Frequently asked
Which formulas have illustrative ranges?
IMU, MMU, sell-through rate, GMROI, weeks of supply, forward weeks of supply, inventory turns, fill rate, markdown %, gross margin %, allowances %, stock-to-sales ratio, return rate, inventory accuracy, comp store sales, and PO coverage. For each, the pack shows illustrative bad / good / great bands across DTC, Wholesale, Luxury, and Mid-market channels.
Where do the ranges come from?
They are illustrative reference points, not a published benchmark — editorial operator judgment from hands-on apparel planning work, not a measured dataset or survey. Set targets from your own history: your category, your customer, and your brand equity all move the right band up or down.
Why do the ranges differ by channel?
Apparel economics are not uniform. DTC margin structure absorbs return + shipping cost in IMU; wholesale margin is capped by retail-partner demands. Luxury supports higher IMU because markdowns damage equity; mid-market lives in the middle. One range applied across every channel misreads the business, because the cost structures behind each channel differ.
How is this different from industry benchmark reports?
A benchmark report measures a defined sample. This pack does not — its ranges are illustrative reference points from operator judgment, so read them as a starting point, not a measured norm. What it offers is specificity: every range is attached to a formula you use in planning — IMU, WOS, fill rate — and split by channel.

RetailNorthstar tracks these metrics live against the plan you set from your own history — so the gap between plan and actual is always visible.
