Inputs used by this tool
The calculator displays the following fields. Your exact inputs depend on the selected tool and its available options.
- Days Out of Stock
- Average Daily Units Sold
- Profit per Unit ($)
Calculation method and formula
The tool's registered calculation explanation is:
Lost Revenue = Days Out of Stock * Daily Sales Velocity * Selling Price. Plus 20% estimated PPC recovery tax.
The result depends on the values you enter and the assumptions built into the tool. Where marketplace fees, carrier prices or tax rules apply, confirm the latest official figures before relying on the estimate.
Practical tips before you use the result
- Use current figures from your Seller Central reports, supplier quotation, invoice or other primary records.
- Keep the units consistent. Do not mix inches with centimetres, kilograms with pounds, or one currency with another.
- Test more than one realistic scenario when comparing prices, costs or campaign settings.
- Save or record the result you need before closing or refreshing the page.
- Raise prices slightly to slow sales velocity rather than running completely out of stock; maintaining listing activity protects your Best Sellers Rank (BSR).
- Pre-create an FBM fulfillment fallback template so you can ship orders merchant-fulfilled while waiting for your next FBA sea freight shipment to check in.
Use supplier quotations and current marketplace data for your inputs. Recheck minimum order quantities, prep costs, freight and payment terms before placing an order.
