EV vs. gas: the total-cost math nobody finishes

Electric cars cost more to buy and less to run. Whether the trade works for you comes down to five numbers.

The EV-versus-gas argument is usually conducted in slogans — 'EVs are cheaper to run!' versus 'you'll never make back the premium!' Both can be true, for different drivers. The honest comparison is a total-cost-of-ownership calculation with five inputs: purchase price after incentives, energy cost, maintenance, depreciation, and insurance. Fill in your own numbers and the argument resolves itself.

The five inputs

  • Purchase price after incentives: compare real transaction prices, and apply any federal or state credits that actually apply to you (the federal clean-vehicle credit has income and vehicle caps, and has often been easier to capture through a lease).
  • Energy: home charging typically runs $0.03–0.06 per mile at average residential electricity rates; gas at 30 mpg and $3.40 a gallon is about $0.11 per mile. Public fast charging can cost as much as gas — the savings live at home.
  • Maintenance: no oil changes, no transmission, regenerative braking that saves the brake pads. Studies put EV maintenance around 30–40% cheaper over the ownership period.
  • Depreciation: historically the EV wild card. Rapid tech improvement and price cuts on new EVs have hammered used EV values in some years — great for used buyers, painful for new ones.
  • Insurance: EVs often cost 10–25% more to insure due to battery and repair costs.

A worked example

Compact EV vs. compact gas, 5 years, 12,000 miles a year
EV: $36,000 after a $7,500 credit, home charging at $0.04/mile = $2,400 fuel over 5 years, maintenance $1,800, insurance $9,500, resale value $15,000 → total 5-year cost about $34,700. Gas: $28,000, fuel at $0.11/mile = $6,600, maintenance $3,600, insurance $8,000, resale $13,500 → total about $32,700. The gas car wins by $2,000 here — but flip one input and it reverses: 20,000 miles a year saves the EV another $2,800 in fuel; losing the tax credit costs it $7,500; cheap overnight electricity at $0.03/mile widens the fuel gap further. The answer lives in your inputs, not the category.

The pattern across most honest comparisons: the more you drive and the cheaper your home electricity, the better the EV looks. Low-mileage drivers who can't charge at home rarely recover the purchase premium.

The home-charging dividing line

The single biggest factor isn't the car — it's your parking. With a garage or driveway and a Level 2 charger (installation typically $500–2,000), you fuel at the cheapest rate available, often on an off-peak utility plan, without ever visiting a station. Relying on public fast charging flips the economics: DC fast-charging rates of $0.40–0.60 per kWh work out to roughly gas-car fuel costs, plus your time. If you street-park with no workplace charging, a hybrid usually beats both pure options.

The used EV arbitrage
Steep early depreciation makes 2–3 year old EVs some of the best value in the used market — cars that sold for $50,000 trading in the high $20s with most of their battery warranty (typically 8 years/100,000 miles, federally mandated) still intact. Buying the depreciation someone else paid for is the strongest EV play going.

Costs people forget on both sides

  • EV: charger installation, possible electrical panel upgrade, higher registration fees in many states (offsetting lost gas taxes), winter range loss of 20–30% in cold climates.
  • EV: road-trip time cost — fast-charging stops add real minutes to long drives; price your time honestly if you road-trip often.
  • Gas: rising maintenance in years 6–10 (timing components, transmission service, exhaust, emissions repairs) that the EV never faces.
  • Both: tires. EVs are heavier and torquier and can eat tires 20% faster; either way, budget for a $700–1,200 set every 40,000–60,000 miles.
Don't buy the fuel savings twice
Dealers and ads love 'you'll save $8,000 in gas!' math that assumes maximum mileage, peak gas prices, and free electricity — while the EV's higher price, insurance, and depreciation quietly sit outside the frame. Any comparison that only counts categories where one side wins isn't a comparison; it's a pitch.

The worked example, line by line

Here is the five-year comparison from above laid out as a table so you can swap in your own numbers. Every figure is an estimate built on 12,000 miles a year, home charging at $0.04 per mile, gas at $3.40 a gallon, and typical 2025-2026 insurance quotes; change any input and the winner can flip, which is precisely the point.

Line itemEVGas
Price after incentives$36,000$28,000
Energy / fuel (5 yrs)$2,400$6,600
Maintenance (5 yrs)$1,800$3,600
Insurance (5 yrs)$9,500$8,000
Resale value at yr 5-$15,000-$13,500
Net 5-year cost$34,700$32,700
Five-year total cost, compact EV vs. compact gas car (estimates, 12,000 mi/yr)
Energy cost per mile by fueling method (estimates)
Home charging, off-peak$0.03/mi
Home charging, average rate$0.05/mi
Gas at 30 mpg, $3.40/gal$0.11/mi
DC fast charging$0.12/mi

Two sensitivity checks worth running before you decide. Mileage: at 20,000 miles a year the EV's fuel advantage grows to roughly $1,400 annually and the five-year verdict flips to the EV by about $2,800. Charging access: replace home charging with fast charging and the EV's fuel line nearly triples, erasing the maintenance advantage entirely. This is why two neighbors with identical cars can both be right about which one is cheaper — they are not running the same inputs. Build the table with your electricity rate, your commute, and real insurance quotes on both vehicles, and treat any claim that skips a row as marketing.

The hybrid answer most comparisons skip

The binary framing hides the option that wins for a large share of households: a conventional or plug-in hybrid. A compact hybrid typically costs $1,500-2,500 more than its gas twin, returns 45-55 mpg with no charging infrastructure required, and carries none of the fast-depreciation risk that has haunted used EV values. For the street-parker, the low-mileage driver, and the one-car family that road-trips, the hybrid captures most of the fuel savings with none of the lifestyle prerequisites. Run it as a third column in your own table; it is frequently the quiet winner while the loud argument continues overhead.

The bottom line

There is no universal winner. Drive a lot, charge at home on cheap electricity, capture the tax credit, and keep the car 8+ years: the EV likely wins by thousands. Drive under 8,000 miles a year with no home charging: gas or hybrid wins. Spend thirty minutes with your own five inputs — miles, electricity rate, incentives, insurance quotes, and resale estimates — and the right answer for your driveway will be obvious.
