Model
Samsung QN75QN90DAF
Rank #149 means 148 of the 172 television models we track cost less to run each year; the 11th efficiency percentile means it uses less energy for its size than 11% of those models.
What does the Samsung QN75QN90DAF cost to run per year?
Among the 172 television models we track, the Samsung QN75QN90DAF's $57/yr running cost ranks it #149, in the pricier fifth of the class. Capacity-normalized, it ranks ahead of just 11% of television models we track, a clearly below-average result. Its on-mode draw of 141.39 W is the number ENERGY STAR measures directly and the one this running-cost figure is built from.
Immediately around it on the leaderboard, the Xitrix XPN-DSA8650 at $57/yr runs a little cheaper and the Samsung QN83S85FAE at $58/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 QN75QN90DAF's $57/yr adds up to roughly $399 in electricity alone, before purchase price or repairs.
By the numbers
The Samsung QN75QN90DAF 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 $57/yr, here is what the Samsung QN75QN90DAF 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 QN75QN90DAF costs about $570. That is roughly $220 more than the class median, which would run closer to $350 over the same ten years.
How the Samsung QN75QN90DAF compares
The television class we track runs from $3 to $117 a year. At $57/yr, it runs about $22 a year above the class median of $35, and it is about $54 a year more than the cheapest television to run at $3.
What drives its running cost
At 74.6 in, the Samsung QN75QN90DAF 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. 141.39 W is the on-mode draw behind this figure (the class spans 9.3 to 343.5 W); two otherwise similar TVs can differ here mostly on picture-mode defaults rather than panel technology.
- On-mode brightness. On-mode watts, the figure ENERGY STAR measures at the factory picture setting, can differ a lot from what a TV actually draws once you change the picture mode.
- Screen size. Screen size is the single strongest predictor of a TV's on-mode wattage, ahead of panel technology or brand.
- Hours of use. Running cost compounds with hours of use, so this figure is really a per-hour rate multiplied by a standard viewing assumption, not a fixed annual bill.
Common questions
Is the Samsung QN75QN90DAF cheap to run?
Its $57/yr running cost, rank #149 of 172, is above what most television models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Samsung QN75QN90DAF cost per month?
About $4.76 a month, which is the $57 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 308 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $57 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Samsung QN75QN90DAF for its size?
11th 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.
