Model
Koolatron KTUF59-W-H
Rank #115 means 114 of the 622 freezer models we track cost less to run each year; the 21st efficiency percentile means it uses less energy for its size than 21% of those models.
What does the Koolatron KTUF59-W-H cost to run per year?
The Koolatron KTUF59-W-H runs for about $52 a year, landing it near the bottom of the cost table at rank #115 of 622 freezer models we track. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $58/yr to run, a saving of roughly $6 a year. Its size-adjusted efficiency percentile of 21 suggests its capacity is doing more work than its efficiency to keep the headline cost down. This class has no published efficiency-factor figure beyond annual kWh itself, so at 5.9 cu ft (the class spans 1.1 to 23), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Danby DUFM060B1WDB at $52/yr runs a little cheaper and the Magic Chef HMUF6WE at $52/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A freezer typically stays in service for somewhere around 14 years; over that span, the Koolatron KTUF59-W-H's $52/yr adds up to roughly $728 in electricity alone, before purchase price or repairs.

By the numbers
The Koolatron KTUF59-W-H 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 $52/yr, here is what the Koolatron KTUF59-W-H adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Koolatron KTUF59-W-H costs about $520. That is roughly $60 less than a standard model in its class, which would run closer to $580 over the same ten years.
How the Koolatron KTUF59-W-H compares
The freezer class we track runs from $25 to $120 a year. At $52/yr, it runs about $23 a year cheaper than the class median of $75, and it is about $27 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $58/yr, the Koolatron KTUF59-W-H uses 11% less energy.
What drives its running cost
At 5.9 cu ft, the Koolatron KTUF59-W-H is a small freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, and smaller freezer models generally cost less to run for the same job, all else being equal.
- Interior volume. As with refrigerators, more cubic feet of frozen storage generally means a bigger compressor and a higher annual energy figure.
- Insulation and defrost type. Better-insulated cabinets lose less cold to the surrounding room, and frost-free (automatic-defrost) freezers run a periodic heating element that a manual-defrost model does not.
- Chest vs upright design. Door orientation affects how much cold air escapes per opening: top-opening chest designs generally hold cold better than front-opening upright ones.
Common questions
Is the Koolatron KTUF59-W-H cheap to run?
Yes. Its $52/yr running cost puts it at rank #115 of 622, below what most freezer models we track cost to run.
How much does the Koolatron KTUF59-W-H cost per month?
About $4.35 a month, which is the $52 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: 281 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $52 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Koolatron KTUF59-W-H for its size?
21st 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.
