Is a pottery kiln expensive to run?

Fire full loads and consider overnight firing on time-of-use rates — kilns are the classic off-peak candidate. At typical use it adds about $20.05 to a monthly electric bill at the US-average rate, but that swings from $14.00 in the cheapest states to $52.15 in the most expensive.

How many watts does a pottery kiln use?

Pottery Kiln typically draws about 8,000 running watts. It's a resistive load, so its startup and running wattage are the same. Check the nameplate or label on your specific unit for its exact rating.

How much electricity (kWh) does a pottery kiln use?

At typical use (8,000 W for 0.5 hours a day), a pottery kiln uses about 4.0 kWh per day — roughly 122 kWh per month, or about 14% of what the average US home uses in a month (863 kWh). Energy used doesn't depend on your electricity rate — only the bill does.

How can I lower the cost of running a pottery kiln?

Fire full loads and consider overnight firing on time-of-use rates — kilns are the classic off-peak candidate. You can also cut the cost by lowering your electricity rate — many utilities offer cheaper off-peak hours — or simply by running it fewer hours. The calculator on this page shows how changing hours per day or your electricity rate moves the number.

How Much Does It Cost to Run a Pottery Kiln?

A kiln firing runs 8,000 watts for hours — a single cone-6 firing can add $10+ to a bill, the rare hobby load that genuinely shows up. At the US-average rate of 16.5¢/kWh, running a pottery kiln costs about $20.05/month ($240.61/year) at typical use. Adjust the watts, hours, and your rate below for your exact number.
