Will Your Team Finish on Time?

Estimate the people and hours needed to get your packages ready to ship.

Blank stays blank. No rate or industry average is filled in for you.

Your Workload And Your Team

Four figures. Anything you leave blank stays unknown — it is never treated as zero.

Outgoing packages, not items.

Everyone getting packages ready to ship in this window.

Hours of actual work after breaks and changeover. Decimals are fine — 6.5, for example. The same hours are assumed for each person.

Your own observed rate. Nothing is filled in for you and no industry average is used.

I Don’T Know My Rate

Take a period you can remember clearly. Divide the packages completed by the total labour hours spent on them — picking, checking and packing together. Illustrative example: 300 packages ÷ 15 hours = 20 packages per person-hour.

Observed rate: —

Will the work be finished?

Still needed: How many packages need to ship, How many people are working on them, Productive hours per person, Completed packages per person-hour. Nothing is estimated for you, so there is no result yet.

How This Is Calculated

Available labour hours = people × productive hours each. Capacity = those hours × completed packages per person-hour. Remaining = packages − capacity, and the labour hours the workload needs = packages ÷ rate.

A field you leave empty stays unknown and is never counted as a zero, so no result appears until all four figures are entered.

This assumes every person works the same hours at the same rate, with no exceptions, hunting or queues between stations. People needed is always rounded up — you cannot staff part of a person.

Find My Bottleneck

Station-level view: pick, scan/check and pack separately, each with its own rate and its own people. Nothing above is copied in — a whole-team rate is not a station rate, and the same person is never counted in full at two stations.

This Window

Name the period you are planning. Display only.

Workload

Orders, units and packages are three different counts. Nothing here is assumed for you.

Buyer orders in this window.

Physical items picked per order.

Sealed parcels per order. Needed when a pack rate is packages per hour.

Use this instead if you know the parcel count but not the ratio.

Derived: — units · — packages

Rates You Actually See

A productive hour is an hour of that station's work. No rate is prefilled and none is borrowed from anyone else.

Blank blocks the pick station rather than guessing.

Time And People

Headcount is whatever you plan. Nothing is prefilled and there is no suggested mix.

Hours of station work, after breaks and changeover. For example 6.5 of an 8-hour shift.

Shared people

Add anyone who splits the window across stations. Their fractions must add up to 1.0 or less — the same person is never counted in full at two stations.

Where The Line Breaks

Workload hours, capacity hours and the gap, station by station.

Enter this window’s volume, your own rates and the people you plan to have. Blanks stay blank — nothing is assumed.

Capacity math is not a promise that the window finishes on time. Exceptions, hunting and handoff queues are outside this model.

Stop running the warehouse on memory. Address locations, separate incoming from outgoing, label overstock, and keep pick → check → pack handoffs clear — even when your expert takes a day off.
