Planning a road trip in your EV? This calculator estimates total charging costs and how many charging stops you’ll likely need along the way, based on your trip distance, your vehicle’s efficiency, and public charging prices — which are typically higher than home charging rates.
Enter your total trip distance, your EV’s efficiency, the public charging price per kWh you expect to pay, and your vehicle’s full-charge range. The calculator estimates your total energy needed, total charging cost, and how many charging stops to plan for.
FAQ
How much does it cost to charge an EV on a road trip?
Cost depends on trip distance, vehicle efficiency, and public charging rates, which are usually higher than home electricity prices. A 300-mile trip in an efficient EV using public fast chargers might cost around $25–35 in charging alone.
Why is public charging more expensive than home charging?
Public DC fast chargers involve higher infrastructure and maintenance costs, and many networks charge a premium for speed and convenience, unlike home charging where you pay standard residential electricity rates.
How many charging stops will I need on a road trip?
This depends on your vehicle’s full-charge range compared to your total trip distance. This calculator estimates stops assuming you start at 100% charge and recharge fully at each stop — actual stops may vary based on charger availability along your route.
Does this calculator account for charging speed or time?
No — this tool focuses on cost and stop count. Use the separate Charging Time Calculator to estimate how long each charging stop will take.
