How Much Does It Cost to Charge an EV?💰💰

📅 Updated February 2025 · 5 min read

One of the biggest advantages of owning an EV is ditching the gas pump. But what does it actually cost to charge at home? The answer depends on your state, your electricity rate, and how smart you are about when you charge.

The Simple Formula

Charging cost is calculated using this formula:

📐 Formula

Cost = (Battery size in kWh ÷ EV efficiency) × Local electricity rate
Example: 75 kWh battery × $0.16/kWh = $12 for a full charge

Level 1 vs. Level 2 Cost Comparison

The charger type doesn't change what you pay per kWh — your electricity rate does. But when you charge matters enormously if your utility offers Time-of-Use (TOU) rates.

Peak hours (typically 4–9 PM): Most expensive — up to $0.45/kWh in some CA markets

Off-peak hours (typically midnight–6 AM): Cheapest — sometimes as low as $0.07/kWh

How to Lower Your Charging Costs Further

1.Switch to a Time-of-Use (TOU) electricity plan — many utilities offer cheaper overnight rates specifically for EV owners.

2.Pair your EV charger with home solar panels to charge for near zero cost during the day.

3.Use your EV's built-in scheduling or a smart charger app to automatically charge during off-peak hours.

4.Claim the federal tax credit (30% of charger + installation costs) to offset upfront costs.
