Model
Ikea 705.910.18
Rank #377 means 376 of the 709 dishwasher models we track cost less to run each year; the 56th efficiency percentile means it uses less energy for its size than 56% of those models.
What does the Ikea 705.910.18 cost to run per year?
Ranking #377 of 709, the Ikea 705.910.18 runs at roughly $45 a year, neither the cheapest nor the priciest in its class. 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. Normalized for capacity, it beats 56% of dishwasher models we track, an average result for the class. At 14 place settings, it is a mid-size 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 Ikea 005.876.23 at $45/yr runs a little cheaper and the Ikea FL�BODA 305.911.57 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 Ikea 705.910.18's $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

By the numbers
The Ikea 705.910.18 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 Ikea 705.910.18 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Ikea 705.910.18 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 Ikea 705.910.18 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 Ikea 705.910.18 uses 21.8% less energy.
What drives its running cost
At 14 place settings, the Ikea 705.910.18 is a mid-size dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone.
- 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 Ikea 705.910.18 cheap to run?
It is about average. At $45 a year it ranks #377 of 709 dishwasher models we track, close to the middle of its class on running cost.
