Watch profit calculator
The gap between your buy price and sale price is only the starting point. Enter your costs to see what could remain.
Enter a watch and a resale scenario
Calculate profit, break-even and a maximum purchase price using your own assumptions. Nothing here predicts a sale or authenticates a watch.
How watch resale profit is calculated
Profit equals resale proceeds minus the watch’s purchase price, purchase taxes and duties, inspection and service, selling fees, delivery and your contingency reserve. Margin divides that profit by the resale price. Return on acquisition cost divides it by purchase price plus incoming costs and service.
Break-even divides fixed modeled costs by one minus the effective selling-fee rate. Maximum buy subtracts your target profit and every other modeled cost from the sale proceeds after percentage fees.
Which selling fee should I enter?
Use the effective fee for your actual marketplace, country and seller account. For example, Chrono24 lists a 6.5% commission for private watch sellers. eBay’s fees vary by category, price tier and account, and its fee base can include shipping and sales tax. This calculator does not automatically reproduce those fee schedules: convert them to an effective rate or enter the quoted fee as a fixed amount with a zero percentage.
Can this tell me what a watch will sell for?
No. You supply the resale-price assumption. Check recent comparable evidence in the valuation guide and keep asking prices separate from confirmed sale prices. This calculation does not include income tax, financing or the value of your time unless you include them in your cost assumptions.
