Pottery Profit Margin Calculator: Margin and Markup Per Piece
Work out the profit margin, markup, and gross profit on a handmade pottery piece from its price and material cost — the numbers that tell a potter whether the pricing covers clay, glaze, firing, labor, and the inevitable losses.

How the numbers shift across typical situations for this calculator:
| Scenario | Profit margin | Markup | Profit |
|---|---|---|---|
| $40 price · $12 cost (70%) | 70.00% | 233.33% | $28.00 |
| $25 mug · $6 cost | 76.00% | 316.67% | $19.00 |
| $120 large piece · $30 cost | 75.00% | 300.00% | $90.00 |
| $30 price · $18 cost (thin) | 40.00% | 66.67% | $12.00 |
How This Calculator Works
Enter your selling price and the material cost per piece (clay, glaze, and the per-piece share of kiln firing). The calculator returns gross profit, the margin as a percent of price, and the markup as a percent of cost. Keep your labor and studio overhead out of the material cost — the margin has to cover those.
The Formula
Profit Margin and Markup
Markup = (Revenue − Cost) / Cost × 100 — the same profit measured against cost instead of revenue
Worked Example
A piece priced at $40 with $12 of materials earns $28 gross profit — a 70% margin and a 233% markup. Pottery shows strong material margins, but the gross profit has to pay for substantial labor (throwing or hand-building, trimming, glazing, and multiple firings with drying time between), studio and kiln overhead, and the pieces lost to cracking or glaze defects in firing. Potters commonly use high markups precisely because the process is slow, multi-stage, and has a real failure rate.
Key Insight
Pottery is a craft where labor and process losses dominate cost, so material margin alone badly understates what a piece really costs to make. A single piece passes through many time-consuming stages — forming, drying, bisque firing, glazing, glaze firing — often over a week or more, and a fraction of pieces crack, warp, or fail in the kiln, meaning the successful pieces must cover the losses. Three pricing principles: charge for your labor at a fair rate on top of materials (a common formula is materials + (hours × studio rate) + overhead and profit), fold in studio overhead (kiln energy is significant, plus rent, tools, and shelf space), and price for breakage — if 1 in 10 pieces fails, your sellable pieces must absorb that. Don't anchor to mass-produced ceramics; handmade pottery sells on uniqueness, craftsmanship, and the maker's story. Add selling costs (marketplace fees, market tables, and shipping fragile, heavy items) before celebrating the margin. A 70% material margin is healthy, but the business only works when the price covers materials, your time, overhead, breakage, and fees — with profit on top.
Frequently Asked Questions
How is pottery profit margin calculated?
Gross profit is the price minus material cost; margin is gross profit divided by the price, times 100. A $40 piece with $12 of materials has $28 profit — a 70% margin and a 233% markup.
What's the difference between margin and markup?
Margin is profit as a percent of the selling price; markup is profit as a percent of cost. The same $28 on a $12 cost is a 233% markup but a 70% margin. Potters often quote the bigger markup, but profitability is driven by margin after all costs.
Should labor and firing be in the cost?
Include the per-piece share of kiln firing/energy in materials, but keep your labor out of it — labor is usually the biggest real cost in pottery. After computing the material margin, add a fair hourly rate for the forming, trimming, glazing, and handling time each piece requires across multiple stages.
How do I price for pieces lost in firing?
Pottery has a real failure rate — pieces crack, warp, or have glaze defects. If, say, 1 in 10 pieces fails, your sellable pieces must cover the cost of the lost ones. Build that breakage rate into your pricing so the successful pieces carry the failures, or your effective margin will be lower than it looks.
What costs reduce the margin when selling?
Studio overhead (kiln energy, rent, tools, shelving), and selling costs — marketplace fees, craft-fair tables, and shipping fragile, heavy ceramics. Build cushion into the gross margin so each piece still profits after these real costs, rather than pricing on clay and glaze alone.

Methodology & Review
Gross profit is the price minus the material cost; margin is gross profit as a percent of the price; markup is gross profit as a percent of cost. Material cost should include clay, glaze, and per-piece firing/kiln energy; it excludes your labor, studio overhead, and the cost of pieces lost in firing, which the margin must also cover.
