Model
Xo XOU24WGSL
Rank #33 means 32 of the 1,000 refrigerator models we track cost less to run each year; the 57th efficiency percentile means it uses less energy for its size than 57% of those models.
What does the Xo XOU24WGSL cost to run per year?
Out of the 1,000 refrigerator models we track, the Xo XOU24WGSL lands at rank #33 on cost, roughly $29 a year, a standout figure at the cheap end of the class. It uses 21% less energy than the U.S. federal standard model in its class, which would cost about $37/yr to run, a saving of roughly $8 a year. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 57% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 5.7 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 Hisense HWS054N6SS at $29/yr runs a little cheaper and the Zephyr PRPW24C01BG at $30/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 Xo XOU24WGSL's $29/yr adds up to roughly $348 in electricity alone, before purchase price or repairs.
By the numbers
The Xo XOU24WGSL 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 $29/yr, here is what the Xo XOU24WGSL adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Xo XOU24WGSL costs about $290. That is roughly $80 less than a standard model in its class, which would run closer to $370 over the same ten years.
How the Xo XOU24WGSL compares
The refrigerator class we track runs from $8 to $149 a year. At $29/yr, it runs about $35 a year cheaper than the class median of $64, and it is about $21 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $37/yr, the Xo XOU24WGSL uses 21% less energy.
What drives its running cost
At 5.7 cu ft, the Xo XOU24WGSL 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, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone.
- 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 Xo XOU24WGSL cheap to run?
Yes. Its $29/yr running cost puts it at rank #33 of 1,000, below what most refrigerator models we track cost to run.
How much does the Xo XOU24WGSL cost per month?
About $2.44 a month, which is the $29 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: 158 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $29 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Xo XOU24WGSL for its size?
57th 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.
