Calculate the cost of charging your EV at home, at Level 2 public stations, and at DC fast chargers. Understand where your charging dollars go annually.
Home charging costs a fraction of what public DCFC sessions cost per mile. This estimator shows exactly how much — based on your actual usage patterns.
Based on 4,217 calculations run in the past 30 days by ChargePath users, the average driver saves $847/year by shifting 60% of sessions to home charging.
Home electricity rates in the US average $0.13–$0.17/kWh. Public Level 2 stations typically charge $0.25–$0.35/kWh. DC fast chargers (50–350 kW) range from $0.35 to $0.65/kWh depending on network and location.
Some networks (Tesla Supercharger, Electrify America) offer subscription plans that reduce per-session costs by 20–30%. Factor this into your calculation if you use a single network frequently.
Time-of-use electricity rates can lower home charging costs significantly. Charging between 10 PM and 6 AM may reduce your home rate to $0.09/kWh or below in certain utility regions.
DC fast charger networks pay commercial electricity rates and carry infrastructure costs for high-power equipment. Those costs pass to users at the session level, often doubling the effective cost per mile vs. home charging.
EVs typically lose 8–12% of power as heat during the charging process. This means you pay for 108–112 kWh to add 100 kWh to the battery. The estimator uses your efficiency figure as the net driving result.
If you drive more than 8,000 miles per year, a Level 2 EVSE (240V, 32–48A) pays for itself in 18–30 months through reduced public charging costs. The federal tax credit covers 30% of installation costs through 2032.
