How to Calculate Selling Price

The basic idea

A sustainable price has to cover three things: the direct cost of producing the item, a fair share of overhead, and a profit margin. If any one of those is missing, the price isn't doing its job.

Step 1 — Calculate the variable cost per unit

Add up everything that goes into producing one unit: materials, packaging, direct labour, payment processing, per-unit shipping.

Step 2 — Add a share of overhead

Take your monthly operating expenses and divide by the number of units you reasonably expect to sell. That's the overhead each unit must carry.

Step 3 — Decide your target margin

Pick a target gross margin appropriate for your industry (e.g. 60% for a café, 40% for retail).

Step 4 — Compute the price

Practical example

A small ceramics maker:

• Variable cost per mug: $6 (clay, glaze, packaging, shipping prep)
• Monthly overhead: $1,500 (studio rent, utilities, software)
• Expected sales: 150 mugs/month → overhead per unit = $10
• Target gross margin: 50%

Step 5 — Check the market

Compare against competitors. If your math says $32 but similar mugs sell at $20, you have a choice: lower costs, lower the target margin, differentiate enough to justify the price, or rethink the product.

Common mistakes

• Forgetting overhead. "Cost + 20%" pricing usually loses money.
• Confusing markup with margin. See Markup vs Margin.
• Pricing once and never revisiting. Costs change — prices should too.
