Missouri home charging cost for the 2027 Rivian R1T Quad (20in AT)

A 2027 Rivian R1T Quad (20in AT) draws 50.1 kWh per 100 miles per the EPA; at Missouri's 13.45¢/kWh residential rate that's $6.74 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home is much cheaper than gas here: 57.9% 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.
