Model
Bosch SHX78DC**
Rank #62 means 61 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 SHX78DC** cost to run per year?
The Bosch SHX78DC** runs for about $40 a year, landing it near the bottom of the cost table at rank #62 of 709 dishwasher models we track. It uses 30% 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 Bosch SHV41DB3N at $40/yr runs a little cheaper and the Smeg DW8630 at $41/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 SHX78DC**'s $40/yr adds up to roughly $360 in electricity alone, before purchase price or repairs.
By the numbers
The Bosch SHX78DC** 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 SHX78DC** 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 SHX78DC** 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 SHX78DC** 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 SHX78DC** uses 30% less energy.
What drives its running cost
At 16 place settings, the Bosch SHX78DC** is a large dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up.
- 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 SHX78DC** cheap to run?
Yes. Its $40/yr running cost puts it at rank #62 of 709, below what most dishwasher models we track cost to run.
How much does the Bosch SHX78DC** cost per month?
About $3.33 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: 215 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 SHX78DC** 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.
