As electric vehicles (EVs) continue to gain market share across North America and Europe, many drivers face the same central question: How much money will I actually save on fuel by switching from a traditional gasoline car to an electric vehicle?
While the initial purchase price of an EV can be higher, lower operational and home charging costs often create significant long-term financial savings. Understanding how to calculate and compare these running costs is key to determining your personal return on investment (ROI).

Charging losses account for electricity lost during the charging process. If your vehicle's consumption figure already includes electricity measured at the wall, set charging losses to 0%.

These figures are estimates based on your inputs and do not include vehicle purchase prices, insurance, maintenance, taxes, or other ownership costs.
1. The Financial Comparison: Gas vs. Electricity
Internal combustion engine (ICE) vehicles convert liquid fuel into kinetic energy with a thermal efficiency of roughly 20% to 30%. The rest of the energy is lost as heat. In contrast, electric drivelines operate at over 80% efficiency, converting grid power directly into motion.
Because grid electricity cost per kilowatt-hour (kWh) is significantly lower than equivalent petroleum energy, driving an EV costs a fraction per mile compared to conventional cars.
2. Factors Influencing Your EV Charging Costs
Your actual savings depend heavily on where and when you charge your vehicle:
- Home Level 2 Charging: Charging overnight on off-peak residential utility tariffs provides the lowest cost per mile.
- Public DC Fast Charging: Commercial charging networks frequently charge higher rates per kWh to cover infrastructure costs, reducing the per-mile cost advantage compared to home charging.
- Solar Integration: Pair your EV home charger with residential rooftop solar panels to charge your car using zero-cost green energy.
3. Long-Term Maintenance and Operational Benefits
In addition to fuel savings, electric vehicles carry lower routine maintenance expenses. EVs have fewer moving parts, eliminating oil changes, spark plug replacements, and transmission fluid services. Furthermore, regenerative braking systems reduce wear on brake pads and rotors.
