Model
Midea MRT18D3***
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 Midea MRT18D3*** cost to run per year?
Do the math and the Midea MRT18D3***'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. Normalized for capacity, it ranks ahead of 88% of refrigerator models we track on efficiency, a genuinely strong showing. 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 Koolmore KM-TMR-18-SS at $68/yr runs a little cheaper and the Midea UR-BCD512WX-SQ-IK at $68/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 Midea MRT18D3***'s $68/yr adds up to roughly $816 in electricity alone, before purchase price or repairs.

By the numbers
The Midea MRT18D3*** 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 Midea MRT18D3*** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Midea MRT18D3*** 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 Midea MRT18D3*** 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 Midea MRT18D3*** uses 10% less energy.
What drives its running cost
At 18.1 cu ft, the Midea MRT18D3*** 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 Midea MRT18D3*** 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 Midea MRT18D3*** 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 Midea MRT18D3*** for its size?
88th percentile once size is factored in, a fairly typical result for the class.
