Fuel vs EV Total Cost of Ownership
Compare gas car vs electric vehicle total ownership costs. Calculate fuel savings, maintenance, depreciation, and find your breakeven point with detailed.
Formula
TCO = Purchase Price - Credits + Fuel/Energy + Maintenance + Insurance + Depreciation + Registration
All ownership costs over the period. Fuel: miles / efficiency × price. Maintenance: miles × per-mile cost. Depreciation: purchase × (1 - retention rate)^years.
Worked Examples
Example 1: Average Commuter
Problem:12K miles/year, 5 years. Gas: $35K car, 28 MPG, $3.50/gal. EV: $45K, 3.5 mi/kWh, $0.13/kWh, $7,500 credit.
Solution:GAS TCO: Fuel: (60K / 28) × $3.50 = $7,500 Maintenance: 60K × $0.09 = $5,400 Insurance: $7,500 Depreciation: $35K × 56% = $19,600 Registration: $1,000 Total: $41,000 EV TCO: Energy: (60K / 3.5) × $0.13 = $2,229 Maintenance: 60K × $0.04 = $2,400 Insurance: $8,250 Depreciation: $37.5K × 67% = $25,125 Registration: $1,500 Total: $39,504 Savings: $1,496 (3.6%) Breakeven: ~4.5 years
Result:EV saves $1,500 over 5 years | Breakeven: 4.5 years | Marginal advantage
Example 2: High-Mileage Driver
Problem:20K miles/year, 5 years. Gas: $32K car, 25 MPG, $3.80/gal. EV: $42K, 3.3 mi/kWh, $0.11/kWh, $7,500 credit.
Solution:GAS TCO: Fuel: (100K / 25) × $3.80 = $15,200 Maintenance: 100K × $0.09 = $9,000 Insurance: $7,500 Depreciation: $18,200 Total: $50,900 EV TCO: Energy: (100K / 3.3) × $0.11 = $3,333 Maintenance: 100K × $0.04 = $4,000 Insurance: $8,250 Depreciation: $23,100 Total: $40,183 Savings: $10,717 (21%) Breakeven: ~2.5 years
Result:EV saves $10,700 over 5 years | Breakeven: 2.5 years | Strong EV advantage
Example 3: Budget Comparison
Problem:10K miles/year, 7 years. Gas: $25K used car, 32 MPG, $3.20/gal. EV: $35K, 4.0 mi/kWh, $0.15/kWh, $4,000 used credit.
Solution:GAS TCO: Fuel: (70K / 32) × $3.20 = $7,000 Maintenance: 70K × $0.10 = $7,000 (older car) Insurance: $8,400 Depreciation: $12,500 Total: $34,900 EV TCO: Energy: (70K / 4.0) × $0.15 = $2,625 Maintenance: 70K × $0.04 = $2,800 Insurance: $9,240 Depreciation: $18,600 Total: $38,265 Gas saves: $3,365 Breakeven: Never (gas wins) Budget gas car wins on TCO when purchase price gap is large and miles are low.
Result:Gas saves $3,400 | EV never breaks even | Low miles favor gas
Frequently Asked Questions
What is Total Cost of Ownership (TCO)?
TCO includes all ownership costs: purchase price, fuel/energy, maintenance, insurance, registration, taxes, and depreciation. Looking only at purchase price misses 50%+ of true cost. TCO reveals which vehicle is actually cheaper.
Are EVs really cheaper to operate?
Yes, operating costs are 50-70% lower. Electricity costs 3-5¢/mile vs 10-15¢/mile for gas. Maintenance is ~50% less (no oil changes, simpler drivetrain). But higher purchase price and insurance partially offset savings.
How long until EV savings offset higher price?
Breakeven typically 3-7 years depending on: price difference, miles driven, fuel prices, and electricity rates. High-mileage drivers break even faster. Federal tax credits significantly accelerate breakeven.
What's the federal EV tax credit?
Up to $7,500 for new EVs meeting requirements (assembly, battery sourcing). Used EVs: up to $4,000. Income limits apply. Credit reduces effective purchase price. Some states add additional incentives.
How does EV maintenance compare?
EVs eliminate: oil changes, transmission service, spark plugs, belts, exhaust. Still need: tires, brakes (last longer with regen), cabin filter, coolant. Typical: $0.04/mile vs $0.09/mile for gas cars.
Do EVs depreciate faster?
Currently yes (20%/year vs 15%), but improving as battery concerns fade and range increases. Tesla holds value well. Battery degradation fears drive depreciation. 8-year battery warranties help resale.
What about home charging installation?
Level 2 charger: $500-1500 installed. Pays back quickly vs public charging. Many utility rebates available. 240V outlet (like dryer) needed. Add to TCO if needed; most EV buyers install one.
How do gas prices affect the comparison?
Every $1 gas price increase = $400-600 more annual cost for average driver. At $5/gal, EV savings double. Gas price volatility is risk; electricity prices are more stable and predictable.
What about EV battery replacement?
Modern EV batteries last 200K-300K miles. Replacement cost: $5K-15K but rare within ownership period. 8-year warranties standard. Battery health typically 80%+ after 100K miles. Not a factor for most owners.
Should I wait for cheaper EVs?
Prices are dropping ($30K EVs now available). But waiting loses years of fuel savings. Calculate TCO with today's prices. Tax credits may phase out. Buy when TCO favors EV for your situation.
