About Planogram Facings Calculator

Facings must hold enough stock to cover demand between replenishment visits plus a safety allowance, otherwise the shelf empties before the next fill. Increasing replenishment frequency is the alternative to giving a line more space — which is why space and labour trade off directly.

Formulas

Demand between visits

Demand = Weekly sales / 7 x Days between visits x (1 + Safety %)

Facings

Facings = ceiling(Demand between visits / Units per facing depth)

Worked example

With the default values below, Planogram Facings Calculator returns Facings required of 6. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What happens if facings are too few?

The line goes out of stock on shelf even though stock exists in the back room, which is the largest single source of lost retail sales.

Should fast lines always get more facings?

Up to the point where the shelf covers the replenishment cycle. Beyond that, extra facings only buy visibility, not availability.
