Model
Samsung QN55S90HAE
Rank #93 means 92 of the 172 television 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 Samsung QN55S90HAE cost to run per year?
At $37 a year to run, the Samsung QN55S90HAE sits close to the middle of its class on cost, ranking #93 of 172 television models we track. Once capacity is factored in, its efficiency percentile of 32 is below the class median, worth weighing alongside the raw dollar figure. 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 55LX1TPU* at $36/yr runs a little cheaper and the Lg OLED55C6PU* at $37/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 QN55S90HAE's $37/yr adds up to roughly $259 in electricity alone, before purchase price or repairs.
By the numbers
The Samsung QN55S90HAE 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 $37/yr, here is what the Samsung QN55S90HAE 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 QN55S90HAE costs about $370. That is roughly $20 more than the class median, which would run closer to $350 over the same ten years.
How the Samsung QN55S90HAE compares
The television class we track runs from $3 to $117 a year. At $37/yr, it runs about $2 a year above the class median of $35, and it is about $34 a year more than the cheapest television to run at $3.
What drives its running cost
At 54.6 in, the Samsung QN55S90HAE 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 QN55S90HAE cheap to run?
It is about average. At $37 a year it ranks #93 of 172 television models we track, close to the middle of its class on running cost.
