EV Charging Cost Formula — How the Calculation Works
The calculator uses a straightforward formula to estimate your charging costs. Here's the math behind it.
Formula:
Charging Cost = (Battery Capacity × Charge Percentage) × Electricity Rate ÷ Charging Efficiency
- Battery Capacity — usable battery size in kWh (e.g., 75 kWh for a Tesla Model Y)
- Charge Percentage — fraction of battery you're adding (e.g., from 20% to 80% = 0.60)
- Electricity Rate — cost per kWh (e.g., $0.15 / kWh)
- Charging Efficiency — typical values: 85% (Level 1), 90% (Level 2), 92% (DC fast)
Example calculation
Scenario: You own a Tesla Model 3 with a 60 kWh battery. You charge from 20% to 80% (60% of battery = 36 kWh) at home using a Level 2 charger. Your electricity rate is $0.14 / kWh, and charging efficiency is 90%.
Cost = (60 kWh × 0.60) × $0.14 ÷ 0.90 = 36 × $0.14 ÷ 0.90 = $5.60
So a 20‑80% charge costs about $5.60. At 4 miles per kWh, that's roughly 3.9¢ per mile — much cheaper than gas.
8 Key Factors That Affect Your EV Charging Cost
Your actual charging cost depends on several variables. Understanding these factors helps you optimize your charging strategy and save money.
| Factor | Impact on Cost |

| 5‑year fuel savings | $3,600 – $9,000+ | |
Expert Tips to Lower Your EV Charging Costs
- Charge during off‑peak hours. Most utilities offer lower rates between 11 pm and 6 am. Use your vehicle's scheduled charging feature to take advantage of TOU rates.
- Install a Level 2 home charger. Level 2 charging is more efficient (90‑92%) than Level 1 (85%) and charges your EV 5‑7× faster.
- Check for EV‑specific utility plans. Many utilities offer special EV rates with even lower off‑peak prices. Some even offer free charging during certain hours.
- Use public charging strategically. Public DC fast charging is convenient but expensive. Use it only for road trips or when you need a quick top‑up. For daily charging, stick to home or workplace charging.
- Don't overcharge. Charging to 100% regularly is unnecessary for daily driving and can degrade your battery. Keep your charge between 20% and 80% for daily use.
- Take advantage of incentives. Federal, state, and local incentives can offset the cost of home charger installation and even reduce your electricity bill.
