Model
Spt SD-6513SS
Rank #411 means 410 of the 709 dishwasher models we track cost less to run each year; the 16th efficiency percentile means it uses less energy for its size than 16% of those models.
What does the Spt SD-6513SS cost to run per year?
At about $45 a year, the Spt SD-6513SS lands in the middle third of dishwasher models we track on running cost, rank #411 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. Capacity-normalized, it ranks ahead of just 16% of dishwasher models we track, a clearly below-average result. This class has no published efficiency-factor figure beyond annual kWh itself, so at 10 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-6505** at $45/yr runs a little cheaper and the Spt SD-6513W 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 Spt SD-6513SS's $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

By the numbers
The Spt SD-6513SS 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 Spt SD-6513SS 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-6513SS 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 Spt SD-6513SS 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 Spt SD-6513SS uses 21.8% less energy.
What drives its running cost
At 10 place settings, the Spt SD-6513SS 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. 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-6513SS cheap to run?
Roughly, yes. Its $45/yr figure is close to the class median, ranking #411 of 709, neither a bargain nor a splurge on running cost.
How much does the Spt SD-6513SS 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 Spt SD-6513SS for its size?
16th percentile once size is factored in, a fairly typical result for the class.
