How each calculator works

Every tool in the hub follows the same shape: you enter values from your own factory, buyer or laboratory records, the tool applies one stated method, and it shows the result with the substitution behind it. Nothing is fetched or assumed on your behalf — the quality of the answer is the quality of the numbers you enter.

Below, each of the 118 available tools is listed with the same four notes shown on its own page: Purpose, Units, Working assumption and Practical limit. Read the practical limit first: many results are planning estimates or buyer-policy decisions rather than certified values.

Costing

  • Method: CM = SMV × cost per minute ÷ (efficiency ÷ 100), then × (1 + overhead%) × (1 + profit%). CM is not Cost per Minute.

    Purpose
    The cost to convert cut pieces into a finished garment, blending standard time, cost per minute and the line's realised efficiency.
    Units
    Inputs use min, currency / min, %; result uses per garment.
    Working assumption
    Do not confuse CM with Cost per Minute. Use CM for garment-level costing and quotations; use CPM for shop-floor operating cost per capacity minute.
    Practical limit
    Use as a planning aid and verify the entered basis against the authorized factory, buyer or finance method.
  • Cost per Minute

    Calculator

    Method: Cost per minute = total operating cost ÷ total available production minutes.

    Purpose
    The average cost incurred to keep one minute of production capacity available, blending fixed and variable operating costs.
    Units
    Inputs use min; result uses per minute.
    Working assumption
    Use consistently against a defined cost boundary. Comparing cost per minute across sites is only valid when the included cost categories match.
    Practical limit
    Use as a planning aid and verify the entered basis against the authorized factory, buyer or finance method.

    Inputs use min, %; result uses min.
    Working assumption
    Use validated SMVs for line balancing, capacity and CM. A single observed cycle is a starting point — verify with multiple readings before locking a standard.

  • Method: First-pass yield (%) = first-pass units ÷ inspected units × 100.

    Purpose
    The share of units that pass end-of-line inspection the first time, without rework.
    Units

    Units
    Inputs use min, units; result uses min / unit.
    Working assumption

    Practical limit
    Use as a planning aid and verify the entered basis against the authorized factory, buyer or finance method.

Washing & Denim

  • Method: CIE76 ΔE = √(ΔL² + Δa² + Δb²); weighted mode uses user-entered coordinate weights.

Cutting Room

  • Method: Marker efficiency (%) = total pattern area ÷ marker area × 100.

    Purpose
    How much of the marker area is used by real pattern pieces vs waste between them.
    Units
    Inputs use cm²; result uses %.
    Working assumption
    Track marker efficiency by fabric width, size mix and style. Comparing across different size-mix ratios is misleading.
    Practical limit
    Use as a planning aid and verify the entered basis against the authorized factory, buyer or finance method.

    Purpose
    The largest number of plies that produces whole garments per size across a four-size order mix.
    Units
    Inputs use garments; result uses plies (max).
    Working assumption
    Combine with lay-height limits and marker length. The GCD is a mathematical upper bound; the practical plies count depends on cutting-room constraints.
    Practical limit
    Use as a planning aid and verify the entered basis against the authorized factory, buyer or finance method.

Quality

  • Advanced AQL Inspection

    Inspection workspace
    Purpose
    Apply buyer-authorized sample size and acceptance/rejection counts to recorded inspection findings.
    Units

    Working assumption
    The sample size, inspection level, severity and Ac/Re values come from the current licensed standard or buyer manual.
    Practical limit
    No licensed sampling table is embedded. This workspace calculates decisions from buyer-entered policy values and does not certify compliance.
  • Method: DHU = defects ÷ units inspected × 100.

    Purpose
    The intensity of defects normalised to a common base of 100 inspected units.
    Units
    Inputs use a consistent stated basis; result uses per 100 units.
    Working assumption
    Trend DHU by line and defect category, not as a single number. A DHU snapshot without a stratification by defect code obscures the actual root causes.

    Units
    Inputs use a consistent stated basis; result uses defects per million opportunities.
    Working assumption
    Fix the opportunity definition before tracking DPMO over time. A shifting opportunity count invalidates trend comparisons.
    Practical limit
    Use as a planning aid and verify the entered basis against the authorized factory, buyer or finance method.
  • Sigma Level

    Calculator

    Method: Sigma (short-term) = 0.8406 + √(29.37 − 2.221 × ln(DPMO)). Long-term Zlt = Zst − 1.5.

    The process capability expressed on the sigma scale, derived from DPMO via the widely-published Motorola approximation.
    Units
    Inputs use a consistent stated basis; result uses σ (short-term).
    Working assumption
    Sigma level is only meaningful with a stable, defined opportunity count. Do not compare sigma levels across processes with different opportunity definitions.
    Practical limit

AI (Advanced)

  • Method: ΔE*ab (CIE 1976) = √(ΔL*² + Δa*² + Δb*²) per roll; a roll joins the approved band when ΔE*ab ≤ the accepted tolerance, otherwise it is banded separately.

    Purpose

    Units
    Inputs explicitly use ΔE. Keep fields without a displayed unit on one consistent, documented basis.
    Working assumption
    ΔL*, Δa* and Δb* come from an instrument report measured against the approved standard under one agreed illuminant and observer.

    Units
    Inputs explicitly use cm. Keep fields without a displayed unit on one consistent, documented basis.
    Working assumption
    Measured values, spec values and tolerances all use the same unit and the same measuring method as the approved size set.

    Inputs explicitly use g, cm², specimens. Keep fields without a displayed unit on one consistent, documented basis.
    Working assumption
    Specimens are conditioned and cut with a calibrated round cutter or a measured template, and the balance is calibrated.
    Practical limit
    No image or construction prediction is used: the result is only as accurate as the weighed specimen and its measured area.
  • Method: Bath volume (L) = dry load (kg) × liquor ratio (L/kg); chemical charge (kg) = bath volume × dose (g/L) ÷ 1,000; chemical cost per garment = charge × price ÷ garments in the load.

    Purpose
    Converts a wash load and liquor ratio into bath volume, chemical charge and cost per garment. It computes an entered recipe; it does not invent or rank recipes.
    Units
    Inputs explicitly use kg, L/kg, g/L, currency / kg, pcs. Keep fields without a displayed unit on one consistent, documented basis.
    Working assumption
    Liquor ratio, dose and load are taken from the approved wash recipe card for this process step.
    Practical limit
    Dosing arithmetic only: it does not predict appearance, shade, hand feel or strength loss, and it does not suggest or optimise a recipe.
  • Method: Thread per garment (m) = Σ(seam length cm × stitch-type thread factor) ÷ 100 × (1 + wastage% ÷ 100).

    Purpose
    Sewing thread length per garment from seam lengths and the stitch-type thread factor you enter, plus a wastage allowance.
    Units
    Inputs explicitly use %, cm. Keep fields without a displayed unit on one consistent, documented basis.
    Working assumption
    The thread factor for each row comes from the stitch type and machine setting in use (for example a lockstitch 301 seam uses far less thread per cm than a 5-thread overlock 516).
    Practical limit
    Planning estimate: actual consumption varies with SPI, fabric thickness, tension, thread type and operator trimming habit. Confirm factors against your own consumption records.
  • Method: Basic time (s) = Σ(observed element time × rating ÷ 100); SMV (min) = basic time × (1 + allowance% ÷ 100) ÷ 60.

    Purpose
    Builds a standard minute value from observed element times, performance rating and an allowance. Times are entered from your own stopwatch or video review.
    Units
    Inputs explicitly use %, s. Keep fields without a displayed unit on one consistent, documented basis.
    Working assumption
    Each row is one work element of a single complete cycle, rated against the agreed normal-performance scale.
    Practical limit
    No video is analysed automatically: element times come from your own observation or video playback.
  • Method: Marker area (m²) = marker length × usable width; marker efficiency % = total pattern area ÷ marker area × 100; fabric per garment (m) = marker length ÷ garments in the marker.

    Purpose
    Marker efficiency, wastage and fabric per garment from the marker plan you enter. It evaluates a marker; it does not nest patterns.
    Units
    Inputs explicitly use m², m, pcs. Keep fields without a displayed unit on one consistent, documented basis.
    Working assumption
    Usable width excludes selvedge and any width restriction applied in the cutting room.
    Practical limit
    Evaluates the marker you describe: no nesting, no alternative-marker search and no pattern file is read.
