How we get these numbers

We use the same formula as our cost article: monthly miles divided by efficiency, times the electricity rate.

(1,000 mi ÷ 3.5 mi/kWh) × 35.85¢/kWh = $102/month

  • Rate in Maryland: 35.85¢/kWh (residential average)
  • Efficiency: 3.5 mi/kWh, a typical passenger EV
  • Driving: 1,000 miles/month, near the US average

Figures assume no charging loss, to match the article and keep the math clear. Real-world AC charging adds roughly 10%. For the same miles, a 30 mpg gas car at $4.50/gallon (Q2 2026) would run about $150/month, so charging at home saves roughly $48/month here. Run your own numbers in the calculator.

How Maryland compares

Maryland35.85¢U.S. average18.83¢

Maryland's 35.85¢/kWh is 90% above the national average of 18.83¢/kWh (March 2026). Over the past 12 months it has averaged 21.40¢/kWh, so a single month is not an outlier.

Rates are a residential blended average. Your own bill depends on your utility and rate plan; many utilities offer cheaper overnight time-of-use rates that cut EV charging costs further. See every state's rate.
