What did the last stockout actually cost?
Four sliders, your numbers, your arithmetic. This page asserts nothing about your business that you did not type into it: every figure below is computed from your inputs, with the arithmetic shown, and one fixed assumption that is labelled where it is used.
Your inputs stay in this browser. Nothing you enter here is sent to Volumetris.
The two costs of a dark listing.
Margin stops the day the listing goes dark, and it does not restart at full speed. Set the four inputs to your last real stockout, or the one you can feel coming.
The recovery stretch is yours to estimate: how long rank and conversion took to climb back after your last restock. It is counted at half speed below, a fixed assumption you can scale in your head.
Daily revenue, times margin, times the dark days. The clean part of the bill.
Your recovery stretch, counted at half the normal rate: the listing is live again, the momentum is not.
One SKU, one incident. Multiply by the bestsellers that went dark in the same season, if that is your situation.
On your lead time, the decision that prevented this was due 75 days before the first dark day. That week, not stockout week, is where the plan had to exist.
Lead time is a path, not a number: production, inland, port, ocean, receiving. The 23-stage model in the build computes the whole path from your own chain.
The bill is an argument for a calendar.
Nothing above is a claim about the future. It is the arithmetic of the last incident, and its only job is to price the alternative: a weekly rhythm where the counts get reconciled, the lead times get re-checked, and the reorder decisions get made before the order-by dates pass.
How the weekly cycle runs
Build once, then the plan lands before a 30-minute call, every week. The mechanics, end to end.
Why a tool alone does not close it
Software does the arithmetic. The failures live in the inputs and the follow-through. What the build installs.
The documented record
Every proof number this site uses, traced to a documented catch, with the limits stated. The working record.
