A 14k gold chain costs you $22, you charge $85, and the weld takes 12 minutes. On paper you made $63. In your books you also bought a $1,800 welder, paid $200 in liability insurance, wasted 18 inches of chain learning the clasp, and spent two hours on Instagram trying to book the next appointment — none of which that $63 covered.
Permanent jewelry — welded bracelets, anklets, and necklaces where the clasp is welded shut — looks like a high-markup impulse buy, and it is. The material markup is real, 300–600% on chain and charms. The profit is not, unless you cost the weld, not just the chain, and track inventory that leaves by the inch.
Per-Weld Costing: The Unit Is the Weld, Not the Bracelet
Most studios price by chain length or by design ("$65–$95 per bracelet"). That hides the work. A better unit is the weld event, because every revenue event consumes the same constrained resources:
- Chain and findings: Cost per inch, including waste. Chain is sold by the foot or by the spool; you cut by the inch. A 14k gold-filled chain at $18 per foot is $1.50 per inch. A 7.5-inch bracelet plus a 0.5-inch jump ring is 8 inches = $12.00 in chain, plus a $3 charm if chosen.
- Consumables: Argon gas per weld, tungsten electrode wear, cleaning supplies, and the small but real cost of the lease or depreciation on the welder. Argon at $80 per fill over ~200 welds is $0.40 per weld.
- Labor: The welder's time, including consultation, sizing, and aftercare, not just the arc. If a weld takes 12 minutes of hands-on time but the appointment slot is 20 minutes including customer interaction, labor is 20 minutes × loaded rate. A $22/hour loaded rate × 0.33 hour = $7.33.
- Overhead allocation: Booth or studio rent, appointment software, payment processing, and insurance, allocated per appointment slot. If your monthly fixed costs are $1,800 and you do 120 welds, overhead is $15 per weld.
Total cost for an $85 welded bracelet with a charm: $15.00 chain and charm + $0.40 gas + $7.33 labor + $15 overhead = $37.73. Gross profit $47.27, margin 56%. Without the overhead allocation, you thought margin was 82% and wondered why the second month's rent was still hard to make.
Inventory by the Inch and the Link
Chain inventory is where shrinkage hides. You buy by the foot, you sell by the inch, and you practice, rework, and waste in between. A spool that should yield 40 bracelets yields 36 because of miscuts and practice welds.
Track inventory as an asset, then expense as used: Buying a $360 spool of gold-filled chain is Dr Inventory — Chain $360 / Cr Cash $360. Each weld consumes Dr COGS — Chain $12.00 / Cr Inventory — Chain $12.00. Do not expense the spool at purchase — that understates next month's margin and overstates this month's.
Weigh and measure waste: Keep a small jar for clippings and miswelds, weigh it monthly, and write off the loss: Dr Inventory Shrinkage Expense / Cr Inventory — Chain. If shrinkage exceeds 5% of chain cost, your pricing must absorb it or your technique must improve.
Charm and chain mix matters: A $6 sterling charm on a gold-filled chain has a different margin than a plain chain. Track COGS per SKU or per design, not just per weld, to see which designs to promote.
Pricing That Covers the Weld and the Waiting
Demand for permanent jewelry is event-driven — pop-ups, markets, weddings, and appointments that don't happen if you don't market. Your price must cover the 20 minutes of welding and the 40 minutes of waiting.
Build the price from cost, not from the market: Starting from the $37.73 cost above and a 60% target gross margin, price = $37.73 / (1 − 0.60) = $94.33, which you might round to $95. That is the price for that design, in that volume, with that overhead.
Offer a ladder, not a single price: Plain chain at $65, chain with charm at $85–$105, double chain or anklet at a premium. Each step has its own COGS and its own labor — don't assume the charm addition is pure profit.
Batch the overhead: At a pop-up you pay a $150 booth fee. If you do 18 welds, that is $8.33 per weld. At a slow market with 7 welds, it is $21.43. Your books should show margin by channel — studio appointments vs. markets — so you know which popup is worth the drive.
Compliance and Liability Costs Most Welders Forget
- Bloodborne pathogen training: Many jurisdictions require it for any service that breaks skin, even with a weld. The course fee and annual renewal are compliance costs, not optional marketing.
- Liability insurance: A jeweler's block or general liability policy that covers permanent jewelry and off-site pop-ups. Allocate the annual premium per weld.
- Sales tax: Welded jewelry is tangible personal property, taxable in most states. If you also charge a separate labor fee, some states tax the full charge as a sale of property. Don't split labor to avoid tax without confirming with your state revenue department.
- Age and consent: Some venues require parental consent for minors. The disclosure form is a compliance asset — keep it.
Keep Your Finances Organized From Day One
Permanent jewelry feels like a craft until rent is due. Bookkeeping by the weld, inventory by the inch, and margin by channel turn a high-markup idea into a business that pays its welder, its rent, and its chain supplier on time.
Beancount.io keeps that precision in plain text — every inch of chain as inventory, every weld as a transaction with labor and overhead, and every market as a value stream you can diff. Get started for free and price the next bracelet like a business, not a guess.
