BUILT FOR THE WATERFALL

Each retailer does it different. We’re prepared. Are you?

MODEL-AWARE

Each retailer’s real waterfall

Walmart’s allowance stack, Costco’s free-fill + slotting, AutoZone’s cost-plus markup, each modeled with the deductions that retailer actually takes.

PARTIAL INPUT OK

Missing COGS? Still works.

Engine fills missing COGS from a cost-ratio slider (default 40% of list, tune per retailer). You get a real answer from list + units alone, flagged where it’s estimated.

EXPORTABLE

Drop the answer into your deck

Save this program in your workspace and Margin Math becomes the substance behind your Section 8 pricing slide, same numbers, no rekeying.
