Samsung QN77S85HAE
Rank #133 means 132 of the 172 television models we track cost less to run each year; the 37th efficiency percentile means it uses less energy for its size than 37% of those models.
What does the Samsung QN77S85HAE cost to run per year?
Ranking #133 of 172, the Samsung QN77S85HAE sits in the pricier half of its class to run, at about $50 a year. Normalized for capacity, it beats only 37% of television models we track, a below-average efficiency result. At 76.6 in, it is a large 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 QN75QN90FAF at $50/yr runs a little cheaper and the Samsung QN77S85FAE at $50/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 QN77S85HAE's $50/yr adds up to roughly $350 in electricity alone, before purchase price or repairs.
By the numbers
The Samsung QN77S85HAE 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 $50/yr, here is what the Samsung QN77S85HAE 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 QN77S85HAE costs about $500. That is roughly $150 more than the class median, which would run closer to $350 over the same ten years.
How the Samsung QN77S85HAE compares
The television class we track runs from $3 to $117 a year. At $50/yr, it runs about $15 a year above the class median of $35, and it is about $47 a year more than the cheapest television to run at $3.
What drives its running cost
At 76.6 in, the Samsung QN77S85HAE 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.
- 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 QN77S85HAE cheap to run?
Not especially. At $50 a year it ranks #133 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 QN77S85HAE cost per month?
Roughly $4.19/mo, spreading the $50/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 271 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $50 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Samsung QN77S85HAE for its size?
37th 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.
