Model
Marvel MPWC424-SG31A
Rank #241 means 240 of the 1,000 refrigerator models we track cost less to run each year; the 32nd efficiency percentile means it uses less energy for its size than 32% of those models.
What does the Marvel MPWC424-SG31A cost to run per year?
At roughly $46 a year to run, ranking #241 of 1,000, the Marvel MPWC424-SG31A costs less than the typical refrigerator model we track. It uses 19% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $11 a year. Its size-adjusted efficiency percentile of 32 suggests its capacity is doing more work than its efficiency to keep the headline cost down. It is a counter-depth model, built shallower to sit flush with kitchen cabinets, a design choice that typically trades away some interior volume (and so some running-cost headroom) for the built-in look.
Immediately around it on the leaderboard, the Marvel MPBV424-IG31A at $46/yr runs a little cheaper and the Perlick URS15T*1-5-**** at $46/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 Marvel MPWC424-SG31A's $46/yr adds up to roughly $552 in electricity alone, before purchase price or repairs.
By the numbers
The Marvel MPWC424-SG31A 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 $46/yr, here is what the Marvel MPWC424-SG31A adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Marvel MPWC424-SG31A costs about $460. That is roughly $110 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Marvel MPWC424-SG31A compares
The refrigerator class we track runs from $8 to $149 a year. At $46/yr, it runs about $18 a year cheaper than the class median of $64, and it is about $38 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $57/yr, the Marvel MPWC424-SG31A uses 19% less energy.
What drives its running cost
At 5.2 cu ft, the Marvel MPWC424-SG31A is a small refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- 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.
- 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.
- 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 Marvel MPWC424-SG31A cheap to run?
Yes. Its $46/yr running cost puts it at rank #241 of 1,000, below what most refrigerator models we track cost to run.
How much does the Marvel MPWC424-SG31A cost per month?
About $3.85 a month, which is the $46 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: 249 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $46 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Marvel MPWC424-SG31A for its size?
32nd percentile once size is factored in, a fairly typical result for the class.
