How to Use This EV vs Gas Calculator
This calculator provides a comprehensive comparison of electric and gas vehicle ownership costs over time. Unlike simple monthly payment calculators, it accounts for the full picture: fuel costs, maintenance differences, insurance, tax incentives, and how depreciation affects your true cost of ownership.
- Enter vehicle details for both options. Use actual MSRP or purchase prices. For EVs, enter efficiency in miles per kWh (found in EPA ratings—Tesla Model 3 is about 3.5-4.0). For gas vehicles, enter MPG from EPA estimates.
- Adjust insurance and maintenance estimates. EVs typically have higher insurance (more expensive to repair) but lower maintenance (no oil changes, less brake wear). The defaults are industry averages, but your quotes may differ.
- Set your shared parameters. Your annual mileage significantly impacts fuel cost differences. Local electricity rates and gas prices matter—check your utility bill and local gas stations for accurate figures.
- Include applicable tax credits. The federal credit is up to $7,500 for qualifying EVs, but not all vehicles qualify. Check IRS guidelines for your specific vehicle.
- Configure financing. If paying cash, set interest rate to 0%. Otherwise, enter your expected loan terms. Down payment affects both the loan amount and upfront costs.
- Review the break-even analysis. The chart shows when (or if) the EV becomes cheaper overall. A shorter ownership period may favor gas; longer periods often favor EVs due to fuel savings.
How It Works
Total Cost of Ownership Components
Total cost of ownership (TCO) goes far beyond the sticker price. It includes purchase price (minus any tax credits), financing costs, fuel/energy, maintenance and repairs, insurance, and depreciation (the value you lose over time). This calculator tracks all these components year by year to show the true cost of each option.
Why EVs Have Lower Operating Costs
Electricity is cheaper than gasoline per mile driven. At average U.S. rates, an EV costs about $0.04 per mile for fuel versus $0.12 per mile for a 30 MPG gas car at $3.50/gallon. That's $480/year vs $1,400/year for a 12,000-mile driver—nearly $1,000 annual savings on fuel alone.
Maintenance savings add up too. EVs have no oil changes, transmission fluid, spark plugs, or exhaust systems. Regenerative braking reduces brake pad wear by 50% or more. The typical EV saves $400-600 annually on maintenance compared to gas vehicles.
The Purchase Price Gap
EVs typically cost $5,000-15,000 more than comparable gas vehicles upfront. This is the primary barrier to EV adoption. However, the federal tax credit (up to $7,500), state incentives, and lower operating costs can offset this premium over time. This calculator shows exactly when that crossover happens.
Tax Credits Explained
The federal EV tax credit provides up to $7,500 for qualifying new EVs purchased after 2023. To qualify for the full amount, vehicles must meet battery sourcing and final assembly requirements. Your income must be below $150,000 (single) or $300,000 (married filing jointly). Some states offer additional credits. This calculator applies the credit immediately to the EV's effective purchase price.
Depreciation Differences
Historically, EVs depreciated faster than gas cars due to rapid technology improvements and battery concerns. This model assumes EVs lose 50% of value in the first 5 years versus 45% for gas vehicles. However, popular EVs like Tesla often hold value better. After 5 years, both vehicle types depreciate more slowly at about 5% per year.
Examples
Example 1: Tesla Model 3 vs Toyota Camry
A popular comparison between a $43,000 Tesla Model 3 (3.5 mi/kWh) and a $28,000 Toyota Camry (32 MPG):
- After $7,500 tax credit, the Tesla's effective price is $35,500
- Annual fuel: Tesla ~$480 vs Camry ~$1,310
- Annual maintenance: Tesla $600 vs Camry $1,200
- Break-even point: approximately Year 5
- 10-year savings with Tesla: ~$4,500
Example 2: Chevy Bolt vs Honda Civic
Comparing a more affordable EV ($27,000 Bolt, 4.0 mi/kWh) vs a compact car ($25,000 Civic, 36 MPG):
- After tax credit, the Bolt costs $19,500
- Annual fuel: Bolt ~$420 vs Civic ~$1,170
- Break-even point: Year 1 (EV cheaper from the start)
- 10-year savings with Bolt: ~$9,000
This is one of the strongest EV value propositions available.
Example 3: F-150 Lightning vs F-150 Gas
Comparing trucks: $55,000 Lightning (2.2 mi/kWh) vs $45,000 F-150 (22 MPG):
- After tax credit, the Lightning costs $47,500
- Annual fuel: Lightning ~$760 vs F-150 ~$1,910
- Break-even point: approximately Year 3
- 10-year savings with Lightning: ~$8,000
EV trucks benefit from the higher fuel consumption of gas trucks, making the fuel savings more dramatic.
Frequently Asked Questions
Are electric cars cheaper to own?
It depends on your situation. EVs typically have higher upfront costs but lower operating costs. With federal tax credits, lower fuel costs (electricity vs gas), and reduced maintenance, many EVs become cheaper over 5-10 years of ownership. The break-even point varies based on purchase price, local electricity rates, gas prices, and how much you drive.
How much does it cost to charge an EV?
At home, charging costs vary by your electricity rate. At the national average of $0.14/kWh, driving 12,000 miles in an efficient EV (3.5 mi/kWh) costs about $480/year—far less than gas. Public charging costs more: Level 2 chargers typically cost $0.20-0.30/kWh, and DC fast chargers can cost $0.30-0.60/kWh or more.
Do EVs have lower maintenance costs?
Yes, significantly. EVs have fewer moving parts—no oil changes, transmission fluid, spark plugs, or timing belts. Regenerative braking reduces brake wear. Typical EV maintenance costs $600-800/year vs $1,200-1,500 for gas cars. The main future expense is battery replacement, but modern batteries often last 200,000+ miles.
What is the federal EV tax credit?
The federal EV tax credit offers up to $7,500 for qualifying new EVs purchased after 2023. The vehicle must meet battery sourcing and assembly requirements, and your income must be below certain thresholds ($150K single, $300K joint). Some vehicles qualify for the full credit, others for $3,750, and some don't qualify at all. Used EVs may qualify for up to $4,000.
How long do EV batteries last?
Modern EV batteries typically last 200,000-300,000 miles or 15-20 years. Most manufacturers warranty batteries for 8 years/100,000 miles. Battery degradation does occur—expect to retain 80-90% capacity after 100,000 miles. Replacement costs have dropped dramatically and continue to fall, currently around $5,000-15,000 depending on the vehicle.
Do EVs depreciate faster than gas cars?
EVs have historically depreciated faster due to rapid technology improvements and battery concerns. However, this is changing as the market matures. Tesla models often hold value better than average. Used EV values have stabilized as buyers become more comfortable with the technology. Depreciation varies significantly by brand and model.
Is it cheaper to charge at home or at a station?
Home charging is almost always cheaper. At $0.14/kWh (national average), home charging costs about $4-5 to add 100 miles of range. Public Level 2 charging costs $6-10 for the same range. DC fast charging costs $12-25+ for 100 miles. If you have solar panels or time-of-use electricity rates, home charging can be even cheaper—sometimes under $0.05/kWh.
