Missouri home charging cost for the 2026 Rivian R1S All-Terrain Performance Dual Large Plus (20in)

In Missouri, home electricity runs 13.45¢/kWh — put a 2026 Rivian R1S All-Terrain Performance Dual Large Plus (20in)'s EPA-rated 46.9 kWh/100mi against that and 100 miles costs $6.31, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 60.6% less than gas per mile, here specifically.

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 Missouri electrician to quote the install before this math becomes a real decision.
