Total Cost of an Electric Car in the US: How to Calculate TCO

What actually counts toward the real cost

A simple example: 4 years and 48,000 miles

Take an EV bought new for $38,000 actually paid, after any discounts and confirmed incentives. It's kept for 4 years, driven 12,000 miles a year, and resold conservatively for around $21,000.

In this example, depreciation is still the single biggest line. In other words, purchase price alone doesn't settle it: a pricier vehicle at checkout can end up cheaper if its real resale value holds up better. Compare current listings, insurance quotes, and model-specific maintenance plans instead of assuming that advantage.

Mileage: where the EV wins

At low mileage, depreciation and insurance dominate. At high mileage, every additional 1,000 miles adds far less energy cost than it would with a gas car.

For a rideshare or delivery driver logging 35,000–40,000 miles a year, energy weighs much more heavily in the result. A several-thousand-dollar annual gap is possible with mostly home or depot charging; frequent DC fast charging, commercial insurance, tires, and repair downtime can narrow or erase it.

Charging: the variable line item

The figures below reuse the assumptions from this app's charging-cost guide: about 26 kWh/100mi in everyday driving, versus roughly 32 kWh/100mi for highway fast charging. Adjust your annual mileage to see how much energy actually weighs in the TCO.

For frequent interstate or cross-country travel, add a separate road-trip scenario: usable 70–75 mph range, winter or desert consumption, towing if relevant, and the share bought at DC fast chargers. Home-only electricity can materially understate TCO for a driver who regularly crosses several states.

Driver-assistance software is a separate TCO line

Treat Tesla Full Self-Driving (Supervised) and similar paid assistance as software, not as range or a guaranteed residual-value asset. Add either the upfront purchase price or the subscription payments you actually expect to make. At exit, assign only the premium supported by comparable VIN-equipped used cars; a subscription and a promised future capability should receive no automatic resale value.

Resale: test three scenarios

The result depends heavily on resale price. Before buying, test at least these three scenarios against comparable listings — not just a theoretical valuation-tool number.

Cash, auto loan, lease with buyout, lease: comparing properly

Buying cash or financing means you carry the depreciation risk but keep a resale value. In a lease with a contractual return option or a lease, depreciation is baked into the payments, with return conditions attached. A fair comparison adds up every cash flow over the same period.

Key takeaways

An EV's real cost mostly comes down to the price actually paid, resale value, and mileage. Charging is rarely the single biggest line item, but it explains a large share of the advantage over a gas car once you drive a lot.

To compare fairly, keep the same time horizon, the same mileage, and three resale-value scenarios. A comparison that still holds up in the conservative scenario is far more trustworthy.
