FAQs
What costs are included in this estimate?
The tool combines fixed monthly costs (facility, salaried labor, software, equipment, overhead, storage, inbound) with variable per-order costs (pick & pack, packaging, shipping, marketplace fees, payment processing, and returns handling).
How should I pick the period for orders?
Most merchants use a typical month. If your business is seasonal, run separate scenarios for peak and off-peak periods to understand the range.
Why is cost per order dropping when I increase volume?
Fixed costs are spread across more orders, reducing the allocated amount per order. Variable costs remain constant per order unless you adjust them.
How do percent-based fees work?
Marketplace and payment percentages are applied to your average order value. The tool adds any fixed fee component per order on top.
Can I model returns accurately?
Enter your expected returns rate and the average cost to process a return. The calculator converts that into a per-order amount.
What if some fixed costs are actually quarterly or annual?
Convert them into a monthly equivalent before entering. For example, a yearly policy of 1,200 becomes 100 per month.
How can I use this result?
Compare against your gross margin to ensure pricing is sustainable, test 3PL quotes, and plan hiring or facility changes with the sensitivity table.
