EV vs Gas Car Savings Calculator

Calculate total cost of ownership, fuel savings, and break-even point for an electric vehicle vs a gasoline car. Factor in charging costs and incentives.

The EV vs gas debate is more financially nuanced than either side usually admits. EVs typically cost more upfront but less to run. The break-even point depends on your driving habits, electricity rates, gas prices, and which specific models you're comparing. Rather than relying on general claims, the CalcHub EV Savings Calculator works out the numbers for your specific situation.

The True Cost of Ownership Inputs

For your gas car (or the comparable model):

Purchase price
MPG (miles per gallon)
Current gas price per gallon
Insurance cost
Maintenance costs (oil changes, tune-ups, etc.)

For the EV:

Purchase price
Miles per kWh (efficiency, typically 3–4 miles/kWh)
Home electricity rate (cents/kWh)
Public charging cost (if applicable)
Federal EV tax credit eligibility (up to $7,500 in the US)
State incentives
Insurance (typically 10–15% higher for EVs)

Fuel Cost Comparison at Current Prices

Assuming 15,000 miles/year driven:

Scenario	Gas Car (28 MPG)	EV (3.5 mi/kWh)
Fuel cost at $3.50 gas / $0.13/kWh	$1,875/year	$557/year
Fuel cost at $4.50 gas / $0.15/kWh	$2,411/year	$643/year
Fuel cost at $5.00 gas / $0.20/kWh	$2,679/year	$857/year
Annual savings (mid estimate)	—	~$1,500–1,800/year

At home charging rates, EVs are consistently cheaper to fuel. Even at $0.20/kWh (higher electricity rate), the EV wins significantly. The math only gets complicated if you're doing all charging at highway fast chargers, which can cost $0.40–0.55/kWh.

Maintenance Cost Difference

EVs have fewer mechanical parts — no oil changes, timing belts, spark plugs, or transmission fluid. Simplified maintenance:

Service	Gas Car	EV
Oil change (every 5,000 mi)	$60–100 × 3/year	$0
Transmission service (every 30k)	$150–250	$0
Spark plugs (every 30–100k)	$50–200	$0
Brake pads (every 30–50k)	$150–400	Less frequent (regen braking)
Tire rotation (every 5–7k)	$40–80 × 2/year	$40–80 × 2/year

Estimated maintenance savings: $800–1,200/year in favor of EVs. Over 10 years, that's $8,000–12,000.

Break-Even Analysis Example

Comparing a $28,000 Toyota Camry (32 MPG) vs a $40,000 Tesla Model 3 with $7,500 federal credit (net cost $32,500):

Price difference: $4,500 in favor of EV after credit
Annual fuel savings: ~$1,400
Annual maintenance savings: ~$900
Annual total savings: ~$2,300
Break-even on price difference: ~2 years

After the break-even, you're saving $2,300/year. Over 10 years total ownership, the EV comes out roughly $18,000 cheaper in this scenario.

Tips

Charging at home overnight is the game changer. Having a full charge every morning without ever going to a gas station is a lifestyle change that EV owners consistently value beyond the financial savings.
Check if your utility has EV rates. Many utilities offer time-of-use rates specifically for EV charging (off-peak overnight rates as low as $0.06–0.08/kWh) that make the fuel cost advantage even larger.
Factor resale value carefully. EV resale values have fluctuated more than gas cars as new models with better range and lower prices enter the market. Long-term owners tend to fare better than short-term owners on resale.

Does cold weather affect EV savings?

Yes. EV range drops 20–40% in very cold weather as the battery thermal management system consumes energy and battery chemistry slows. If you live in Minnesota and drive 150 miles some days, this matters for sizing. For average city driving, the range reduction is rarely a practical problem, just a financial consideration for heating costs.

What about apartment or condo dwellers without home charging?

Without home charging, you rely on workplace or public charging. Workplace charging is often free or subsidized. Public Level 2 charging costs $0.20–0.40/kWh — still cheaper than gas in most cases but the convenience advantage disappears. DC fast charging ($0.40–0.55/kWh) used regularly can narrow the fuel cost gap significantly.

Is a hybrid a better middle ground financially?

Hybrids eliminate range anxiety and charging infrastructure concerns. They save 30–50% on fuel vs a comparable gas car but don't reach EV fuel costs. For high-mileage drivers who regularly drive long distances and can't charge at home, a hybrid often makes better financial sense than a BEV.
