Q4 storage spike planner

For standard-size, non-dangerous goods, FBA storage is $2.40 per cubic foot from October to December, up from $0.78 the rest of the year. This planner compares sending all Q4 stock into FBA before October with keeping the rest in AWD and replenishing in chunks. It also gives you a ship-by date for each replenishment.

Q4 sales forecast

Replenishment settings

Days from shipping out of AWD or your 3PL until units are available in FBA.

Days of sales each replenishment shipment covers.

Your AWD rate per cubic foot per month, from $0.38 to $0.57 depending on region and rate type.

This defaults to today's date plus your lead time, but never earlier than October 1, so your first ship-by date is today or later.

How the math works

  • Storage only: AWD processing and transportation fees are not included.
  • Not included: the FBA storage utilization surcharge.
  • Plan 1 puts all Q4 stock in FBA by your first date and sells it down at your forecast.
  • Plan 2 holds the rest in AWD and ships to FBA in cover-window chunks, keeping your safety stock in FBA.
  • AWD storage here uses unit cubic feet. AWD stores full cases, so empty space in your cases adds to the real AWD cost.
  • Since July 31, 2026, AWD accepts only units under 18 x 14 x 8 in and under 20 lb. For larger items the tool shows Plan 1 only.
  • Oversize stock already in AWD, or in AWD shipments created before July 31, 2026, can stay and keep replenishing to FBA. This planner covers new AWD shipments.
  • Each month's forecast sells at an even daily rate.
  • The holiday premium is the October to December FBA rate minus the January to September rate on the same volume. AWD has no holiday surcharge.
