Watt rating of the kiln (in
watts)
Look at the manufacturing plate. The watt rating of your
kiln will be between 1000 and 20000 (small kilns near 1000, large
near 20000). For single phase kilns, you can calculate the
watts by multiplying the volts x amps.
Cost of electrical power (in cents per kilowatt-hour)
The rate you pay your utility for electricity,
normally between 10 and 25 cents (per kilowatt-hour). Find
your latest utility bill and the number will be on there, or
contact your local utility office.
Note: This page uses rather simple math and a number
of assumptions to arrive at the given answer. The kiln's
construction, slow vs. fast firing, size/shape of kiln, studio
environment, etc, will all impact this number. That said, this is
still a decent number to use for budgeting the cost of firing your kiln.
