2026 Tesla Model 3 Performance: home charging cost in Pennsylvania

At Pennsylvania's residential electricity rate of 20.9¢/kWh, a 2026 Tesla Model 3 Performance (rated 29.6 kWh per 100 miles by the EPA) costs $6.18 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 is much cheaper than gas here: 61.4% less than gas per mile, here specifically.

What a year of driving costs

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Tesla Model 3 Performance charged at home in Pennsylvania costs about $927/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,475 a year.

Cost of a full charge

How this compares nationally

This combination ranks 10,297 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; Pennsylvania alone ranks 37 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.
