About incandescent bulb running costs
Incandescent bulbs turn most of their power into heat, not light, which makes them 6 to 8 times as costly as LEDs.
Typical sizes: 40 W, 60 W, 75 W, 100 W.
How to spend less: Replace it with a 9 W LED and keep the same brightness.
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average in Alabama. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
