Model
Insignia NS-UZ70WH27-C
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-UZ70WH27-C cost to run per year?
At about $55 a year, the Insignia NS-UZ70WH27-C undercuts most freezer models we track on running cost, rank #126 of 622. 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. Capacity-normalized, it ranks ahead of just 26% of freezer models we track, a soft spot worth weighing against the dollar figure. This class has no published efficiency-factor figure beyond annual kWh itself, so at 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 Insignia NS-UZ70WH27 at $55/yr runs a little cheaper and the Insignia NS-UZ70WH4 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-UZ70WH27-C's $55/yr adds up to roughly $770 in electricity alone, before purchase price or repairs.

By the numbers
The Insignia NS-UZ70WH27-C 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-UZ70WH27-C 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-UZ70WH27-C 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-UZ70WH27-C 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-UZ70WH27-C uses 11% less energy.
What drives its running cost
At 7 cu ft, the Insignia NS-UZ70WH27-C 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 Insignia NS-UZ70WH27-C cheap to run?
Yes. Its $55/yr running cost puts it at rank #126 of 622, below what most freezer models we track cost to run.
How much does the Insignia NS-UZ70WH27-C cost per month?
About $4.58 a month, which is the $55 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: 296 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $55 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Insignia NS-UZ70WH27-C for its size?
26th percentile once size is factored in, a fairly typical result for the class.
