Know exactly what you spend on fuel

Unlike gasoline, electricity rates vary by time of day, provider, and charging method. This tool makes the real cost transparent.

Home vs. public rates

Public DCFC rates can be 2–4× higher than home electricity. Mixing the two in your cost model gives a realistic picture of monthly spend.

🔋

Charger efficiency losses

Every charger wastes some energy as heat. Level 2 units lose roughly 5%, while DC fast chargers can lose 10–15% depending on power level.

📊

Cost per mile comparison

The cost-per-mile figure lets you compare directly with gasoline vehicles and assess the actual financial advantage of your EV.
