A retired dairy co-op executive reviews mailbox milk prices, the net amounts farmers receive after marketing deductions, using AMS data for 2017 and 2018. The analysis compares mailbox prices with adjusted federal order blend prices across 19 reporting areas.
California data is incomplete because it joined the federal order system in 2018.
Mailbox prices show the real farm-gate return after hauling and co-op deductions. This helps buyers judge regional milk supply economics.
After 136 past neutral report events, Milk (Class III) moved a median -0.1% over 5 sessions (43% higher; middle half -0.7% to +0.5%), and -0.3% over 20.
