How to use this calculator
- Enter the total trip distance in miles.
- Set your EV's efficiency in miles per kWh.
- Enter the mix of home vs public charging you expect on the trip.
- Set the public fast charging rate (DC fast chargers typically $0.28–0.45/kWh).
- See total trip charging cost and compare to the equivalent gas car cost.
Understanding your results
How road trip charging cost is calculated: Total kWh needed = trip miles ÷ EV efficiency. That kWh is split between public fast charging and home charging based on your input percentage. EV total cost = (public kWh × fast charge rate) + (home kWh × home rate). A 500-mile trip in a 3.5 mi/kWh vehicle needs 143 kWh. At 80% public charging ($0.35/kWh) and 20% home ($0.14/kWh): (114 × 0.35) + (29 × 0.14) = $40 + $4 = $44 total — vs $55 in gas for a 32 MPG car at $3.50/gallon.
Public vs home charging cost gap: DC fast charging at Tesla Supercharger or Electrify America averages $0.28–$0.45/kWh in 2026 — 2–3× home rates. On a 1,000-mile road trip, the difference between 100% public charging ($0.35/kWh) and 100% home charging ($0.14/kWh) is roughly $60 — significant but still much less than gasoline for most comparable vehicles.
Charging stop planning: Plan stops every 150–200 miles, targeting 20–80% state of charge to use the fastest part of the charging curve. Most modern EVs charge fastest between 10–50% battery. Arriving at a charger with 15–20% remaining and stopping at 80% minimises time per stop. Apps like A Better Route Planner (ABRP) optimise stop locations automatically based on your vehicle’s charging curve.
Comparing EV vs gas for road trips: The EV charging cost advantage narrows on road trips vs daily driving because public charging rates are higher than home rates. For a 500-mile trip, an EV using 80% public charging typically costs $35–$55 — comparable to or slightly cheaper than gas. The real advantage returns once you’re back home charging overnight.
