JEWELLERY INVOICE AUDIT
See exactly how much of a jewellery quote is gold—and how much is not
Enter the net gold-alloy weight, fineness and the jeweller's written making-charge method. The calculator converts percentage, per-gram and flat charges into one comparable invoice, then separates the discount, stones, other charges, user-entered tax and optional metal-only buyback.

Separate alloy weight from pure-gold value
Enter the billable gold-alloy weight after excluding stones and other non-gold parts. Fineness converts that alloy weight into fine gold.
Translate the jeweller's pricing method into one comparable cost
The making-charge field starts blank because GoldObserve does not invent a market average. Enter the exact written rate or amount.
User-entered estimate only. This tool does not authenticate jewellery, quote a jeweller, determine a lawful tax base or value artistic, gemstone, brand or collectible content.
THE DIRECT ANSWER
Making charges pay for manufacture; they are not gold
A gold jewellery price normally begins with the value of its fine-gold content. Making charges compensate for design, labour, tooling, finishing and production complexity. A percentage quote rises when the metal price rises even if the labour is unchanged; a per-gram quote rises with billable weight; a flat quote does neither. Converting the quote into all three forms is the fastest way to compare like with like.
Every component stays separate so a discount on workmanship cannot be mistaken for a discount on gold.
THREE PRICING METHODS
The same making charge can look very different on the price tag
The calculator reports the gross and discounted charge as a total, per billable gram and percentage of metal value. That normalization is more useful than comparing three headline labels.
WEIGHT & PURITY
Use net precious-metal weight before applying fineness
Record the item's total weight, but do not assume every gram is gold alloy.
Stones, enamel, springs and other components need a separate declared weight or value.
Ten grams of 916 alloy contains 9.16 grams of fine gold; 750 alloy contains 7.50 grams.
Fine grams × the same-time gold reference per fine gram produces the metal baseline.
The FTC's consumer guidance on gold jewellery explains that a karat mark states the proportion of gold in the alloy—for example, 18 parts gold out of 24 for 18K. Plated, filled and solid-gold descriptions are not interchangeable. This calculator is for an item whose gold-alloy weight and fineness are known; it cannot determine them from appearance.
WORKED EXAMPLE
A 20% making-charge discount is not a 20% invoice discount
Consider a hypothetical 10-gram, 916-fineness item when the fine-gold reference is 8,000 currency units per gram. Fine-gold content is 9.16 grams and metal value is 73,280. A 12% making charge is 8,793.60. If the jeweller discounts that making charge by 20%, the discount is 1,758.72 and the net making charge becomes 7,034.88. Before stones, other fees and tax, the subtotal is 80,314.88—not 20% below the full invoice.
The same gross making charge equals 879.36 per billable alloy gram. A competing per-gram quote below that figure is cheaper only if the same gold weight, fineness, non-gold content, discount and other charges apply. The example demonstrates the method; it is not a current market rate.
DISCOUNT TRAPS
Ask what the discount actually touches
A large percentage can produce a modest invoice reduction because it affects only workmanship.
A lower displayed gold rate can be offset by a higher fee or an outdated price basis.
Applying a per-gram fee to total item weight may charge workmanship on non-gold components.
If wastage is charged, record its formula and amount independently instead of hiding it inside making.
A discount can change tax, but the correct base and rate depend on the actual transaction and jurisdiction.
The original labour, tax and stone price may not be recovered in a metal-only resale.
INVOICE EVIDENCE
What a strong jewellery quote should let you verify
01Description and quantity of each article.
02Net precious-metal weight after non-gold parts are excluded.
03Karat and fineness, plus the applicable hallmark or responsible mark.
04Gold reference price, currency, unit and quote time.
05Gross making-charge method, rate and base.
06Making-charge discount as an amount, not only a headline percentage.
07Stone value, hallmarking, wastage and every other charge on separate lines.
08Tax rate and base, return policy and written buyback terms.
For India, the Bureau of Indian Standards jeweller FAQ says a hallmarked-jewellery bill should identify the article, net precious-metal weight, purity in karat and fineness, and hallmarking charges. BIS also explains that HUID can be checked in the BIS Care app. These hallmark facts verify fineness disclosures; they do not set a fair making charge.
TAX BOUNDARY
The calculator accepts a rate; it does not decide the law
Tax can apply to a total transaction, selected components or a service depending on the country and facts. The field therefore starts at zero and multiplies only the visible modeled subtotal. Verify the current rate, registration status, invoice structure, exemptions and taxable base with the relevant authority or adviser. Do not copy a tax rate from an online example into a real purchase.
India's Central Board of Indirect Taxes and Customs sectoral FAQ distinguishes the sale of finished jewellery to a consumer from job work using customer-supplied gold. That distinction is one reason a generic calculator should not silently impose a single GST treatment.
BUYBACK REALITY
A purchase invoice and a resale appraisal answer different questions
The optional buyback input applies one user-entered percentage to metal value only. It intentionally excludes the original making charge, tax and declared non-gold value. The resulting gap measures the distance from the full modeled invoice to that metal-only payout. It is not a prediction of what a future buyer will offer. Brand, craftsmanship, gemstones and collectible value need an appropriate independent appraisal.
This solves the future spot reference needed to recover the invoice if the payout ratio stays unchanged.
METHODOLOGY
Every calculation can be reproduced from the invoice
GoldObserve requests XAU in the selected currency per fine troy ounce and retains the provider, observation time and freshness state. It converts that price with exactly 31.1034768 grams per troy ounce. Fineness is divided by 1,000 before metal value is calculated. The selected making-charge method produces one gross amount; the discount applies only to that amount. Declared non-gold value and other charges are added separately, then the user-entered tax rate is applied to the resulting subtotal.
No making charge, discount, stone value, tax rate or buyback percentage is supplied as a market average. When live gold data is unavailable the page does not invent a replacement. The share link and CSV preserve user inputs and outputs for comparison; they are not a quotation or appraisal.

FAQ
Gold jewellery making-charge questions
How are gold jewellery making charges calculated?
A jeweller may quote a percentage of gold value, an amount per billable gram or a flat amount. This calculator converts all three methods into a currency total and equivalent per-gram and percentage figures.
Should stones be included in gold weight?
No. Use the net billable gold-alloy weight after excluding stones and other non-gold parts. Enter any separately declared stone or non-gold value in its own field.
Does a making-charge discount reduce the gold price?
Not in this worksheet. The discount applies only to the gross making charge. Gold metal value, stones, other fees and tax remain separate unless the written invoice says otherwise.
Are making charges recovered when gold jewellery is sold?
Usually a metal-only buyback focuses on verified gold content and the buyer's payout, not the original making charge. Design, brand, gemstone or collectible value may require a different appraisal.
Does this calculator know the correct jewellery tax rate?
No. The tax field starts at zero and applies the rate you enter to the modeled subtotal. Verify both the rate and taxable base for the product, transaction and jurisdiction.
What is the difference between karat and fineness?
Karat expresses gold as parts out of 24; fineness expresses it as parts out of 1,000. For example, 22K jewellery is commonly represented as 916 fineness, while 18K is 750.
