Order Fill Rate Calculator

Work out order fill rate instantly with clear inputs, formula shown and shareable results.

About Order Fill Rate Calculator

Fill rate can be measured per line or per order, and the two differ sharply. A 95% line fill rate on a ten-line average order produces only about 60% perfect orders, because one short line spoils the whole order — which is what the customer actually experiences.

Formulas

Line fill rate

Line fill % = Lines shipped complete / Lines ordered x 100

Order fill rate

Order fill % = Orders shipped complete / Orders received x 100

  • 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.
  • This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.

Frequently Asked Questions

Which measure should I report?

Report both. Line fill drives replenishment decisions; order fill reflects customer experience and is the one to put in a service level agreement.

Does a partial shipment count as filled?

Not for order fill rate. For line fill, a line is filled only if the full requested quantity shipped within the promised window.
