FAQ
How accurate is this estimate?
The calculation is exact for the given inputs. Real-world variation comes from your utility’s actual rate (which varies by plan and time-of-day), your specific appliance’s efficiency, and your usage pattern. Use the customize box above to plug in your own numbers.
Where does the 14.44¢/kWh come from?
It is the Louisiana residential average from the U.S. Energy Information Administration’s Electric Power Monthly, Table 5.6.A (April 2026). See the methodology page.
How can I lower this cost?
Three high-impact moves: (1) shift heavy usage to off-peak hours if your utility offers time-of-use pricing; (2) switch to a more efficient unit (Energy Star); (3) reduce hours of use. For appliances with always-on standby draw, an inexpensive plug-in Kill-A-Watt meter often pays for itself by revealing surprise loads.
