FORMULA 1 · KILO FAT
How Formula 1 prices a litre
Two numbers you set, and the milk's FAT and SNF. The app works out every rate in the chart this way.
Rate × SNF Base ÷ 100 × (FAT + ⅔ × SNF)
In the app: 36 × 8% × (FAT + ⅔ SNF)
Buffalo milk · FAT 6.0 · SNF 9.0
Rate × SNF Base ÷ 100
36 × 8 ÷ 100 = 2.88
FAT + ⅔ × SNF
6.0 + 6.0 = 12.0
2.88 × 12.0 = ₹34.56
Cow · FAT 3.5 · SNF 8.5
FAT 6 · SNF 9, Rate 37
FAT 6 · SNF 9, SNF Base 8.5
Not the same as Formula 2: Formula 2 (Fat + SNF Rate) is FAT × Fat Rate + SNF × SNF Rate, a different chart. For Formula 1, pick Kilo Fat.
Rate: The main number: ₹1 more adds ₹0.96 a litre at FAT 6 · SNF 9.
SNF Base: Usually 8. 8.5 instead of 8 adds about 6% to every rate.
Rounded: Each rate to 2 decimals; the amount is litres × rate.
