Model
Magic Chef HMTR450SE
Rank #291 means 290 of the 1,000 refrigerator models we track cost less to run each year; the 26th efficiency percentile means it uses less energy for its size than 26% of those models.
What does the Magic Chef HMTR450SE cost to run per year?
Among the 1,000 refrigerator models we track, the Magic Chef HMTR450SE sits in the below-average-cost group, rank #291, at roughly $49 a year. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $55/yr to run, a saving of roughly $6 a year. Capacity-normalized, it ranks ahead of just 26% of refrigerator models we track, a soft spot worth weighing against the dollar figure. This class has no published efficiency-factor figure beyond annual kWh itself, so at 4.5 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 Danby DCR045B1****** at $49/yr runs a little cheaper and the Thor Kitchen RBC24SSD-BLK at $49/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 Magic Chef HMTR450SE's $49/yr adds up to roughly $588 in electricity alone, before purchase price or repairs.

By the numbers
The Magic Chef HMTR450SE 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 $49/yr, here is what the Magic Chef HMTR450SE adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Magic Chef HMTR450SE costs about $490. That is roughly $60 less than a standard model in its class, which would run closer to $550 over the same ten years.
How the Magic Chef HMTR450SE compares
The refrigerator class we track runs from $8 to $149 a year. At $49/yr, it runs about $15 a year cheaper than the class median of $64, and it is about $41 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $55/yr, the Magic Chef HMTR450SE uses 11% less energy.
What drives its running cost
At 4.5 cu ft, the Magic Chef HMTR450SE is a small refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, and smaller refrigerator models generally cost less to run for the same job, all else being equal.
- 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 Magic Chef HMTR450SE cheap to run?
Yes. Its $49/yr running cost puts it at rank #291 of 1,000, below what most refrigerator models we track cost to run.
How much does the Magic Chef HMTR450SE cost per month?
About $4.1 a month, which is the $49 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: 265 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $49 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Magic Chef HMTR450SE for its size?
26th percentile once size is factored in, a fairly typical result for the class.
