Ghee Calculator

Calculate how much ghee your cow or buffalo milk will yield, or how many litres of milk are required for 1 kg of pure ghee.

Cow milk is usually 3.5–4.5% FAT; Buffalo milk is typically 6.5–8.5% FAT.

Wondering how much pure desi ghee your milk will produce, or whether making ghee is more profitable than selling raw milk? Enter your milk volume, FAT% and preparation method (cream/malai or desi bilona) to get exact ghee yield in kilograms and millilitres, along with the litres required per kg of ghee.

About the Ghee Calculator

Illustration: Ghee Calculator

Ghee is almost pure clarified milk fat (FSSAI regulations mandate a minimum of 99.5% milk fat with less than 0.5% moisture). The quantity of ghee you get depends on two factors: the FAT percentage of your raw milk, and the fat recovery efficiency of your preparation method.

How much milk is needed for 1 kg of ghee?

  • Cow milk (4.0% FAT): Needs about 27 to 28 litres with the cream/malai method, and about 30 to 31 litres with the traditional desi bilona curd churning method.
  • Buffalo milk (7.0% FAT): Needs only about 15.5 to 16 litres with the cream/malai method, and about 17 to 18 litres with the bilona method.
  • Rich buffalo milk (8.0% FAT): Needs about 13.5 to 14 litres.

Fat recovery by method

  • Cream / Malai boiling (Direct Cream Method): Boiling collected milk malai directly typically recovers 85% to 90% of milk fat (average 88%).
  • Desi Bilona Method (Curd Churning): Fermenting whole milk into dahi and churning with a wooden bilona/madhani recovers 78% to 82% of milk fat (average 80%). Some fat remains in the buttermilk (chaas), which is consumed or sold separately.
  • Cream Separator + Butter Making: Commercial dairy method recovering 90% to 94% of fat.

How to use the Ghee Calculator

  1. 1 Enter the litres of milk you plan to use.
  2. 2 Enter the milk FAT% (check your collection slip or use 4.0% for cow, 7.0% for buffalo).
  3. 3 Choose or adjust the fat recovery % for your preparation method.
  4. 4 Enter your selling price per kg of ghee to compare ghee earnings against milk sales.
  5. 5 Press Calculate to see ghee yield in kg and ml, litres needed per kg, and total earnings.

The formula we use

1 Litre of milk ≈ 1.03 kg
Milk Weight (kg) = Litres × 1.03
Total Fat in Milk (kg) = Milk Weight (kg) × (FAT% ÷ 100)
Ghee (kg) = Total Fat (kg) × (Fat Recovery% ÷ 100) ÷ 0.995
Litres of Milk for 1 kg Ghee = 0.995 ÷ (1.03 × FAT% × Recovery%)

Density of warm liquid ghee is approximately 0.905 g/ml, so 1 kg of ghee occupies roughly 1,105 ml (1.1 litres) in volume.

Worked example

You have 20 litres of buffalo milk testing 7.0% FAT and you make ghee from fresh cream (88% recovery):

  1. Milk weight = 20 × 1.03 = 20.60 kg.
  2. Fat in milk = 20.60 × 7% = 1.442 kg fat.
  3. Ghee recovered = 1.442 × 88% ÷ 0.995 = 1.28 kg (about 1,410 ml).
  4. Ghee per litre = 1,280 g ÷ 20 L = 63.8 grams/litre.
  5. Milk required for 1 kg of ghee = 0.995 ÷ (1.03 × 0.07 × 0.88) = 15.7 litres.
  6. At ₹750/kg, 1.28 kg yields ₹960, which equals ₹48.00 per litre return on raw milk.

Things to keep in mind

  • Don't burn the ghee residue (kasar/mawa): Overheating darkens the ghee, destroys vitamins A and E, and burns milk solids, lowering overall yield. Stop cooking when solids turn light golden brown.
  • Strain while hot: Use clean muslin cloth or double stainless mesh. Squeeze the residue gently to extract trapped butterfat.
  • Byproduct value: In the bilona method, nutritious buttermilk (chaas) is retained, adding value that offsets the slightly lower fat recovery.

Frequently asked questions

Why does buffalo milk yield so much more ghee than cow milk?

Buffalo milk contains much higher butterfat (typically 6.5% to 8.5%) compared to cow milk (3.5% to 4.5%). Because ghee is pure milk fat, 1 litre of buffalo milk yields roughly 60–75 g of ghee, whereas 1 litre of cow milk yields about 35–40 g.

How much ghee is obtained from 1 kg of butter (makkhan)?

Indian country butter contains roughly 80% to 82% milk fat and 16% to 18% moisture. Clarifying 1 kg of butter yields approximately 780 to 820 grams of pure ghee.

Why do traditional bilona ghee makers require more milk?

In traditional whole-milk curd churning (A2 bilona), some microscopic fat globules remain emulsified in the chaas (buttermilk), giving a recovery of 78–82% compared to 88–92% in mechanical cream separation. However, bilona ghee commands a higher market premium.

How much volume does 1 kg of ghee have?

Because oil and butterfat are lighter than water (density ~0.905 g/ml), 1 kg of melted ghee equals approximately 1.105 litres (1,105 ml). A 1-litre jar holds about 905 grams of ghee.
