Digital Signage Power Consumption and Running Cost per Screen
A 55-inch commercial LCD is planned at about 120 W (typical band 100 to 150 W). The formula is kWh = W × hours × days ÷ 1,000. At 12 hours a day that is 525.6 kWh a year, about $75 at the US average commercial rate of $0.1419 per kWh (EIA, June 2026), and about $149 a year at 24/7. A Raspberry Pi or Android stick adds only $3 to $5 a year. Fleet totals at 12 hours a day: 10 screens about $746, 50 about $3,729, 100 about $7,458. Scheduling screens off overnight is the biggest saving: going from 24 to 12 hours halves the bill.
This page is the per-screen calculator and the cost tables. The longer reference on enclosures, brightness multipliers and standby is Digital Signage Power Consumption and Running Cost. The electricity method here is the same one the 2026 cost guide uses, so the numbers match.
The formula
kWh per year = watts × hours per day × days per year ÷ 1,000
Cost per year = kWh per year × rate per kWh
Example, 55-inch commercial LCD, 12 hours a day:
120 W × 12 h × 365 days ÷ 1,000 = 525.6 kWh
525.6 kWh × $0.1419 = $74.58 a year ($6.22 a month)
Swap in your own rate:
Cost per year = 525.6 kWh × (your rate in $ per kWh)
e.g. at $0.30/kWh: 525.6 × 0.30 = $157.68 a year
Which watt figure to use. Use the spec sheet's "typical" or "on mode" power, not the maximum. The maximum is the power supply rating at full brightness with every feature on; actual draw is usually well below it. ENERGY STAR listings report on-mode power from a standard test, good for comparing models.
Which rate to use. The US average commercial rate was 14.19 cents per kWh in June 2026 and 14.53 cents in July 2026 (EIA Electric Power Monthly, Table 5.3); monthly values in 2026 so far range from about 13.5 to 14.5 cents. This page uses 14.19 cents to stay consistent with the cost guide. Your own bill's rate, including delivery charges, is the right number.
Typical watts by display and player
Planning ranges for normal indoor brightness, with published data points beside them. Treat the ranges as starting points and replace them with your model's spec sheet.
Displays
| Display | Consumer TV, typical on | Commercial LCD, 500 to 700 nits, typical | Planning figure used below |
|---|---|---|---|
| 43-inch | 50 to 90 W | 60 to 110 W | 80 W |
| 55-inch | 70 to 130 W | 100 to 150 W | 120 W |
| 65-inch | 90 to 170 W | 120 to 200 W | 160 W |
| 75-inch | 120 to 220 W | 160 to 260 W | 210 W |
| 55-inch window display, 3,000 nits | not applicable | 450 W (Samsung OM55B, maker's figure) | 450 W |
| Indoor LED video wall, 600 to 700 nits | not applicable | about 160 to 180 W/m² average, 460 to 540 W/m² maximum | 180 W per m² |
Published reference points we checked:
| Model | Size and brightness | Power | Source |
|---|---|---|---|
| Philips 32BDL3751T | 32-inch, 328 nits max | 27.0 W on mode, 0.53 W sleep | ENERGY STAR listing |
| Samsung QH75C | 75-inch, 600 nits max | 168.6 W on mode, 0.5 W sleep | ENERGY STAR listing |
| Samsung QM98C | 98-inch, 450 nits max | 152.0 W on mode, 0.5 W sleep | ENERGY STAR listing |
| Samsung OM55B | 55-inch window, 3,000 nits | 450 W operating, 0.5 W standby | Samsung specifications |
| Absen KL3 | Indoor LED, 700 nits max | 182 W/m² average, 540 W/m² max | Absen spec via LED Wall Central |
| Absen A2712 | Indoor LED, 600 nits max | 158 W/m² average, 464 W/m² max | Absen spec via LED Wall Central |
The pattern: brightness and panel area drive watts. A 98-inch panel at 450 nits can draw less than a 75-inch panel at 600 nits, and a 3,000-nit 55-inch draws roughly three to four times a standard 55-inch. See the brightness guide before paying for nits you do not need.
Players
| Player | Typical playback draw | Rated supply (ceiling) | Cost a year at 12 h/day |
|---|---|---|---|
| Raspberry Pi 5 | about 5 to 8 W | 5 V / 5 A USB-C (27 W official supply) | about $3 to $5 |
| Raspberry Pi 4 | about 5 to 8 W | 5 V / 3 A USB-C (15 W official supply) | about $3 to $5 |
| Android TV stick or box | about 3 to 6 W | small USB or barrel supply | about $2 to $4 |
| Chromebox / ChromeOS Flex mini PC | about 10 to 18 W | varies by model | about $6 to $11 |
| Windows mini PC (NUC class) | about 15 to 35 W | varies by model | about $9 to $22 |
| Display with built-in player | 0 W extra | not applicable | $0 |
The player is a rounding error next to the screen: one hour less screen time a day saves more than swapping a mini PC for a Pi.

Fleet examples
55-inch commercial LCDs at 120 W, display only, $0.1419 per kWh. Add about $3 a year per screen at 12 hours for a 5 W stick ($777, $3,885 and $7,769 for the three fleets).
| Fleet | 8 h/day | 12 h/day | 24 h/day | Saving, 24 h to 12 h |
|---|---|---|---|---|
| 10 screens | $497 | $746 | $1,492 | $746 |
| 50 screens | $2,486 | $3,729 | $7,458 | $3,729 |
| 100 screens | $4,972 | $7,458 | $14,917 | $7,458 |
The 12-hour column is the same as the cost guide's electricity line. On reused TVs at $3 per screen per month of software, electricity is the largest running cost, larger than the software.
Standby, ENERGY STAR and scheduling
- Standby is close to free. ENERGY STAR's Version 6.0 displays specification set a maximum sleep-mode draw of 0.5 W for all displays, and the signage panels above list 0.5 W. A screen asleep for 12 hours a night uses about 2.2 kWh a year, about 31 cents.
- ENERGY STAR listings are a comparison tool. The public product finder lists certified signage displays with on-mode power, sleep power and maximum luminance, so two candidate models can be compared on the same test.
- Schedule the screen, not just the content. Turning a 120 W screen off for the 12 hours the venue is closed saves about $75 a year per screen. Going down to 8 hours saves about $99 per screen against 24/7. Panel life is rated in hours, so the same schedule also stretches the replacement cycle.
- Let the light decide brightness. An ambient light sensor dims the backlight when the room is darker, which cuts watts on every screen that does not face the sun.
In DigitalSignage.com, content scheduling and dayparting are part of the free plan, so playlists can end at closing time. Powering the panel itself off is set in the display's own on/off timer or energy settings.

Frequently asked questions
How much electricity does a digital signage screen use?
Plan on about 120 W for a 55-inch commercial LCD at normal indoor brightness, within a typical band of 100 to 150 W. At 12 hours a day that is 525.6 kWh a year, about $75 at the US average commercial rate of 14.19 cents per kWh (EIA, June 2026). At 24 hours a day it doubles to about $149. The panel's spec sheet is the real number.
How much does it cost to run a digital sign 24/7?
About $149 a year for a 55-inch commercial LCD at 120 W and 14.19 cents per kWh, against about $75 at 12 hours a day. A 75-inch panel planned at 210 W is about $261 a year around the clock, and a 3,000-nit 55-inch window display at 450 W is about $559 a year.
How much power does a Raspberry Pi use as a signage player?
A few watts in playback, roughly 5 to 8 W for a Raspberry Pi 4 or 5, which is about $4 a year at 12 hours a day and 14.19 cents per kWh. The Pi 5's official supply is rated 5 V at 5 A (27 W), but that is a ceiling for peripherals and peaks, not normal draw. The display uses 15 to 25 times more.
How do I calculate digital signage electricity cost?
kWh = watts x hours per day x days / 1,000, then cost = kWh x your rate per kWh. For a 120 W screen at 12 hours a day for 365 days: 120 x 12 x 365 / 1,000 = 525.6 kWh, and 525.6 x $0.1419 = $74.58 a year. Replace $0.1419 with the rate on your own bill.
How much power does an LED video wall use per square metre?
Indoor LED cabinets around 600 to 700 nits list roughly 160 to 180 W per square metre on average and 460 to 540 W per square metre at maximum, based on Absen KL3 and A2712 specifications. Average depends on content: bright, white-heavy content runs toward the maximum. Outdoor LED is much higher; use the maker's sheet.
Does turning screens off at night save money?
Yes. Cutting a 120 W screen from 24 to 12 hours a day saves about $75 a year at 14.19 cents per kWh, and cutting to 8 hours saves about $99. For 50 screens, going from 24 to 12 hours saves about $3,729 a year. Commercial panels draw about 0.5 W in standby, so off time costs almost nothing.
Do commercial displays use more power than consumer TVs?
Per inch, at the same brightness, they are broadly similar; the difference is that commercial panels are often brighter and run longer hours. A 500 to 700 nit commercial panel draws somewhat more than a 300-nit TV of the same size, and a high-brightness window display draws several times more. Hours per day matter more than the badge.
What does ENERGY STAR mean for a signage display?
ENERGY STAR certifies signage displays and lists their measured on-mode power, sleep power and maximum luminance in a public product finder. Since the Version 6.0 displays specification, sleep mode may draw at most 0.5 W. Listings are useful for comparing models, but the on-mode figure is measured under a standard test, so plan with the spec sheet's typical figure.
