How do you calculate steel coil cost?

Multiply coil weight by base price by the share charged to the job, then add freight and processing. At 100 cwt, $45/cwt, 80 percent share, plus a $250 adder, material is $3,600 and total cost is $3,850.

What is cwt in steel pricing?

Cwt is hundredweight, or 100 pounds. A price of $45 per cwt means $0.45 per pound, so a 10,000 lb coil is 100 cwt. Steel and aluminum are routinely quoted this way in North America.

Why charge only a share of the coil to a job?

One coil often supplies several orders, so charging the full coil to one job overstates its cost. The 80 percent share in the default case allocates $3,600 of material, leaving the remaining 20 percent for other jobs.

What is the cost per cwt charged?

It is total cost divided by the cwt actually charged. In the default case, $3,850 over the 80 cwt charged is $38.50 per cwt, which is below base price because the fixed adder spreads across charged weight differently than the base rate.

Should freight be a flat adder or per cwt?

This calculator uses a flat adder, which suits per-coil or per-shipment freight. If your freight scales with weight, fold it into the base price instead so heavier jobs carry proportional freight.

How do surcharges affect coil cost?

Alloy, scrap, and energy surcharges ride on top of base price and move monthly. For accurate quotes, either add them into the base price per cwt or treat them as part of the freight and processing adder.

Metals, Steel, Aluminum & Coil Processing calculator

Steel Coil Cost Calculator

Steel Coil Cost converts hundredweight pricing, partial-coil usage, and freight into the true delivered material cost charged to a job. Steel is quoted in dollars per cwt (hundredweight), and a single coil rarely maps to one order, so estimators must charge only the share a job consumes and then layer in freight and processing. This calculator multiplies coil weight by base price by the share charged, then adds the freight-and-processing adder to give a total and a cost-per-cwt figure. Estimators, buyers, and job-cost controllers use it to quote accurately, validate vendor invoices, and avoid eroding margin on under-recovered material.

What this calculator does

Estimate the landed cost of a steel coil from coil weight, base price per hundredweight, the share of the coil charged to the job, and a fixed freight and processing adder.
Use it when a buyer or estimator needs a defensible steel coil cost before quoting a slitting, blanking, or cut-to-length order.
It computes the material cost for the share of a coil charged to a job plus a freight and processing adder, and the resulting cost per cwt charged.

Formula used

Material cost = coil weight × steel base price × share of coil charged to job
Total steel coil cost = material cost + freight and processing adder

Inputs explained

Coil weight:
Steel base price:
Share of coil charged to job:
Freight and processing adder:

How to use the result

Use it when quoting a job, allocating a coil across multiple orders, or checking a steel invoice against expected delivered cost.
It uses a single base price and a flat adder; volatile spot pricing, surcharges, and per-cwt freight that scales with weight are not modeled, so update the base price each quote.

Current U.S. benchmarks

The producer price index for steel mill products stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The producer price index for aluminum mill shapes stands at 404.859 (BLS, May 2026), up 36.8% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The producer price index for copper and brass mill shapes stands at 559.593 (BLS, May 2026), up 76.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,484 per tonne (IMF via FRED, May 2026).
