Frequently asked
What is in the workbook?
A single .xlsx file with 11 tabs: a README, a Registry tab with every formula and its equation + example + primary role + category, 8 role tabs (Designer, Merchandiser, Planner, Buyer, Allocator, Supply Chain, Analytics, Executive), and a Benchmarks tab with illustrative bad / good / great ranges for DTC, Wholesale, Luxury, and Mid-market.
Can I edit and customize it?
Yes. Every cell is editable. Plug in your own numbers, change the formulas to match your brand's conventions, or copy the format into your existing planning workbook. It is a working file, not a locked template.
How is this different from the cheatsheet PDF?
The cheatsheet is a 3-page printable desk reference. The workbook is a working Excel file — searchable, sortable, filterable, and editable. Power users who want to embed the formulas in their own planning templates should start with the workbook; glance-readers should start with the cheatsheet.
Does the workbook include live calculators like the website?
The workbook has equations and worked examples for every formula, but the live interactive calculators live on retailnorthstar.ai/resources/formulas — each with interpretation text, and illustrative channel ranges on 16 of them. Use the workbook for reference and your own spreadsheet builds; use the live calculators for quick in-browser modeling.
A workbook is a start. A planning system is a business.
RetailNorthstar runs these 40 formulas live across plan, on-hand, and open orders — so your team is acting on numbers, not rebuilding them in Excel each week.
