Sticker price and $/kWh get the headlines. Maintenance is the quiet line item where EVs often pull ahead—fewer fluids, no ignition service, and brake pads that last longer thanks to regenerative braking.
What disappears on an EV
Internal combustion engines need oil changes, spark plugs, timing belts or chains on a schedule, and engine air paths that clog with miles. Friction brakes do most of the stopping on gas cars, so pads and rotors wear steadily. Battery electric drivetrains remove that entire service stack.
What remains
You still pay for tire rotation, cabin filters, brake fluid intervals, battery thermal coolant, and diagnostic time. Tires may wear faster on some EVs (torque and mass)—model that separately. Maintenance savings are real but not infinite.
How to use the comparison
- Enter your annual kilometers (fleet odometer or personal average).
- Pick vehicle class—SUV and luxury multipliers reflect pricier parts and labor.
- Choose 5 or 10 years and optional battery replacement risk to see net savings after a hypothetical pack bill.
- Read cumulative totals, the dashed EV + pack risk line on the chart, and ICE-only line items you eliminate.
Most packs last well beyond a typical loan—see How long do EV batteries really last?.
Pair with EV vs. Gas Savings for energy costs and EV tire wear cost for rubber—honest TCO needs all three ledgers.
The true cost of ownership is the sum of energy, maintenance, tires, insurance, and depreciation. Start with maintenance: it is the easiest slice to quantify before you sign a loan or fleet contract.
