Samsung QN48S90HAE
Rank #52 means 51 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 QN48S90HAE cost to run per year?
The Samsung QN48S90HAE is a relatively cheap runner for its class: about $27 a year, rank #52 of 172. Once capacity is factored in, its 60th efficiency percentile puts it ahead of most peers in its class. At 47.5 in, it is a small 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 Samsung QN43QN90DAF at $27/yr runs a little cheaper and the Samsung QN50QN90FAF at $27/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 QN48S90HAE's $27/yr adds up to roughly $189 in electricity alone, before purchase price or repairs.
By the numbers
The Samsung QN48S90HAE 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 $27/yr, here is what the Samsung QN48S90HAE 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 QN48S90HAE costs about $270. That is roughly $80 less than the class median, which would run closer to $350 over the same ten years.
How the Samsung QN48S90HAE compares
The television class we track runs from $3 to $117 a year. At $27/yr, it runs about $8 a year cheaper than the class median of $35, and it is about $24 a year more than the cheapest television to run at $3.
What drives its running cost
At 47.5 in, the Samsung QN48S90HAE is a small television for its class, which spans 13.23 to 114.4 in with a median of 55 in, 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.
- 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 QN48S90HAE cheap to run?
Yes, relatively. At $27 a year it ranks #52 of 172 television models we track, in the cheaper part of its class to run.
How much does the Samsung QN48S90HAE cost per month?
Roughly $2.23/mo, spreading the $27/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 144 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $27 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Samsung QN48S90HAE for its size?
60th percentile once size is factored in, a fairly typical result for the class.
