Why this isn’t a toy calculator
- Window + noise — promo weeks don’t silently inflate cover.
- Inbound-aware — cover today vs cover after PO lands.
- Category thresholds — consumables and seasonal stock use different healthy bands.
- Budget context — high spend on thin cover escalates the warning.
- Scenarios — if sell rate jumps 20%, or inbound slips a week.

FAQ
What is days of cover?
Units you can sell ÷ daily sell rate ≈ days until stockout if nothing changes. Also called weeks of supply when divided by 7.
Which lookback should I use?
14 days is a solid DTC default. Use 7 if the world just changed (launch, promo). Use 28–30 if volume is thin or noisy.
Should I include inbound stock?
Only if it’s confirmed and timed. Fantasy POs create fantasy cover — and real stockouts.
