Buying a car in New Jersey
Every figure below is sourced to New Jersey’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.

New Jersey taxes a lease up front, not monthly
The whole sales tax on a lease is due at signing here rather than riding on each monthly payment. That is a different method, not a different rate, and it changes what you owe on the day — see the lease calculator above, which applies it.
Local tax in New Jersey
New Jersey has no general county or municipal sales tax, so 6.625% is the rate essentially statewide. Two narrow reduced-rate regimes exist — designated Urban Enterprise Zones, where qualifying in-zone retail sales are taxed at half the standard rate, and a similar arrangement in Salem County — but neither ordinarily applies to a vehicle purchase by a buyer registering elsewhere. Note that actual MVC title and registration fees are EXCLUDED from the taxable sales price while dealer documentary fees are INCLUDED.
