How much does it cost to run a projector?
We've pre-filled a typical projector below. Set your electricity rate and adjust the hours to match how you use yours — the cost updates instantly.
A projector's lamp or LED engine draws 150 to 350 watts — noticeably more than the TV it's often replacing — but the reason it doesn't dominate your bill the way a TV can is that nobody runs one all day. Projectors get switched on for a movie, a game, or a slideshow, then switched off, so the wattage is high but the hours are short by nature.
That trade-off is why a projector usually lands in the same ballpark as an evening's worth of TV viewing, not a full day of it. Two hours of movie night a few times a week adds up to only a few dollars a month; it's the projector bulb's lifespan and eventual replacement cost, not the electricity, that ends up being the bigger expense over the life of the device.
What drives the cost of running a projector
- Wattage varies widely by tech and brightness: compact LED/laser mini-projectors sit near 150W, while brighter lamp-based home theater units used in bigger rooms push toward 350W
- Session length, not runtime like a fridge — a projector is typically only on for the length of what you're watching, so hours/day matters far more here than for always-on appliances
- Lamp mode (eco vs. full brightness) changes draw noticeably; eco/low-power modes can meaningfully cut wattage versus max brightness for the same content
How to cut it
- Turn it off between segments instead of leaving it on standby or idling on a paused frame — most units draw meaningful power even when not actively projecting
- Use eco or low-lamp mode for casual viewing; it cuts power draw substantially with only a modest brightness trade-off in a dark room
- Size the room correctly (blackout curtains, dimmed lights) so you're not tempted to run it in a brighter, higher-lamp-power mode than necessary
- If replacing a large TV for most viewing, remember the comparison that matters is total hours used, not wattage alone — projectors used sparingly can cost less overall
Common questions
How much does it cost to run a projector per month?
At a typical 250W and about 2 hours a day, a projector costs roughly $2.55 a month at $0.17/kWh. Set your own rate and hours above for an exact figure.

Does a projector cost more to run than a big-screen TV?
No. Even large home theater projectors typically draw far less than the TV they're mimicking on-screen size for — a 65" LED TV commonly pulls 100-200W nearly continuously during use, similar wattage to a projector, but projectors tend to get used in shorter bursts (movie nights vs. background TV), which usually keeps their total monthly cost lower.
Does a projector use electricity when it's on standby, not actually projecting?
Very little while it's off, but many projectors aren't fully off in standby — some keep a cooling fan or indicator circuit lightly powered. The wattage used in this calculator is for active projection time; unplugging or using a power strip after use avoids any standby draw entirely.
