A gap between the asking price and resale price is only the start. Work out what remains after fees and costs, then find the most you can pay for your target return.
Start with the hypothetical example below, then enter your own numbers. All amounts are in USD.
What you would pay for the watch.
Your expected sale price, before selling fees.
Your combined marketplace and payment fee rate.
Total shipping and insurance you expect to pay.
Service, authentication, purchase tax, and contingency.
Your target return on purchase price plus fixed costs.
The numbers after costs
Estimated net profit
$1,000.00
11.9% ROI on $8,400.00 of cash cost.
Calculated from your assumptions. Figures are rounded for display; the maximum buy price is rounded down to the nearest cent.

Three ways the margin changes. Start with a hypothetical $8,000 purchase, $10,000 resale, 6% selling fee, $150 shipping and insurance, and $250 service and other costs. Then change one assumption at a time.
| Scenario | Net profit | ROI on cash invested | Max buy for 12% ROI |
|---|---|---|---|
| Starting assumptions$10,000 resale; $250 service and other costs | $1,000 | 11.90% | $7,992.85 |
| Resale assumption falls by 10%$9,000 resale; all other inputs unchanged | $60 | 0.71% | $7,153.57 |
| Service and other costs rise by $500$750 service and other costs; resale stays at $10,000 | $500 | 5.62% | $7,492.85 |
Profit and ROI above assume you pay $8,000 in every case. The maximum buy price is a separate purchase ceiling for a 12% target return under each row's assumptions, rounded down to the nearest cent.
These fixed examples do not change with your inputs and describe no actual watch, market valuation, or available deal. The 6% fee is hypothetical. Profit is before income tax and any costs not entered.
These calculations use the assumptions you enter. The starting example is hypothetical and does not describe an actual watch, market price, or available deal.
An asking price is not a completed sale. Before buying, check comparable watches with the same reference, condition, and box and papers. Use a resale assumption you can support, and allow for negotiation and time to sell.
Enter the fee rate for your actual selling channel. This tool uses one percentage of the resale price; tiered fees, minimum fees, and tax treatment can change the result. Add applicable purchase tax, authentication, and other fixed expenses under service and other costs.
