A service center owner told us he priced his slitting at $0.02 per pound because "that is what everyone else charges." We asked if he had calculated his actual cost per pound to slit. He had not. When we worked through the math together, his cost was $0.024 per pound. He had been losing money on every pound he slit for three years.
Building a Cost Model
Processing cost has four components: labor, machine time, consumables, and overhead. Calculate each one per unit of output (per pound, per cut, per piece) depending on the service.
For slitting, labor is the operator and helper time to set up the slitter, run the coil, band and tag the mults, and clean up. Time the complete cycle on a representative job. If a 40,000-pound coil takes 90 minutes including setup and teardown, and your two-person crew costs $60 per hour fully loaded, your labor cost is $0.0225 per pound.
Machine cost includes depreciation (or lease payments), maintenance, and the capital cost of the money tied up in the equipment. A slitting line that cost $1.5 million, runs 2,000 hours per year, and processes 80 million pounds per year has a machine cost of roughly $0.005 per pound including maintenance reserves.
Consumables (knives, spacers, arbor maintenance, packaging materials) add $0.002 to $0.004 per pound depending on the material and how often you regrind. Overhead allocation (share of rent, utilities, insurance, management) adds another $0.005 to $0.008 per pound.
Total cost in this example: $0.034 to $0.039 per pound. If you are charging $0.02, you are subsidizing your processing customers with your distribution margin.
Pricing by Complexity, Not Just Weight
A straight slit of a 48-inch coil into four 12-inch mults is fundamentally different from slitting a 60-inch coil into nine mults of varying widths with tight tolerances. The setup time is different, the run speed is different, the scrap rate is different, and the risk of a quality problem is different. Pricing both at the same per-pound rate makes no sense.
Build pricing tiers based on complexity. Simple jobs (2 to 4 mults, standard widths, loose tolerances) get base pricing. Medium complexity (5 to 8 mults, mixed widths, moderate tolerances) gets a 20% to 30% premium. High complexity (9+ mults, narrow widths under 2 inches, tight tolerances, critical surface quality) gets a 50% to 75% premium.
For cut-to-length operations, price by the cut, not by the pound. A shear cut takes roughly the same time whether the sheet weighs 200 pounds or 2,000 pounds. Charge per cut with a minimum charge per order. This ensures small-quantity orders cover your setup and handling costs.
The Setup Charge Debate
Many service centers resist charging setup fees because they fear losing business. But setup is real cost. A slitter setup takes 30 to 60 minutes of skilled labor. That is $30 to $60 in direct cost before a single pound is processed. On a 5,000-pound order, absorbing a $45 setup cost adds $0.009 per pound to your real cost. On a 50,000-pound order, it is less than $0.001 per pound.
The solution is a minimum order charge that covers setup on small orders and gets absorbed into the per-pound rate on large orders. Set it at $75 to $150 depending on the process. Most customers understand that small orders cost more to process. The ones who push back hardest on setup charges are usually the same customers whose small, complex orders are losing you money.
Review Pricing Quarterly
Your costs change. Labor rates go up. Electricity rates fluctuate. Consumable prices follow raw material markets. If you set processing prices two years ago and have not reviewed them, you are almost certainly undercharging today. Build a quarterly pricing review into your management calendar. Compare your actual cost per pound or per cut against your pricing and adjust. Your customers will not like price increases, but they will accept them if you can explain the cost drivers. The ones who leave over a $0.005 per pound increase were probably not profitable accounts anyway.
