Model
Insignia NS-RTM10WH2-C
Rank #348 means 347 of the 1,000 refrigerator models we track cost less to run each year; the 56th efficiency percentile means it uses less energy for its size than 56% of those models.
What does the Insignia NS-RTM10WH2-C cost to run per year?
At $53 a year to run, the Insignia NS-RTM10WH2-C runs cheaper than most models in its class, ranking #348 of 1,000 refrigerator models we track. It uses 15% less energy than the U.S. federal standard model in its class, which would cost about $62/yr to run, a saving of roughly $9 a year. Once capacity is factored in, its efficiency percentile of 56 is fairly typical for the class, neither a standout nor a laggard. At 10.1 cu ft, it is a mid-size refrigerator for the class, which runs 1.2 to 31.7 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 Galanz GLR65MS1E02 at $52/yr runs a little cheaper and the Lg LB12S2000* at $53/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-RTM10WH2-C's $53/yr adds up to roughly $636 in electricity alone, before purchase price or repairs.
By the numbers
The Insignia NS-RTM10WH2-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 $53/yr, here is what the Insignia NS-RTM10WH2-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-RTM10WH2-C costs about $530. That is roughly $90 less than a standard model in its class, which would run closer to $620 over the same ten years.
How the Insignia NS-RTM10WH2-C compares
The refrigerator class we track runs from $8 to $149 a year. At $53/yr, it runs about $11 a year cheaper than the class median of $64, and it is about $45 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $62/yr, the Insignia NS-RTM10WH2-C uses 15% less energy.
What drives its running cost
At 10.1 cu ft, the Insignia NS-RTM10WH2-C is a mid-size refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- 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.
- 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.
- 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-RTM10WH2-C cheap to run?
Yes, relatively. At $53 a year it ranks #348 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Insignia NS-RTM10WH2-C cost per month?
Roughly $4.38/mo, spreading the $53/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 283 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $53 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Insignia NS-RTM10WH2-C for its size?
56th percentile once size is factored in, a fairly typical result for the class.
