Planning estimate. Your utility’s tariff, taxes, tiers and adjustments control the actual bill.

FORMULAGrid kWh = miles × kWh per 100 miles ÷ 100 ÷ (1 − charging loss)
IMPORTANT LIMIT

Time-of-use rates, charging losses, weather and battery conditioning affect actual cost.

HOW TO USE IT

Copy the bill’s units first.

Match every field to the unit printed on your statement. Use the current billing period, preserve fixed charges, and compare a similar number of service days.

For a stronger estimate

  1. Use the exact rate from your bill instead of a reference average.
  2. Keep taxes, credits and past-due balances separate.
  3. Check tiers or time-of-use windows in the utility tariff.
