Model
Monogram ZIF241NPN****
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 ZIF241NPN**** cost to run per year?
The Monogram ZIF241NPN**** holds rank #563 of 622 on running cost, at about $95 a year, a genuinely pricey result for the class. 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. Size-adjusted, this model trails most of its class on efficiency, ahead of just 29% of freezer models we track. 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 Monogram ZIF241NBR**** at $95/yr runs a little cheaper and the Avanti AV230VFLJM#** at $97/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 ZIF241NPN****'s $95/yr adds up to roughly $1330 in electricity alone, before purchase price or repairs.

By the numbers
The Monogram ZIF241NPN**** 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 ZIF241NPN**** 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 ZIF241NPN**** 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 ZIF241NPN**** 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 ZIF241NPN**** uses 10% less energy.
What drives its running cost
At 12.5 cu ft, the Monogram ZIF241NPN**** is a mid-size freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- 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 ZIF241NPN**** 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 ZIF241NPN**** 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 ZIF241NPN**** 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.
