Owning a new car in Connecticut costs about $68,605 over five years — $8,034 more than the US average — driven mainly by insurance running +33% against the national average. That makes Connecticut the 2nd most expensive of 51 US jurisdictions to run a car.
What Connecticut actually changes
Of the $68,605 five-year average, about $35,619 is state-controlled — insurance, fuel or charging, registration and service labour. Across the 51 US jurisdictions that portion ranges from $22,139 in Idaho to $37,173 in Nevada, which is where essentially the entire gap between the cheapest and most expensive states comes from.
The single biggest ownership cost — depreciation — does not vary by state. A car loses the same share of its value in Connecticut as anywhere else, so moving state changes the running bill, not the whole picture. That is also why the ten cheapest cars to own look broadly similar in every state: depreciation anchors the ordering.
| Cost | Connecticut vs national | Why |
|---|---|---|
| Fuel & charging | +$1,019 | Gas $4.63/gal (national $4.49), electricity 30¢/kWh (national 18¢) |
| Insurance | +$4,420 | Full-coverage premiums run +33% vs the national average |
| Registration | +$2,596 | Charged on vehicle value, no EV surcharge |
| Depreciation | $0 | Does not vary by state — the same car loses the same value anywhere |
Car insurance in Connecticut
Full-coverage car insurance in Connecticut runs +33% against the national average — 7th most expensive of 51 US jurisdictions. Across the 81 vehicles we track, that works out to about $3,563 a year for the average car, though the figure swings widely by vehicle.
These are state-average ratios, not quotes. They come from the mean of two independent published rate surveys — ValuePenguin (January 2026) and Insurify (July 2026) — because published tables disagree by more than most buyers expect: different driver profiles, coverage limits and carrier mixes. Averaging two sources rather than trusting one is deliberate. Last recalibrated 2026-07-24.
Vehicle registration in Connecticut
Connecticut ties annual registration to what the car is worth, so an expensive vehicle costs more every year, not just at purchase. On a $35,000 car the annual figure works out to roughly $605 — most expensive of 51 US jurisdictions.
| Component | Amount | Notes |
|---|---|---|
| Base fee | $80 | Fixed annual DMV/renewal portion |
| Value-based portion | $525 | 1.50% of vehicle value (5-year average effective rate — year-one is higher and falls as the car depreciates) |
| Gas or hybrid total | $605 | What a combustion car pays each year |
| Electric total | $605 | Connecticut levies no EV surcharge |
Modelled from published DMV fee schedules, the NCSL state EV-fee tracker and Tax Foundation data (2026-05-26). These are five-year-average estimates, not quotes — county and municipal add-ons vary within a state, particularly where the recurring charge is collected as a local personal-property tax.
Does an EV still make sense in Connecticut?
On energy alone, yes. Charging the average electric vehicle at home in Connecticut costs about 9.3¢ a mile, against 19.1¢ to fuel the average gas car — a saving of roughly $1,467 a year at 15,000 miles, with no EV surcharge to offset it.
Energy is not the whole story, though — and the ranking below shows why. The best-placed electric vehicle in Connecticut is the 2027 Chevrolet Bolt, at 7th cheapest to own overall. One electric vehicle reaches this state's ten cheapest cars to own. That position moves between states — from 2nd in Washington, where electricity is cheapest relative to gas, to 11th in Maryland and Rhode Island — because the charging saving has to overcome depreciation, which does not vary by state.
Assumes home charging at the state residential rate, no public fast-charging premium, and fleet-average efficiency across the electric and gas vehicles we track. Gas prices are AAA state averages (2026-05-25); electricity is EIA residential (2026-05-25).

All 81 vehicles at Connecticut prices
The complete table, cheapest to most expensive in Connecticut. The final column is the difference against the same vehicle costed at national-average prices — so you can see exactly what the state adds or saves on each car.
Each vehicle is priced at its representative trim — the same basis as our cheapest cars to own ranking and the Ownership Cost Index, so the figures agree across the site. Five-year totals include depreciation, fuel or charging, insurance, maintenance, tyres, registration and loan interest. How these numbers are built.
Where these numbers come from
Four independent per-state data sources drive everything on this page, each covering all 51 US jurisdictions. Nothing here is a national figure with a state name attached.
- Insurance — the mean of two published full-coverage rate surveys, ValuePenguin and Insurify (2026-07-24).
- Gas — AAA state averages (2026-05-25).
- Electricity — EIA Electric Power Monthly, residential rates (2026-05-25).
- Registration — state DMV fee schedules, the NCSL EV-fee tracker and Tax Foundation data (2026-05-26).
Two things we deliberately do not claim. Service and repair labour rates also vary by state, but no published survey covers all 51 jurisdictions the way premium data does, so we model it only for the largest markets and hold the rest at the national rate — rather than print a placeholder as though it were a finding. And depreciation, the largest cost of all, is drawn from resale-value data that is national: it does not vary by state, and this page does not pretend otherwise.
Frequently asked questions
- How much does it cost to own a car in Connecticut?
- Across the 81 new vehicles MotiveGrid tracks, the average car costs $68,605 to own over five years in Connecticut — about $1,143 a month, including depreciation, fuel or charging, insurance, maintenance, tyres, registration and loan interest. That is $8,034 more than the US average, making Connecticut the 2nd most expensive of 51 US jurisdictions to run a car. Of that total, roughly $35,619 is the portion Connecticut actually controls; depreciation, the largest single cost, does not vary by state.
- Is car insurance expensive in Connecticut?
- Full-coverage car insurance in Connecticut runs +33% against the national average, which makes it the 7th most expensive of 51 US jurisdictions. For the average vehicle we track that works out to roughly $3,563 a year. These are state averages drawn from two published rate surveys, not quotes — your own premium depends on your car, driving record, coverage level and ZIP code.
- How much is car registration in Connecticut?
- Connecticut charges annual vehicle registration based on the car's value rather than a flat fee, so a more expensive car costs more every year. On a $35,000 vehicle the annual cost works out to about $605 — a $80 base fee plus roughly 1.50% of the vehicle's value, averaged over a five-year hold as the car depreciates. Connecticut adds no separate EV surcharge.
- Is an electric car cheaper to run in Connecticut?
- On energy, yes. Charging the average electric vehicle at home in Connecticut costs about 9.3¢ a mile at the state's residential electricity rate, against 19.1¢ a mile to fuel the average gas car — a saving of roughly $1,467 a year at 15,000 miles, with no EV surcharge to offset it. Energy is only part of the picture, though: the best-placed electric vehicle in Connecticut ranks 7th cheapest to own overall, because depreciation and purchase price still dominate the five-year total.
- What is the cheapest car to own in Connecticut?
- The 2026 Toyota Corolla is the cheapest of the 81 vehicles we track to own in Connecticut, at $38,798 over five years — about $647 a month all-in. The most expensive is the 2026 Lucid Gravity at $118,205. Both figures are computed at Connecticut's own insurance, registration, fuel and electricity costs, at each model's representative trim and 15,000 miles a year.
- Does moving to another state actually lower what my car costs?
- It changes the running costs, not the whole bill. In Connecticut roughly $35,619 of the $68,605 five-year average is state-controlled — insurance, fuel or charging, registration and service labour. Depreciation, usually the single largest cost of owning a new car, is set by the national resale market and does not vary by state. So the state you register in moves the part you pay monthly, while the largest cost follows the car wherever it goes.
