Model
Fisher & Paykel RS18F
Rank #317 means 316 of the 622 freezer models we track cost less to run each year; the 15th efficiency percentile means it uses less energy for its size than 15% of those models.
What does the Fisher & Paykel RS18F cost to run per year?
The Fisher & Paykel RS18F costs about $77 a year to run, a fairly typical figure for the class; it ranks #317 of 622. It uses 15% less energy than the U.S. federal standard model in its class, which would cost about $89/yr to run, a saving of roughly $12 a year. Efficiency-wise, once size is accounted for, it lags most of the class, ahead of only 15% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 7.8 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 Liebherr MF1851 at $76/yr runs a little cheaper and the Frigidaire FFUE1626AV at $77/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 RS18F's $77/yr adds up to roughly $1078 in electricity alone, before purchase price or repairs.
By the numbers
The Fisher & Paykel RS18F 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 $77/yr, here is what the Fisher & Paykel RS18F 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 RS18F costs about $770. That is roughly $120 less than a standard model in its class, which would run closer to $890 over the same ten years.
How the Fisher & Paykel RS18F compares
The freezer class we track runs from $25 to $120 a year. At $77/yr, it runs about $2 a year above the class median of $75, and it is about $52 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $89/yr, the Fisher & Paykel RS18F uses 15% less energy.
What drives its running cost
At 7.8 cu ft, the Fisher & Paykel RS18F is a small freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, and smaller freezer models generally cost less to run for the same job, all else being equal.
- 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 RS18F cheap to run?
Roughly, yes. Its $77/yr figure is close to the class median, ranking #317 of 622, neither a bargain nor a splurge on running cost.
How much does the Fisher & Paykel RS18F cost per month?
About $6.42 a month, which is the $77 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: 415 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $77 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Fisher & Paykel RS18F for its size?
15th percentile once size is factored in, a fairly typical result for the class.
