Milk Calculator works out the price of milk from fat and SNF in seconds, for dairy farmers, milkmen and milk collection centres. No login, no internet needed, and your rates are remembered.

FAT RATE CALCULATOR
• Milk price by fat: quantity × fat % × rate per kg of fat
• Enter litres or kg (1 litre = 1.03 kg, adjustable)
• See total amount, rate per litre and rate per kg

FAT + SNF RATE (TWO-AXIS PRICING)
• Price by fat kg and SNF kg, as used by most dairy co-operatives
• Type SNF, or enter the lactometer reading (CLR) and get SNF automatically
• One tap to set the SNF rate at ⅔ of the fat rate
• Shows fat kg, SNF kg and total solids (TS)

CLR TO SNF CONVERTER
• BIS / ISI lactometer formula: SNF = CLR/4 + 0.25 × Fat + 0.44
• Also Zeal, Richmond and other formulas — pick the one your dairy uses
• Lactometer temperature correction
• SNF to CLR in reverse

QUALITY CHECK
• Compares fat and SNF with FSSAI minimums for cow, buffalo and mixed milk
• Estimates possible added water from low SNF

RATE CHART
• Base rate per litre at standard fat/SNF (for example 3.5 / 8.5)
• Plus or minus a fixed amount for every 0.1 fat and SNF

WATER AND MILK MIXING
