EV Charging Network Cost
Cost a long EV trip mixing fast chargers and home power.
About EV Charging Network Cost
Split the trip's total energy by what is bought on fast chargers versus at home, then price each share at its own rate. Public fast chargers can cost triple the home rate, so the premium line is what an all-home itinerary would save on the same trip.
Formula
EV Charging Network Cost
Trip cost = fast energy x fast rate + home energy x home rate
- fast rate
- Per-kWh price posted by DC fast chargers

Assumptions and limits
- The result is derived only from the 5 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is EV Charging Network Cost calculated?
Trip cost = fast energy x fast rate + home energy x home rate Split the trip's total energy by what is bought on fast chargers versus at home, then price each share at its own rate.
Why does EV Charging Network Cost matter?
Public fast chargers can cost triple the home rate, so the premium line is what an all-home itinerary would save on the same trip.
What values do I need to enter?
This calculator takes 5 inputs: Round-trip miles, EV efficiency, Fast-charged share, Fast charger rate, Home rate. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
