Jewellery Cost and Selling Price Calculator

Build a price that covers production costs, percentage selling fees and the desired margin. Use invoice or quoted material costs; the tool does not supply metal spot prices or gemstone valuations.

How the calculation works

Set a cost-based jewellery price using invoiced materials, labour and overhead. The calculation allows for unrecoverable waste and a selling fee charged as a percentage of the final price.

Adjusted material cost = material cost / (1 − unrecoverable waste). Selling price = total production cost / (1 − target margin − percentage selling fee).

  1. Allow for usable material

    Divide material cost by one minus unrecoverable waste. This calculates the material spending needed to obtain the intended usable amount.

  2. Add making costs

    Add hours times labour cost, packaging and allocated overhead. Treat paid making time as a cost before calculating the profit left from a sale.

  3. Solve for selling price

    Divide production cost by one minus selling-fee proportion and target-margin proportion. Both percentages apply to final price rather than being simple cost markups.

Worked example: Commission included

Sample inputs demonstrate the method. They are not a forecast or product offer.

Materials of €50, labour of €40 and €10 packaging and overhead total €100. A 10% fee and 20% margin leave 70% of price for cost. €100 divided by 0.70 gives about €142.86.

Understanding your result

The output is a cost-and-margin scenario. It does not establish resale value, rarity, demand or what a buyer will pay for the finished piece.

Reported profit is after the entered percentage fee. An omitted fixed transaction charge or other production expense would reduce the amount actually retained.

Questions you might have

Should recoverable scrap be treated as waste?

Not at full cost if it can be reused or sold. Enter only the unrecoverable proportion or adjust the material cost for a supported recovery value.

Choosing the right inputs

Materials needed before waste allowance
Enter material cost before the waste allowance, using supported purchase prices. This is not a live metal quotation or gemstone appraisal.
Unrecoverable material proportion
Include only material that cannot be recovered, reused or credited. Required material cost is divided by the usable proportion.
Selling fee on final price
Use the selling charge as a percentage of final price. This and the target margin must leave a positive share to cover production cost.

Common mistakes to avoid

  • Do not classify recoverable scrap as a complete material loss without considering its usable or supported recovery value.
  • Do not add a percentage fee only to cost and expect it to match a charge on final selling price.

Assumptions to check

  • Use amounts in one currency and one reporting period. Results are labelled EUR; the arithmetic also works for another consistent currency.
  • Material costs come from the user’s invoices or quoted prices. No metal spot valuation or gemstone appraisal is provided.
