Calculate how much you could save by switching to an electric vehicle. Compare fuel costs, maintenance expenses, and total ownership costs over multiple years between EV and gas vehicles.
Electric vehicles cost more upfront than comparable gas vehicles but typically cost substantially less to operate. Fuel cost per mile for EVs is typically $0.03-$0.05 vs. $0.10-$0.15 for gas vehicles — a 60-70% reduction in per-mile energy cost. Maintenance is lower too: no oil changes, brake pads last 2-3x longer due to regenerative braking, fewer moving parts in the drivetrain. Over a typical 10-year ownership horizon, an EV often saves $8,000-$15,000 in operating costs vs. a similar gas vehicle.
The economics aren't universally favorable, though. EVs typically carry $5,000-$15,000 higher purchase prices vs. similar gas vehicles (gap narrowing as battery costs decline). Insurance is often slightly higher. Charging infrastructure varies — home charging is cheapest ($0.10-$0.15/kWh) while DC fast charging on road trips can cost $0.40-$0.60/kWh, similar to gas costs per mile. Depreciation has historically been faster for EVs (battery degradation concerns, rapid technology improvements), though this is moderating with newer models. Federal tax credits (up to $7,500 for qualifying new EVs) and state incentives can substantially offset higher purchase price.
This calculator models operating cost differences over a multi-year horizon — fuel cost (gas vs. electricity at your rates), routine maintenance, and total cost of operation. It doesn't include purchase price differences, financing costs, insurance, or depreciation — those depend on specific vehicle choices and require separate analysis. Use it to: estimate the breakeven horizon where EV operating savings recoup higher purchase price, evaluate whether your specific usage pattern favors EV, and quantify the annual cost difference at your actual mileage and energy prices. For most drivers in moderate-to-high-mileage applications with home charging access, EVs produce meaningful long-term savings; for low-mileage drivers without home charging, the case is weaker.
Sales rep driving 24,000 miles/year. Gas car 28 MPG at $3.50/gal. EV 3.5 mi/kWh at $0.12/kWh home charging. Annual gas cost: (24,000 / 28) × $3.50 = $3,000 Annual EV cost: (24,000 / 3.5) × $0.12 = $823 Annual fuel savings: $2,177 Plus maintenance savings (~$700/year for EV vs. high-mileage gas): $700. Total annual savings: $2,877. 10-year savings: $28,770. Even with $10K EV premium (after credits), payback < 4 years. High-mileage drivers see the strongest EV operating economics. Bonus: HOV lane access (some states), depreciation increasingly favorable for popular EV models.
Retiree driving 6,000 miles/year. Gas car 32 MPG at $3.50/gal. EV 3.5 mi/kWh at $0.13/kWh. Annual gas cost: (6,000 / 32) × $3.50 = $656 Annual EV cost: (6,000 / 3.5) × $0.13 = $223 Annual fuel savings: $433 Plus modest maintenance savings: $400. Total annual savings: $833. 10-year savings: $8,330. With $10K EV premium, payback 12+ years. For low-mileage drivers, operating savings rarely justify EV premium over reasonable ownership horizons. Marginal case — the decision should probably hinge on personal preference, environmental priorities, and home charging convenience rather than operating economics.
Same 12K-mile driver as default, but California electricity rates ($0.32/kWh average tier). Annual gas cost: $1,500 Annual EV cost: (12,000 / 3.5) × $0.32 = $1,097 Annual fuel savings: only $403 (vs. $1,054 at $0.13/kWh) California electricity rates dramatically reduce EV operating advantage. CA-specific strategies: solar panels (essentially free EV charging from sun), time-of-use rates (charge at off-peak $0.18-$0.20/kWh instead of peak), and PG&E EV-A2 rate plan that's specifically EV-optimized. For Californians without solar or off-peak charging, EV operating savings can be 60% smaller than the national average. The case still works for high-mileage drivers but becomes marginal at low mileage. State EV incentives and HOV access partially compensate.
Use this calculator when comparing EV to gas vehicle purchase economics, evaluating switching costs for high-mileage drivers, or assessing whether your specific driving pattern and energy costs favor EV adoption.

Important EV-vs-gas considerations:
1. **Home charging is critical to economics.** Level 2 home charger ($500-$2,000 installed) enables overnight charging at residential rates ($0.08-$0.20/kWh). Without home charging, EV economics weaken substantially — DC fast charging costs $0.40-$0.60/kWh, similar per-mile cost to gas.
2. **Annual mileage drives savings.** Per-mile savings of $0.07-$0.10 produces $840-$1,200/year savings at 12K miles, but $2,100-$3,000 at 30K miles. High-mileage drivers see the strongest case.
3. **Electricity rate matters enormously.** Hawaii ($0.40/kWh) vs. Washington ($0.10/kWh) — 4x difference in per-mile cost. Know your specific rate and time-of-use options.
4. **EV efficiency varies by vehicle type.** Compact EVs: 4-5 mi/kWh. Mid-size EVs: 3-4 mi/kWh. EV trucks/SUVs: 1.8-2.5 mi/kWh. Cold-weather operation reduces efficiency 20-40%; hot-weather AC use 10-20%.
5. **Federal tax credit changes economics dramatically.** Up to $7,500 for qualifying new EVs (income limits and US-assembled requirements apply); $4,000 for used EVs. Verify current eligibility — rules change. Many state credits ($1,000-$7,500) layered on top.
6. **Depreciation is moderating.** Earlier EVs (pre-2018) depreciated fast due to battery concerns. Modern EVs (especially Tesla, Hyundai, Kia) depreciating closer to ICE norms. Battery health certifications now being introduced should further stabilize.
7. **Insurance often $200-$500/year higher** due to higher repair costs (battery replacement very expensive). Get quotes before purchase.
8. **Charging on road trips requires planning.** DC fast charging networks (Electrify America, Tesla Supercharger, EVgo) are growing but variable in coverage. Trip planning apps (PlugShare, ABRP) help. For frequent long-distance driving, EV may be impractical depending on region.
9. **Cold weather reduces range 20-40%.** Significant for northern climates with long drives. Battery preconditioning helps; plan accordingly.
10. **Look at total cost of ownership, not just sticker price.** Operating savings often outweigh higher upfront cost over 7-10 years. AAA and Consumer Reports publish total cost of ownership comparisons.
11. **Environmental considerations:** lifecycle emissions of EVs are typically 30-60% lower than ICE vehicles in most US grid mixes, dropping further as grids decarbonize. EV battery recycling improving rapidly.
12. **PHEVs as middle path.** Plug-in hybrids (PHEV) offer ~30-50 miles electric range plus gas backup. Good fit for buyers without home charging or with occasional long trips, but most operating cost benefit comes from charging at home for daily use.
