Model
Honeywell HDS18*
Rank #198 means 197 of the 709 dishwasher models we track cost less to run each year; the 10th efficiency percentile means it uses less energy for its size than 10% of those models.
What does the Honeywell HDS18* cost to run per year?
At $43 a year to run, the Honeywell HDS18* runs cheaper than most models in its class, ranking #198 of 709 dishwasher models we track. It uses 23.8% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $14 a year. Its 10th size-adjusted efficiency percentile is well below the class median, worth weighing against the raw cost figure above. At 8 place settings, it is a small dishwasher for the class, which runs 2 to 18 place settings; size and efficiency are the two levers behind the figure above, and this dataset does not carry a separate efficiency-factor column for this class.
Immediately around it on the leaderboard, the Ge Profile PBT865S*P*** at $43/yr runs a little cheaper and the Honeywell HDS18SS at $43/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A dishwasher typically stays in service for somewhere around 9 years; over that span, the Honeywell HDS18*'s $43/yr adds up to roughly $387 in electricity alone, before purchase price or repairs.

By the numbers
The Honeywell HDS18* normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $43/yr, here is what the Honeywell HDS18* adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Honeywell HDS18* costs about $430. That is roughly $140 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Honeywell HDS18* compares
The dishwasher class we track runs from $15 to $45 a year. At $43/yr, it runs about $1 a year cheaper than the class median of $44, and it is about $28 a year more than the cheapest dishwasher to run at $15. Against the US federal standard model for its class at about $57/yr, the Honeywell HDS18* uses 23.8% less energy.
What drives its running cost
At 8 place settings, the Honeywell HDS18* is a small dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture.
- Place-setting capacity. A larger dishwasher heats more water per cycle, so bigger capacity generally means a higher annual energy figure, independent of how efficient the unit is.
- Water heating. The booster heater that brings water up to sanitizing temperature is usually the single largest electrical load in a dishwasher's cycle.
- Cycle length and drying method. Cycle selection, eco versus heavy, air-dry versus heated-dry, moves real running cost more than most owners realize for a given capacity.
Common questions
Is the Honeywell HDS18* cheap to run?
Yes, relatively. At $43 a year it ranks #198 of 709 dishwasher models we track, in the cheaper part of its class to run.
How much does the Honeywell HDS18* cost per month?
Roughly $3.62/mo, spreading the $43/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 234 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $43 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Honeywell HDS18* for its size?
10th percentile once size is factored in, a fairly typical result for the class.
