Find out what your jewelry business actually nets after cost of goods, wages, rent, and overhead — not just what the register rings.
The case looks like money. A glass counter full of pieces marked up 3x, a register that rang $42,000 last month, gold prices climbing — and a checking account that somehow still feels tight. That gap is the whole story of jewelry retail: the price multiples are gorgeous and the operating cost structure is brutal, and the two cancel out faster than most owners expect. This calculator does the accounting nobody enjoys doing: in-store transactions, online sales, cost of goods, wages, rent, and overhead collapsed into one net profit and one margin number.
You enter Daily Transactions and Working Days Per Month, then Average Transaction ($) for in-store sales and Monthly Online Sales ($) for any e-commerce revenue. Cost of Goods Sold (%), Employee Wages, Monthly Rent, and Monthly Overhead build the expense side. The result is Monthly Net Profit, Net Margin, and an Annual Projection — numbers that tell you whether the business model is working, not just whether it is busy.
Cost of goods in jewelry: why the percentage matters more than the dollar
Jewelry businesses operate on gross margin, and that margin is set almost entirely by cost of goods sold as a percentage of revenue. A retail jewelry store typically prices at 2–4x cost for branded or designer pieces and 3–6x cost for house-made or gold/gemstone items. That produces COGS percentages in the range of 15–50% depending on product mix and sourcing. Fine jewelry with high precious metal and gemstone content tends to run 35–50% COGS; costume and fashion jewelry can be 20–30%.
The Cost of Goods Sold (%) field is where most of the margin story lives in this model. A four-point improvement in COGS — through better wholesale relationships, higher-margin product categories, or reduced waste — on a $45,000 revenue month adds $1,800 to net profit. That is not a small number in a business where total net profit might be $6,000–10,000/month. Tracking COGS by product category is how owner-operators find where margin leaks most.
Online sales as a margin lever
Monthly Online Sales ($) is entered separately from in-store transaction revenue because the economics differ. Online jewelry sales typically carry higher platform and payment processing fees (Etsy, Shopify, or similar at 3–10% of revenue) but often serve a different customer who discovered the brand through search or social media. Some jewelry makers find that online sales produce lower average ticket but higher absolute margin because there is no retail overhead to cover — no square footage, no showroom staff.
Entering online revenue separately lets you see the combined revenue base clearly. If online sales are small relative to in-store, you can model what doubling online revenue through better product photography or paid ads would do to total net profit without changing the in-store operation at all. The two streams combined give you Total Revenue, which is the base for the COGS calculation and the overhead coverage ratio.
Employee wages and the labor intensity of jewelry retail
Jewelry retail is sales-intensive — knowledgeable staff are central to the customer experience, especially for higher-priced items where trust and expertise drive the transaction. Employee Wages as a monthly expense can run from $0 for a solo operator to $12,000–20,000+ for a staffed boutique. The wage figure entered here should include all on-floor staff: sales associates, bench jewelers if on staff, and any part-time help.
Jewelry repair services, if you offer them, create a bifurcated labor picture: repair work is bench time that can be billed at high margin, while floor sales require customer-facing staff who may or may not be the same people. The calculator treats wages as a flat monthly expense, so fold all employee costs into this line for the most accurate net profit calculation.
Rent and location: the constraint that shapes everything else
Monthly Rent for a jewelry business is not just a fixed cost — it is a commitment to a specific customer volume at a specific price point. A mall kiosk at $3,500/month in rent requires far less transaction volume to cover costs than a 1,200-square-foot boutique at $6,000/month, but the boutique may have access to a customer segment willing to spend $800 on a piece rather than $80. Rent shapes the break-even transaction count, the minimum average ticket required to survive, and the customer experience you can offer.
Run the calculator at your current rent, then model what a 20% rent reduction or a move to a smaller footprint would do to monthly net profit. Some jewelry operators find that a location move to lower-cost retail or a shift toward appointment-only or online-first sales hands back a chunk of margin that retail rents had been quietly eating.
Your inventory is a savings account that might be paying you 4 percent
The Annual Projection — monthly net profit times twelve — gives you the full-year income picture at the current run rate. This figure is particularly relevant for jewelry businesses because inventory investment is high relative to other retail categories. Fine jewelry inventory can tie up $50,000–$250,000 in pieces that may turn slowly. The annual net profit figure lets you calculate inventory return on investment: if your annual net profit is $78,000 and your inventory is valued at $120,000, your net return on that inventory investment is about 65%.
That is a strong return on working capital if it is real and not a paper number propped up by slow-moving stock. If your inventory turns slowly and net profit is tight, the annual projection makes the opportunity cost visible: capital sitting in display cases that are not selling is capital not compounding elsewhere.
How to use it
- Enter Daily Transactions using your POS average over the last 90 days — blend weekday and weekend traffic for accuracy.
- Set Working Days Per Month to reflect your actual open schedule, including any seasonal closures.
- Enter Average Transaction ($) for in-store sales and Monthly Online Sales ($) as a separate line.
- Set Cost of Goods Sold (%) from your actual inventory purchase records — use last quarter's COGS as a percentage of revenue.
- Fill in Employee Wages ($/mo), Monthly Rent ($), and Monthly Overhead ($), then read Net Profit, Net Margin, and Annual Projection.
Who it's for
- Jewelry store owner evaluating a second location — An owner at $6,800/month net profit models what opening a second location with $7,500 in additional monthly overhead would require in transaction volume to maintain current earnings — and decides whether the market supports it.
- Artisan jewelry maker scaling from markets to a studio — A maker doing $12,000/month in craft fair sales considers adding a studio with $2,200/month rent — models the combined transaction and online revenue needed to cover the new overhead and shows a net positive at 22 transactions/day.
- Boutique owner diagnosing a margin decline — An owner whose net profit dropped from $9,200 to $6,100 over six months plugs in current COGS and wages and identifies that a 6-point increase in COGS from a new supplier relationship is the primary driver.
- Fine jewelry retailer planning a holiday inventory buy — An operator uses the annual projection to calculate how much net profit they will generate through Q4 and whether pre-purchasing $30,000 in additional inventory makes sense given their projected cash flow.
Key terms
- Cost of Goods Sold (COGS)
- The direct cost of the merchandise sold — purchase price for resale items, or materials and fabrication cost for handmade pieces. The primary variable expense in jewelry retail.
- Net margin
- Net profit as a percentage of total revenue. Reflects how much of every dollar in sales survives after COGS, wages, rent, and overhead are all paid.
- Inventory turn
- How many times the inventory value is sold and replaced in a given period. Jewelry typically turns 1–3 times per year in retail settings; faster turns indicate stronger sell-through and less capital tied up in unsold stock.
- Average transaction value
- Total in-store revenue divided by total transactions. In jewelry retail, this is the key indicator of customer quality and price point positioning.
Frequently asked questions
What COGS percentage should I use for a fine jewelry store?
Fine jewelry with significant precious metal and gemstone content typically runs 35–50% COGS. Fashion or costume jewelry can be 20–30%. Bridge jewelry — gold-filled, sterling silver with semi-precious stones — is often in the 25–38% range. If you carry a mix, calculate your blended COGS by dividing total product cost by total revenue over the last quarter.
How should I handle jewelry repair revenue?
Repair revenue generally carries high margin (often 60–80% gross) because the primary cost is bench labor rather than materials. If repair is a meaningful portion of your revenue, include it in your Daily Transactions or Average Transaction calculation. If you want to model repairs separately, you can add the net repair revenue to Monthly Online Sales as a proxy for high-margin non-merchandise revenue.
Does this work for a home-based or online-only jewelry business?
Yes — set Monthly Rent to $0 or a home-studio allocation and enter your total online sales in the Monthly Online Sales field. Set Daily Transactions to reflect direct retail sales at markets or pop-ups. The expense structure flexes to match your business model.
What is a healthy net margin for a jewelry retail business?
Well-run jewelry retailers typically see net margins of 12–25%. Higher margins are achievable for makers who control the supply chain — artisan jewelers who design and fabricate in-house often see 30–45% net because they eliminate the wholesale markup. Retail-only operations with full staffing and prime location rent typically land at 10–18%.
