Warehouse Calculators | Crowe Services

Warehouse Space Calculator

Estimate dock space, pallet storage capacity, and overall warehouse area requirements based on your throughput, pallet dimensions, and racking configuration.

1. Dock & Staging Space

Space required to receive, stage, and unload inbound loads

Throughput

Number of loads received per day

Size of load (pallets per load)

Time to unload per load (min)

Time for staging prior to put-away (min)

Work shift per day (hrs)

Pallet footprint (dock calc)

Width of pallet (m)

Depth of pallet (m)

Dock space required – m²

Working & travel area (×2) – m²

Total dock area required – m²

Dock space = ROUNDUP[(loads × (unload + staging time) ÷ 60) ÷ shift hours] × (load size × pallet width × pallet depth)

2. Pallet Storage Location

3. Warehouse Area Allocation

Total warehouse footprint by activity type

Area	m²	% of total	Typical range
Dock & staging activities	–	–	10% – 15%
Storage & handling activities	–	–	70% – 80%
Non-activity area (e.g. office)	–	–	3% – 5%
Total warehouse area	–	100%	–

3PL Warehousing Cost Calculator

Estimate the annual operating cost of a 3PL warehousing arrangement across storage, inbound/outbound pallet handling, and container loading/unloading — in your base currency and a second reporting currency.

Currency & Assumptions

Set your quoting currency, a reporting currency, and the pallets-per-container assumption used below

Pallets per 40ft container

Pallet footprint assumption from the source workbook: 120cm × 80cm × 150cm.

1

Storage Cost

Cost of holding pallet positions across the year

Inputs

Number of pallet locations

Cost per pallet (SGD) per day

Cost (SGD) yearly –

Cost (EUR) yearly –

Yearly cost = pallet locations × cost per pallet per day × 365 days

2

Inbound Pallet Movement

Cost of receiving and putting away inbound pallets

Inputs

Number of pallets daily

Days/month with inbound operations

Cost per pallet (SGD)

Cost (SGD) yearly –

Cost (EUR) yearly –

Yearly cost = pallets/day × cost/pallet × days/month × 12 months

3

Outbound Pallet Movement

Cost of picking and dispatching outbound pallets

Inputs

Number of pallets daily

Days/month with outbound operations

Cost per pallet (SGD)

Cost (SGD) yearly –

Cost (EUR) yearly –

Yearly cost = pallets/day × cost/pallet × days/month × 12 months

4

Container Loading

Forklift cost to load outbound containers, based on outbound pallet volume

Inputs

Containers to load daily (calculated)

Days/month with outbound operations

Cost per 40ft container (SGD) (forklift)

Cost (SGD) yearly –

Cost (EUR) yearly –

Cost = containers/day × days/month × cost/container.

Matches the source workbook exactly, but note: unlike the pallet-movement sections above, this figure is not multiplied by 12 in the original sheet — so despite being labelled "yearly," it's really one month's cost carried through as the annual figure. Worth confirming with whoever built the original workbook whether that's intentional.

5

Container Unloading

Forklift cost to unload inbound containers, based on inbound pallet volume

Inputs

Containers to unload daily (calculated)

Days/month with inbound operations

Cost per 40ft container (SGD) (forklift)

Cost (SGD) yearly –

Cost (EUR) yearly –

Cost = containers/day × days/month × cost/container. (Also not ×12 — see note in Container Loading above.)

Fixed vs. the source workbook: unloading cost now uses its own cost per container input above — the original sheet's unloading formula accidentally reused the loading section's cost cell (harmless there only because both defaulted to 300).

Weighted Factor Matrix Calculator

Score and rank competing options (sites, vendors, DC locations, etc.) against custom weighted factors — weightings, scoring bands, and per-option scores feed a single weighted total.

1. Factors & Weightings

Rename each factor and set its weighting — weightings should sum to 100%

–

Each factor is scored one of two ways: 1–5 rating (converted to 20/40/60/80/100 points), or a dollar value banded against thresholds set in the scoring table below (lower-is-better or higher-is-better). Set the type per factor here.

2. Scoring Bands

Dollar thresholds that convert a raw $ value into points for each dollar-type factor

Points	Lower-is-better factor(s)value ≤ threshold scores these points	Higher-is-better factor(s)value ≥ threshold scores these points

1–5 rating factors always convert as 1→20, 2→40, 3→60, 4→80, 5→100 points, and don't use this table.

3. Options

Raw input per option, per factor

4. Weighted Scores

Per-factor points and overall weighted total, ranked highest to lowest

Volume Availability Calculator

Model how a staff crew's processing capacity catches up with arriving volume through a shift — ramp-up, breaks, and idle time included — and see the completion time before the day starts.

1. Volume Arrivals

When volume becomes available for processing, and how much

Time	Volume

Volume is capped at 4,500 units total per the source model's design limits. Times use 24-hour format (e.g. 14:30).
