Model
Samsung QN98QN90FAF
Rank #162 means 161 of the 172 television models we track cost less to run each year; the 30th efficiency percentile means it uses less energy for its size than 30% of those models.
What does the Samsung QN98QN90FAF cost to run per year?
Not many television models we track cost more to run than the Samsung QN98QN90FAF: about $66 a year, rank #162 of 172. Adjusted for size, it is only more efficient than 30% of television models we track, so part of its running cost comes from its capacity rather than efficiency alone. At 193.08 W in on-mode, its power draw is a direct input into that running-cost figure.
Immediately around it on the leaderboard, the Lg OLED77G5*** at $65/yr runs a little cheaper and the Samsung QN77S95DAF at $67/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 QN98QN90FAF's $66/yr adds up to roughly $462 in electricity alone, before purchase price or repairs.
By the numbers
The Samsung QN98QN90FAF 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 $66/yr, here is what the Samsung QN98QN90FAF 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 QN98QN90FAF costs about $660. That is roughly $310 more than the class median, which would run closer to $350 over the same ten years.
How the Samsung QN98QN90FAF compares
The television class we track runs from $3 to $117 a year. At $66/yr, it runs about $31 a year above the class median of $35, and it is about $63 a year more than the cheapest television to run at $3.
What drives its running cost
At 97.5 in, the Samsung QN98QN90FAF is a large television for its class, which spans 13.23 to 114.4 in with a median of 55 in, and larger television models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. Its on-mode power draw of 193.08 W (the class spans 9.3 to 343.5 W) is the direct input into the running-cost figure, and the picture-brightness setting you choose is the single biggest lever you control over it day to day.
- 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.
- 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.
- 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 QN98QN90FAF cheap to run?
Not especially. At $66 a year it ranks #162 of 172 television 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 Samsung QN98QN90FAF cost per month?
Roughly $5.53/mo, spreading the $66/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 357 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $66 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Samsung QN98QN90FAF for its size?
30th 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.
