EV Charging Cost Calculator
Enter your EV's battery capacity (kWh), your electricity rate ($/kWh) and your car's real-world efficiency (miles per kWh, or use a typical default). This tool multiplies battery size by your electricity rate for a real 'cost to fully charge' figure, divides by range for a real cost-per-mile, and lets you enter any trip distance for a real trip cost — the same honest arithmetic as a gas cost calculator, just using electricity instead of gasoline.
It also compares home charging (your entered household rate) against a typical public fast-charging rate, since DC fast chargers commonly cost 2-3x more per kWh than charging at home — a real gap that matters for anyone deciding where to charge.
Key features
Real cost to fully charge
Battery size × your electricity rate, no guessing.
Cost per mile
Based on your car's real efficiency in miles per kWh.
Any trip distance
Enter a trip length for an exact cost, with a round-trip toggle.
Home vs public charging
See the real cost gap between charging at home and at a fast charger.
How to use it
- Enter your battery size in kWh.
- Enter your home electricity rate per kWh.
- Enter your car's efficiency in miles per kWh (a typical default is provided).
- Enter a trip distance to see the real cost for that trip.
Worked example
Example
60 kWh battery, $0.16/kWh, 3.5 mi/kWh → about $9.60 to fully charge, roughly $0.046 per mile, about $4.60 for a 100-mile trip at home.

Tips for the best results
- Use your actual last electricity bill's per-kWh rate for the most accurate home-charging cost.
- Real-world efficiency is usually a bit lower than the EPA-rated number, especially in cold weather or highway driving — adjust the efficiency field down if needed.
- Public fast chargers often bill per minute instead of per kWh; treat the public-charging comparison here as an estimate.
Common mistakes to avoid
- Using the EPA-rated efficiency instead of your car's real observed efficiency, which tends to run a bit lower in practice.
- Forgetting that public fast-charging is usually priced higher per kWh than home charging.
- Assuming charging losses are zero — a small percentage of energy is lost during charging, which this simple model doesn't separately subtract.

Frequently asked questions
How is the cost to fully charge calculated?
Battery size in kWh × your entered electricity rate in $/kWh — real, direct arithmetic.
Why is public charging more expensive?
DC fast chargers have higher equipment and operating costs, so networks commonly charge 2-3x a typical home electricity rate; the exact rate varies by network and location, so this uses a stated typical reference rate.
Does this account for charging losses?
No, it's a simplified model based on energy delivered to the battery at your stated efficiency; real efficiency numbers you enter already reflect typical real-world driving, which partly absorbs this.
What's a typical EV efficiency?
Most EVs today get roughly 3-4 miles per kWh; smaller or more efficient models can exceed 4, and larger SUVs or trucks can be under 2.5 — check your vehicle's EPA rating as a starting point.
Is my data stored?
