Electric Vehicle vs. Gas Vehicle: The Financial Truth

The primary marketing pitch for Electric Vehicles (EVs) is the massive reduction in daily fueling costs. However, electricity is not free, and the true financial advantage of an EV depends entirely on your highly localized electricity rates and the efficiency of the vehicle you choose.

This estimator cuts through the marketing hype. By comparing your exact local cost per kilowatt-hour (kWh) against the price of gasoline at your local pump, it calculates exactly how much money you will save (or lose) by switching to electric.

Understanding EV Efficiency Metrics

Gas cars measure efficiency in Miles Per Gallon (MPG). Electric vehicles measure efficiency in Miles per kWh (mi/kWh). A highly efficient sedan (like a Tesla Model 3) might achieve 4.0 mi/kWh. A massive electric truck (like a Ford F-150 Lightning) might only achieve 2.0 mi/kWh.

If you drive 15,000 miles a year in a truck getting 2.0 mi/kWh, you will need to purchase 7,500 kWh of electricity. If you live in a state like California where electricity costs 0.35/kWh,fuelingthatEVwillcostyou0.35/kWh, fueling that EV will cost you 2,625 a year—which might actually be more expensive than driving a hybrid gas vehicle.

The Mathematical Formula

To calculate this scenario accurately, the following formula is applied:

Sannual=(MMPG×Pgas)−(MEeff×Pelec)\small \begin{aligned} S_{annual} = \left( \frac{M}{MPG} \times P_{gas} \right) - \left( \frac{M}{E_{eff}} \times P_{elec} \right) \end{aligned}

Where:
SannualS_{annual}=
Annual Savings
M=
Miles Driven per Year
EeffE_{eff}=
EV Efficiency (Miles/kWh)

Frequently Asked Questions

Drastically. Home charging usually utilizes standard residential electricity rates (often 0.10to0.10 to 0.20 per kWh). Public DC Fast Chargers (like Superchargers) are sold at a massive premium, often costing 0.40to0.40 to 0.60 per kWh.

No, this calculator isolates pure fueling costs. However, EVs generally have significantly lower routine maintenance costs because they lack internal combustion engines, oil changes, and complex transmissions.
