True Cost to Own a Car in Massachusetts
What a car costs to own in Massachusetts depends on more than the sticker price — Massachusetts's sales tax, registration fees and insurance rates all feed into the five-year total. This calculator starts from Massachusetts figures and shows the real cost per year, per month and per mile.
Adjust the price, your mileage and the loan terms to match your situation. Depreciation is usually the largest cost and is estimated from national averages; the Massachusetts-specific taxes, fees and insurance are shown with their sources below.

Calculation Formulas
The six ownership buckets summed over the years you keep the car. Depreciation is the purchase price minus the estimated resale value at the end of the period.
Resale value is modeled with an elevated first-year drop (default 20%) and a steady decline after, calibrated to a 5-year loss (default 45%).
Example:
A $40,000 car retaining 55% after 5 years is worth about $22,000, so depreciation ≈ $18,000 — usually the single largest cost.
P is the amount financed, r is the monthly rate (APR ÷ 12), and n is the term in months. This is the standard fixed-rate loan formula U.S. lenders use.
Energy cost scales with how much you drive, your efficiency, and local fuel price.

Frequently Asked Questions
What is included in the true cost to own a car?
Six buckets: depreciation (the value the car loses), loan interest, fuel or electricity, insurance, maintenance and repairs, and taxes and fees. Depreciation is usually the largest and the one buyers overlook.
Why is depreciation the biggest cost?
A new car typically loses around 20% of its value in the first year and close to half within five years. You never get a bill for it, but it is real money — the gap between what you paid and what the car is worth when you sell.
How much does the average car cost per year to own?
AAA has reported an average above $12,000 a year to own and operate a new vehicle driven 15,000 miles. Your number depends heavily on the car, your mileage, and your insurance and fuel costs.
Does a cheaper car always cost less to own?
No. A low sticker price can hide fast depreciation, poor fuel economy, or high insurance and repair costs. Comparing the five-year total cost — and the cost per mile — is the only way to know.
