Over the last 24 months Washington was cheapest in winter and most expensive in spring: January 2025 at 11.8¢/kWh and May 2026 at 14.9¢/kWh, which moves the Nissan Leaf's monthly charging cost between $33 and $42. The latest published month, August 2026, came in at 14.6¢/kWh, 3% above the 12-month average.

At 27.8 kWh per 100 miles, the 2026 Nissan Leaf 75 kWh (18-in steel wheels) is among the most efficient EVs EPA has rated for 2026: it uses less energy than 93% of the 321 2026 EV versions tested.

Across all 3 trims of the 2026 Leaf, cost per 100 miles in Washington ranges from $3.95 for the 75 kWh (18-in steel wheels) to $4.65 for the 75 kWh (19-in wheels), a difference of $85 a year at 1,016 miles a month.

EPA estimates 12 hours to charge the Leaf 75 kWh (18-in steel wheels) from empty on a 240-volt Level 2 home charger, longer than a typical night, though a full charge is rarely needed. At 1,016 miles a month (about 33 miles a day), a day's driving takes roughly 1.5 hours on a Level 2 charger.

Electricity would have to cost more than 54.5¢/kWh, 3.8 times Washington's rate, before the Nissan Leaf cost more per mile than the 2027 Nissan Kicks FWD. Put the other way, gas would have to fall below $1.22 a gallon.

Gas costs use EIA's Washington retail average for regular gasoline ($4.70 a gallon over the same 12 months, 30% above the U.S. average of $3.61) and the 2027 Nissan Kicks FWD's EPA rating of 31 mpg combined.
