Model
Sansui LE-50KA1
Rank #35 means 34 of the 172 television models we track cost less to run each year; the 77th efficiency percentile means it uses less energy for its size than 77% of those models.
What does the Sansui LE-50KA1 cost to run per year?
At $24 a year to run, the Sansui LE-50KA1 runs cheaper than most models in its class, ranking #35 of 172 television models we track. Once capacity is factored in, its 77th efficiency percentile puts it ahead of most peers in its class. At 67.97 W in on-mode, its power draw is a direct input into that running-cost figure.
Immediately around it on the leaderboard, the Sansui LE-40VA1 at $24/yr runs a little cheaper and the Sansui LE-50VA1 at $24/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 Sansui LE-50KA1's $24/yr adds up to roughly $168 in electricity alone, before purchase price or repairs.
By the numbers
The Sansui LE-50KA1 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 $24/yr, here is what the Sansui LE-50KA1 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Sansui LE-50KA1 costs about $240. That is roughly $110 less than the class median, which would run closer to $350 over the same ten years.
How the Sansui LE-50KA1 compares
The television class we track runs from $3 to $117 a year. At $24/yr, it runs about $11 a year cheaper than the class median of $35, and it is about $21 a year more than the cheapest television to run at $3.
What drives its running cost
At 49.5 in, the Sansui LE-50KA1 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. 67.97 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. 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 Sansui LE-50KA1 cheap to run?
Yes, relatively. At $24 a year it ranks #35 of 172 television models we track, in the cheaper part of its class to run.
How much does the Sansui LE-50KA1 cost per month?
Roughly $1.96/mo, spreading the $24/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 127 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $24 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Sansui LE-50KA1 for its size?
77th percentile once size is factored in, a fairly typical result for the class.
