Sourcing fee model calculator: percentage fee, built-in markup or flat plan
Enter one factory order and compare three ways of paying for sourcing help: a percentage fee with a minimum, a price with the margin built into the unit price, and an open-book flat monthly plan. Every figure is your own assumption; the tool only does the arithmetic.

How the numbers are calculated
- Percentage fee route = order value + domestic freight + max(order value x fee %, minimum fee) + handling % x (order value + domestic freight + fee) + inspection + payment.
- Built-in markup route = order value x (1 + margin %) + domestic freight + inspection + payment.
- Open-book flat plan route = order value + domestic freight + plan fee x months + inspection + payment.
What this tool does not do
ChinaPayCheck is not a freight forwarder, customs broker, bank, escrow service or law firm. The calculators run in your browser on the figures you enter; nothing is sent anywhere, and the results are arithmetic, not quotes or advice.
To check the company behind a quote before paying, send the PI and the payment instruction to Free Triage (USD 0). Ongoing sourcing runs on flat monthly workspace plans with no percentage sourcing fee.
