Summit DW184BADA: running cost
At 234 kWh/yr, the Summit DW184BADA's ENERGY STAR certification puts it about average for its category to run against every other certified dishwasher.
That $44 is priced at 18.8¢/kWh, the average of all 51 state rates this site tracks. Your own state's rate is one click away.
Efficient, or not, for a dishwasher
The category average is 232 kWh/yr; this model runs 0.9% above it, ranking 265 of 737 dishwashers tracked here for running cost. That average is drawn from all 737 dishwashers ENERGY STAR currently certifies, not an outside number, a $0/year gap from this model at the national rate. Full sourcing is in the sourcing notes.
Right next to it on the list
A rank or two either side of the Summit DW184BADA: Summit DW184B ($44/yr, 234 kWh/yr), then Summit DW185SS ($44/yr, 234 kWh/yr).
Within the Summit lineup
Ranked 13 of Summit's 33 certified dishwashers, this sits between the DW18SS4 ($41/yr, the brand's cheapest) and the LDW24WA ($44/yr, its priciest).
What this adds up to over time
9 years is NAHB's typical service life for this category; at $44/year, the Summit DW184BADA adds up to about $396 in electricity over that span.
Weighing a replacement
Efficient as certified dishwashers go, $44/year is a reasonable baseline if you're comparing what else is on the market.

If you're keeping it
The Summit DW184BADA already costs $44/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
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 Dishwasher category page shows all 737 dishwashers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
