EV charging cost in 2026
Last reviewed 2026-05-01 · ~7 min read
"How much will it cost me to charge?" is the most common question new EV owners ask. The honest answer is that it’s 60–80% cheaper than gas at home, but 2–3× more expensive than home at public DC fast chargers. This guide breaks down the math and the levers you control.
The basic math
EVs are priced by kWh, not gallons. The conversion: kWh per 100 miles × electricity rate ($/kWh) = cost per 100 miles. Modern EVs by class:
- Efficient sedan (Model 3, Ioniq 6, Polestar 2): 28 kWh/100mi
- Crossover (Model Y, Mach-E, Ioniq 5, ID.4): 32 kWh/100mi
- 3-row SUV (Rivian R1S, EV9, EQS SUV): 38 kWh/100mi
- Electric pickup (Lightning, R1T, Silverado EV): 42 kWh/100mi
At the US average 16¢/kWh, that crossover costs $5.10 per 100 miles charged at home — compared to about $12 for a 28-mpg gas crossover at $3.45/gallon. Driving 12,000 miles/year, the difference is about $830.
Home vs public — the big spread
US average residential electricity is 16¢/kWh. Public DC fast charging averages $0.42/kWh on Electrify America and EVgo; Tesla Superchargers $0.36/kWh. That’s 2–3× the home rate. A driver who DC-fast-charges 50% of miles spends roughly twice what an all-home charger spends — eliminating most of the EV vs gas savings.
The fix: structure your driving around home charging. A typical L2 charger adds 25–40 miles of range per hour — enough to refill any commute overnight. Save public DCFC for road trips and occasional emergencies.
The TOU plan multiplier
Most utilities now offer EV-specific time-of-use rates that drop overnight rates dramatically:
- PG&E EV2-A (CA): peak ~57¢/kWh, off-peak (midnight–3pm) ~31¢/kWh — for CA, still high but the spread matters.
- ConEd VoltageReady (NY): super-off-peak ~3¢/kWh midnight–8am.
- ComEd Hourly Pricing (IL): often 3–6¢/kWh overnight in spring/fall.
- Eversource EV plan (MA, CT): ~8–12¢/kWh overnight vs 26¢ peak.
Switching to a TOU plan with overnight charging can cut your charging bill 40–60% in many states. The downside: your non-charging usage may be more expensive on TOU. Run the numbers on your last bill before switching.
Cold weather costs more
EVs lose 10–25% efficiency below 32°F due to battery heating, cabin heating, and increased rolling resistance. A 28 kWh/100mi sedan becomes 32–35 kWh/100mi at 20°F. Plan for cold-weather charging cost ~15% higher than the annual average if you live in a cold climate.
Charging losses
You always pay for slightly more electricity than your battery receives. AC home charging loses ~10% in the onboard charger and battery management system. DC fast charging loses ~5%. Built into the calculator above. The kWh-per-100mi number on the EPA window sticker is "from the wall" — already includes charging losses.
Plug-in hybrid (PHEV) economics
PHEVs (Prius Prime, RAV4 Prime, Ford Escape PHEV) charge electric for the first 25–40 miles per day, then run on gas. If your typical drive is <40 miles and you can charge at home daily, you operate as an EV. If you regularly exceed the EV range or can’t charge at home, you operate as a hybrid. PHEV operating cost falls between BEV and hybrid; meaningful only if home-charged daily.
Charging cost vs total cost of ownership
This calculator covers operating cost only. For full TCO including purchase price, residual value, insurance, and maintenance, see the EV TCO calculator. Operating cost is roughly 25-40% of total ownership cost, so it’s a major but not dominant factor.
