EV Charging vs Gas: Complete Cost Breakdown

Home Charging: The Cheapest Option

Home charging is where the EV economics are most compelling. It's also how roughly 80% of all EV charging happens in the US, according to the Department of Energy's 2025 data. If you can charge at home, you're accessing the absolute cheapest per-mile energy cost available for personal transportation — and nothing else comes close. You can calculate your exact home charging costs using our EV charging cost calculator.

Level 1 Charging (120V Household Outlet)

This is as simple as plugging your EV into a standard wall outlet. The cost per kWh is whatever your home electricity rate is — nationally averaging $0.16 in 2026, according to EIA data. For a vehicle that gets about 3.5 miles per kWh, that works out to roughly $0.046 per mile.

The problem isn't cost — it's speed. Level 1 adds only 3-5 miles of range per hour. If you drive 40 miles per day, you'll need 8-13 hours of charging just to replenish what you used. Manageable if you plug in when you get home, but impractical for quick top-ups.

Cost for 1,000 miles: $46 at average US electricity rates.

Level 2 Charging (240V Home Charger)

A 240V Level 2 charger adds 25-40 miles of range per hour. You plug in when you get home, and by morning your battery is full. The equipment costs $300-$700, plus $300-$800 for professional installation. Total: $500-$1,500 one-time investment.

Cost for 1,000 miles: $46 at average US electricity rates, $26 at off-peak rates ($0.09/kWh).

Solar + Home Charging: The Ultimate Savings Combo

If you have solar panels, the economics become almost absurdly good. My setup produces enough solar to cover roughly 70% of my EV's annual energy needs — effectively driving on sunshine for free for about 8,400 miles per year. Total annual charging cost: $164. The petrol equivalent: $1,260-$1,800. Learn how to calculate your own solar production with my beginner's guide to solar.

Public Charging Networks: Cost and Convenience

When you can't charge at home — whether you're at work, running errands, or on a road trip — public charging is your backup. The cost varies enormously by network, and the differences are significant enough that choosing where to charge can save or cost you hundreds of dollars per year.

Workplace Charging

About 15% of US employers offer EV charging as of 2026, up from just 5% in 2022. Many are free — essentially a fringe benefit worth $300-$600 per year in fuel savings. When not free, it typically costs $0.20-$0.35/kWh.

Public Level 2 Charging

ChargePoint, Blink, and SemaConnect operate the largest public Level 2 networks. Pricing ranges from free (libraries, some shopping centers) to $0.30-$0.45/kWh. At $0.35/kWh, your cost per mile is about $0.10 — still cheaper than petrol, but 2-3x more than home charging. Use it as a supplement, not your primary method.

Tesla Destination Charging

Tesla's Destination Charger network includes over 15,000 locations — mostly hotels, restaurants, and resorts — offering free Level 2 charging. I've accumulated over 2,000 free miles per year from Destination Chargers. Non-Tesla EV owners are increasingly gaining access through adapters.

Fast Charging: When You Need Speed

DC fast charging (also called DCFC or Level 3 charging) is the EV equivalent of a gas station fill-up. You pull in, plug in, and 15-40 minutes later you're back on the road with 150-250 miles of added range. It's the closest experience to petrol refueling, but it comes at a premium price.

Tesla Supercharger

As of early 2026, Tesla Supercharger rates range from $0.25 to $0.52 per kWh depending on location and time. The national average is approximately $0.32/kWh. At this rate, 1,000 miles costs about $91 — still cheaper than petrol, but 2-3x more than home charging. Tesla also charges idle fees ($0.50-$1.00/minute) if you leave your car plugged in after charging completes. Just move your car when done and you'll never pay a fee.

Electrify America

Electrify America operates the largest non-Tesla fast charging network with over 900 stations. Rates are $0.43-$0.48/kWh for non-members, or $0.36/kWh with their $4/month Pass+ membership. For frequent users, the membership pays for itself after about 2 sessions per month.

Cost for 1,000 miles on EA (with Pass+): $103.

Cost for 1,000 miles on EA (without membership): $137 — approaching or exceeding petrol costs in some markets.

EVgo and ChargePoint Fast Charging

EVgo operates about 900 fast charging locations at $0.35-$0.45/kWh (member) or $0.40-$0.55/kWh (pay-as-you-go). ChargePoint's rates vary even more by location — I've seen $0.30/kWh in suburban Texas and $0.60/kWh in downtown San Francisco. Always check the app before driving to a station.

Petrol Station Costs: The Baseline

Let's establish our baseline for comparison. As of February 2026, the national average petrol price in the US is $3.15/gallon. But that national average masks enormous regional variation:

• Mississippi, Louisiana, Oklahoma: $2.65-$2.85/gallon
• Texas, Florida, Missouri: $2.90-$3.10/gallon
• Ohio, Illinois, Colorado: $3.10-$3.35/gallon
• California, Washington, Hawaii: $4.40-$5.20/gallon
• New York, Massachusetts: $3.50-$3.80/gallon

For a petrol car getting 30 MPG, the cost per mile ranges from $0.088 (cheap petrol states) to $0.173 (expensive petrol states). The national average is $0.105 per mile. This is the number every EV charging cost should be compared against.

Monthly and Annual Cost Comparison

Let's put all the EV charging scenarios side by side with petrol, assuming 1,000 miles per month (12,000 per year):

• Home Level 2 (off-peak, $0.09/kWh): $26/month, $309/year
• Home Level 2 (average, $0.16/kWh): $46/month, $548/year
• Home Level 1 (average, $0.16/kWh): $46/month, $548/year (same rate, slower speed)
• Workplace (free): $0/month, $0/year (for the miles you charge there)
• Public Level 2 ($0.35/kWh): $100/month, $1,200/year
• Tesla Supercharger ($0.32/kWh avg): $91/month, $1,097/year
• Electrify America with Pass+ ($0.36/kWh): $103/month, $1,236/year
• Electrify America without membership ($0.45/kWh): $129/month, $1,543/year
• Petrol (national avg, $3.15/gal, 30 MPG): $105/month, $1,260/year
• Petrol (California avg, $4.70/gal, 30 MPG): $157/month, $1,880/year

The key insight: home charging at average rates saves you roughly $59/month compared to petrol ($708/year). Home charging at off-peak rates saves $79/month ($951/year). But if you're relying entirely on public fast charging without a membership, you might actually spend more than petrol — especially if you live in a cheap-petrol state.

Road Trip Costs: EV vs Petrol

Let me give you a real example. Last summer, I drove from Austin to Santa Fe (620 miles one way) with my family. Here's the cost breakdown:

EV (Tesla Model 3 LR): 3 Supercharger stops along the way. Total energy consumed: 78 kWh beyond what we started with. At an average Supercharger rate of $0.34/kWh along that route: $26.50 each way. Round trip: $53. Total driving time including charging: 10.5 hours (including a 35-minute lunch stop that doubled as a charging session).

Petrol equivalent (30 MPG SUV): 620 miles at 30 MPG = 20.7 gallons each way. At $3.15/gallon average along that route: $65.20 each way. Round trip: $130.40. Total driving time: 9.5 hours (one brief stop for fuel and food).

Savings on this trip: $77.40 for the EV. The EV took about an hour longer due to charging stops, but saved 60% on fuel costs. On this particular route, I'd call that a clear win.

Now, on routes through rural areas with fewer chargers, the equation changes. I've done trips where the nearest fast charger was 40 miles off my route, adding 80+ miles and an hour of detour. In those cases, the cost savings are partially offset by the inconvenience. Always plan your route before an EV road trip — the planning takes 5-10 minutes and saves hours of stress.

Time-of-Use Electricity Rates Strategy

If your utility offers time-of-use (TOU) electricity pricing — and an increasing number do, especially in EV-heavy markets — you can dramatically reduce your charging costs by timing when you charge. Here's how TOU works and how to exploit it:

How TOU Rates Work

Instead of paying the same rate all day, your electricity costs vary by time. Typical TOU structure:

• Off-peak (10 PM - 2 PM): $0.08-$0.12/kWh
• Mid-peak (2 PM - 5 PM): $0.15-$0.20/kWh
• On-peak (5 PM - 10 PM): $0.25-$0.40/kWh

The strategy is simple: set your EV to start charging at 10 PM (or whenever your off-peak period begins), and it will be fully charged by morning at the lowest possible rate. Most EVs have built-in scheduling features for this exact purpose. My Model 3 is programmed to start charging at 11 PM every night — I plug in when I get home at 6 PM, but the car doesn't actually draw power until off-peak rates kick in.

How Much TOU Saves

Using off-peak rates instead of average residential rates saves roughly $0.07/kWh. Over 12,000 miles of annual driving at 3.5 miles per kWh (consuming about 3,430 kWh), that's $240 per year in savings. Not life-changing money, but it's free money for something as simple as setting a schedule on your car.

Some utilities offer EV-specific TOU plans with even deeper off-peak discounts. PG&E's EV2-A plan in California offers off-peak rates as low as $0.22/kWh during their super off-peak window (midnight to 3 PM), compared to on-peak rates of $0.55/kWh. The spread is enormous — charging during super off-peak saves more than $0.30/kWh compared to on-peak.

The Bottom Line: How Much Do You Really Save?

After three years of tracking every charging session, here's my honest assessment of annual EV charging costs versus what I would have spent on petrol:

• Home charging (90% of my miles): $493 per year at an average blended rate of $0.15/kWh
• Supercharger (8% of my miles): $88 per year
• Free Destination/Workplace charging (2% of my miles): $0
• Total annual EV charging cost: $581
• Estimated annual petrol cost (same miles, $3.15/gal, 30 MPG): $1,260
• Annual fuel savings: $679

That $679 per year is after accounting for mixed charging — mostly home, some fast charging, some free charging. It's a real number from real usage, not a theoretical best-case scenario. And it doesn't even include the maintenance savings, which add another $500-$700 per year on top of the fuel savings.

The bottom line is straightforward: if you can charge at home, an EV will save you $1,000-$1,500 per year on combined fuel and maintenance costs compared to a comparable petrol vehicle. If you can't charge at home, the savings shrink dramatically and the inconvenience increases. That's the single most important factor in whether an EV makes financial sense for you.
