Model
Elisii DERTM181WW4
Rank #559 means 558 of the 1,000 refrigerator models we track cost less to run each year; the 90th efficiency percentile means it uses less energy for its size than 90% of those models.
What does the Elisii DERTM181WW4 cost to run per year?
Ranking #559 of 1,000, the Elisii DERTM181WW4 runs at roughly $67 a year, neither the cheapest nor the priciest in its class. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $75/yr to run, a saving of roughly $8 a year. Adjusted for its size, it is more efficient than 90% of refrigerator models we track, a strong result once size is taken into account. At 18 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 Elisii DERTM180SW2 at $67/yr runs a little cheaper and the Hisense HRT180N6A*E at $67/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 Elisii DERTM181WW4's $67/yr adds up to roughly $804 in electricity alone, before purchase price or repairs.
Also sold as: Criterion 18TMF-B.
By the numbers
The Elisii DERTM181WW4 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 $67/yr, here is what the Elisii DERTM181WW4 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Elisii DERTM181WW4 costs about $670. That is roughly $80 less than a standard model in its class, which would run closer to $750 over the same ten years.
How the Elisii DERTM181WW4 compares
The refrigerator class we track runs from $8 to $149 a year. At $67/yr, it runs about $3 a year above the class median of $64, and it is about $59 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $75/yr, the Elisii DERTM181WW4 uses 10% less energy.
What drives its running cost
At 18 cu ft, the Elisii DERTM181WW4 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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- 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 Elisii DERTM181WW4 cheap to run?
It is about average. At $67 a year it ranks #559 of 1,000 refrigerator models we track, close to the middle of its class on running cost.
How much does the Elisii DERTM181WW4 cost per month?
Roughly $5.61/mo, spreading the $67/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 363 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $67 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Elisii DERTM181WW4 for its size?
90th percentile once size is factored in, a fairly typical result for the class.
