Model
Fisher & Paykel RB36S
Rank #139 means 138 of the 622 freezer models we track cost less to run each year; the 7th efficiency percentile means it uses less energy for its size than 7% of those models.
What does the Fisher & Paykel RB36S cost to run per year?
Among the 622 freezer models we track, the Fisher & Paykel RB36S sits in the below-average-cost group, rank #139, at roughly $56 a year. It uses 28% less energy than the U.S. federal standard model in its class, which would cost about $78/yr to run, a saving of roughly $22 a year. Efficiency-wise, once size is accounted for, it lags most of the class, ahead of only 7% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 3.7 cu ft (the class spans 1.1 to 23), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Comfee CERU07B0*** at $56/yr runs a little cheaper and the Frigidaire FFUE0736AW at $56/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A freezer typically stays in service for somewhere around 14 years; over that span, the Fisher & Paykel RB36S's $56/yr adds up to roughly $784 in electricity alone, before purchase price or repairs.
By the numbers
The Fisher & Paykel RB36S 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 $56/yr, here is what the Fisher & Paykel RB36S 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 RB36S costs about $560. That is roughly $220 less than a standard model in its class, which would run closer to $780 over the same ten years.
How the Fisher & Paykel RB36S compares
The freezer class we track runs from $25 to $120 a year. At $56/yr, it runs about $19 a year cheaper than the class median of $75, and it is about $31 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $78/yr, the Fisher & Paykel RB36S uses 28% less energy.
What drives its running cost
At 3.7 cu ft, the Fisher & Paykel RB36S is a small freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- Interior volume. As with refrigerators, more cubic feet of frozen storage generally means a bigger compressor and a higher annual energy figure.
- Insulation and defrost type. Better-insulated cabinets lose less cold to the surrounding room, and frost-free (automatic-defrost) freezers run a periodic heating element that a manual-defrost model does not.
- Chest vs upright design. Door orientation affects how much cold air escapes per opening: top-opening chest designs generally hold cold better than front-opening upright ones.
Common questions
Is the Fisher & Paykel RB36S cheap to run?
Yes. Its $56/yr running cost puts it at rank #139 of 622, below what most freezer models we track cost to run.
How much does the Fisher & Paykel RB36S cost per month?
About $4.64 a month, which is the $56 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: 300 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $56 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Fisher & Paykel RB36S for its size?
7th percentile once size is factored in, a fairly typical result for the class.
