Milk Payment Calculator (fat + SNF rate)
Check what the dairy should pay for milk from its fat and SNF. Enter litres, fat %, SNF % and the dairy’s rates.
Quick answer
50 L, 4.5% fat, 8.5% SNF: ₹3,388.7.
How it is calculated
- Milk weight = litres × 1.03 (milk is slightly heavier than water).
- Fat kg = weight × fat ÷ 100; SNF kg = weight × SNF ÷ 100.
- Payment = fat kg × fat rate + SNF kg × SNF rate.
Worked example
50 litres of milk at 4.5% fat and 8.5% SNF has 2.318 kg fat and 4.378 kg SNF. At ₹650/kg fat and ₹430/kg SNF the payment is ₹3,388.7, i.e. ₹67.77 a litre.
| Milk | 50 L |
| Fat | 4.5 % |
| SNF | 8.5 % |
| Fat rate | 650 ₹/kg |
| SNF rate | 430 ₹/kg |
| Payment | ₹3,388.7 |
| Per litre | ₹67.77 |
| Fat kg | 2.318 kg |
| SNF kg | 4.378 kg |
Formula
kg = Lt×1.03 amt = kg×Ft/100×Fp+kg×Sn/100×Sp Payment = amt Per litre = amt/Lt Fat kg = kg×Ft/100 SNF kg = kg×Sn/100
Good to know
- Rates are examples; fill in your dairy’s rate chart.
- Many dairies give a per-litre rate from a fat-SNF table; you can check it with this.
