What it measures
The 12-month change in the Producer Price Index for construction materials, a broad measure of what suppliers charge for lumber, steel, concrete, wiring and other building inputs.
Why it matters to a small business
Contractors who bid a job months before buying materials carry this risk directly. A fast-rising index squeezes margins on fixed-price work.
