How to use the EV Electricity Cost Calculator

  1. 1Enter monthly miles driven.
  2. 2Enter EV efficiency in miles per kWh (typically 3.0 to 4.2 mi/kWh).
  3. 3Enter residential electricity rate per kWh.
  4. 4Enter benchmark gasoline car MPG and local gas price to view savings.

How EV Electric Cost is Calculated

Monthly kWh needed = Monthly Miles / Efficiency. Cost = Monthly kWh × Electricity Rate.

Mathematical Formula
Monthly kWh = Miles / (mi/kWh) Monthly Electric Cost = Monthly kWh × Rate Gas Savings = (Miles / Gas MPG × Gas Price) - Monthly Electric Cost
Formula Variables & Logic

Reflects combined savings from electricity pricing vs gasoline.

Worked Example: Charging 1,000 Miles/Month at Home
Sample Calculation
Scenario: 1,000 miles/month in an EV getting 3.5 mi/kWh at $0.14/kWh, compared to a 30 MPG gas car at $3.50/gal.
Step-by-step breakdown
  1. 1Energy Used = 1,000 / 3.5 = 285.7 kWh
  2. 2EV Monthly Power Bill = 285.7 × $0.14 = $40.00
  3. 3Gas Car Cost = (1,000 / 30) × $3.50 = $116.67
  4. 4Net Monthly Fuel Savings = $116.67 - $40.00 = $76.67
Estimated Result
Monthly charging cost is $40.00 (Saves $76.67/month vs gasoline).

What affects EV Electric Cost results
