Model
Insignia NS-CF30TMSS6-C
Rank #322 means 321 of the 1,000 refrigerator models we track cost less to run each year; the 9th efficiency percentile means it uses less energy for its size than 9% of those models.
What does the Insignia NS-CF30TMSS6-C cost to run per year?
The Insignia NS-CF30TMSS6-C is a relatively cheap runner for its class: about $51 a year, rank #322 of 1,000. It uses 7% more energy than the U.S. federal standard model in its class, which would cost about $47/yr to run, about $4 a year more. Its 9th size-adjusted efficiency percentile is well below the class median, worth weighing against the raw cost figure above. It is a counter-depth model, built shallower to sit flush with kitchen cabinets, a design choice that typically trades away some interior volume (and so some running-cost headroom) for the built-in look.
Immediately around it on the leaderboard, the Perlick HA24B*4C-**-***** at $50/yr runs a little cheaper and the Cafe CCR06BM*P*** at $51/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A refrigerator typically stays in service for somewhere around 12 years; over that span, the Insignia NS-CF30TMSS6-C's $51/yr adds up to roughly $612 in electricity alone, before purchase price or repairs.
By the numbers
The Insignia NS-CF30TMSS6-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 $51/yr, here is what the Insignia NS-CF30TMSS6-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-CF30TMSS6-C costs about $510. That is roughly $40 more than a standard model in its class, which would run closer to $470 over the same ten years.
How the Insignia NS-CF30TMSS6-C compares
The refrigerator class we track runs from $8 to $149 a year. At $51/yr, it runs about $13 a year cheaper than the class median of $64, and it is about $43 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $47/yr, the Insignia NS-CF30TMSS6-C uses 7% more energy.
What drives its running cost
At 2.9 cu ft, the Insignia NS-CF30TMSS6-C is a small refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 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.
- Counter depth vs standard depth. Counter-depth models sit flush with cabinets but usually hold less interior volume than a standard-depth model of the same width, which can nudge the per-cubic-foot running cost either way.
- Interior volume. Cubic feet of interior volume is the first thing that scales a fridge's running cost up or down, before compressor quality even enters the picture.
- Compressor technology. Newer variable-speed (inverter) compressors modulate output instead of cycling fully on and off, which tends to use less energy for the same cooling job than an older fixed-speed compressor.
- Placement and ventilation. A fridge pushed tight against a wall or cabinet, or standing next to an oven or in direct sun, works harder to shed the heat its compressor produces, which can push real-world cost above the published figure.
Common questions
Is the Insignia NS-CF30TMSS6-C cheap to run?
Yes, relatively. At $51 a year it ranks #322 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Insignia NS-CF30TMSS6-C cost per month?
Roughly $4.22/mo, spreading the $51/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 273 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $51 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Insignia NS-CF30TMSS6-C for its size?
9th percentile once size is factored in, a fairly typical result for the class.
