ROI Calculation Methodology

Full transparency on how we estimate warehouse management system ROI. Our methodology, data sources, assumptions, and limitations.

Last reviewed . Savings model and assumptions rechecked.

1. Overview

Our ROI calculator provides preliminary estimates for planning and budgeting purposes. It is not a guarantee of results. The calculator uses industry benchmarks, published research, and data from Rorix Technologies implementations to generate projections based on your inputs.

Important: Calculator results are estimates only. Actual ROI depends on many factors including current processes, implementation quality, team adoption, warehouse complexity, and business conditions. We recommend a detailed assessment for accurate projections.

2. Data Sources

Our calculations draw from the following sources:

  • Industry Research: Published benchmarks from warehouse management industry reports including studies by supply chain research organizations and technology analyst firms (2020 to 2025).
  • Client Implementation Data: Anonymized and aggregated performance data from Rorix Technologies WMS implementations. Sample sizes are limited and may not represent all industries or warehouse types.
  • Standard Industry Formulas: Commonly used warehouse operations metrics and formulas (labor cost per hour, carrying cost percentages, error cost per order) sourced from supply chain management literature.

3. Calculation Methodology

3.1 Labor Efficiency Savings

Labor Savings = Employees × Hourly Rate × 2,080 hrs/year × Efficiency Gain %

Efficiency gain percentages vary by scenario:

  • Conservative: 25% (representing lower-end industry outcomes)
  • Typical: 35% (representing mid-range outcomes, typical range: 30% to 40%)
  • Optimistic: 45% (representing best-observed outcomes under ideal conditions)

3.2 Error Reduction Savings

Error Savings = Annual Orders × (Current Error Rate - Improved Rate) × Cost Per Error ($50)

The $50 cost-per-error is an industry average that includes re-shipping, returns processing, customer service, and lost goodwill. Actual costs vary by industry from $10 to $200+ per error.

3.3 Inventory Carrying Cost Reduction

Inventory Savings = Warehouse Sq Ft × $100/sqft × 25% Carrying Cost × Reduction %

The $100/sqft inventory value is a rough estimate. The 25% annual carrying cost rate is a standard industry figure that includes storage, insurance, obsolescence, and capital costs.

3.4 Implementation Cost Estimate

Estimated Cost = MAX($25,000, MIN(Warehouse Sq Ft × $2, $150,000))

This is a simplified cost model. Actual WMS implementation costs vary significantly based on features, integrations, customization, and deployment complexity. Contact us for accurate pricing.

4. Scenario Definitions

Conservative (Lower End)

  • 25% efficiency improvement
  • Final error rate: 0.3%
  • 8% inventory reduction

Represents outcomes at the lower end of observed results. Appropriate for warehouses with complex operations or limited change management.

Typical Range

  • 35% efficiency improvement (range: 30% to 40%)
  • Final error rate: 0.15% (range: 0.1% to 0.3%)
  • 12% inventory reduction (range: 10% to 18%)

Represents the middle range of observed results. Most appropriate for standard warehouse operations with good implementation practices.

Optimistic (Upper End)

  • 45% efficiency improvement
  • Final error rate: 0.1%
  • 18% inventory reduction

Represents best-observed outcomes. Appropriate only under ideal conditions with excellent implementation, strong team adoption, and significant room for improvement.

5. Variability & Limitations

All results include a ±20% variability range to account for real-world differences. Even with this range, actual results may fall outside these projections.

Key Variables Not Accounted For

  • Current warehouse layout and organization
  • Team experience and training speed
  • Change management effectiveness
  • Integration complexity with existing systems
  • Product mix and handling requirements
  • Seasonal variations in order volume
  • Ongoing maintenance and optimization needs
  • Industry-specific regulatory requirements
