About

Discounts stack with fees, shipping and returns to quietly erase your margin — while the dashboard stays green. Promo Margin Guard is a pre-sale calculator: enter price, discount, fees and shipping BEFORE the promotion to see your true profit per order, with a GO / NO-GO verdict plus a post-promo audit. Built on the break-even math most sellers never run (a 10% discount on a 40% margin needs ~33% more units to break even). Excel-based, no subscriptions, commercial license included.
