How the calculation works
How is theoretical SMP price calculated?
The formula credits the fat fraction to butter first, then allocates the remaining milk value to the protein fraction. SMP yield is approximately protein% / 0.335 kg per 100 kg milk. The residual milk value divided by SMP yield gives the theoretical price.
Why does the butter price affect theoretical SMP?
Fat and protein share the same raw milk. When butter prices rise, the fat credit grows, leaving less revenue to attribute to SMP, so theoretical SMP falls even if the milk price stays the same.
What fat and protein yields does this calculator use?
Butter yield: fat% / 0.82 (82% butterfat content). SMP yield: protein% / 0.335 (33.5% protein solids recovery). These are standard EU industry benchmarks.
