Model
Spt SD-2225**
Rank #11 means 10 of the 709 dishwasher models we track cost less to run each year; the 13th efficiency percentile means it uses less energy for its size than 13% of those models.
What does the Spt SD-2225** cost to run per year?
The Spt SD-2225** runs for about $29 a year, landing it in the very bottom slice of the cost table at rank #11 of 709 dishwasher models we track. It uses 30.2% less energy than the U.S. federal standard model in its class, which would cost about $41/yr to run, a saving of roughly $12 a year. Capacity-normalized, it ranks ahead of just 13% of dishwasher models we track, a clearly below-average result. This class has no published efficiency-factor figure beyond annual kWh itself, so at 6 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 Spt SD-2224** at $29/yr runs a little cheaper and the Miele G 5892 SCVi SL at $37/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 Spt SD-2225**'s $29/yr adds up to roughly $261 in electricity alone, before purchase price or repairs.

By the numbers
The Spt SD-2225** 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 $29/yr, here is what the Spt SD-2225** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Spt SD-2225** costs about $290. That is roughly $120 less than a standard model in its class, which would run closer to $410 over the same ten years.
How the Spt SD-2225** compares
The dishwasher class we track runs from $15 to $45 a year. At $29/yr, it runs about $15 a year cheaper than the class median of $44, and it is about $14 a year more than the cheapest dishwasher to run at $15. Against the US federal standard model for its class at about $41/yr, the Spt SD-2225** uses 30.2% less energy.
What drives its running cost
At 6 place settings, the Spt SD-2225** is a small dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture.
- 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 Spt SD-2225** cheap to run?
Yes. Its $29/yr running cost puts it at rank #11 of 709, below what most dishwasher models we track cost to run.
How much does the Spt SD-2225** cost per month?
About $2.4 a month, which is the $29 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: 155 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $29 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Spt SD-2225** for its size?
13th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
