How to Calculate ROI on Warehouse Automation

Silo² automated storage and retrieval system

Warehouse automation is a significant investment, and stakeholders will want a clear picture of payback before signing off. Here's how to build a credible ROI case.

Start with labor savings

Calculate current labor hours spent on the task you're automating, multiply by fully-loaded hourly cost, then estimate the reduction automation delivers.

Factor in space reclaimed

Automated storage systems like VLM and ASRS often free up significant floor space — value that space at your facility's cost per square foot, or the revenue-generating activity it could support instead.

Account for accuracy and throughput gains

Fewer picking errors and faster cycle times translate into fewer returns, less rework, and higher order capacity without adding headcount.

Key cost and savings factors

Labor cost reduction
Space reclaimed
Error and rework reduction
Throughput capacity gained
Implementation and maintenance cost

The short answer

A credible ROI case combines labor savings, space value, and throughput gains against total implementation cost — most warehouse automation projects in Singapore pay back within 2-4 years depending on scale.

FAQ

Frequently Asked Questions

What's a typical payback period?

Most projects see payback in 2-4 years, though space-constrained facilities with high labor costs can see faster returns.

Should I include maintenance costs?

Yes — ongoing maintenance and support should be included in your total cost of ownership, not just the upfront investment.

What should we measure before the project starts?

Baseline your current picks per hour, error rate, order cycle time, and floor space used per SKU. Without a documented baseline taken before installation, you can't prove the gain afterwards — and this is the single most common gap when projects come up for review.
