Efficient, or not, for a washing machine
The category average is 123 kWh/yr; this model runs 70.7% above it, ranking 367 of 398 washing machines tracked here for running cost. That average is drawn from all 398 washing machines ENERGY STAR currently certifies, not an outside number, a $16/year gap from this model at the national rate.

Right next to it on the list
A rank or two either side of the LG WT8405C: LG WT7155C ($38/yr, 200 kWh/yr), then Midea MLTW53A5CCG ($40/yr, 213 kWh/yr).
Within the LG lineup
Ranked 86 of LG's 93 certified washing machines, this sits between the WM3420C ($15/yr, the brand's cheapest) and the WT7485C ($41/yr, its priciest).
LG WT8405C over 10 years
NAHB's Study of Life Expectancy of Home Components puts a typical washing machine's service life at 10 years; run the LG WT8405C that long and it costs about $395 in electricity, on top of whatever it cost to buy.
Shopping for a new one
The LG WT8405C runs above its category average. If the washing machine you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $39/year every year.
Worth comparing a few current certified models before deciding.
If you're keeping it
$39/year to run is the predictable cost of the LG WT8405C; a protection plan covers the unpredictable one, a repair bill.
Where this number comes from
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Washing Machine category page shows all 398 washing machines ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
