Model
Sansui LE-43KA1
Rank #17 means 16 of the 172 television models we track cost less to run each year; the 94th efficiency percentile means it uses less energy for its size than 94% of those models.
What does the Sansui LE-43KA1 cost to run per year?
The Sansui LE-43KA1 costs about $15 a year to run and sits near the top of the cheapest-to-run leaderboard, rank #17 of 172. Efficiency-wise, once capacity is accounted for, it beats 94% of the class, a solidly strong result rather than a size-driven fluke. At 45.14 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-32VA1 at $12/yr runs a little cheaper and the Philips 43HFL4518U/27 at $17/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-43KA1's $15/yr adds up to roughly $105 in electricity alone, before purchase price or repairs.
By the numbers
The Sansui LE-43KA1 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 $15/yr, here is what the Sansui LE-43KA1 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-43KA1 costs about $150. That is roughly $200 less than the class median, which would run closer to $350 over the same ten years.
How the Sansui LE-43KA1 compares
The television class we track runs from $3 to $117 a year. At $15/yr, it runs about $20 a year cheaper than the class median of $35, and it is about $12 a year more than the cheapest television to run at $3.
What drives its running cost
At 42.5 in, the Sansui LE-43KA1 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. At 45.14 W on-mode (the class spans 9.3 to 343.5 W), its power draw is what ENERGY STAR actually measured to produce this running-cost figure; brightness settings move that wattage more than screen size alone.
- 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-43KA1 cheap to run?
Yes, relatively. At $15 a year it ranks #17 of 172 television models we track, in the cheaper part of its class to run.
How much does the Sansui LE-43KA1 cost per month?
Roughly $1.27/mo, spreading the $15/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 82 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $15 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Sansui LE-43KA1 for its size?
94th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
