Outsmart the Lot

Car Shopper's Toolkit

Don't walk into the dealership empty-handed. These free calculators help you check a written out-the-door price—the vehicle transaction total before financing costs—plus loan costs, trade-in value, and more.

Check a written quote

Quote Check

Copy the dollar amounts from a written quote. This check adds them and compares the optional written total; it does not estimate market value or judge the purchase.

Arithmetic check only. The entered amounts may still be incomplete or inaccurate; verify the buyer's order before signing.

NMVTIS History

Know What the Report Covers

VINsmart is currently listed by the U.S. Department of Justice as an approved public NMVTIS data provider. An NMVTIS report is one limited history check, not a verdict on the vehicle.

Use the five federal indicators shown here for the NMVTIS check. Run recalls through NHTSA, and verify condition and repair needs with an independent inspection.

Official NMVTIS scope

Five indicators to check

  • Title state and last title date
  • Brand history
  • Latest reported odometer reading
  • Total-loss history
  • Salvage history

NMVTIS does not replace the separate NHTSA recall lookup or an independent inspection.

Official NMVTIS Sources

Coverage can vary with what participating sources have reported. Always combine a history check with the paperwork and an independent inspection.

Financial Reality Check

Unclear or incomplete math can hide costs. Use these calculators to verify the written numbers.

Payoff / Vehicle Value Check

Compare a current lender payoff with an entered vehicle-value estimate. Payoff minus vehicle value is the negative-equity calculation.

Use a current payoff statement, not only the last account balance.

Use a dated offer or estimate that reflects mileage and condition.

Values can change with payoff timing, mileage, condition, and the specific offer. Recheck both numbers for the transaction date.

Trade-In vs. Private Sale

Compare the entered trade and private-sale amounts before lender payoff. Supply any verified trade tax credit as a dollar amount and include the costs you expect for a private sale.

Enter 0 if you have confirmed there is no trade tax credit or no private-sale cost. This tool does not infer eligibility or an amount from your state.

This comparison does not subtract a lender payoff. For the same vehicle, the same payoff applies to either path, so it does not change the displayed difference; subtract it from either amount to estimate cash remaining.

Loan Term Comparison

Compare fixed monthly-payment estimates, total interest, and total paid at the same entered principal and annual contract interest rate. No term is selected for you.

APR is for comparing offers and may include mandatory fees this payment estimate does not model. Enter the annual contract interest rate; zero is supported.

Planning Tools

Make the written arithmetic and estimates visible before you sign.

Out-the-Door Line-Item Check

Add the dollar amounts from a written buyer's order. Enter the quoted tax amount directly; this tool does not assume a taxable base or state rule.

Selling price shown before the other listed amounts.

Products or services listed by the dealer; enter 0 if none.

Dealer or processing fees shown on the order.

Use the tax dollars on the written quote—not an estimated rate.

Combine the government fees shown on the order.

Dollar credits subtracted on the order; enter 0 if none.

The written trade allowance applied after the out-the-door total; enter 0 if none.

The written payoff on the trade added after its allowance; enter 0 if none.

Lease-Maturity Lease / Buy Comparison

Compare entered lease and purchase net costs at the same scheduled lease-maturity point.

Both scenarios end here at lease maturity. The number of scheduled lease payments equals this term.

Lease inputs

Start with the dealer's total due at signing, then subtract any first monthly lease payment included in that figure and any refundable security deposit. Enter the remaining upfront fees or down payment.

Include disposition, excess-mileage, or wear charges you reasonably expect at the scheduled lease end.

Buy inputs

Count scheduled purchase payments made by lease maturity; this cannot exceed the comparison point.

Estimate the loan balance at the scheduled lease-maturity comparison point.

Estimate the purchased vehicle's value at that same comparison point.

Enter 0 for a required cost, balance, or purchase-payment count only when none applies by the comparison point.

Use the VIN lookup to check for unrepaired safety recalls. NHTSA notes that some very recent recalls, recalls more than 15 years old, and notices from certain small manufacturers may not appear; ask the manufacturer or dealer about remedy details and parts availability.
