Electric Vehicles (EVs) are not just a greener choice — for many Americans, they’re also a smart financial decision. Let’s break down how EVs save money through tax incentives, lower “fuel” costs, and long-term savings, and then run concrete examples to illustrate.

1. Tax Incentives & Rebates
- Federal Tax Credit
- Under U.S. law, EV buyers may be eligible for a federal tax credit of up to $7,500. Loanyzer+2AP News+2
- Thanks to recent rules, this credit can often be applied at the point of sale (i.e., you don’t necessarily wait until tax time). AP News
- However, there are eligibility conditions: income limits for buyers, vehicle price caps, and requirements around where the vehicle/battery is manufactured. TIME+2Loanyzer+2
- Used EV Credit
- There is also a credit for used EVs (up to about $4,000) under certain conditions. AP News
- Other Incentives
- Some U.S. states offer additional rebates, reduced registration fees, or tax incentives depending on local policy (varies widely).
Effect of Credit: This tax credit significantly lowers the effective purchase price of EVs — making the higher upfront cost more manageable.
2. Operating Costs: Electricity vs Gasoline
A big part of the cost advantage for EVs comes from how cheap “fuel” (i.e., electricity) is compared to gasoline.
- Cost per Mile: EVs
- According to GreenCars, typical EV “fuel” cost is around $0.03 to $0.05 per mile, assuming average electricity rates and typical EV efficiency. GreenCars
- According to EnergySage, depending on the EV and electricity rate, it could cost about 5 cents/mile for home charging.
- Cost per Mile: Gas Cars
- By contrast, many gasoline cars cost between $0.12 to $0.20 per mile in fuel.
- According to EVLife, at a national average electricity cost (~$0.15/kWh) and gas price (~$3.50/gal), EV fuel cost (converted into MPGe) works out to a big advantage over normal gas cars.
- Annual & Long-Term Savings
- Based on a study, EVs save on average 5.7 cents/mile compared to gasoline cars, using typical U.S. electricity and gas prices.
- Another model shows that if you drive ~13,476 miles/year (a U.S. average), EV charging might cost ~$675/year vs ~$2,025 for gasoline — saving ~$1,350/year.
- Maintenance costs are also lower in EVs because they have fewer moving parts (no oil changes, simpler motors). Alternative Fuels Data Center
3. Long-Term (5-Year and 10-Year) Savings — Example Calculations
Let’s run some example scenarios to estimate how much someone could save in fuel costs over 5 or 10 years by driving an EV compared to a gasoline car.
Assumptions for Example:
- Annual driving: 12,000 miles (a typical U.S. assumption)
- EV efficiency: ~3 miles per kWh (a reasonable average)
- Residential electricity cost: $0.16/kWh (this could vary)
- Gasoline car mpg: 30 mpg (just an assumption for example)
- Gasoline price: $3.15/gal (used in some cost models)
5-Year Savings Example
EV side:Electric Vehicles
- Energy consumption per year = 12,000 miles3 miles/kWh=4,000 kWh/year\frac{12,000 \text{ miles}}{3 \text{ miles/kWh}} = 4,000 \text{ kWh/year}3 miles/kWh12,000 miles=4,000 kWh/year
- Annual “fuel” cost (electricity) = 4,000 kWh×$0.16/kWh=$640/year4,000 \text{ kWh} \times \$0.16/\text{kWh} = \$640/\text{year}4,000 kWh×$0.16/kWh=$640/year
- Over 5 years: 5×$640=$3,2005 \times \$640 = \$3,2005×$640=$3,200
Gas car side:
- Fuel consumption per year = 12,000 miles30 mpg=400 gallons/year\frac{12,000 \text{ miles}}{30 \text{ mpg}} = 400 \text{ gallons/year}30 mpg12,000 miles=400 gallons/year
- Annual fuel cost = 400 gallons×$3.15/gal=$1,260/year400 \text{ gallons} \times \$3.15/\text{gal} = \$1,260/\text{year}400 gallons×$3.15/gal=$1,260/year
- Over 5 years: 5×$1,260=$6,3005 \times \$1,260 = \$6,3005×$1,260=$6,300
5-Year Fuel Savings by Driving EV: $6,300−$3,200=∗∗$3,100∗∗\$6,300 – \$3,200 = **\$3,100**$6,300−$3,200=∗∗$3,100∗∗
So, in this scenario, over 5 years, you save $3,100 just on “fuel.”
10-Year Savings Example
Using the same assumptions:
- EV “fuel” cost over 10 years = $640/year × 10 = $6,400
- Gas cost over 10 years = $1,260/year × 10 = $12,600
- 10-year fuel savings = $12,600 − $6,400 = $6,200
4. Combined Savings with Tax Credit
Now, combine these fuel savings with the $7,500 federal tax credit (or whatever your qualifying credit might be).
- If you get the $7,500 credit at purchase, that immediately reduces your effective upfront cost.
- Then, over 5 years, you might also save ~$3,100 on fuel (using the example).
- Over 10 years, fuel savings could be ~$6,200.
So, total savings (credit + energy) could be in the ballpark of $10,600 (5 years) or $13,700 (10 years) in this simplified example — not counting maintenance savings, which could further increase your benefit.
5. Risks & Things to Watch Out For
While EVs can save a lot, there are some caveats and risks:
- Electricity Rates Vary: If you live in a state with very high electricity costs, your per-mile EV cost will go up. Green Energy Consumers+1
- Public Charging Cost: Fast (DC) public charging can be expensive — sometimes approaching or even exceeding cost-equivalent of gas, depending on the station.
- Upfront EV Price: EVs often cost more upfront than ICE cars — though the tax credit helps.
- Credit Eligibility: Not everyone may qualify for the full $7,500 (or any) — depends on income, model, where the battery is made, etc.
- Depreciation: EVs may depreciate differently than gas cars (depends on model, battery, demand).
- Charging Infrastructure: If you don’t have a reliable way to charge (home charger, access to cheap public chargers), cost savings may shrink or be offset by other inconveniences.
6. Real-World Example: Tesla Model 3 vs a Gasoline Compact Car
Let’s do a rough comparison between a Tesla Model 3 and a typical gasoline compact car (say, something like a Honda Civic or similar).
- Model 3 cost (just for simplicity, assume MSRP ~$55,000; actual varies)
- Suppose you get $7,500 tax credit → effective “purchase benefit” = –$7,500
- Over 5 years, fuel savings (using our earlier assumptions) ~ $3,100
- Plus, EV maintenance savings (let’s assume a conservative $500/year in maintenance saving over gas car — realistic because EVs require less oil, fewer brake jobs, etc.) → $2,500 over 5 years. (Note: this is a rough assumption; real numbers differ by model.)
Total 5-year “advantage” (credit + fuel + maintenance) = $7,500+$3,100+$2,500=∗∗$13,100∗∗\$7,500 + \$3,100 + \$2,500 = **\$13,100**$7,500+$3,100+$2,500=∗∗$13,100∗∗
Of course, this doesn’t account for differences in insurance, financing costs, or depreciation, but it gives a sense of how powerful the tax credit + lower running cost can be.
7. Conclusion — Is It Cheaper to Own an EV Over 5–10 Years?
Short answer: Yes, very likely, especially if:
- You qualify for the EV tax credit.
- You drive a decent number of miles each year (to realize fuel savings).
- You can charge at home (preferably on a lower electricity rate).
Long-term: Over 5 to 10 years, the savings from reduced “fuel” costs + lower maintenance + the tax credit can add up to thousands of dollars, potentially justifying the often higher upfront price of an EV.
