How the math works
Inventory isn't an asset until it sells. Any stock beyond the months you actually need is cash sitting frozen on a shelf — here's how the kit sizes exactly how much.
The inputs (one overstock SKU)
One overstock SKU has $4,000 of cash frozen — 160 units past what you'll sell before it matters. The kit flags every dead and slow SKU, sizes the excess, and totals the carrying cost you're paying to store it.
Estimates from your inputs; carrying cost commonly runs 20–30%/yr. A liquidation-sizing guide, not a substitute for your accountant.
