Model
Danby DFF101B2WDB
Rank #368 means 367 of the 1,000 refrigerator models we track cost less to run each year; the 51st efficiency percentile means it uses less energy for its size than 51% of those models.
What does the Danby DFF101B2WDB cost to run per year?
At $55 a year to run, the Danby DFF101B2WDB runs cheaper than most models in its class, ranking #368 of 1,000 refrigerator models we track. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $62/yr to run, a saving of roughly $7 a year. Its 51th size-adjusted efficiency percentile is unremarkable, close to what a typical model in the class scores. 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 Black Decker BR1000HS at $55/yr runs a little cheaper and the Frestec FR 1002 WHB at $55/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 Danby DFF101B2WDB's $55/yr adds up to roughly $660 in electricity alone, before purchase price or repairs.

By the numbers
The Danby DFF101B2WDB 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 $55/yr, here is what the Danby DFF101B2WDB adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Danby DFF101B2WDB costs about $550. That is roughly $70 less than a standard model in its class, which would run closer to $620 over the same ten years.
How the Danby DFF101B2WDB compares
The refrigerator class we track runs from $8 to $149 a year. At $55/yr, it runs about $9 a year cheaper than the class median of $64, and it is about $47 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 Danby DFF101B2WDB uses 11% less energy.
What drives its running cost
At 10.1 cu ft, the Danby DFF101B2WDB 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 Danby DFF101B2WDB cheap to run?
Yes, relatively. At $55 a year it ranks #368 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Danby DFF101B2WDB cost per month?
Roughly $4.59/mo, spreading the $55/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 297 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $55 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Danby DFF101B2WDB for its size?
51st percentile once size is factored in, a fairly typical result for the class.
