Maintained markup calculator: what the season actually earned

Initial markup is a plan. Maintained markup is the result. Enter your unit cost, original ticket price, and the units sold at each markdown depth — the calculator returns maintained markup on cost, maintained margin on retail, average unit retail, markdown dollars, and margin erosion in points.

Maintained markup, in one paragraph

Maintained markup is achieved gross profit divided by cost of goods sold, after every markdown has been taken. The same dollars divided by net sales is maintained margin. The gap between initial and maintained is what your markdown cadence cost you, and it is reported in percentage points because two percentages are being compared.

Two figures do the work: average unit retail, which is what customers actually paid on average, and markdown dollars, which is the reduction per unit multiplied by the units sold at that reduction. Everything else follows from those.

Calculate maintained markup

Defaults show 1,000 units at an $18.00 cost and a $49.00 ticket, sold across four price points. Change any figure.

Maintained markup is measured against cost, maintained margin against realized retail. Both use the units you actually sold at each price, so they answer "what did this markdown cadence really earn" rather than "what did I plan to earn".

Read the third column, not the first. A 40% price cut removes 63% of the profit on that unit — which is why the units-per-price mix matters more than the headline discount.

Why the mix matters more than the depth

A season that sells 60% of units at full price and clears the rest at 50% off can hold a healthier maintained markup than one that sells 30% at full price and clears the rest at only 30% off. The depth on the ticket is a smaller lever than the share of units that clear before you reach it — which is a timing decision, not a pricing decision.

Forecast maintained margin instead of measuring it late

The planner projects the unit mix from your sell-through assumptions, so you see maintained margin, ending stock, and cash recovered before you commit to the schedule.
