Flour Milling Recovery Calculator

Work out flour milling recovery instantly with clear inputs, formula shown and shareable results.

About Flour Milling Recovery Calculator

Extraction rate is flour as a percentage of wheat milled — 72-76% for straight-grade white flour, up to 95% for atta. Flour plus bran should account for nearly all the wheat; the shortfall is invisible loss from moisture evaporation, dust and spillage, and above about 1% it signals a problem.

Formulas

Extraction rate

Extraction % = flour x 100 / wheat milled

Balance

Total recovery % = (flour + bran) x 100 / wheat; invisible loss = 100 - total recovery

Worked example

With the default values below, Flour Milling Recovery Calculator returns Flour Extraction Rate of 74.50%. 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

Why is high extraction not always better?

Pushing extraction raises ash and bran specks in the flour, hurting colour and baking quality. Each grade has an ash ceiling that caps how far extraction can go.

What is a normal invisible loss?

0.3-0.8% in a well-run mill, mainly conditioning water evaporating during milling. Above 1.5% suggests leaks, dust escape or weighing errors.
