Sheet Metal Stamping & Press Lines calculator
Strip Layout Yield Calculator
Find the material yield designed into one repeating strip pitch. You need net part area, parts per pitch, strip width, pitch distance and your approved yield target.
What this calculator does
- Calculate the material share retained by one repeating strip pitch against your layout target.
Formula used
- Stock area per pitch = strip width × feed pitch
- Retained area per pitch = net part area × parts per pitch
- Layout yield (%) = 100 × retained area ÷ stock area
- Layout scrap share (%) = 100 − layout yield
- Gap to target = layout yield − target yield
Inputs explained
- Net Finished Part Area: CAD flat area after all holes and trimming are removed.
- Finished Parts per Pitch: Layout drawing count released per repeated strip pitch.
- Strip Width: Specified incoming strip width on the die layout.
- Feed Pitch: Repeat distance marked on the progressive strip layout.
- Target Strip Layout Yield: Approved material yield requirement for this die layout.
How to use the result
- Best suited to progressive strip design review, layout material quote check.
- Area yield does not include threading, coil ends, rejects or other run losses. Equal total areas do not prove parts fit or carriers remain strong.
Current U.S. benchmarks
- The producer price index for steel mill products stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. Quotes priced off last quarter's material cost miss this move.
- U.S. iron and steel import customs value ran $2.2B in Aug 2026 (Census International Trade). The U.S. ran a trade deficit of $0.6B in the category that month. This dollar total mixes price, quantity, product mix, origin, and timing; it does not measure physical import volume or prove a tariff or reshoring effect.
- The U.S. has 53,790 fabricated metal products establishments employing about 1,441,471 workers (Census County Business Patterns, 2023).
Common questions
- Do I count the holes in part area? Subtract the holes and trimmed regions. Only material remaining in the finished part belongs in the retained area.
- What does parts per pitch mean? It is the number of finished parts released for each repeat of the strip layout. Use the repeat distance associated with that count, including every lane.
- Why is actual coil yield lower? Actual coil consumption can include threading, setup, coil stubs and rejected parts. This geometric ratio covers a steady repeating pitch; weigh the complete run for coil yield.
- Can I reduce the carrier to meet the target? Only after a tooling review confirms stable feeding and adequate support. Carrier material is scrap in this ratio, but removing it can cause quality and feed problems.
