How do I calculate the yield loss from slitting a master coil?

Start with the master coil width and subtract the total slit width across all strands plus the edge trim on each side. The Slitting Yield calculator divides usable slit weight by master coil weight, and Trim Scrap Cost values the edge trim at scrap price. Typical edge trim runs 0.25 to 1 inch total, so on a 48-inch coil you can lose 1 to 2 percent of weight before any strand is even used.

What is the difference between blanking utilization and nesting yield?

Blanking Utilization measures the percentage of strip area that ends up in finished blanks versus skeleton scrap on a single-part layout. Nesting Yield extends that to multiple parts arranged together across the strip and length to minimize web and end scrap. Round or irregular blanks often stall at 65 to 80 percent utilization, so nesting two or more parts can recover several points of yield and cut scrap cost per part.

How do I account for metal surcharges when quoting coil work?

Separate the base conversion cost from the metal cost, then apply the Metal Surcharge Impact calculator to the current index. Surcharges on stainless and aluminum move monthly and can swing 10 to 30 cents a pound, so quoting a fixed all-in price exposes you to margin loss. Quote conversion plus a pass-through surcharge tied to a published index date, and use Steel Coil Cost to confirm the landed base.

How much coil do I lose per changeover on a cut-to-length line?

Coil Changeover Loss captures the threading scrap, the lead and tail crop, and any off-gauge or off-color at the head of the coil. On a cut-to-length or roll forming line this is commonly 15 to 60 feet per coil depending on line speed and leveler setup. Multiply by coil weight per foot and your run frequency, then compare against Coil Inventory Days to decide whether larger coils justify fewer changeovers.

How do I convert coil weight to lineal feet of a given gauge?

The Lineal Feet From Coil calculator divides coil weight by the weight per foot, which comes from width, gauge, and material density. Steel runs about 40.8 pounds per cubic foot per inch of thickness at standard density, so a 48-inch by 0.060-inch coil weighs roughly 9.8 pounds per foot. Pair this with Cut-To-Length Throughput to turn a coil into a piece count and a run time.

What scrap recovery should I expect on trim and drop?

Scrap Metal Value applies the current scrap index to the pounds identified by Trim Scrap Cost and your process drop. Prime bushing and clean prompt scrap recover a high fraction of the base, while coated or mixed material recovers less. On a slitting operation losing 2 percent to edge trim, the recovered scrap credit can offset a meaningful share of that loss, so track it as a line item rather than folding it into overhead.

Best calculators in this category

Coil Yield: Calculate coil yield by comparing the prime weight you ship against the master coil weight you ran, then see how far the result sits from your yield target.
Steel Coil Cost: 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.
Aluminum Extrusion Cost: Estimate aluminum extrusion cost from extruded weight, an all-in price per pound that covers metal plus conversion, the share of the order priced now, and a die and setup charge.
Slitting Yield: Calculate slitting yield by comparing the prime weight of the finished mults against the master coil weight you slit, after edge trim and crop loss.
Blanking Utilization: Estimate blanking utilization by comparing the blank area used per sheet or strip against the total sheet area, then see the gap to your material utilization target.
Coil Changeover Loss: Estimate the run time lost to coil changeovers from the number of changeovers, how many the crew completes per hour, and a threading and setup allowance.
Scrap Metal Value: Estimate the recoverable value of scrap metal from scrap weight, the scrap price per pound, the payable share after deductions, and any container or sorting premium.
Cut-To-Length Throughput: Estimate cut-to-length throughput from the sheets cut, the run time, and a realistic line efficiency, so you can compare the line against the required pace.
Gauge Variation: Check gauge variation across a coil or lot by entering the highest and lowest thickness readings and the nominal gauge target, then see the spread and how the midpoint sits versus nominal.
Coil Inventory Days: Size coil inventory from daily coil consumption, supplier lead time, and a safety stock buffer, so you can see the days of supply you are carrying.
Nesting Yield: Calculate nesting yield by comparing the net part area placed on a sheet against the full sheet area, then see the gap to your nesting target.
Roll Forming Speed: Set roll forming line speed from the required piece output, the cut length per piece, and a realistic line efficiency, so the first setup lands close.
