Model
Avanti AVFF21DLJM#**
Rank #619 means 618 of the 1,000 refrigerator models we track cost less to run each year; the 95th efficiency percentile means it uses less energy for its size than 95% of those models.
What does the Avanti AVFF21DLJM#** cost to run per year?
Among the 1,000 refrigerator models we track, the Avanti AVFF21DLJM#**'s $73/yr running cost ranks it #619, in the above-average-cost group. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $82/yr to run, a saving of roughly $9 a year. Few refrigerator models we track are more efficient for their size than this one; its size-adjusted efficiency percentile of 95 is near the top of the class. This class has no published efficiency-factor figure beyond annual kWh itself, so at 21 cu ft (the class spans 1.2 to 31.7), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Summit FF1141W at $73/yr runs a little cheaper and the Kitchenaid KBBX102MPA 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 Avanti AVFF21DLJM#**'s $73/yr adds up to roughly $876 in electricity alone, before purchase price or repairs.
By the numbers
The Avanti AVFF21DLJM#** 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 Avanti AVFF21DLJM#** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Avanti AVFF21DLJM#** costs about $730. That is roughly $90 less than a standard model in its class, which would run closer to $820 over the same ten years.
How the Avanti AVFF21DLJM#** 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 $82/yr, the Avanti AVFF21DLJM#** uses 11% less energy.
What drives its running cost
At 21 cu ft, the Avanti AVFF21DLJM#** is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, among refrigerator models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal.
- Interior volume. More cubic feet of cold air to maintain generally means a bigger compressor and a higher running-cost figure, even among efficient models.
- Counter depth vs standard depth. Standard-depth models generally offer more interior volume per unit of width than counter-depth models, a tradeoff between built-in looks and cubic feet.
- Compressor technology. How a compressor cycles, full on/off versus a variable-speed inverter design, is one of the biggest hidden differences behind two fridges with similar cubic feet but different running costs.
- Placement and ventilation. Ventilation clearance around the back and top matters more than most owners expect; a fridge starved of airflow runs its compressor longer to hold the same temperature.
Common questions
Is the Avanti AVFF21DLJM#** cheap to run?
Its $73/yr running cost, rank #619 of 1,000, is above what most refrigerator models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Avanti AVFF21DLJM#** cost per month?
About $6.08 a month, which is the $73 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: 393 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $73 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Avanti AVFF21DLJM#** for its size?
95th 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.
