Model
Whirlpool WZF57R16F***
Rank #327 means 326 of the 622 freezer models we track cost less to run each year; the 72nd efficiency percentile means it uses less energy for its size than 72% of those models.
What does the Whirlpool WZF57R16F*** cost to run per year?
At about $78 a year, the Whirlpool WZF57R16F*** lands in the middle third of freezer models we track on running cost, rank #327 of 622. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $86/yr to run, a saving of roughly $8 a year. Its size-adjusted efficiency percentile of 72 is comfortably above the class median. This class has no published efficiency-factor figure beyond annual kWh itself, so at 15.7 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 Thermador T18IF901SP at $78/yr runs a little cheaper and the Fisher & Paykel RS30F*E* at $79/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 Whirlpool WZF57R16F***'s $78/yr adds up to roughly $1092 in electricity alone, before purchase price or repairs.
By the numbers
The Whirlpool WZF57R16F*** 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 $78/yr, here is what the Whirlpool WZF57R16F*** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Whirlpool WZF57R16F*** costs about $780. That is roughly $80 less than a standard model in its class, which would run closer to $860 over the same ten years.
How the Whirlpool WZF57R16F*** compares
The freezer class we track runs from $25 to $120 a year. At $78/yr, it runs about $3 a year above the class median of $75, and it is about $53 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $86/yr, the Whirlpool WZF57R16F*** uses 10% less energy.
What drives its running cost
At 15.7 cu ft, the Whirlpool WZF57R16F*** is a mid-size freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, 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.
- 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 Whirlpool WZF57R16F*** cheap to run?
Roughly, yes. Its $78/yr figure is close to the class median, ranking #327 of 622, neither a bargain nor a splurge on running cost.
How much does the Whirlpool WZF57R16F*** cost per month?
About $6.48 a month, which is the $78 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: 419 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $78 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Whirlpool WZF57R16F*** for its size?
72nd percentile once size is factored in, a fairly typical result for the class.
