Model
Monogram ZIF241NBR****
Rank #563 means 562 of the 622 freezer models we track cost less to run each year; the 29th efficiency percentile means it uses less energy for its size than 29% of those models.
What does the Monogram ZIF241NBR**** cost to run per year?
The Monogram ZIF241NBR**** costs about $95 a year to run, well up the cost table for its class at rank #563 of 622. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $104/yr to run, a saving of roughly $9 a year. Its size-adjusted efficiency percentile of 29 suggests its capacity is doing more work than its efficiency to keep the headline cost down. This class has no published efficiency-factor figure beyond annual kWh itself, so at 12.5 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 Sub-Zero DEC2450FI/* at $95/yr runs a little cheaper and the Monogram ZIF241NPN**** at $95/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 Monogram ZIF241NBR****'s $95/yr adds up to roughly $1330 in electricity alone, before purchase price or repairs.

By the numbers
The Monogram ZIF241NBR**** 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 $95/yr, here is what the Monogram ZIF241NBR**** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Monogram ZIF241NBR**** costs about $950. That is roughly $90 less than a standard model in its class, which would run closer to $1040 over the same ten years.
How the Monogram ZIF241NBR**** compares
The freezer class we track runs from $25 to $120 a year. At $95/yr, it runs about $20 a year above the class median of $75, and it is about $70 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $104/yr, the Monogram ZIF241NBR**** uses 10% less energy.
What drives its running cost
At 12.5 cu ft, the Monogram ZIF241NBR**** is a mid-size freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- 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 Monogram ZIF241NBR**** cheap to run?
Its $95/yr running cost, rank #563 of 622, is above what most freezer models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Monogram ZIF241NBR**** cost per month?
About $7.93 a month, which is the $95 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: 513 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $95 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Monogram ZIF241NBR**** for its size?
29th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
