Projector TCO Calculator — Lamp vs Laser

Free total-cost-of-ownership calculator that compares a typical lamp projector (mid-tier 4K, replacement bulbs every ~3,000 hours) against a typical laser projector (slightly higher purchase price, no bulb replacements, ~15% less power consumption) over your chosen ownership period and usage. Includes electricity at your local kWh rate. Many laser projectors break even at 4–6 years and run cheaper afterwards — but heavy daily use accelerates that crossover.

How to use

1
Period

5 years is typical home consumer hold time; 7–10 for enthusiasts.

2
Hours per year

500 ≈ 1.5 h/day. 1,500 ≈ 4 h/day. Be honest about your usage.

3
Wattage

Check your projector's power-draw spec sheet. Default 280 W matches typical 4K lamp models.

4
Electricity rate

Enter the price you actually pay per kWh — check your latest bill for accuracy.

FAQ

Why does laser typically win on long ownership?

No replacement bulbs (a recurring cost every ~3,000 hours), and laser engines run 10–20% more efficiently. Over 7,500+ total hours those savings usually outpace the upfront price gap.

When does lamp win?

Short ownership (≤3 years), low usage (<300 hours/year), or very cheap electricity. The lamp's lower purchase price wins before its replacement cycle starts hurting.

What about lamp brightness degradation?

Lamp brightness drops ~30% over its rated life. This calc doesn't price that in directly — but it's a real cost in image quality. Lasers degrade ~5% over 30,000 hours.
