Jewelry Markup and Margin: How the Numbers Actually Work

Two numbers get used interchangeably in wholesale conversations and they are not the same number. Jewelry markup is calculated against what you paid. Margin is calculated against what you charge. Confusing them is how a shop convinces itself it is making 50% when it is making 33%. This page sets out both formulas, then works them through against the real per-piece and quantity prices on 3,656 published variants in the AdornTrade catalogue, so the arithmetic sits on actual numbers rather than a worked example.

Markup vs margin: two different formulas

The standard definitions are:

• Markup = (sale price − cost) ÷ cost
• Margin = (sale price − cost) ÷ sale price
• And they convert: margin = markup ÷ (markup + 1)

So a piece that cost $10 and sells for $20 carries a 100% markup and a 50% margin. "Keystone", the old trade shorthand for doubling cost, is a 100% markup, which is a 50% margin. A 42% markup is a 29.6% margin. The two numbers only agree at zero.

Markup on cost	Multiplier	Resulting margin
50%	1.5×	33.3%
100% (keystone)	2.0×	50.0%
150%	2.5×	60.0%
200%	3.0×	66.7%
300%	4.0×	75.0%

What the cost side actually looks like

Markup arithmetic is only as good as the cost you put into it, and wholesale jewelry pricing varies by material family far more than most first-time buyers expect. Across the five families currently published, the single-piece median runs from $1.31 to $19.28 — a spread of about 14.7 times between the cheapest and dearest shelf.

Material family	Products	Variants	Lowest, 1 pc	Median, 1 pc	Highest, 1 pc
Copper and brass	205	243	$0.72	$1.31	$4.72
Stainless steel	293	1,440	$0.14	$4.25	$31.49
Natural stone and pearl	201	380	$0.84	$4.77	$47.48
Sterling silver	207	468	$3.07	$11.12	$163.43
Moissanite in 925 silver	255	1,125	$6.16	$19.28	$136.47

The practical reading is that a single blanket multiplier across a mixed tray does not survive contact with these spreads. A 3× rule puts a $1.31 copper ring at $3.93 and a $19.28 moissanite ring at $57.84; the first is probably under-priced against what the shelf will bear and the second may be over-priced against what the customer expected to pay for silver.

What the quantity break does to the same sum

Quantity pricing moves the cost side, so it moves every margin calculated from it. Measured across all 3,656 published variants, the 3-piece price averages 93.69% of the single-piece price and the 8-piece price averages 81.21%. The spread is narrow: 91.67% to 96.15% at the 3-piece break, and 78.95% to 85.71% at the 8-piece break. Those ranges come from rounding to whole cents rather than from different rules per product.

So buying eight rather than one takes roughly 18.8% off unit cost. Held against a fixed shelf price, that is where it lands:

Family	Cost at 1 pc	Cost at 8+	Shelf at 3× the 1-pc cost	Margin buying 1	Margin buying 8
Copper and brass	$1.31	$1.06	$3.93	66.7%	73.0%
Stainless steel	$4.25	$3.45	$12.75	66.7%	72.9%
Natural stone and pearl	$4.77	$3.87	$14.31	66.7%	73.0%
Sterling silver	$11.12	$9.03	$33.36	66.7%	72.9%
Moissanite in 925 silver	$19.28	$15.66	$57.84	66.7%	72.9%

The quantity break is worth about 6.2 margin points at a 3× shelf price. That is the entire economic argument for ordering eight instead of one, and it is a smaller number than most quantity-discount pitches imply. It is worth taking when the style is proven and worth declining when it is not, because eight unsold pieces at $15.66 is $125.28 of stock that is not moving.

The costs that markup does not cover

Markup applied to the item price alone overstates what reaches the bank. Before comparing your margin to anyone's benchmark, subtract:

• Inbound freight and any import duty or tax. On small parcels this can be a material share of a $1.06 item and a rounding error on a $110.88 one, so it distorts cheap lines hardest.
• Payment processing. A few percent of the sale price, taken off the top.
• Breakage, returns and unsold stock. A 66.7% margin on the 70% of a tray that sells is not a 66.7% margin on the tray.
• Your own time on photography and listing. Fixed per style, so it penalises shallow buys of many styles.

A workable habit is to calculate your jewelry margin twice: once on item cost to compare suppliers, and once on fully landed cost to decide the shelf price. The first number tells you who to buy from and the second tells you whether to buy at all.

Setting a rule you can actually hold

Rather than one multiplier, most small retailers end up with a band: a higher multiplier on cheap, high-turn lines where the absolute cash margin is small, and a lower multiplier on expensive lines where a 3× shelf price would price the item out of the room. At our own medians, a 4× rule on copper puts a ring at $5.24 and a 2.5× rule on moissanite puts one at $48.20 — two different multipliers producing two prices a customer would recognise as reasonable, which a single rule would not have done.

One caution on the figures above. Our prices are set from supplier cost converted at the live exchange rate, so every number here moves when the rate moves; they describe the shape of the cost curve on 12 September 2026, not a quote. If you are building a pricing sheet, pull the current wholesale price list rather than copying these medians, and set your multiplier per family: the copper and brass shelf and the moissanite shelf sit 14.7 times apart, and one rule cannot serve both.
