EV vs Gas Calculator

Compare the true total cost of ownership — energy, maintenance, insurance, financing and incentives — plus break-even year and CO₂ impact, with live charts.

Cumulative cost over time

Everything spent on each car, year by year — purchase (net of credits), loan interest as it accrues, energy, maintenance and insurance. Where the lines cross is your break-even point.

What's counted: purchase price net of credits, home charger, loan interest (within your ownership window), fuel/energy with separate inflation rates, maintenance and insurance. Depreciation and resale value are not modeled — see the notes in the footer. Fine-tune every assumption on the other tabs; this page updates live.

The core comparison — everything else on the page builds on these numbers.

EV breaks even after 5 years

Cumulative savings over time

The gas car's running total minus the EV's. Above the dashed zero line, the EV is ahead; the crossing point is your break-even.

Financing model: both cars are financed on the same terms after your down payment. Interest is amortized over the loan and only the portion accruing within your ownership window is counted — so a 3-year ownership on a 5-year loan doesn't get charged all 5 years of interest.

Fuel-price trajectories and loan terms move the break-even year more than anything else.

Lifetime emissions comparison

Metric tons of CO₂ over your whole ownership period, at your grid mix.

Scope: the gas figure is tailpipe combustion (EPA: 8.887 kg CO₂ per gallon) and excludes upstream extraction and refining, which add roughly a quarter more. The EV figure covers electricity generation for your charging. Neither includes vehicle manufacturing.

An EV is only as clean as the electricity behind it — set your grid mix here.
