Model
Whirlpool WZC3209LW
Rank #25 means 24 of the 622 freezer models we track cost less to run each year; the 98th efficiency percentile means it uses less energy for its size than 98% of those models.
What does the Whirlpool WZC3209LW cost to run per year?
Almost nothing we track in this class costs less to run than the Whirlpool WZC3209LW: about $37 a year, rank #25 of 622. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $42/yr to run, a saving of roughly $5 a year. Normalized for capacity, it ranks ahead of 98% of freezer models we track on efficiency, an exceptional showing for the class. At 9 cu ft, it is a small freezer for the class, which runs 1.1 to 23 cu ft; size and efficiency are the two levers behind the figure above, and this dataset does not carry a separate efficiency-factor column for this class.
Immediately around it on the leaderboard, the Master Chef 043-0293-0 at $36/yr runs a little cheaper and the Danby DCF100A5WDB at $39/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 WZC3209LW's $37/yr adds up to roughly $518 in electricity alone, before purchase price or repairs.
By the numbers
The Whirlpool WZC3209LW 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 $37/yr, here is what the Whirlpool WZC3209LW 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 WZC3209LW costs about $370. That is roughly $50 less than a standard model in its class, which would run closer to $420 over the same ten years.
How the Whirlpool WZC3209LW compares
The freezer class we track runs from $25 to $120 a year. At $37/yr, it runs about $38 a year cheaper than the class median of $75, and it is about $12 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $42/yr, the Whirlpool WZC3209LW uses 10% less energy.
What drives its running cost
At 9 cu ft, the Whirlpool WZC3209LW 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. Cubic feet of frozen storage is the first lever behind a freezer's running cost, ahead of insulation or defrost type.
- Insulation and defrost type. Two freezers of the same size can differ meaningfully on running cost based on insulation quality and whether they run an automatic-defrost heater.
- Chest vs upright design. Chest freezers open from the top, so cold air, which sinks, stays inside when the lid opens; upright freezers lose more cold air per door opening for a similar capacity.
Common questions
Is the Whirlpool WZC3209LW cheap to run?
Yes, relatively. At $37 a year it ranks #25 of 622 freezer models we track, in the cheaper part of its class to run.
How much does the Whirlpool WZC3209LW cost per month?
Roughly $3.11/mo, spreading the $37/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 201 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $37 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Whirlpool WZC3209LW for its size?
98th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
