The Economics of Electric Mobility vs Combustion Engines
Electric motors operate at over 85% to 90% thermal efficiency, compared to internal combustion engines which waste roughly 70% to 80% of energy as useless heat. By decoupling transportation fuel from volatile global crude oil markets and leveraging off-peak residential power grids, drivers can permanently slash their cost per mile.
Use Cases
- ✓Prospective EV Buyer Financial Feasibility
Assess whether transitioning from an internal combustion engine (ICE) vehicle to a battery electric vehicle (BEV) will generate positive monthly cash flow.
- ✓Home Utility Time-of-Use (TOU) Rate Optimization
Determine the exact dollar savings of charging overnight between midnight and 6 AM during super-off-peak utility tariff windows.
- ✓Road Trip & Public DC Fast Charging Budgeting
Forecast long-distance interstate travel expenses when relying predominantly on Tesla Supercharger, Electrify America, or EVgo high-speed stations.
- ✓Corporate Fleet Electrification TCO
Model 5-year Total Cost of Ownership (TCO) fuel savings for corporate delivery vans and sales fleets transitioning away from diesel and unleaded gasoline.

Frequently Asked Questions
How much does it cost to fully charge an electric car at home?
A typical EV battery holds between 60 kWh and 80 kWh. At the US national average residential electricity rate of $0.16 per kWh, a complete 0% to 100% charge costs approximately $9.60 to $12.80, delivering 250 to 320 miles of driving range.
Is public DC fast charging more expensive than gas?
Public DC fast charging (which typically costs $0.35 to $0.48 per kWh) is roughly 2 to 3 times more expensive than charging at home. At $0.45/kWh, an EV costs about 12 to 14 cents per mile—comparable to a highly efficient 35+ MPG hybrid car, but still cheaper than an SUV averaging 18 to 22 MPG.
Why is there an AC charging loss factor?
When alternating current (AC) flows from your wall outlet into an EV, the vehicle's onboard converter converts it into direct current (DC) to store in the battery cells. This chemical and physical conversion generates heat, resulting in an industry-standard 10% to 12% energy loss.
How much can I save per year by switching to an EV?
Drivers averaging 13,500 miles per year who charge predominantly at home save an average of $800 to $1,400 annually on fuel compared to a 28 MPG gas vehicle paying $3.65 per gallon.
