Watch deal profit margin calculator

This is a profit margin calculator for watch dealers, written in dealer math. Enter the basis, the landed cost, any parts or service, and the sold price, and it returns total cost, gross profit, gross margin, markup, and break-even. On a consignment or memo watch, the owner's payout replaces the basis. No sign-up, nothing saved.

Break-even price

Break-even is the floor: your full cost in stock mode, or the owner's payout plus your costs on consignment. Sell below it and you have paid to move the watch.

Target margin

A target margin adds two rows: the sold price that produces it, and the most you can pay the seller and still hit it, after landed cost and parts or service.

Questions
What's the difference between margin and markup?Margin is gross profit divided by the sold price. Markup is gross profit divided by cost. Same dollar profit, different base. On the flip above, $700 of gross profit is an 8.3% margin and a 9.1% markup.
What does basis mean?Basis is what you paid the seller for the watch. Landed cost is what it cost to get it in hand: shipping, duties, insurance, authentication. Parts or service is what you spent to make it sellable. Together they are your cost of goods, the COGS in the results.
How does a consignment or memo deal change the math?You don't own the watch, so there is no basis. The owner's payout and any parts or service come off the sold price, and what is left is your gross profit. The math is the same whether the watch is on consignment or out on memo.
Is this gross margin or net margin?Gross. This calculator stops at what the deal itself made, before the business's overhead: rent, payroll, insurance, marketing. Net margin is a company number that comes from your books.
This calculator is the free version of the margin math on the Movement OMS deal screen. On a deal record, basis, sold price, and gross profit sit next to the terms and payments, and the close posts to QuickBooks. Same numbers, already on the deal.
