Model
Marathon MFF180WFD-1
Rank #662 means 661 of the 1,000 refrigerator models we track cost less to run each year; the 77th efficiency percentile means it uses less energy for its size than 77% of those models.
What does the Marathon MFF180WFD-1 cost to run per year?
The Marathon MFF180WFD-1 is a relatively costly runner for its class: about $81 a year, rank #662 of 1,000. It uses 15% less energy than the U.S. federal standard model in its class, which would cost about $94/yr to run, a saving of roughly $13 a year. Once capacity is factored in, its 77th efficiency percentile puts it ahead of most peers in its class. At 17.7 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 Marathon MFF180SSFD at $81/yr runs a little cheaper and the Stovv F18HF01SW at $81/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 Marathon MFF180WFD-1's $81/yr adds up to roughly $972 in electricity alone, before purchase price or repairs.

By the numbers
The Marathon MFF180WFD-1 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 $81/yr, here is what the Marathon MFF180WFD-1 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Marathon MFF180WFD-1 costs about $810. That is roughly $130 less than a standard model in its class, which would run closer to $940 over the same ten years.
How the Marathon MFF180WFD-1 compares
The refrigerator class we track runs from $8 to $149 a year. At $81/yr, it runs about $17 a year above the class median of $64, and it is about $73 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $94/yr, the Marathon MFF180WFD-1 uses 15% less energy.
What drives its running cost
At 17.7 cu ft, the Marathon MFF180WFD-1 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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- 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 Marathon MFF180WFD-1 cheap to run?
Not especially. At $81 a year it ranks #662 of 1,000 refrigerator models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Marathon MFF180WFD-1 cost per month?
Roughly $6.73/mo, spreading the $81/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 435 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $81 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Marathon MFF180WFD-1 for its size?
77th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
