Calculate the full cost to charge your electric vehicle — at home on off-peak rates or at public DC fast chargers — and compare monthly totals.
Level 2 home chargers (240V) are the most cost-efficient option. The average US residential rate is $0.13–0.17/kWh. Off-peak time-of-use plans can reduce this to $0.08–0.10/kWh overnight.
Public DC fast chargers restore 100–200 miles in 20–40 minutes but cost $0.30–0.55/kWh depending on network and location. Membership plans can reduce per-session costs by 15–25%.
Not all energy drawn from the grid enters the battery. Level 2 chargers are typically 88–92% efficient. DC fast chargers are 85–92% efficient. This tool uses grid-side kWh for accurate cost estimates.
