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 pricing slide, same numbers, no rekeying.
