Are electric vehicles cheaper to own than gas cars over 5 years?

For most US drivers who commute regularly and primarily charge at home, EVs are cheaper over 5 years despite higher upfront costs. A Tesla Model 3 vs. Honda Accord comparison: EV wins by $4,000–$8,000 over 5 years through lower fuel costs ($550/yr vs. $1,800/yr), lower maintenance ($500/yr vs. $1,200/yr), and potentially the $7,500 federal tax credit. In high-electricity-cost areas or for low-mileage drivers, the savings are smaller. After 8–10 years, the gap widens significantly.

What are the hidden costs of EV ownership that reduce savings?

Hidden EV costs include: higher insurance premiums (5–15% more than comparable gas vehicles due to higher repair costs); home charger installation ($400–$1,500 if electrical panel upgrade needed); potential battery replacement after 8–15 years ($5,000–$20,000, though rare given warranty coverage); and faster depreciation on some older EV models. On the saving side, EVs require no oil changes, have fewer brake replacements (due to regenerative braking), and have fewer moving parts reducing long-term mechanical repair risk.
