2026 Volvo EX40, OK Charging Cost

Oklahoma home charging cost for the 2026 Volvo EX40

At Oklahoma's residential electricity rate of 13.37¢/kWh, a 2026 Volvo EX40 (rated 31.7 kWh per 100 miles by the EPA) costs $4.24 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. Charging at home costs a fraction of what gas would here: 73.5% less than gas per mile, here specifically.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Volvo EX40 costs roughly $636 a year to charge at home in Oklahoma, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,767 a year.

Cost of a full charge

Covering the 2026 Volvo EX40's EPA-rated 296-mile range takes about 93.8 kWh, which costs about $12.55 at Oklahoma's residential rate, figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

How this compares nationally

This combination ranks 1,581 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Volvo EX40 alone ranks 83 of 400 models for efficiency; Oklahoma alone ranks 5 of 51 states for electricity price.

Before you install a home charger in Oklahoma

The numbers above assume Level 2 home charging is already in place, the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

Ask a licensed Oklahoma electrician to quote the install before this math becomes a real decision.

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset, see the methodology guide. Oklahoma is one of the cheapest states for home electricity, the guide to why the cost varies so much by state covers what drives that.
