Model
Frigidaire FFBD1831US
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 Frigidaire FFBD1831US cost to run per year?
At $45 a year to run, the Frigidaire FFBD1831US sits close to the middle of its class on cost, ranking #379 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. Once capacity is factored in, its efficiency percentile of 7 is among the lowest in its class. 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 Frigidaire FFBD1831UB at $45/yr runs a little cheaper and the Frigidaire FFBD1831UW 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 Frigidaire FFBD1831US's $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

By the numbers
The Frigidaire FFBD1831US 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 Frigidaire FFBD1831US adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Frigidaire FFBD1831US 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 Frigidaire FFBD1831US 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 Frigidaire FFBD1831US uses 21.8% less energy.
What drives its running cost
At 8 place settings, the Frigidaire FFBD1831US is a small dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, and smaller dishwasher models generally cost less to run for the same job, all else being equal.
- 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 Frigidaire FFBD1831US 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 Frigidaire FFBD1831US 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 Frigidaire FFBD1831US for its size?
7th percentile once size is factored in, a fairly typical result for the class.
