EV Road Trip Cost Calculator 2026: Charging vs Gas
Estimate the total charging cost of an EV road trip in 2026. Mix home and DC fast charging for any distance and compare it with fuel for a gas car.

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 ($0.182/kWh, the US average): 114 kWh × $0.35 + 29 kWh × $0.182 ≈ $45 total — vs $51 in gas for a 32 MPG car at $3.25/gallon.
Public vs home charging cost gap: DC fast charging at Tesla Supercharger or Electrify America averages $0.28–$0.45/kWh in 2026 — roughly 1.5–2.5× the US average home rate. On a 1,000-mile road trip, the difference between 100% public charging ($0.35/kWh) and 100% home charging ($0.182/kWh) is roughly $48 — 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% minimizes time per stop. Apps like A Better Route Planner (ABRP) optimize stop locations automatically based on your vehicle’s charging curve.
Comparing EV vs gas for road trips: The EV cost advantage narrows on road trips because fast-charging prices are higher than home rates. In the default example, a 500-mile trip with 80% fast charging costs about $45 versus about $51 of gas; at $0.45/kWh fast charging the EV costs about $57. The larger advantage returns once you’re back home charging overnight.
2026 incentive note: Federal EV purchase credits (§30D, §25E) ended for vehicles acquired after September 30, 2025, and the §30C charger credit ended for chargers placed in service after June 30, 2026. None of them affect trip charging costs, which this calculator models directly. This is not tax advice.
