Discover the real financial impact of implementing a Warehouse Management System. Get personalized savings estimates in minutes.
Based on published industry benchmarks and our delivered WMS projects.
Get your ROI breakdown in seconds, not days of manual calculations.
See savings from labor efficiency, error reduction, and inventory optimization.
Understand where you’ll see the biggest gains and fastest payback.
Our calculator uses published industry averages, and every constant behind it is documented on our methodology page. Results carry a ±20% range to reflect real-world variation, and actual results can still fall outside it.
We calculate savings from labor efficiency (35% in the typical scenario, applied to the 65% of warehouse hours a WMS touches, with 50% of that gain counted as cash), error reduction (down to a 0.15% error rate), and inventory carrying cost (12% reduction), net of an annual run cost of 18% of the build.
Build plus rollout runs 3 to 6 months depending on build scope, and the calculator counts payback from project start. We can provide a detailed timeline during consultation.
You’ll instantly see your detailed ROI results. We’ll also email you a PDF report and our team will reach out within 24 hours to discuss implementation details.

Schedule Free ConsultationThe calculator turns five inputs, warehouse size, monthly orders, current error rate, hourly labor cost, and employee count, into an estimate of net annual savings. It sums labor savings on the 65% of warehouse hours a WMS touches, error savings at $50 per mis-shipped order, and inventory carrying-cost reductions, then deducts an 18% annual run cost and a modeled build cost to report payback from project start and five-year net value.
On these inputs the calculator reports $394,660 in net annual savings (range $314,000 to $475,320 at ±20%), a 5 month payback from project start, a 90% error reduction, and $1,793,747 in five-year net value.
| Assumption | Value | Used for |
|---|---|---|
| Error cost per order | $50 | Cost of each mis-picked or mis-shipped order |
| Work hours per year | 2,080 | Annual payroll per employee |
| Inventory value per sq ft | $100 | Estimating the inventory on hand |
| Inventory carrying cost | 25% per year | Base for carrying-cost savings |
| Addressable labor share | 65% | Share of warehouse hours a WMS actually touches |
| Maximum error cut | 90% | The error rate is never cut by more than 90% |
| Annual run cost | 18% of build cost | Hosting, support, and licenses, deducted from savings |
| Variability band | ±20% | Low and high range on the headline savings figure |
| Scenario | Efficiency gain | Target error rate | Inventory reduction | Labor realization |
|---|---|---|---|---|
| Conservative | 25% | 0.3% | 8% | 35% |
| Typical | 35% | 0.15% | 12% | 50% |
| Optimistic | 45% | 0.1% | 18% | 65% |
Labor realization is the share of saved hours that becomes cash rather than absorbed capacity. The displayed efficiency ranges are 20-30%, 30-40%, and 40-50% respectively.
| Component | How it is priced |
|---|---|
| Base | $20,000 flat |
| Floor area | $0.30 per sq ft, capped at $45,000 |
| Order volume | $0 below 5,000 orders a month, $10,000 from 5,000, $30,000 from 20,000, $80,000 from 100,000 |
| Team size | $150 per employee, capped at $30,000 |
| Integrations | $8,000 each (WMS assessment variant only) |
| Real-time features | $10,000 each (WMS assessment variant only) |
| Rollout period | 3 months below a $45,000 build, 4 from $45,000, 5 from $80,000, 6 from $150,000, 7 from $200,000 |
Payback is counted from project start, so the rollout period is added before savings begin. The model is calibrated to the published WMS build bands: typical single-site profiles land in the $30,000 to $64,000 band, multi-site and RFID-scale profiles in $80,000 to $180,000+, capped at $250,000.
These are the same constants the calculator above runs on, shared with the WMS assessment and the PDF report. See the full method
