Model
Conserv MDRF376-1150
Rank #628 means 627 of the 1,000 refrigerator models we track cost less to run each year; the 41st efficiency percentile means it uses less energy for its size than 41% of those models.
What does the Conserv MDRF376-1150 cost to run per year?
The Conserv MDRF376-1150 is a relatively costly runner for its class: about $74 a year, rank #628 of 1,000. It uses 14% more energy than the U.S. federal standard model in its class, which would cost about $65/yr to run, about $9 a year more. Its 41th size-adjusted efficiency percentile is unremarkable, close to what a typical model in the class scores. At 11.5 cu ft, it is a mid-size 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 Sankey RF 2363 SS at $73/yr runs a little cheaper and the Marathon MFF115***** at $74/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 Conserv MDRF376-1150's $74/yr adds up to roughly $888 in electricity alone, before purchase price or repairs.
By the numbers
The Conserv MDRF376-1150 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 $74/yr, here is what the Conserv MDRF376-1150 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Conserv MDRF376-1150 costs about $740. That is roughly $90 more than a standard model in its class, which would run closer to $650 over the same ten years.
How the Conserv MDRF376-1150 compares
The refrigerator class we track runs from $8 to $149 a year. At $74/yr, it runs about $10 a year above the class median of $64, and it is about $66 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $65/yr, the Conserv MDRF376-1150 uses 14% more energy.
What drives its running cost
At 11.5 cu ft, the Conserv MDRF376-1150 is a mid-size refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- 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 Conserv MDRF376-1150 cheap to run?
Not especially. At $74 a year it ranks #628 of 1,000 refrigerator models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Conserv MDRF376-1150 cost per month?
Roughly $6.14/mo, spreading the $74/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 397 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $74 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Conserv MDRF376-1150 for its size?
41st percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
