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.

Cost = power (kW) × hours × days × your rate. Defaults are typical values — enter your appliance's actual watts (often on a label) and your real rate for a precise figure.
How much electricity does a pottery kiln use?
At 8,000 W for 0.5 hours a day, a pottery kiln uses about 4.0 kWh per day — roughly 122 kWh per month and 1,460 kWh per year. That's about 14% of the 863 kWh the average US home uses in a month. Energy use is the same everywhere — only the price per kWh changes your bill.

Measure what a pottery kiln really costs you
The estimate above uses typical wattage and hours. This load is usually hardwired or on a 240 V circuit, so a plug-in meter won't fit it; a whole-home monitor's sensors clip onto the circuit's wires inside the panel and log its real kilowatt-hours. That means working in a live panel — hire an electrician if that isn't you.
