Who is the cheatsheet for?
Apparel merchandise planners, buyers, allocators, merchandisers, analysts, supply chain operators, and executives who want one durable reference for the retail math their work depends on. Also useful for finance teams, consultants, and product leaders who evaluate apparel planning decisions.
How is this different from the live calculators on the site?
The live calculators at /resources/formulas are interactive — plug in your numbers and see the result against the channel benchmark. The cheatsheet is a printable desk reference — one page, one glance, no internet required. Both are free; the calculators are ungated, the cheatsheet is gated for work-email delivery.
Does the cheatsheet include benchmark ranges?
The cheatsheet is formula-first. For the full channel-specific benchmark ranges (DTC / Wholesale / Luxury / Mid-market, bad / good / great bands), download the companion Apparel Retail Math Benchmark Pack — also available on the formulas hub.
Running the math is one thing. Running the system is another.
