Buyer’s guide

Buyer’s guide to factory calculators

Use these tools to review supplier quotations, discuss production capacity and prepare quality checks. Start with comparable records: agree the currency, quantity, measurement units, operating period and buyer requirements before comparing results. A calculated result is not a supplier audit, an approved specification or a delivery guarantee.

All 118 available entries below explain their industry use, method, units, assumptions and practical limits. Confirm source measurements and applicable buyer policies with the supplier. Estimates support discussion; they do not certify compliance. The eight advanced tools use manual entries, not automated image or video analysis.

Costing

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

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.
Limitations for buyers
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.
Industry use
The average cost incurred to keep one minute of production capacity available, blending fixed and variable operating costs.

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