-door amount is what actually gets financed.
- Add your down payment and any trade-in equity, since both cut the amount financed dollar for dollar.
- Use the APR from a real pre-approval rather than a dealer's headline 'as low as' rate.
- Select the term you are genuinely being offered; longer terms shrink the payment but raise total interest.
- Read the total interest line before signing, because the term usually moves it more than the rate does.
- Sanity-check the answer against the 20/4/10 rule: 20% down, a four-year term, and total car costs under 10% of gross monthly income.
