Model
Hamilton Beach HBDW1922
Rank #379 means 378 of the 709 dishwasher models we track cost less to run each year; the 7th efficiency percentile means it uses less energy for its size than 7% of those models.
What does the Hamilton Beach HBDW1922 cost to run per year?
Do the math and the Hamilton Beach HBDW1922's $45/yr puts it at rank #379 of 709, right around the class average. It uses 21.8% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $12 a year. Adjusted for size, it is only more efficient than 7% of dishwasher models we track, so its headline cost is mostly a function of its capacity rather than efficiency. 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 Hamilton Beach HBDW1809-B-WHITE at $45/yr runs a little cheaper and the Heynemo ZDW001BK-11-HM at $45/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 Hamilton Beach HBDW1922's $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

By the numbers
The Hamilton Beach HBDW1922 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 $45/yr, here is what the Hamilton Beach HBDW1922 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Hamilton Beach HBDW1922 costs about $450. That is roughly $120 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Hamilton Beach HBDW1922 compares
The dishwasher class we track runs from $15 to $45 a year. At $45/yr, it runs about $1 a year above the class median of $44, and it is about $30 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 Hamilton Beach HBDW1922 uses 21.8% less energy.
What drives its running cost
At 8 place settings, the Hamilton Beach HBDW1922 is a small dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- 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 Hamilton Beach HBDW1922 cheap to run?
It is about average. At $45 a year it ranks #379 of 709 dishwasher models we track, close to the middle of its class on running cost.
How much does the Hamilton Beach HBDW1922 cost per month?
Roughly $3.71/mo, spreading the $45/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 240 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $45 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Hamilton Beach HBDW1922 for its size?
7th percentile once size is factored in, a fairly typical result for the class.
