Quick answer: U.S. residential electricity averaged 18.83 cents per kWh in April 2026, up 7.3% from a year earlier — the largest annual increase in the 2023–2026 stretch EIA has tracked (prior years ran 6.4%, 3.0%, and 5.0%). That's a quiet story next to this year's gas price swings, but it directly affects the roughly 80% of EV charging that DOE says happens at home. The math still favors EVs by a wide margin, but the margin is narrowing a little, and it's worth understanding why before you assume your charging cost is fixed.

What Actually Changed
According to the U.S. Energy Information Administration's own Electricity Monthly Update, the residential sector saw average revenue per kilowatt-hour — EIA's standard proxy for retail rates, since it doesn't survey posted prices directly — rise 7.3% in April 2026 compared to April 2025. That pushed the national residential average to 18.83 cents/kWh, up from roughly 15.04 cents/kWh in 2022. Independent trackers that compile the same underlying EIA data round this slightly differently (some report 7.4%), but the direction and scale are consistent across sources.
This is happening even as EIA forecasts lower wholesale electricity prices this summer than last summer, primarily because of cheaper natural gas delivered to power plants. That contrast suggests retail rates are being shaped by more than near-term generation costs alone — transmission and distribution investment, fuel-cost recovery timing, and regulatory decisions made months or years earlier can all show up in a bill even when this quarter's wholesale price is falling.
Home Charging Is a Different Market Than Public Charging
We've written before about how public EV charging pricing barely budged this spring even as gas prices swung sharply — AAA's tracked national average for public charging held around 41 cents per kWh through the volatility (see our breakdown of that gap). That's still true, and it's a real story. But it's a different market from what this piece is about.
Public fast-charging pricing is set by network operators (Tesla Supercharger, Electrify America, EVgo, and others) and tends to move independently of local utility rates. Home charging — which the U.S. Department of Energy says accounts for about 80% of all EV charging — is billed at your ordinary residential electricity rate, the same rate that just rose 7.3%. So while the public-charging number you might associate with EV cost stayed flat, the number that actually determines most EV owners' monthly bill has been quietly climbing.
| Area | Residential average revenue (¢/kWh, April 2026) | Difference from U.S. residential average |
|---|
| Northeast region | 25.91 | +38% |
| U.S. residential average | 18.83 | — |
| South Central region | 14.73 | -22% |
| Cheapest state (North Dakota) | 12.35 | -34% |
| Most expensive state (Hawaii) | 46.62 | +148% |
Regional groupings (Northeast, South Central) follow the source dataset's regional breakdown of EIA state-level residential data; all figures are residential-sector rates, not blended all-sector averages.
The spread matters more than the national average for any individual driver. A home charger in Connecticut or Massachusetts is paying more than double the per-kWh rate of a driver in North Dakota or Nebraska — a bigger swing than most people account for when they compare EV ownership costs using a single national number.
Does the Math Still Work? A Worked Example
Here's an illustrative calculation using national averages — your own numbers will vary by vehicle efficiency, local rate, and how much you drive, so treat this as a shape-of-the-problem exercise, not a personal quote. It also assumes the 30 kWh/100-mile figure reflects electricity drawn from the wall; if a vehicle's stated efficiency excludes charging losses, actual household electricity use could run modestly higher.
A typical EV consuming roughly 30 kWh per 100 miles, driven 12,000 miles a year, uses about 3,600 kWh annually. At the current national residential rate (18.83¢/kWh), that's about $678 a year to charge at home. A year ago, at the implied rate of roughly 17.55¢/kWh, the same usage would have cost about $632 — a difference of roughly $46 a year, or about $4 a month, from the rate increase alone.
| Scenario | Annual cost (12,000 mi/year, national avg. rate) |
|---|
| EV home charging, April 2025 rate | ~$632 |
| EV home charging, April 2026 rate (current) | ~$678 |
| Comparable gas car (25 mpg, AAA's national average of $3.83/gal, week of July 6, 2026) | ~$1,838 |
Even with the increase, home charging at the national average rate is still roughly $1,160 a year cheaper than a comparable gas car at AAA's current pump price — down only slightly from about a $1,192 gap a year ago. In other words: the electricity rate increase is real and worth watching, but it has trimmed the EV cost advantage by a few percent, not erased it. Drivers in higher-rate regions like the Northeast will see a smaller gap than this national-average example; drivers in the South Central states or the Pacific Northwest will see a wider one.
What's Driving the Increase
National retail electricity prices don't move in lockstep with short-term wholesale power prices. A household bill can reflect generation costs, fuel-cost adjustments, transmission and distribution investment, storm recovery, grid reliability spending, and state regulatory decisions made months or years before the bill arrives.
- Transmission and distribution investment. Utilities are replacing aging equipment, expanding capacity, and hardening systems against severe weather. Approved capital costs are generally recovered from customers over time.
- Growing electricity demand. Data centers, manufacturing projects, electrification, and population growth are increasing expected grid demand in several regions, though the actual bill impact varies by utility and depends on how regulators allocate infrastructure costs — this is a regional pressure, not a single confirmed national cause.
- Fuel and purchased-power costs. Natural gas remains the largest source of U.S. electricity generation. Even when near-term wholesale prices ease, retail rates may still reflect earlier fuel costs, hedging arrangements, and delayed regulatory adjustments.
These are broad electricity-system trends, not costs created solely by EV adoption. They affect households with and without an EV, though EV owners are more exposed simply because home charging adds to total electricity consumption.
What Drivers Should Actually Do
- Check your actual local rate, not the national average. The regional spread above is large enough that a national figure can mislead in either direction.
- If your utility offers time-of-use rates, look into off-peak charging. Many utilities charge less overnight, which is also typically when a home EV charger runs anyway.
- Don't assume public fast-charging pricing tells you what home charging costs. They're different markets that move independently, as this spring showed.
- Re-run your ownership cost comparison periodically, not just once at purchase. A 7% swing in a major input is exactly the kind of thing a one-time calculation misses.
If you're looking at a home charger install specifically, note that the federal 30C tax credit is no longer available for qualifying charging property placed in service after June 30, 2026 — worth factoring in alongside the electricity rate trend if you're budgeting for a new setup.
Our Take
Every EV cost conversation this year has been about gas price swings and tariff uncertainty — flashy, headline-friendly numbers. Meanwhile the actual bill that shows up in EV owners' inboxes every month has been climbing quietly by single-digit percentages, which is exactly the kind of change that's easy to miss and adds up anyway. The good news: it hasn't changed the basic math. The less good news: "hasn't changed the basic math yet" is doing some work in that sentence.
