LED Lighting Upgrade Savings Calculator
How much will you save by switching to LED bulbs? Enter your current bulb type, number of bulbs, and usage hours to calculate annual savings, payback period, and 10-year ROI.
Annual Savings
LED vs. Incandescent Energy Savings
Annual Savings = (Old Wattage - LED Wattage) x Hours/Day x 365 x Bulbs x Rate / 1,000
Wattage comparison (equivalent brightness ~800 lumens):
- Incandescent: 60W
- Halogen: 43W
- CFL (compact fluorescent): 14W
- LED: 9W
LED advantages:
- Last 15,000–25,000 hours vs. 1,000 hours for incandescent
- 75% less energy than incandescent
- Lower heat output — reduces cooling load in summer
- No warm-up time, no mercury (unlike CFLs)
