Model
Midea MRF29D3AWW
Rank #994 means 993 of the 1,000 refrigerator models we track cost less to run each year; the 62nd efficiency percentile means it uses less energy for its size than 62% of those models.
What does the Midea MRF29D3AWW cost to run per year?
The Midea MRF29D3AWW costs about $145 a year to run, near the very top of the cost table for its class at rank #994 of 1,000. It uses 5% less energy than the U.S. federal standard model in its class, which would cost about $152/yr to run, a saving of roughly $7 a year. Its size-adjusted efficiency percentile of 62 is comfortably above the class median. This class has no published efficiency-factor figure beyond annual kWh itself, so at 29.3 cu ft (the class spans 1.2 to 31.7), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Midea MDRF1100FGF04PRG at $145/yr runs a little cheaper and the Lg LF29H8330* at $146/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 MRF29D3AWW's $145/yr adds up to roughly $1740 in electricity alone, before purchase price or repairs. At rank #994 of 1,000, it sits at the very top of the cost range for its class, among the single priciest models we track to run.

By the numbers
The Midea MRF29D3AWW 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 $145/yr, here is what the Midea MRF29D3AWW 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 MRF29D3AWW costs about $1450. That is roughly $70 less than a standard model in its class, which would run closer to $1520 over the same ten years.
How the Midea MRF29D3AWW compares
The refrigerator class we track runs from $8 to $149 a year. At $145/yr, it runs about $81 a year above the class median of $64, and it is about $137 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $152/yr, the Midea MRF29D3AWW uses 5% less energy.
What drives its running cost
At 29.3 cu ft, the Midea MRF29D3AWW 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. More cubic feet of cold air to maintain generally means a bigger compressor and a higher running-cost figure, even among efficient models.
- Counter depth vs standard depth. Standard-depth models generally offer more interior volume per unit of width than counter-depth models, a tradeoff between built-in looks and cubic feet.
- Compressor technology. How a compressor cycles, full on/off versus a variable-speed inverter design, is one of the biggest hidden differences behind two fridges with similar cubic feet but different running costs.
- Placement and ventilation. Ventilation clearance around the back and top matters more than most owners expect; a fridge starved of airflow runs its compressor longer to hold the same temperature.
Common questions
Is the Midea MRF29D3AWW cheap to run?
Its $145/yr running cost, rank #994 of 1,000, is above what most refrigerator models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Midea MRF29D3AWW cost per month?
About $12.09 a month, which is the $145 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: 782 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $145 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MRF29D3AWW for its size?
62nd 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.
