How Much Does It Cost to Run a Home Projector in California? (2026)
Lamp projectors draw 250 to 400 watts, several times a TV of similar picture size. LED and laser projectors use a third to half as much and their light sources last far longer.
A typical home projector (250 W) costs $0.087 per hour, or about $5.25 per month at 2 hours a day in California. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (100 W) | $0.035 | $0.070 | $2.10 | $25.55 |
| Typical (250 W) | $0.087 | $0.17 | $5.25 | $63.87 |
| High (400 W) | $0.14 | $0.28 | $8.40 | $102.20 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 2 h/day ≈ 182 kWh per year.
In California, with electricity at $0.35 per kWh (source: EIA Table 5.6.A, 2026-06), a typical home projector costs $0.087 per hour and about $63.87 per year at 2 hours a day. That is about 94% more than the US national average of $2.70 per month, because electricity in California costs $0.35 per kWh against $0.18 nationally. Each $1.00 of electricity buys roughly 11.4 hours of use.
How to lower the cost of running a home projector
- Use eco lamp mode. It cuts power by 20 to 30 percent and extends lamp life.
- Watch in a dark room so you can run lower brightness.
- Unplug it between uses. Some models keep fans running in standby.
In standby it draws about 1 W, which adds roughly 9 kWh ($3.07) per year if it is never unplugged.
