Cutting Wastage Calculator

A fabric cutting wastage percentage calculator measuring marker efficiency and lost meters. Use the free Cutting Wastage Calculator below — enter your values and get instant results, right in your browser. Wasted fabric (m) = fabric issued − (pieces cut × theoretical m per piece). Wastage % = wasted ÷ issued × 100. Marker efficiency = 100 − wastage %. Example: 100 m issued, 40 pieces × 2.3 m = 92 m used → 8 m wasted = 8% wastage, 92% efficiency.

How to use the Cutting Wastage Calculator

Every centimeter between pattern pieces on the cutting marker is money in the bin — and most factories never measure it. This fabric cutting wastage percentage calculator compares the fabric issued against the theoretical fabric in the good pieces cut, revealing the wasted meters, the wastage percentage, and the marker efficiency. It is how cutting masters prove (or improve) their nesting.

  1. Enter the meters of fabric issued to the cutting table.
  2. Enter the number of good pieces actually cut (exclude miscuts).
  3. Enter the theoretical fabric consumption per piece from your costing.
  4. Click Calculate to see wasted meters, wastage %, and marker efficiency.
  5. If wastage exceeds 15–20%, ask the CAD team to re-nest the marker before the next lay.

Formula

Wasted fabric (m) = fabric issued − (pieces cut × theoretical m per piece). Wastage % = wasted ÷ issued × 100. Marker efficiency = 100 − wastage %. Example: 100 m issued, 40 pieces × 2.3 m = 92 m used → 8 m wasted = 8% wastage, 92% efficiency.

Worked example

A cutting order issues 250 m for 100 kurtas at 2.3 m theoretical each: used = 230 m, wasted = 20 m, wastage = 8%, efficiency 92% — excellent. If only 90 good pieces come out, wasted = 250 − 207 = 43 m = 17.2% wastage — the marker or the cutting needs attention before the next 1,000-piece order.

Frequently asked questions

10–15% (85–90% marker efficiency) is normal and already priced into costing. Below 8% is excellent CAD work; above 20% signals a bad marker, wide fabric, or sloppy cutting that needs fixing.

Tighter CAD marker nesting, cutting mixed sizes in one lay, matching fabric width to the marker, and training cutters to follow the lines. Even a 2% efficiency gain saves lakhs on large orders.

End bits and small cuttings are sold to recyclers by weight for shoddy/mattress filling, larger remnants become wiping rags or small accessories. Good waste segregation recovers a small but real value per order.
