Cost of a full charge

Covering the 2026 Kia EV9 GT's EPA-rated 260-mile range takes about 111.8 kWh, which costs about $15.39 at Montana'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 9,059 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Kia EV9 GT alone ranks 326 of 400 models for efficiency; Montana alone ranks 10 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 Montana electrician to quote the install before this math becomes a real decision.
