EV vs Petrol Car in 2026: Which Actually Costs Less Over 5 Years?

EV prices have dropped significantly, but are they actually cheaper to own than a petrol car? The answer in 2026 is: it depends on how you run the numbers.

Let's do a realistic 5-year comparison using two similar vehicles.

The Matchup

Electric: 2026 Hyundai Ioniq 5 Standard Range — $38,500 MSRP

Petrol: 2026 Toyota RAV4 LE — $31,000 MSRP

Both are mid-size crossovers, the most popular vehicle type in America.

Purchase Price

EV: Hyundai Ioniq 5

  • MSRP: $38,500
  • Federal EV tax credit: -$7,500
  • Net price: $31,000

Petrol: Toyota RAV4

  • MSRP: $31,000
  • Net price: $31,000

With the federal tax credit, the upfront cost is essentially identical in 2026 for many popular EVs. This wasn't true even 2 years ago.

Fuel/Charging Costs (5 Years, 12,000 miles/year)

EV Charging

  • Average consumption: 3.5 miles/kWh
  • Total kWh needed: 17,143/year
  • Average electricity cost: $0.14/kWh (home charging)
  • Annual cost: $2,400
  • 5-year total: $12,000

Petrol Fuel

  • Average MPG: 30
  • Gallons needed: 400/year
  • Average gas price: $3.50/gallon
  • Annual cost: $1,400
  • 5-year total: $7,000

Wait — petrol is cheaper? In many areas, yes. Electricity rates vary wildly. In California ($0.25/kWh), EV charging costs more than gas. In Washington state ($0.10/kWh), it's half the cost. Home solar changes the equation entirely.

Advantage: Depends on your electricity rate

Maintenance (5 Years)

EV Maintenance

  • No oil changes
  • No transmission service
  • Brake pads last 2-3× longer (regenerative braking)
  • Tire rotation (EVs are heavier, wear tires faster)
  • Cabin air filter
  • Estimated 5-year total: $2,000–$3,000

Petrol Maintenance

  • Oil changes: 20 changes × $60 = $1,200
  • Transmission fluid: $200
  • Brake pads + rotors: $800
  • Air filters: $200
  • Spark plugs: $200
  • Tire rotation + other: $500
  • Estimated 5-year total: $3,100–$4,000

Advantage: EV by ~$1,000–$1,500

Insurance (5 Years)

EVs cost 15%–25% more to insure due to:

  • Higher repair costs (battery damage, specialized parts)
  • Higher replacement value
  • Fewer qualified repair shops

EV Insurance

  • Average: $1,800/year
  • 5-year total: $9,000

Petrol Insurance

  • Average: $1,500/year
  • 5-year total: $7,500

Advantage: Petrol by ~$1,500

Depreciation (5 Years)

This is the biggest cost of car ownership, and where the comparison gets interesting.

EV Depreciation

  • Year 1: 25% (driven by tech obsolescence fears)
  • Years 2–5: 12%/year
  • 5-year retained value: ~45% ($17,325)
  • Depreciation cost: $13,675 (after tax credit)

Petrol Depreciation

  • Year 1: 20%
  • Years 2–5: 10%/year
  • 5-year retained value: ~52% ($16,120)
  • Depreciation cost: $14,880

Advantage: EV by ~$1,200 (thanks to the tax credit lowering the effective purchase price)

The 5-Year Total Cost Comparison

Cost CategoryEV (Ioniq 5)Petrol (RAV4)
Net Purchase Price$31,000$31,000
Fuel/Charging$12,000$7,000
Maintenance$2,500$3,500
Insurance$9,000$7,500
Depreciation$13,675$14,880
Total 5-Year Cost$37,175$32,880

In this realistic scenario, the petrol car is ~$4,300 cheaper over 5 years. The EV's fuel cost disadvantage (at average electricity rates) and higher insurance outweigh the maintenance and depreciation savings.

When the EV Wins

The math flips in your favor if:

  • Your electricity rate is below $0.10/kWh (or you have solar)
  • You drive 15,000+ miles/year (fuel savings scale up)
  • Your state offers additional EV incentives ($2,000–$5,000 in some states)
  • Gas prices rise above $4/gallon

With cheap electricity + high miles, an EV can save $3,000–$5,000 over 5 years instead.

The Bottom Line

There is no universal answer. The "EVs are cheaper" claim and the "petrol is cheaper" claim are both true — depending on where you live, how much you drive, and your electricity costs.
