Model
Insignia NS-UZ70WH4
Rank #126 means 125 of the 622 freezer models we track cost less to run each year; the 26th efficiency percentile means it uses less energy for its size than 26% of those models.
What does the Insignia NS-UZ70WH4 cost to run per year?
Ranking #126 of 622, the Insignia NS-UZ70WH4 is in the cheaper half of its class to run, at about $55 a year. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $62/yr to run, a saving of roughly $7 a year. Adjusted for size, it is only more efficient than 26% of freezer models we track, so part of its running cost comes from its capacity rather than efficiency alone. At 7 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 Insignia NS-UZ70WH27-C at $55/yr runs a little cheaper and the Insignia NS-UZ70WH4-C at $55/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 Insignia NS-UZ70WH4's $55/yr adds up to roughly $770 in electricity alone, before purchase price or repairs.

By the numbers
The Insignia NS-UZ70WH4 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 $55/yr, here is what the Insignia NS-UZ70WH4 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Insignia NS-UZ70WH4 costs about $550. That is roughly $70 less than a standard model in its class, which would run closer to $620 over the same ten years.
How the Insignia NS-UZ70WH4 compares
The freezer class we track runs from $25 to $120 a year. At $55/yr, it runs about $20 a year cheaper than the class median of $75, and it is about $30 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $62/yr, the Insignia NS-UZ70WH4 uses 11% less energy.
What drives its running cost
At 7 cu ft, the Insignia NS-UZ70WH4 is a small freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture.
- 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 Insignia NS-UZ70WH4 cheap to run?
Yes, relatively. At $55 a year it ranks #126 of 622 freezer models we track, in the cheaper part of its class to run.
How much does the Insignia NS-UZ70WH4 cost per month?
Roughly $4.58/mo, spreading the $55/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 296 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $55 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Insignia NS-UZ70WH4 for its size?
26th percentile once size is factored in, a fairly typical result for the class.
