EV Monthly Charging Cost Calculator
Calculate your personalized monthly EV charging cost based on your state, EV model, and driving habits — with zero manual math.
📐 How We Calculated This
Formula: Monthly Cost = (Miles ÷ Efficiency) × Electricity Rate
We use EIA state electricity rates (auto-populated), EPA/DOE efficiency data for your EV model, and AAA gas prices for comparison. TOU rates are estimated at 30–50% below standard rates where applicable.
- Assumptions: Public charging is ~2× home rate. TOU off-peak is ~40% lower than standard.
- Limitations: This is an estimate. Actual costs vary by utility, driving style, and charging equipment.
- Sources: EIA (electricity rates), DOE/EPA (EV efficiency), AAA (gas prices).

How to Reduce Your Monthly EV Charging Cost
1. Time-of-Use (TOU) Rates
Many utilities offer lower electricity rates during off-peak hours (typically 11 PM – 6 AM). You could save 30–50% on your charging cost by setting your EV to charge overnight.
2. Home vs. Public Charging
Home charging is 2–3× cheaper than public charging. If you don't have a home charger, consider installing one — the upfront cost pays off quickly.
3. Utility Programs
Some utilities offer special EV charging plans or rebates:
- Tesla Electric: ~$15/month for unlimited overnight charging in select states.
- FPL (Florida): ~$31/month for unlimited off-peak charging.
- PG&E (California): EV2-A rate plan with off-peak rates as low as 11¢/kWh.
4. Drive Efficiently
Efficient driving (smooth acceleration, regenerative braking, moderate speeds) can improve your EV's efficiency by 10–20%, directly reducing your monthly cost.
