Model
Seasons MSTF18WHR5
Rank #578 means 577 of the 1,000 refrigerator models we track cost less to run each year; the 88th efficiency percentile means it uses less energy for its size than 88% of those models.
What does the Seasons MSTF18WHR5 cost to run per year?
Do the math and the Seasons MSTF18WHR5's $68/yr puts it at rank #578 of 1,000, right around the class average. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $76/yr to run, a saving of roughly $8 a year. Adjusted for its size, it is more efficient than 88% of refrigerator models we track, a strong result once size is taken into account. At 18.1 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 Midea UR-BCD512WX-SQ-IK at $68/yr runs a little cheaper and the Amana ART348FFF*** at $69/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 Seasons MSTF18WHR5's $68/yr adds up to roughly $816 in electricity alone, before purchase price or repairs.

By the numbers
The Seasons MSTF18WHR5 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 $68/yr, here is what the Seasons MSTF18WHR5 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Seasons MSTF18WHR5 costs about $680. That is roughly $80 less than a standard model in its class, which would run closer to $760 over the same ten years.
How the Seasons MSTF18WHR5 compares
The refrigerator class we track runs from $8 to $149 a year. At $68/yr, it runs about $4 a year above the class median of $64, and it is about $60 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $76/yr, the Seasons MSTF18WHR5 uses 10% less energy.
What drives its running cost
At 18.1 cu ft, the Seasons MSTF18WHR5 is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up.
- 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 Seasons MSTF18WHR5 cheap to run?
It is about average. At $68 a year it ranks #578 of 1,000 refrigerator models we track, close to the middle of its class on running cost.
How much does the Seasons MSTF18WHR5 cost per month?
Roughly $5.71/mo, spreading the $68/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 369 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $68 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Seasons MSTF18WHR5 for its size?
88th percentile once size is factored in, a fairly typical result for the class.
