Buying a car in New Mexico
Every figure below is sourced to New Mexico’s own revenue or motor vehicle publications and dated. Estimates only.
Auto loan calculator
The real out-the-door number — including whether your state credits your trade-in against the sales tax.
Auto lease calculator
Money factor, residual, and the payment — taxed by your state's actual method, since some states tax a lease's full value upfront instead of each payment.
Loan payoff calculator
What paying extra actually saves you — in interest and in months — on a car loan, a personal loan, or anything else that amortizes.
0% APR vs. cash rebate
Which dealer offer actually costs less over the life of the loan, and the rate at which they tie.
Personal loan calculator
Payment, total interest, and the effective APR once an origination fee is deducted from what actually reaches your account.
Debt consolidation calculator
Whether one loan actually beats paying your existing debts off as they are — measured against the best you could do without consolidating.
Auto refinance calculator
Whether refinancing your car loan is worth it — including whether a lower payment is being bought with a longer term on a depreciating asset.
Lease vs. buy a car
The same car both ways over the same months, with the resale value credited to the buyer — the part most comparisons leave out.

Local tax in New Mexico
New Mexico does not apply its gross receipts tax to a vehicle purchase. A separate Motor Vehicle Excise Tax of 4% applies instead, due when the buyer applies for a certificate of title and collected by MVD or by the dealer on MVD's behalf. There is no municipal or county add-on. For non-dealer sales, if the declared price is below 80% of the N.A.D.A. average trade-in or wholesale value, the N.A.D.A. value is substituted. A 50% penalty for titling more than 90 days late raises the effective rate to 6%.
