A variance identifies a reconciliation gap; it does not identify the cause. Check portions, waste, transfers, invoice timing and count accuracy.

Next action

Trace the variance through portions, waste, transfers, invoices and count accuracy.

Check against: Recipe or theoretical usage report and verified stock reconciliation.

Show the calculation
  • Usage variance = actual usage − theoretical usage.
  • Variance rate = usage variance ÷ theoretical usage × 100.
  • Positive means actual usage was higher than theoretical.

A scenario is a decision aid. No saving or outcome has been verified.
