Margin leakage calculator for wine lists
A calculator that makes invisible margin loss visible before it hurts profitability.
Estimate how much margin a list may lose through outdated costs, unrevised prices, waste, discounts or slow references.
Problem solved
Margin leaks when cost rises, supplier tariffs change, selling price stays fixed, waste increases or a reference rotates too slowly.
When to use it
Use it after new tariffs, before publishing a list, when reviewing delivery notes or when theoretical margin does not match real cash.
Decision it prepares
It prepares repricing, renegotiation, supplier change, by-the-glass adjustment, visibility changes or removal decisions.
How it connects with Winerim
The tool is an initial diagnostic. Winerim Core and Winerim Supply connect that reading with wine list, stock, purchases, sales, cost and margin so decisions are not made from a spreadsheet alone.
Next step
After the calculation, the team can review the full wine list, compare references, request a demo or upload the list for a deeper analysis.
