How much does it cost to charge a Rivian R1S?

At the U.S. average residential rate (16.9¢/kWh), a full home charge of the Rivian R1S (135 kWh, ~316 mi range) costs about $25.35 — 8.2¢ per mile. Public DC fast charging at ~43¢/kWh runs about $58.05 per full charge.

How long does it take to charge a Rivian R1S?

On a Level 2 home charger the Rivian R1S accepts up to 11.5 kW, so an empty-to-full charge takes about 13 hours (roughly 24 miles of range per hour). At a DC fast charger its ~220 kW peak gives a 10–80% charge in about 40 minutes. On a standard 120V outlet (Level 1), a full charge takes around 113 hours.

What home charger do I need for a Rivian R1S?

Any Level 2 (240V) charger works; the Rivian R1S's onboard charger caps AC charging at 11.5 kW, so a 48A unit on a 60A circuit reaches that limit — a more powerful charger will not charge it faster. The electricity cost is the same at any speed: $25.35 per full charge at the national-average rate.

Living with a Rivian R1S: the cost story

The R1S is the R1T's seven-seat sibling and one of the few EVs that genuinely replaces a large gas SUV for outdoorsy families. The cost math mirrors the truck's: high absolute consumption, big savings anyway versus the 15-mpg vehicles it typically replaces.

Its large pack makes home charging infrastructure worth doing right — a 48-amp circuit turns even a near-empty battery into a solved-by-morning problem, while a 32-amp unit can leave you short after back-to-back heavy days.

Rivian R1S charging speed & home charger

Cost does not depend on speed — a kWh is a kWh — but time does. These estimates use the Rivian R1S's onboard AC limit (11.5 kW) and its typical DC fast-charging peak (~220 kW); real sessions taper as the battery fills.

Home charger sizing: the Rivian R1S tops out at 11.5 kW on AC, so a 48-amp charger on a 60-amp circuit reaches its limit — a bigger unit adds nothing. Overnight (8 hours) on Level 2 restores about 190 miles, more than most daily driving. See Level 1 vs Level 2 and how many kWh it takes to charge an EV.
