Samsung QN55S85DAE
Rank #69 means 68 of the 172 television models we track cost less to run each year; the 60th efficiency percentile means it uses less energy for its size than 60% of those models.
What does the Samsung QN55S85DAE cost to run per year?
Ranking #69 of 172, the Samsung QN55S85DAE runs at roughly $31 a year, neither the cheapest nor the priciest in its class. Adjusted for size, it is more efficient than 60% of television models we track, a solidly above-average result. At 54.6 in, it is a mid-size television for the class, which runs 13.23 to 114.4 in; 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 Lg OLED48C5*** at $30/yr runs a little cheaper and the Samsung QN50QN90DAF at $31/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A television typically stays in service for somewhere around 7 years; over that span, the Samsung QN55S85DAE's $31/yr adds up to roughly $217 in electricity alone, before purchase price or repairs.
By the numbers
The Samsung QN55S85DAE 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 $31/yr, here is what the Samsung QN55S85DAE adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Samsung QN55S85DAE costs about $310. That is roughly $40 less than the class median, which would run closer to $350 over the same ten years.
How the Samsung QN55S85DAE compares
The television class we track runs from $3 to $117 a year. At $31/yr, it runs about $4 a year cheaper than the class median of $35, and it is about $28 a year more than the cheapest television to run at $3.
What drives its running cost
At 54.6 in, the Samsung QN55S85DAE is a mid-size television for its class, which spans 13.23 to 114.4 in with a median of 55 in, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- Screen size. A bigger panel needs more backlight or more emissive pixels to reach the same brightness, so energy use climbs with diagonal screen size across most panel technologies.
- On-mode brightness. The picture mode you leave a TV on, vivid or eco, moves its real-world wattage more than almost anything else you control directly.
- Hours of use. ENERGY STAR's on-mode wattage figure assumes a standard number of hours per day; a TV left on longer than that, or used as ambient background noise, accumulates more of that hourly cost.
Common questions
Is the Samsung QN55S85DAE cheap to run?
It is about average. At $31 a year it ranks #69 of 172 television models we track, close to the middle of its class on running cost.
How much does the Samsung QN55S85DAE cost per month?
Roughly $2.55/mo, spreading the $31/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 165 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $31 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Samsung QN55S85DAE for its size?
60th percentile once size is factored in, a fairly typical result for the class.
