EV vs. Gas: The True 5-Year Cost of Ownership (2026 Math)

The short answer

Across 5 years and 75,000 miles, a mainstream EV averages $31,200 total cost of ownership vs. $37,800 for an equivalent gas SUV — about $6,600 of net savings on the EV side, ~$1,320 per year.

But that's the median. The actual answer depends heavily on:

• Your annual mileage (high mileage favors EV; low mileage doesn't)
• Your home electricity rate (under $0.18/kWh favors EV; over $0.30/kWh narrows the gap)
• Whether you have home charging (renters with apartment parking lose most of the EV cost advantage)
• Your state's EV tax credit and registration fee structure (varies $1,500/yr in either direction)
• The specific models being compared (luxury EV vs. mainstream gas car ≠ apples to apples)

This guide walks the math line-by-line so you can model your own situation.

The 6 cost categories that matter

A 5-year TCO comparison rolls up six numbers. Most "EVs are cheaper" articles cherry-pick the favorable ones. Here's all six, both directions:

1. Purchase price (after rebates and tax credits)
2. Fuel/charging cost over 75,000 miles
3. Insurance premium (EVs are usually higher)
4. Maintenance + tires (EVs win on maintenance, lose slightly on tires)
5. Depreciation (highly model-specific; some EVs depreciate sharply faster than gas equivalents)
6. State-specific incentives, EV registration fees, and HOV/access perks

Add them all and divide by 5 for an annualized true cost.

The line-by-line comparison

Comparing two real 2026 vehicles: A $32,000 mainstream gas compact SUV (e.g., Honda CR-V LX, Toyota RAV4 LE) vs. a $42,000 EV (e.g., Hyundai Ioniq 5 SE, Tesla Model Y RWD), both held 5 years and 75,000 miles.

Purchase price after incentives

• Gas SUV: $32,000 (no incentive)
• EV: $42,000 minus the federal $7,500 clean-vehicle credit (if eligible) = $34,500 net

The gap closes to $2,500 in favor of gas at purchase.

Fuel vs. charging over 75,000 miles

• Gas SUV at 30 MPG, $3.80/gal: 2,500 gallons × $3.80 = $9,500
• EV at 3.3 mi/kWh, $0.17/kWh (national avg home rate): 22,727 kWh × $0.17 = $3,864

EV saves $5,636 over 5 years on fuel alone.

If your electricity costs more (California averages $0.34/kWh; many Northeast states are $0.25/kWh+), recalculate. At $0.30/kWh, the EV fuel cost rises to $6,818 and the savings narrow to $2,682.

Insurance premium delta

EVs cost roughly 15–20% more to insure than equivalent gas vehicles. The reasons: higher repair costs (battery integrity, sensor calibrations), more total-loss risk (battery damage often totals the car), and fewer specialty repair shops.

• Gas SUV avg 5-yr insurance: ~$7,200
• EV avg 5-yr insurance: ~$8,500

EV loses $1,300 to insurance.

Maintenance + tires

EVs have ~60% fewer moving parts. No oil changes, no spark plugs, no transmission fluid, no exhaust system, no fuel filters, no timing belts. Brake pads last 2–3x longer because of regenerative braking.

• Gas SUV 5-yr maintenance: ~$3,800 (oil, brakes, fluids, plugs, belts, ~1 unscheduled repair)
• EV 5-yr maintenance: ~$1,400 (cabin filter, brake fluid, tire rotations, battery coolant flush at year 4)

EV saves $2,400 on maintenance.

Tires: EVs are heavier (battery weight) and have instant torque, so tire wear is roughly 15–25% faster. Add ~$400 over 5 years to the EV side.

Depreciation

This is where models diverge sharply. Some EVs (Tesla Model Y, Hyundai Ioniq 5) hold value comparable to top gas SUVs. Others (Nissan Leaf, older Bolt, anything with a battery-tech generation behind it) depreciate dramatically faster.

5-year value retention (% of original MSRP):

• Honda CR-V: ~58% retained
• Toyota RAV4: ~62% retained
• Tesla Model Y: ~52% retained
• Hyundai Ioniq 5: ~50% retained
• Nissan Leaf: ~38% retained
• First-gen Chevy Bolt: ~35% retained

Comparing CR-V (~58% retained on $32,000 = $13,440 lost) vs. Ioniq 5 (~50% retained on $42,000 sticker = $21,000 lost), the EV loses an additional $7,560 to depreciation.

State-specific extras

• Most states: $0–$200/yr extra EV registration fee (to offset gas-tax revenue loss). Over 5 years: $0–$1,000 cost to EV.
• California, Washington, Colorado, New York, New Jersey, Massachusetts: state EV credits or rebates of $500–$2,500 (one-time, often layered with federal).
• HOV access: some states (CA, VA, WA, AZ) allow solo-driver HOV-lane access for EVs. For commuters this can save 30–60 minutes/day; impossible to model in dollars but real.

Assume net $200 cost to EV over 5 years for most states.

The line-item TCO totals

Summing all six categories for our comparison:

In this specific example with these specific assumptions, the gas SUV is cheaper by $3,924 over 5 years. The fuel and maintenance savings of the EV are completely consumed by the depreciation gap.

When the EV wins

The EV math flips in these scenarios:

1. High annual mileage (15,000+ miles/yr). Fuel savings scale with miles; depreciation is roughly flat. At 18,000 miles/yr, the EV's fuel savings grow to ~$8,500 over 5 years and the gas SUV's lead disappears.
2. Cheap home electricity (under $0.13/kWh). Common in much of the South and Midwest. Adds another $1,800–$2,400 to EV savings.
3. Holding the car 8+ years. Depreciation flattens after year 5; the EV's lower running costs keep compounding. At year 8, most EVs break even or pull ahead.
4. High-retention EVs (Tesla, top-tier Hyundai/Kia) vs. an aging gas model.
5. Solar panels providing essentially free charging.

When gas still wins (and probably will for a while)

1. Low annual mileage (under 8,000 miles/yr). Fuel savings are small; the higher purchase price never amortizes.
2. High electricity rates (over $0.30/kWh). Common in CA, NY, MA, HI. Reduces or eliminates the fuel advantage.
3. No home charging. Public DC fast-charging routinely costs $0.40–$0.55/kWh — wiping out the cost advantage entirely.
4. You'll sell within 3 years. Year-1 EV depreciation is brutal; gas vehicles drop more gradually.
5. Buying a low-retention EV. First-gen Bolt, Leaf, and other older platforms are cost traps even at low purchase prices.

What our calculator does (and doesn't) factor in

Our EV vs. gas TCO calculator factors in: purchase price, federal/state tax credits, your specific annual mileage, your specific home electricity rate, model-specific MPG/efficiency, 5-year depreciation curves by model, insurance premium estimates by state, and maintenance cost averages by drivetrain.

It does NOT factor in: HOV-lane time savings, employer EV charging subsidies, solar offset on your home power bill, or specific local registration fee changes. These are real but model-dependent.

Run the calculator with your actual numbers. The answer for your situation is rarely the median answer.

Bottom line

EVs save real money on fuel and maintenance but often lose more to higher depreciation and insurance. The break-even depends on annual mileage, home electricity cost, and the specific models compared. High-mileage drivers with home charging and a top-retention EV (Tesla Model Y, Ioniq 5) usually win. Low-mileage drivers, apartment dwellers, and buyers of older EV platforms usually don't.

Don't let an advocacy headline make the decision for you. Run the math on your actual annual miles and your actual local electricity rate.
