Model
Maytag MRFF5336TZ
Rank #962 means 961 of the 1,000 refrigerator models we track cost less to run each year; the 79th efficiency percentile means it uses less energy for its size than 79% of those models.
What does the Maytag MRFF5336TZ cost to run per year?
Almost nothing we track in this class costs more to run than the Maytag MRFF5336TZ: about $133 a year, rank #962 of 1,000. It uses 14% less energy than the U.S. federal standard model in its class, which would cost about $151/yr to run, a saving of roughly $18 a year. Normalized for capacity, it beats 79% of refrigerator models we track, a better-than-average efficiency result. At 30 cu ft, it is a large 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.
Immediately around it on the leaderboard, the Frigidaire LGHB2869T* at $133/yr runs a little cheaper and the Whirlpool WRFF3536SW at $133/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 Maytag MRFF5336TZ's $133/yr adds up to roughly $1596 in electricity alone, before purchase price or repairs.
Also sold as: Whirlpool WRFF3536SW.
By the numbers
The Maytag MRFF5336TZ 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 $133/yr, here is what the Maytag MRFF5336TZ adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Maytag MRFF5336TZ costs about $1330. That is roughly $180 less than a standard model in its class, which would run closer to $1510 over the same ten years.
How the Maytag MRFF5336TZ compares
The refrigerator class we track runs from $8 to $149 a year. At $133/yr, it runs about $69 a year above the class median of $64, and it is about $125 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $151/yr, the Maytag MRFF5336TZ uses 14% less energy.
What drives its running cost
At 30 cu ft, the Maytag MRFF5336TZ is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, and larger refrigerator models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light.
- 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 Maytag MRFF5336TZ cheap to run?
Not especially. At $133 a year it ranks #962 of 1,000 refrigerator models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Maytag MRFF5336TZ cost per month?
Roughly $11.06/mo, spreading the $133/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 715 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $133 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Maytag MRFF5336TZ for its size?
79th 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.
