Warehouse cost calculator
Annual warehouse operating cost — rent, utilities, labour, equipment, insurance, and maintenance — per square metre.
Calculator logisticsLogic updated April 2026
This calculator builds the total annual cost of operating a warehouse from its constituent line items — rent, utilities, labour, equipment, insurance, and maintenance. It derives a per-square-metre cost and an effective cost adjusted for occupancy, exposing the drag that under-utilised space puts on your overall cost structure.
How this is calculated
Formula
annualRent = monthlyRentPerSqm × sqm × 12 ; annualUtilities = monthlyUtilitiesPerSqm × sqm × 12 ; annualLabour = staff × salary ; total = rent + utilities + labour + equipment + insurance + maintenance ; effectiveCostPerSqm = total / (sqm × occupancy)Step-by-step
- Calculate annual rent: monthly rent per sqm × warehouse size × 12 months
- Calculate annual utilities the same way using utilities cost per sqm
- Calculate annual labour: number of staff × fully-loaded annual salary per staff member
- Add annual equipment cost (depreciation + service, not the purchase price)
- Add annual insurance and maintenance
- Sum all six components for total annual cost
- Divide total by warehouse size for cost per sqm; divide by (size × occupancy rate) for effective cost per sqm in active use

Assumptions & limitations
What this calculator assumes
- Rent and utilities are charged per square metre of gross floor area
- Labour cost is the sum of staff count multiplied by fully-loaded annual salary
- Occupancy rate reflects the usable fraction of floor area in active use
- Effective cost per sqm divides total cost by occupied sqm to expose utilisation drag
- Annual equipment cost is amortised depreciation plus service, not the purchase price
What this calculator doesn’t account for
- Doesn't model labour overtime, peak-season casual staff, or shift patterns
- Doesn't factor in inventory holding cost (use the inventory holding cost calculator alongside)
- Doesn't include any fees or fines for environmental compliance
- Doesn't model utility price changes within the year
- Doesn't account for capital expenditure on warehouse improvements
Worked example
A 5,000 sqm warehouse with $15/sqm/month rent, $3/sqm/month utilities, 12 staff at $55,000/year fully-loaded, $30,000/year equipment, $25,000 insurance, $20,000 maintenance, 80% occupancy.
| Input | Value |
|---|---|
| Warehouse size / occupancy | 5,000 sqm / 80% |
| Monthly rent / utilities per sqm | $15 / $3 |
| Staff (count / fully-loaded salary) | 12 / $55,000 |
| Equipment / Insurance / Maintenance | $30,000 / $25,000 / $20,000 |
Total annual cost: $1,815,000 — Per gross sqm: $363 — Effective per occupied sqm: $454
Rent: $15 × 5,000 × 12 = $900,000. Utilities: $3 × 5,000 × 12 = $180,000. Labour: 12 × $55,000 = $660,000. Equipment + insurance + maintenance = $75,000. Total: $1,815,000. Per gross sqm: $363/year. With 80% occupancy, only 4,000 sqm is in active use, so effective cost per occupied sqm is $454 — that's the cost actually being earned by your stored goods. The 20% unoccupied space is silent drag.
Frequently asked questions
What costs make up warehouse operations?
Six main buckets: rent (typically 40–60% of total), labour (20–35%), equipment depreciation and service (5–15%), utilities (5–10%), insurance (2–5%), and maintenance (2–5%). The exact mix depends on automation level — heavily-automated warehouses shift cost from labour to equipment. Specialised warehouses (cold storage, hazardous materials) shift cost into utilities and insurance.
How do I calculate cost per unit stored?
Divide total annual warehouse cost by the number of units (or pallet positions, or cubic metres) actively stored across the year. A warehouse costing $1.8M/year storing an average 50,000 units has a per-unit storage cost of $36/year. This is the warehouse-only figure — pair with the inventory holding cost calculator to add capital and obsolescence components for the full per-unit holding cost.
Fixed vs variable warehouse costs?
Most warehouse costs are fixed in the short term. Rent, insurance, equipment depreciation, and base labour stay roughly constant whether you're storing 1,000 units or 10,000. Utilities and overtime labour scale somewhat with activity. The high fixed-cost structure means warehouse cost per unit drops dramatically as utilisation rises — and rises sharply when utilisation falls.
How does automation affect warehouse costs?
Automation typically shifts the cost mix from labour to equipment depreciation. A heavily-automated facility may have 60% equipment cost and 15% labour, vs 25% equipment and 35% labour for a manual operation. Total cost can be similar at high utilisation, but automated facilities have less labour flexibility — they're more expensive at low utilisation and cheaper at high utilisation.
What is occupancy rate?
The fraction of the warehouse actually in active storage or operation. A 5,000 sqm building with 4,000 sqm of stored goods and 1,000 sqm of unused space has 80% occupancy. The effective cost per occupied sqm is the figure that tells you what each productive square metre genuinely costs — which is often 20–40% higher than the gross-area figure that gets quoted on a lease.
