Overstock Cost Calculator

Enough to cover your supplier lead time plus safety stock plus one review cycle. A store restocking from overseas on a 6-week lead often targets 8–12 weeks; one with a domestic 1-week supplier can run 3–4. Setting the target is the honest part of measuring overstock cost — a generous target hides excess, a tight one flags stock you genuinely need.

No, and the distinction decides the remedy. Overstock is a product that sells at a healthy rate — you simply hold more weeks of it than you need, so the fix is to pause reordering and let sales bleed it down. Dead stock barely sells at any level, so waiting doesn’t help and you need markdowns or liquidation. This calculator prices the first problem; the dead stock cost calculator prices the second.

The quiet costs are opportunity and risk: $7,200 parked in excess of one SKU is $7,200 not buying the fast mover that keeps stocking out, and every extra month on hand adds exposure to damage, obsolescence, and price erosion. There is also a Q4 trap — overstock occupying 3PL or FBA space during peak-surcharge months can double its storage component exactly when space is most expensive.

In order of margin preserved: stop reordering and let it sell through; feature it in email flows and bundles where the marketing cost is near zero; run a modest 10–15% promotion; and only then discount deeply or liquidate. Match the aggression to the carrying cost — if excess stock burns $150 a month, a slow no-discount bleed-down is fine; if it burns $1,500, buy the cash back faster.
