The Cost Pressure Index: One Number for the Input-Cost Squeeze on US Manufacturers

Materials, energy, and labor all push on a manufacturer's margin at once, and no single price series captures the combined squeeze. The cost pressure index does, and here is exactly how, inputs and all.

A manufacturer's margin is squeezed from several directions at once, and watching any single price series misses the combined effect. Steel might be falling while energy climbs and wages drift up; the net pressure on cost is what matters, and no one government number reports it. The cost pressure index exists to fill that gap: it compresses the major input-cost categories, materials, energy, and labor, into a single index of how hard input costs are pushing on manufacturers right now. The value in one number is seeing the whole squeeze at a glance; the value in the methodology is being able to argue with it.

The inputs, named

The index is built from the same live series published across this site, so every component is inspectable rather than hidden in a black box. Materials pressure draws on the producer price indices for metals, resins, and other inputs, steel currently reads 361.44 index (1982=100) (Jun 2026), up about 16.9% from a year ago. Energy pressure draws on industrial electricity and natural gas, electricity at 8.7¢/kWh (May 2026), up about 5.1% from a year ago. Labor pressure draws on the manufacturing wage and unit-labor-cost series, wages at $30.35/hour (Jul 2026), up about 4.2% from a year ago. Combining them into one index is a choice about weighting, and stating that choice openly is what separates an honest index from a marketing number.

Why a composite beats a single series

The point of a composite is to capture offsetting and reinforcing moves that a single series cannot. When steel falls but energy and wages rise, a steel-only view says pressure is easing while the manufacturer's actual cost base is climbing. The index nets those against each other so the direction it reports matches the direction margins are actually feeling. That is also its honest limitation: a composite hides which component is driving the move, so the index is a headline, and the underlying series linked from it are the diagnosis. Read the index for direction, then drill into the components for cause.

Steel down, energy up, wages up: a single price series will tell you the wrong story about your margin. The point of an index is to net the squeeze into one honest direction.

Methodology you can argue with

An index is only trustworthy if its recipe is public, because the weighting is a judgment call and reasonable people can weight materials, energy, and labor differently depending on their process. A foundry feels energy far more than an assembly shop; a job shop feels labor most. So the index is published with its inputs and construction stated, not as a proprietary score to be taken on faith. If you disagree with the weighting, you can see exactly what to adjust, and that is the whole point: a number you can argue with is a number you can trust, which is the opposite of a black-box figure handed down without its recipe.

One component, six years of it

The 36-year record shows steel making a full round trip, which is why point-in-time comparisons mislead so badly here. Its high came at the close of 2021 around 449.71, gave way over the following years to 266.51 by the end of 2024, and has climbed since to 361.44. That leaves it 20% below the peak and well off the floor, so whether today looks high or low depends entirely on which year you anchored to.
