EV Savings Calculator 2026

How Fuel Savings Compound Over Time

Gas prices don't stay flat. Over the past 20 years, the national average gas price has risen from about $1.50/gallon in 2004 to over $3.50 today. That's roughly 4% annual growth, though with violent swings in between. The years when gas spiked to $5/gallon in California weren't anomalies. They were previews.

EV electricity rates are more stable. Residential electricity prices rose about 2% per year over the same period, and utilities are regulated, which dampens volatility. When gas spikes, your EV charging cost stays predictable. That stability has real financial value that a flat-rate comparison misses.

The fuel escalation slider in this calculator lets you model this. At 3% annual gas price growth—roughly the historical average—a driver paying $1,500/year in gas today pays $1,740 in year 5, $2,015 in year 10. The EV driver's electricity bill grows much more slowly. The gap widens with each passing year.

The Maintenance Piece Gets Underestimated

Gas car owners spend $1,200/year on maintenance on average, according to AAA. That includes oil changes ($100–$150 each, four times per year for most drivers), air filters, spark plugs every 30,000–100,000 miles, coolant flushes, transmission service every 30,000–60,000 miles, and brake jobs. The brake jobs alone average $300–$500 per axle when they're needed.

EVs skip most of that list. No oil. No spark plugs. No transmission. Brake pads last significantly longer because regenerative braking handles most deceleration. Coolant is used in some thermal management systems but far less maintenance-intensive. Annual maintenance for an EV typically runs $400–$700: tires, a cabin air filter, wiper blades, and the occasional brake job years later than you'd expect from a gas car.

At $600/year in savings, the maintenance gap adds $3,000 over 5 years, $6,000 over 10. It's not the dramatic number that tax credits produce, but it's reliable. Every year, regardless of gas prices or electricity rates, you're spending less on scheduled maintenance.

What the 10-Year Number Looks Like

Most people buying an EV today will own it for 8–12 years. That's the national average for car ownership, and EVs have fewer reasons to require replacement. No timing chain failures, no transmission rebuilds, fewer reasons to trade up because maintenance got expensive.

Run a typical scenario: 12,000 miles/year, $3.30/gallon average gas, 28 MPG gas car, 16¢/kWh electricity, 3.8 mi/kWh EV. Year 1 fuel savings: about $1,050. Year 5, with 3% gas escalation: $1,215 in fuel savings that year alone. Cumulative 5-year fuel savings: roughly $5,700. Cumulative 10-year fuel savings: over $13,000. Add maintenance savings of $600/year and the 10-year total tops $19,000.

That figure doesn't include the federal tax credit. Add $7,500 for buyers who qualify. Some states add another $2,000–$5,000. The break-even point on a $5,000 purchase price premium over a gas car equivalent: about 3 years for most moderate-mileage drivers in average-electricity-cost states.

High-mileage drivers—anyone doing 18,000+ miles per year—break even faster. Some are savings-positive by year 2. Commercial operators, Uber and Lyft drivers, and anyone driving 25,000+ miles annually have among the clearest financial cases for EVs available today.

How to Calculate Your EV Fuel Savings

The math isn't complicated. Five inputs, five minutes. Here's how to do it without a calculator:

Step 1: Annual gas cost. Take your yearly miles, divide by your car's MPG, multiply by your local gas price. A 28 MPG car driving 12,000 miles in Texas ($2.88/gas): 12,000 ÷ 28 × $2.88 = $1,234 per year in fuel.

Step 2: Annual EV charging cost. Take the same yearly miles, divide by the EV's efficiency in miles per kWh (Tesla Model 3: 3.8, Bolt: 4.1, Model Y: 3.5), multiply by your state's electricity rate in dollars (Texas: $0.141). That same 12,000 miles in a Model 3: 12,000 ÷ 3.8 × $0.141 = $446 per year. See the EV charging cost calculator for home vs public rate data by state.

Step 3: Fuel savings. $1,234 - $446 = $788/year in fuel savings for that Texas driver. Add the maintenance savings — typically $500–$800/year — and total annual savings are $1,300–$1,600. Over 10 years with gas prices rising 3% annually: $16,000+.

Step 4: Apply gas price escalation. Gas doesn't stay flat. At 3% annual growth (close to the 20-year average), a Texas driver paying $2.88/gallon today pays $3.87/gallon in year 10. The EV's electricity cost grows much slower — utilities are regulated and historically rise about 2% annually. Year 1 savings of $788 on fuel become $1,020 in year 10, from the same number of miles.

The calculator above does all five steps automatically. Knowing the math means you can sanity-check the result — and adjust for your specific situation, like if your utility offers time-of-use rates for overnight EV charging (common in California, Michigan, and Illinois — often cuts your effective rate by 30–40%). If you want per-mile figures instead, the EV cost per mile calculator breaks down the same data on a cents-per-mile basis.

Who Saves the Most — and Who Should Do More Math

Fuel and maintenance savings aren't evenly distributed. Three groups have a significantly stronger financial case than the average:

Truck owners. Gas pickups (20 MPG average) are the worst vehicles in the country for fuel economy. That makes the fuel savings gap with an electric truck the widest of any vehicle class. F-150 Lightning vs. gas F-150: roughly $2,000/year in fuel savings before maintenance. Silverado-to-Silverado EV comparison: similar. The Lightning's higher price is a real offset, but for anyone buying a $60,000+ gas truck, the EV economics close faster than people expect.

High-mileage drivers. Every mile you drive is a mile where the EV's cost-per-mile advantage adds up. Someone driving 20,000 miles/year saves about 66% more than someone driving 12,000 miles/year. Uber and Lyft drivers, contractors, and salespeople with long commutes are in a different savings category entirely. An Uber driver doing 40,000 miles/year in California can save $6,000–$8,000 annually on fuel alone — the EV pays for itself in under two years at that rate.

Drivers replacing inefficient gas cars. Swapping a 17 MPG SUV for an electric one produces roughly $1,600/year in fuel savings. Swapping a 38 MPG Prius for an EV produces about $550/year. Your current car's MPG is the biggest lever in the calculation — more than your state's gas price.

Two groups where the math is more complicated:

Low-mileage urban drivers. If you drive 6,000 miles/year and mostly charge at public stations, fuel savings are modest ($400–$600/year) and public charging is more expensive than home charging. The maintenance savings still apply, but the payback period on any purchase premium extends significantly. At $7,500 in federal tax credit, many lower-mileage drivers still come out ahead — but run the math for your actual mileage.

EV owners in Massachusetts, Connecticut, Rhode Island, and New Hampshire. Electricity costs there are high enough that fuel savings alone are $550–$650/year for a typical driver — less than half of what Washington state drivers see. State incentives in those states (Massachusetts: $3,500; Connecticut: $9,500) help close the total-cost gap, but fuel savings alone aren't compelling. The maintenance savings and total-cost story is more important than fuel savings alone in the Northeast.

What This Calculator Doesn't Include

This calculator covers fuel and maintenance costs — the operating savings that repeat every year. Three other factors matter for total cost of ownership, and they're not in the calculator because they're too variable to estimate reliably:

Purchase price premium. EVs typically cost $3,000–$10,000 more than comparable gas vehicles before incentives. After the federal $7,500 tax credit (if you qualify), that gap closes significantly. Some models — Chevy Bolt, Nissan Leaf — now cost less than their gas equivalents after the credit. Others — Rivian, Lucid — are priced well above any gas alternative. Your purchase price premium is the key input for break-even analysis.

Depreciation. EVs depreciate at roughly similar rates to gas cars in year 1–5, but the data is still thin for years 6–10. Battery degradation concerns (usually overblown for modern EVs with good thermal management) contribute to uncertainty. Used EV prices have softened since 2022, which is good for buyers and bad for current owners. This is the biggest unknown in a 10-year cost calculation.

Home charging equipment. A Level 2 home charger (240V) costs $300–$800 for the unit plus $200–$600 for electrician installation. Some EVs come with charging credits. Some utilities offer rebates. Federal tax credits cover 30% of the equipment and installation cost through 2032. If you're renting or can't install a charger, public charging costs more — factor that in before comparing to the home-charging rates the calculator uses.
