How this compares nationally
This combination ranks 10,922 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1S Dual Large (22in) alone ranks 250 of 400 models for efficiency; Texas alone ranks 28 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 Texas electrician to quote the install before this math becomes a real decision.
