Where milk prices stand

Whole milk is within 5% of its BLS record high. A gallon of whole, fortified milk averaged $4.11 in September 2026, −0.6% from a year earlier and −2.9% from the prior month — leaving it 4.9% below the June 2026 record.

What drives milk prices

Farm milk supply depends on herd size, output per cow, feed and other production conditions. The retail carton price also includes processing, transport and store costs. Because milk is produced continuously and spoils fast, there is little room to store it, so prices shift as supply and demand move through the year. Federal milk marketing orders and dairy programs also shape what farmers are paid, but changes at the farm do not pass immediately or uniformly to the retail carton. The BLS observation measures the retail result without isolating these causes.
