Per piece: your true cost including clay, glaze, and firing, how many to sell to break even, runway with & without a salary, and when you profit. Everything updates as you type.

This is a planning estimate — not tax, accounting, or investment advice. "Units to break even" assumes selling only that product; the blended row assumes equal units. No data leaves your browser.
This free calculator shows potters and ceramic artists exactly how many sales it takes to break even and start making a profit — after your real costs, fees, and pricing.
Do clay, glaze, and kiln firing count per piece?
Yes — clay, glaze, and a share of firing/energy are variable costs per piece. Enter them as your per-unit cost so break-even reflects the true cost of each pot.
How do I calculate break-even for potters and ceramic artists?
Divide your fixed monthly costs by your profit per sale (your price minus the cost and platform fees of each sale). This calculator does the math for you and shows the month you turn a profit.
Is this calculator free to use?
Yes. It runs free in your browser with no account, and your numbers never leave your device. A more detailed downloadable Excel and Google Sheets version is available if you want to keep working offline.
