Oklahoma home charging cost for the 2026 Tesla Model 3 Performance

At Oklahoma's residential electricity rate of 13.37¢/kWh, a 2026 Tesla Model 3 Performance (rated 29.6 kWh per 100 miles by the EPA) costs $3.96 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: 75.3% 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 Tesla Model 3 Performance costs roughly $593 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 $1,810 a year.

Cost of a full charge

Covering the 2026 Tesla Model 3 Performance's EPA-rated 309-mile range takes about 91.4 kWh, which costs about $12.22 at Oklahoma's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Where this ranks

This combination ranks 840 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Tesla Model 3 Performance alone ranks 52 of 400 models for efficiency; Oklahoma alone ranks 5 of 51 states for electricity price.

Next step: home charger installation

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

The methodology guide names the exact EIA and EPA tables behind this page's numbers. 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.
