Model
Fisher & Paykel RS2435V2*
Rank #1 means 0 of the 1,000 refrigerator models we track cost less to run each year; the 100th efficiency percentile means it uses less energy for its size than 100% of those models.
What does the Fisher & Paykel RS2435V2* cost to run per year?
Few refrigerator models we track undercut the Fisher & Paykel RS2435V2* on cost; at about $8 a year it holds rank #1 of 1,000. It uses 78% less energy than the U.S. federal standard model in its class, which would cost about $35/yr to run, a saving of roughly $27 a year. Normalized for capacity, it ranks ahead of 100% of refrigerator models we track on efficiency, an exceptional showing for the class. At 4.3 cu ft, it is a small 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.
On the leaderboard, the Kalamazoo Outdoor Gourmet UKS15W*1-5-**** at $18/yr runs a little more, the closest neighbor to its exact spot in the ranking. A refrigerator typically stays in service for somewhere around 12 years; over that span, the Fisher & Paykel RS2435V2*'s $8/yr adds up to roughly $96 in electricity alone, before purchase price or repairs. At rank #1 of 1,000, it is one of the single cheapest refrigerator models we track to run, in the top one percent on cost.
By the numbers
The Fisher & Paykel RS2435V2* 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 $8/yr, here is what the Fisher & Paykel RS2435V2* adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Fisher & Paykel RS2435V2* costs about $80. That is roughly $270 less than a standard model in its class, which would run closer to $350 over the same ten years.
How the Fisher & Paykel RS2435V2* compares
The refrigerator class we track runs from $8 to $149 a year. At $8/yr, it runs about $56 a year cheaper than the class median of $64, and it is the cheapest refrigerator to run in the class among the models we track. Against the US federal standard model for its class at about $35/yr, the Fisher & Paykel RS2435V2* uses 78% less energy.
What drives its running cost
At 4.3 cu ft, the Fisher & Paykel RS2435V2* is a small refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture.
- 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 Fisher & Paykel RS2435V2* cheap to run?
Yes, relatively. At $8 a year it ranks #1 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Fisher & Paykel RS2435V2* cost per month?
Roughly $0.65/mo, spreading the $8/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 42 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $8 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Fisher & Paykel RS2435V2* for its size?
100th 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.
Cheaper to run in the same class
This is already the cheapest model to run in its class among the ones we track.
