Flour Milling & Atta, Maida & Bran
Mills wheat
Enter your wheat quantity and extraction percentage to get the atta or maida flour, the bran by-product and the total value — whole-wheat atta runs high, refined maida lower with more bran.
Mill your wheat
Next: mill 1,000 kg at these extraction rates for 720 kg atta + 0 kg maida + 280 kg bran, then sell the streams for ~₹34,400 gross.
Extraction rate is the share of wheat recovered as flour; higher atta extraction keeps more bran in the flour. Bran/germ by-products often sell as cattle feed. Atta + maida % should not exceed 100.
Flour milling — key facts

Every grain accounted for
Milling wheat is a split decision. Grind it whole and you get atta at around 95% extraction — almost the entire grain becomes flour. Refine it for maida and the extraction drops, the flour turns white and fine, and a bigger bran stream comes off the side. Neither is simply better: whole-wheat atta keeps the fibre and nutrients, refined flour earns more per kg and throws off bran, germ and suji that sell in their own right. Knowing the split is how you price the job.
This tool turns your wheat and extraction rate into the flour yield, the bran by-product and the total value of the output in 8 currencies — so a miller can quote a customer, a trader can compare extraction scenarios, and a farmer can decide whether to sell grain or get it milled. Pair it with the Rice Milling Recovery, Dal Milling Recovery and Value Addition Profit tools to value the whole processing chain.

Frequently Asked Questions
How is flour extraction calculated?+
Flour = wheat × extraction percentage. At a 95% extraction, 100 kg of wheat gives 95 kg of flour; the rest leaves as bran, germ and milling loss. Bran (the by-product) = wheat − flour. This tool multiplies your wheat by the extraction rate, splits out the bran, and prices the output so you see the full milling return.
What is extraction percentage?+
Extraction (or extraction rate) is the share of the wheat grain that ends up as flour. Whole-wheat atta runs high — around 95% or more — because it keeps most of the grain. Refined maida is lower, often 70–80%, because more of the bran and germ are removed. The lower the extraction, the whiter the flour and the more bran by-product.
What's the difference between atta and maida?+
Atta is whole-wheat flour milled at high extraction (≈95%), keeping the bran and germ, so it's higher in fibre and nutrients. Maida is refined flour milled at lower extraction, with most bran and germ removed for a fine, white, low-fibre flour used in bakery and confectionery. The same wheat can make either, at different extraction rates.
What are the by-products worth?+
Bran, germ and suji (semolina) are valuable by-products, not waste. Bran sells as cattle feed and for high-fibre foods; suji and germ command good prices in their own right. Including by-product value is key to the true return on milling — refined flour earns less per kg of wheat unless you also sell the bran stream.
What's a typical extraction for an atta chakki?+
A small stone chakki grinding whole wheat is essentially 100% extraction minus a little loss — almost all the grain becomes atta. Roller flour mills making maida run lower extraction with more by-product streams. Enter the rate your mill actually achieves to match the yields to your machine.
Does higher extraction always mean more profit?+
Not always. Higher extraction gives more flour per kg of wheat, but lower-extraction refined flour fetches a higher price per kg and produces sellable bran. The best mix depends on your market and by-product outlets. Use the total-value output to compare scenarios and choose the extraction that pays best for you.
Will it work for other grains?+
The extraction logic — flour = grain × extraction rate, by-product = the remainder — applies to other milled grains too, though typical rates differ. For wheat it's the natural fit; for maize, millets or other cereals, just enter the extraction rate and prices that match that grain and your mill.
What units and currencies does it use?+
Enter wheat in kg, quintal or tonne, set the extraction percentage and the prices, and read the atta or maida, bran and total value. It works in 8 currencies, so millers and traders can price the output in their local currency for planning and quoting.
Are the figures exact?+
They are solid planning figures. Real yields vary with wheat quality, moisture, the mill's condition and how it's run, and prices move daily. Calibrate the extraction rate against a known batch on your mill, update prices, and use the tool to plan and quote — it steers decisions rather than promising an exact weigh-bridge result.
