Your EV's usable battery capacity.
Check your vehicle's specifications — this varies significantly by model, commonly ranging from about 40 to 100+ kWh.
Your home electricity rate.
Check a recent electric bill — some utilities offer a discounted off-peak or EV-specific rate for overnight charging.
Your vehicle's rated range on a full charge.
Use your EPA-rated range, or your own observed real-world range if it differs meaningfully.

How this was calculated
Formula source(s)
- Cost per full charge = battery capacity (kWh) x electricity rate ($/kWh); cost per mile = cost per full charge / miles of range per charge
Inputs used
- Battery Capacity (kWh)
- 75
- Electricity Rate ($/kWh)
- Miles of Range per Full Charge
- 250
What this calculation does not cover
- It prices the energy stored in the battery, not the energy the meter records. Onboard-charger and cable losses, battery thermal conditioning and cabin preconditioning all draw billed kWh this calculation ignores, so the real bill runs above the figure shown — more so in cold weather and on slow Level 1 charging.
- One flat rate per kWh is all it takes. Time-of-use bands, tiered block rates, standing or daily supply charges, demand charges, taxes and levies not already inside the rate you type, and any solar self-consumption or export credit are all outside the model.
- Range is whatever you type, held fixed. Cold weather, cabin heating, speed, terrain, load, tyres and pack degradation over the vehicle's life all move miles per charge, and there is no seasonal or degradation term here — the cost per mile is only as good as the range figure you enter.
- It assumes a single charge from empty to full. It does not model partial top-ups, a routine charge limit set below 100%, or a mix that includes public or DC fast charging with its own per-kWh premium, session fees and subscription plans.
- This is a cost estimate, not an electrical design. It says nothing about whether the circuit, cable, protective device or supply capacity can serve a charge point, and nothing about the added load on the existing service — sizing and protecting an EV charge point circuit is a separate calculation under the wiring rules in force, and the installation itself is regulated work in most jurisdictions.
