Overstock Cost Calculator
What excess stock costs while it waits.
Cost of the overstock
$8,550
on $7,200 of excess stock
Clearing early sacrifices margin but stops the carrying cost and frees the capital. Waiting rarely improves the outcome for seasonal or trend-led goods.
How the Overstock Cost Calculator works
Overstock is a slow loss rather than a sudden one, which is why it goes unnoticed. Every month it sits, it consumes storage, ties up capital that could be buying something that sells, and moves closer to the markdown that eventually clears it.

Frequently asked questions
What does overstock cost?
Carrying cost for as long as it sits — typically 20-30% of value annually — plus the opportunity cost of capital, plus the eventual markdown. Excess stock held for a year and then cleared at 40% off has often lost more than half its value.
When should I clear excess stock rather than wait?
When the expected recovery from waiting is less than the carrying cost of waiting plus what the freed cash could earn. For anything seasonal or trend-driven, clearing early nearly always beats holding for a recovery that does not come.
How do I avoid overstocking?
Order smaller quantities more frequently, resist bulk discounts that exceed your realistic sell-through, and review slow movers monthly rather than annually. Most overstock is created at the point of ordering, not discovered later.
Is overstock worse than stocking out?
It depends on the product. For perishable, seasonal or fast-moving categories, overstock is usually worse because the loss is certain. For durable goods with steady demand a stockout is worse, because the stock would have sold eventually.
