LED Savings Calculator
Wondering if switching to LED bulbs is worth it? Enter your current bulb count, wattages, daily usage, and electricity rate to see the annual and 10-year savings, plus the environmental benefit of reduced CO2 emissions.
LED bulbs use about 75-85% less electricity than incandescent bulbs for the same light output. A standard 60-watt incandescent can be replaced by a 9-watt LED that produces the same 800 lumens. The electricity savings add up quickly, especially across an entire home.
The cost formula is: Annual Cost = Bulbs x Watts x Hours/day x 365 days / 1000 x $/kWh. The CO2 reduction is calculated using the US average grid emission factor of 0.92 pounds of CO2 per kilowatt-hour.
Beyond electricity savings, LED bulbs last 15,000-50,000 hours compared to 1,000 hours for incandescents, meaning you also save on replacement bulb costs. A typical LED bulb pays for itself in energy savings within 3-6 months of use.
