Model
Danby DFF070B2BSLDB-6
Rank #616 means 615 of the 1,000 refrigerator models we track cost less to run each year; the 26th efficiency percentile means it uses less energy for its size than 26% of those models.
What does the Danby DFF070B2BSLDB-6 cost to run per year?
Do the math and the Danby DFF070B2BSLDB-6's $73/yr puts it at rank #616 of 1,000, on the pricier side of the class. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $81/yr to run, a saving of roughly $8 a year. Adjusted for size, it is only more efficient than 26% of refrigerator models we track, so part of its running cost comes from its capacity rather than efficiency alone. At 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 Unique UGP-330L W AC at $72/yr runs a little cheaper and the Hisense RB11N6C*E at $73/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 DFF070B2BSLDB-6's $73/yr adds up to roughly $876 in electricity alone, before purchase price or repairs.
By the numbers
The Danby DFF070B2BSLDB-6 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 $73/yr, here is what the Danby DFF070B2BSLDB-6 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 DFF070B2BSLDB-6 costs about $730. That is roughly $80 less than a standard model in its class, which would run closer to $810 over the same ten years.
How the Danby DFF070B2BSLDB-6 compares
The refrigerator class we track runs from $8 to $149 a year. At $73/yr, it runs about $9 a year above the class median of $64, and it is about $65 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $81/yr, the Danby DFF070B2BSLDB-6 uses 11% less energy.
What drives its running cost
At 7 cu ft, the Danby DFF070B2BSLDB-6 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 DFF070B2BSLDB-6 cheap to run?
Not especially. At $73 a year it ranks #616 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 Danby DFF070B2BSLDB-6 cost per month?
Roughly $6.05/mo, spreading the $73/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 391 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $73 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Danby DFF070B2BSLDB-6 for its size?
26th 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.
