Model
Aeg F8242FI-18
Rank #175 means 174 of the 709 dishwasher models we track cost less to run each year; the 21st efficiency percentile means it uses less energy for its size than 21% of those models.
What does the Aeg F8242FI-18 cost to run per year?
At about $43 a year, the Aeg F8242FI-18 undercuts most dishwasher models we track on running cost, rank #175 of 709. 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 size-adjusted efficiency percentile of 21 suggests its capacity is doing more work than its efficiency to keep the headline cost down. This class has no published efficiency-factor figure beyond annual kWh itself, so at 10 place settings (the class spans 2 to 18), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Aeg F8242FI at $43/yr runs a little cheaper and the Aeg F8642FI 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 Aeg F8242FI-18's $43/yr adds up to roughly $387 in electricity alone, before purchase price or repairs.

By the numbers
The Aeg F8242FI-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 $43/yr, here is what the Aeg F8242FI-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 Aeg F8242FI-18 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 Aeg F8242FI-18 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 Aeg F8242FI-18 uses 23.8% less energy.
What drives its running cost
At 10 place settings, the Aeg F8242FI-18 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. Place-setting capacity is the main driver of how much water a cycle has to heat, and heating that water is most of a dishwasher's electricity use.
- Water heating. Most dishwashers have a booster heater that raises incoming water to sanitizing temperature; this heating step, not the pump or motor, accounts for most of a cycle's electricity use.
- Cycle length and drying method. Heavy or sanitize cycles run longer and hotter than a normal or eco cycle, and heated-dry options cost more to run than air-dry or condensation drying.
Common questions
Is the Aeg F8242FI-18 cheap to run?
Yes. Its $43/yr running cost puts it at rank #175 of 709, below what most dishwasher models we track cost to run.
How much does the Aeg F8242FI-18 cost per month?
About $3.62 a month, which is the $43 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 234 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $43 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Aeg F8242FI-18 for its size?
21st percentile once size is factored in, a fairly typical result for the class.
