## What is Permanent Jewelry Quick COGS?

Permanent Jewelry Quick COGS is the fast, fully offline cost and margin calculator built for permanent-jewelry artists who buy chain by the foot or meter and weld bracelets, anklets, and necklaces at pop-ups.

Open it beside the welder and answer, in seconds: what did this piece cost, what should I charge, and what remains after the costs I chose to include?

THE CALCULATOR — UNLIMITED, FOREVER
• Convert chain cost per foot, per meter, or per spool into cost per inch and per centimeter.
• Bracelet, anklet, necklace, and custom lengths, in inches or centimeters.
• Wastage allowance and the exact chain length consumed.
• Charm, connector, clasp, and other component lines.
• Optional booth allocation, card fee, and re-weld allowance.
• Check a charge you have in mind, or solve the minimum charge for a target margin.
• Material COGS, total economic cost, break-even, estimated profit, and margin — with every substituted formula shown.
• One calculation is auto-saved and restored. No account, no counter, no network.

INVENTORY, QUOTES & POP-UP EVENTS
• Chain and component inventory tracked to the inch with weighted-average cost and low-stock alerts.
• Saved quotes with immutable snapshots you can revise anytime.
• Pop-up events: record each sale against your real stock, then see revenue, costs, and event profit.
• CSV export for events, sales, inventory, transactions, and quotes.

PRIVATE BY DESIGN
No account, no ads, no analytics, no tracking, and no developer-operated network. Your business data stays in a protected file on your device.

This app is a planning and recordkeeping aid, not accounting, tax, or business advice, and it never recommends a market price.
