Model
Forno FDWBI8011-24
Rank #390 means 389 of the 709 dishwasher models we track cost less to run each year; the 84th efficiency percentile means it uses less energy for its size than 84% of those models.
What does the Forno FDWBI8011-24 cost to run per year?
At $45 a year to run, the Forno FDWBI8011-24 sits close to the middle of its class on cost, ranking #390 of 709 dishwasher models we track. 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. Efficiency-wise, once capacity is accounted for, it beats 84% of the class, a solidly strong result rather than a size-driven fluke. At 16 place settings, it is a large 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 Forno FDWBI8010-24*** at $45/yr runs a little cheaper and the Forno FDWBI8033-24 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 Forno FDWBI8011-24's $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

By the numbers
The Forno FDWBI8011-24 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 Forno FDWBI8011-24 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Forno FDWBI8011-24 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 Forno FDWBI8011-24 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 Forno FDWBI8011-24 uses 21.8% less energy.
What drives its running cost
At 16 place settings, the Forno FDWBI8011-24 is a large dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, and larger dishwasher models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light.
- 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 Forno FDWBI8011-24 cheap to run?
It is about average. At $45 a year it ranks #390 of 709 dishwasher models we track, close to the middle of its class on running cost.
How much does the Forno FDWBI8011-24 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 Forno FDWBI8011-24 for its size?
84th percentile once size is factored in, a fairly typical result for the class.
