EV Charging in Missouri: What the Numbers Mean
Missouri's residential electricity rate is 12.3¢/kWh — 3.8¢ below the national average of 16.1¢/kWh, which works in EV owners' favor. At that rate, a typical EV (3.5 mi/kWh) costs $422/year to charge at home for 12,000 miles.
Compared to a 30 MPG gas car at $2.92/gal ($1168/year for the same miles), EV home charging saves $746/year — $3,730 over 5 years, before incentives.
Home Charging vs Public Charging in Missouri
The biggest driver of EV cost is where you charge. Home charging at 12.3¢/kWh is always the cheapest option. Public Level 2 stations average around 30.8¢/kWh — 2.5x more expensive. DC fast chargers run about 34.2¢/kWh. Tesla Superchargers in Missouri are estimated at 26.8¢–33.3¢/kWh depending on membership.
Most EV owners do 80%+ of their charging at home overnight. If you don't have home charging access, the economics shift significantly — charging entirely at public DC fast chargers would cost $1173/year in Missouri, narrowing the gap with gas considerably.
