Definition and method

What this calculator answers

Divide current units on hand by average weekly demand. No universal good, low or overstock band is applied.

Weeks of cover

Weeks of stock cover = units on hand ÷ average weekly sales or demand on the same basis. It estimates how long the entered stock lasts if that weekly rate continues.

Frequently asked questions

What is stock-cover in weeks?

Stock-cover-weeks = stock on hand ÷ average weekly sales. It answers "how many weeks will the stock on my shelf last at the current pace?" before the first unit runs out and the item goes out of stock.

Stock Cover (Weeks)

What cover window is a sweet spot?

Use a measurement period and refresh cadence that match the decision, data volume and volatility. Shorter windows react faster while longer windows smooth noise. MarginKoala does not impose a universal timing rule.

Stock Cover (Weeks)

What if I am a seasonal store?

Use a peak-season weekly sales figure rather than a year-round average. The same cover number means very different things in November vs July — the model is the same, the input style differs.

Stock Cover (Weeks)

Can I use this for slow movers?

Yes — combine with the dead-stock-cost calculator. Stock-cover below 4 weeks on slow movers is a restock urgency; cover above 26 weeks on the same is liquidation urgency.
