How this is calculated

The calculator above is pre-labeled with the 6 named fees Connecticut typically charges: Biennial registration fee; License plate fee; Title fee; Clean Air Act fee; Greenhouse gas reduction fee; Municipal property tax on vehicle (assessed annually by town). Connecticut charges a biennial registration plus several small environmental surcharges. Towns assess an annual property tax on vehicles separately at the municipal mill rate — this is the largest annual cost for most owners.

Default assumption: the pre-filled amounts represent a typical ~$30,000 midsize sedan, three years old, registered annually. Heavier vehicles, newer vehicles, higher-value vehicles, and electric / plug-in hybrids will see different amounts in most categories — override the rows for your specific case.

Source for current amounts: Connecticut DMV. Verify on the official agency page before paying — dollar amounts vary by county, weight class, vehicle age, and powertrain.
