Model
Bosch SHX78CC5UC
Rank #384 means 383 of the 709 dishwasher models we track cost less to run each year; the 64th efficiency percentile means it uses less energy for its size than 64% of those models.
What does the Bosch SHX78CC5UC cost to run per year?
The Bosch SHX78CC5UC costs about $45 a year to run, a fairly typical figure for the class; it ranks #384 of 709. 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. Size-adjusted, this model beats 64% of dishwasher models we track on efficiency, better than most of its class. This class has no published efficiency-factor figure beyond annual kWh itself, so at 15 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 SHX65CM** at $45/yr runs a little cheaper and the Bosch SHX78CM** 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 Bosch SHX78CC5UC's $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

By the numbers
The Bosch SHX78CC5UC 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 Bosch SHX78CC5UC 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 SHX78CC5UC 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 Bosch SHX78CC5UC 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 Bosch SHX78CC5UC uses 21.8% less energy.
What drives its running cost
At 15 place settings, the Bosch SHX78CC5UC is a mid-size dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone.
- 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 SHX78CC5UC cheap to run?
Roughly, yes. Its $45/yr figure is close to the class median, ranking #384 of 709, neither a bargain nor a splurge on running cost.
How much does the Bosch SHX78CC5UC cost per month?
About $3.71 a month, which is the $45 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: 240 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $45 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Bosch SHX78CC5UC for its size?
64th percentile once size is factored in, a fairly typical result for the class.
