Cost to Charge a BMW i4
Updated September 2026 · U.S. average rates
The short answer: at the national average rate, a full home charge of the BMW i4 (81 kWh usable, ~301 miles of range) costs about $15.21 — 5.4¢ per mile, or $53.65 per 1,000 miles. The same charge at a public DC fast charger runs roughly $34.83. Versus a 32-mpg gas car, home charging saves about $44.79 per 1,000 miles.
Living with a BMW i4: the cost story
The i4 proves a converted gas platform can still execute: it's one of the more efficient sports sedans here, and its charge curve — while 400-volt — is tuned well enough that road-trip stops stay reasonable.
The eDrive35/40 rear-drive cars are the efficiency picks; the M50 trades meaningful consumption for its pace. Either way, BMW's accurate range prediction makes cost planning less of a guessing game than most.

BMW i4 charging speed & home charger
Cost does not depend on speed — a kWh is a kWh — but time does. These estimates use the BMW i4's onboard AC limit (11 kW) and its typical DC fast-charging peak (~205 kW); real sessions taper as the battery fills.
Home charger sizing: the BMW i4 tops out at 11 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 277 miles, more than most daily driving. See Level 1 vs Level 2 and how many kWh it takes to charge an EV.

Using Texas's average residential rate (15.6¢/kWh) · national average 16.9¢ · includes ~10% AC charging losses. Rates vary by utility and plan — your bill is the source of truth.
