EBITDA Impact of Markdown Formula
How apparel executives calculate the after-tax EBITDA impact of markdowns — the board-level framing for why planning discipline is a P&L decision.
What EBITDA Markdown Impact measures
EBITDA markdown impact is the after-tax drop in operating earnings caused by incremental markdowns beyond plan. It is the framing that translates merchandising performance into a language CFOs and board members act on.
EBITDA Hit = Incremental Markdown $ × (1 − Tax Shield)Worked apparel example
A brand took $200K of markdowns beyond plan. Tax shield on the deductible expense is 25%.
EBITDA Hit = $200K × (1 − 0.25) = $150K
That $150K is net cash the business will not see — a direct reduction in operating earnings. For a $50M-revenue brand targeting 12% EBITDA margin ($6M), a $150K miss is 2.5% of EBITDA. Repeated two seasons running, it becomes a growth-rate conversation with the board.
Net EBITDA impact: $150,000. Board-level framing for why planning discipline and markdown control are P&L decisions, not merchandising opinions.
Why it matters at the board level
Merchandising teams discuss markdowns in merchandising terms — percent of sales, sell-through, markdown cadence. Board conversations happen in EBITDA. Translating markdown decisions into EBITDA dollars changes which decisions get escalated, and which get absorbed.
Failure modes we see
Markdown discussed only as a merchandising metric. A brand running a 22% markdown rate vs 15% planned has a "merchandising problem." Expressed in EBITDA dollars, the same overrun is $300K of missed operating earnings per season — a board-level conversation that never happens because the framing stayed merchandising-internal.
