Build an initial automation business case in minutes

Automation should be justified by what it changes in your operation—not by a generic industry percentage.

Enter your labour costs, overtime, errors, proposed investment and expected improvements. The calculator will estimate the commercial effect while keeping every assumption visible.

Calculate your warehouse automation return

Use annual figures wherever possible. Optional fields can be left at zero.

Build a credible calculation

What should be included in warehouse automation ROI?

A useful business case needs the full project cost, recurring operating costs and measurable operational benefits.

01

Complete investment

Equipment, controls, software, installation, integration, site work, training and contingency.

02

Ongoing cost

Preventive maintenance, software licences, energy, spares, consumables and technical support.

03

Measurable benefit

Labour hours, overtime, agency labour, errors, throughput, avoided recruitment and capacity constraints.

Interpret the result properly

Labour savings do not always mean redundancies

Released labour creates value in several different ways.

Examples of genuine labour value

  • Reduced agency and temporary staffing
  • Lower regular overtime
  • Avoided future recruitment
  • More output without adding headcount
  • Employees moved away from repetitive handling
  • Experienced staff reassigned to higher-value work

Throughput only has value when you can use it

Additional capacity becomes commercially relevant when it allows you to accept more volume, extend cut-off times, remove backlogs, win contracts, avoid overflow space or postpone a building expansion.

Enter the expected contribution or gross profit from that additional capacity—not the headline sales revenue.

Understand the outputs

Payback and ROI are not the same thing

P

Payback period

The estimated time required for cumulative net benefit to recover the initial investment.

A

Annual return

One year of net benefit shown as a percentage of the initial investment.

5

Five-year ROI

Cumulative five-year net benefit after the initial project investment has been deducted.

What a warehouse automation case could look like

These figures are for explanation only. Real decisions should use validated process data and supplier quotations.

Initial investment

  • Equipment and controls: £350,000
  • Installation and integration: £65,000
  • Site preparation and training: £35,000

Total: £450,000

Annual benefit

  • Labour savings: £180,000
  • Overtime savings: £25,000
  • Error reduction: £15,000
  • Capacity contribution: £30,000

Gross benefit: £250,000

Estimated result

  • Annual running cost: £30,000
  • Net annual benefit: £220,000
  • Payback: approximately 24.5 months
  • Five-year ROI: approximately 144%
Common questions

Warehouse automation ROI FAQs

How is warehouse automation ROI calculated?
The calculator estimates labour, overtime, error, capacity and other annual benefits. It subtracts recurring automation costs and compares the resulting net benefit with the initial investment.
What is a good warehouse automation payback period?
There is no universal threshold. The acceptable period depends on risk, project life, strategic value, financing, utilisation and the organisation’s investment criteria. A shorter payback generally reduces exposure, but it does not show the total long-term value.
Should redeployed labour count as a saving?
Only where the released hours create measurable value, such as avoiding recruitment, reducing overtime, increasing output without adding headcount or moving employees into work that would otherwise need more labour.
Should increased revenue be included?
Do not enter additional revenue directly. Use the contribution or gross profit expected from the additional volume after variable costs have been deducted.
Does the calculator include maintenance costs?
Yes. Maintenance, software, energy, spare parts and other recurring costs are entered separately and deducted from the gross annual benefit.
Can this be used for conveyors, sorters and AMRs?
Yes. The same business-case structure can be applied to conveyors, parcel sortation, AMRs, robotics or a wider integrated automation system.
Is this a formal financial appraisal?
No. It is an early operational estimate. A final approval may also require validated quotations, depreciation, tax treatment, financing, net present value, internal rate of return and a full risk assessment.
