Depreciation is usually the largest line — and the biggest source of uncertainty — so tune it to your own resale outlook. Insurance, registration & incentives default to Texas estimates.

Below this pump price, the Mazda CX-5 is cheaper to fuel than the EV is to charge; above it, the EV wins. (This is fuel only — see total cost to own below.)

Bottom line

The Tesla Model Y costs about $10,400 more to own than the Mazda CX-5 here today — but it pulls ahead on total cost to own if gas tops $7.55/gal (now $3.05).

Gas total includes its depreciation, fuel, insurance, maintenance, and registration (edit them in “Comparison car ownership” above).

How this is calculated

Annual electricity

(28 ÷ 100 × 12,000 mi) ÷ 0.88 = 3,818 kWh

Home charging cost

3,055 kWh × $0.14 = $440/yr

Public charging cost

764 kWh × $0.45 = $344/yr

Annual energy cost

$440 + $344 = $783/yr

Annual gas cost

(12,000 ÷ 26 mpg) × $3.05 = $1,408/yr

Fuel break-even gas price

$783 ÷ 462 gal = $1.70/gal

EV 5-year TCO

$26,094 + $3,917 + $16,300 + $3,250 + $1,000 − $0 = $50,561

Gas 5-year TCO

$13,200 + $7,038 + $14,180 + $5,500 + $250 = $40,168

5-year ownership difference

$50,561 − $40,168 = +$10,393 (EV pricier)

L2 payback

$1,300 ÷ (($0.45 − $0.14) × 3,055 kWh) = 1.4 yr

Estimates, not quotes. Figures use Texas averages and the assumptions above — your real costs depend on your utility plan, driving, insurer, and the incentives you actually qualify for. Verify with your utility, insurer, and state DMV before deciding.

How it works

1

Real per-state prices

Electricity and gas vary enormously by state. We use EIA data for each one, refreshed monthly — not a single national average.

2

Full cost of ownership

Most calculators stop at charging cost. We model depreciation, insurance, maintenance, fees, and incentives across five years.

3

Every formula shown

Open “How this is calculated” to see each number with your inputs plugged in. Nothing is a black box.

Frequently asked questions

What does “true cost to own” include?
Depreciation, energy (home + public charging), insurance, maintenance, and registration over five years, minus any one-time incentives — not just the cost to charge. Every input is editable and every formula is shown.
Where does the data come from?
Home electricity and gasoline prices come from the U.S. Energy Information Administration (EIA); vehicle efficiency comes from EPA FuelEconomy.gov. Insurance, fees, and incentives are state-level estimates you can override.
How often is it updated?
An automated pipeline refreshes the per-state electricity and gas prices monthly and re-stamps each page's “last updated” date.
Is it free, and are these official quotes?
It is completely free. The results are estimates for comparison, not quotes — verify with your utility, insurer, and state DMV before deciding.
