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) × 19.29¢/kWh = $55/month
- Rate in Delaware: 19.29¢/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 $95/month here. Run your own numbers in the calculator.
How Delaware compares
Delaware's 19.29¢/kWh is 5% above the national average of 18.34¢/kWh (June 2026). Over the past 12 months it has averaged 17.80¢/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.
