Massachusetts car loan calculator

Massachusetts charges a 6.25% state sales tax on most vehicle purchases. Massachusetts charges one statewide rate, with no added local sales tax on vehicles. The state figure is the main tax on most Massachusetts vehicle purchases, but registration, title, and dealer fees are separate.

Example: on a $36,000 vehicle with $5,000 down and a $2,500 trade-in, the state-level tax figure above adds about $2,250. Financing $30,750 at 7.25% APR for 60 months works out to roughly $613 per month and $6,001 in total interest. Change any field in the calculator above to match your deal.

State-level figures reviewed October 2026. Rates change and local rules differ, so treat this as an estimate and confirm with the Massachusetts revenue department or DMV. Compare every state on the car tax by state page.

Car buyers in Massachusetts should look beyond the advertised vehicle price. Tax, lender APR, dealer documentation charges, title costs, insurance, and registration can all affect the final monthly payment. Ask for an itemized out-the-door price so you know exactly what is being financed.

Use a conservative APR until you have a preapproval. Credit unions, banks, captive lenders, and dealer finance offices can quote different terms for the same vehicle. Comparing the total interest line helps you avoid choosing a loan that looks affordable only because the term is stretched too far.
