Bosch DWHD661EFP
Rank #60 means 59 of the 709 dishwasher models we track cost less to run each year; the 96th efficiency percentile means it uses less energy for its size than 96% of those models.
What does the Bosch DWHD661EFP cost to run per year?
Rank #60 of 709 puts the Bosch DWHD661EFP among the cheapest dishwasher models we track to keep running, at roughly $40 a year. It uses 30.6% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $17 a year. Its 96th size-adjusted efficiency percentile puts it in a small top tier of the class once capacity stops flattering the comparison. This class has no published efficiency-factor figure beyond annual kWh itself, so at 16 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 Miele G 7986 SCVi at $39/yr runs a little cheaper and the Bosch SHV41DB3N at $40/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 Bosch DWHD661EFP's $40/yr adds up to roughly $360 in electricity alone, before purchase price or repairs.
By the numbers
The Bosch DWHD661EFP 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 $40/yr, here is what the Bosch DWHD661EFP adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Bosch DWHD661EFP costs about $400. That is roughly $170 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Bosch DWHD661EFP compares
The dishwasher class we track runs from $15 to $45 a year. At $40/yr, it runs about $4 a year cheaper than the class median of $44, and it is about $25 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 Bosch DWHD661EFP uses 30.6% less energy.
What drives its running cost
At 16 place settings, the Bosch DWHD661EFP is a large dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, among dishwasher models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal.
- 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 Bosch DWHD661EFP cheap to run?
Yes. Its $40/yr running cost puts it at rank #60 of 709, below what most dishwasher models we track cost to run.
How much does the Bosch DWHD661EFP cost per month?
About $3.29 a month, which is the $40 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: 213 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $40 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Bosch DWHD661EFP for its size?
96th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
