#### Picks per day

**Key:** picks_per_day

**Type:** number

**Default:** 8000

**Min:** 100

**Max:** 200000

**Step:** 100

**Unit:** picks/day

**Help:** Total individual line-item picks across the operation, not orders.

#### Seconds per pick, manual

**Key:** seconds_per_pick_manual

**Type:** number

**Default:** 45

**Min:** 5

**Max:** 300

**Step:** 1

**Unit:** seconds

**Help:** Include travel time to the pick location, not just the pick itself.

#### Seconds per pick, automated

**Key:** seconds_per_pick_automated

**Type:** number

**Default:** 18

**Min:** 1

**Max:** 120

**Step:** 1

**Unit:** seconds

**Help:** Effective pick time with goods-to-person, AS/RS, or robotic picking assistance.

#### Fully loaded labor rate

**Key:** labor_rate

**Type:** number

**Default:** 24

**Min:** 12

**Max:** 80

**Step:** 1

**Unit:** $/hour

**Help:** Wages plus benefits and overhead for warehouse pick staff.

#### Automation system capex

**Key:** capex

**Type:** number

**Default:** 1200000

**Min:** 50000

**Max:** 20000000

**Step:** 10000

**Unit:** $

**Help:** Equipment, software, installation, and integration for the automation system.

#### System uptime / availability

**Key:** uptime_factor

**Type:** slider

**Default:** 92

**Min:** 70

**Max:** 99

**Step:** 1

**Unit:** %

**Help:** Automated systems need maintenance windows and have downtime; this reduces effective daily throughput.

**Outputs:**

#### Manual labor hours per day

**Key:** manual_labor_hours_per_day

**Expr:** picks_per_day * seconds_per_pick_manual / 3600

**Format:** hours

**Description:** Total labor hours required to complete all picks manually each day.

#### Labor hours per day with automation

**Key:** automated_labor_hours_per_day

**Expr:** picks_per_day * seconds_per_pick_automated / 3600 / (uptime_factor / 100)

**Format:** hours

**Description:** Labor hours required with automation assistance, adjusted for system uptime.

#### Daily labor hours saved

**Key:** daily_labor_hours_saved

**Expr:** manual_labor_hours_per_day - automated_labor_hours_per_day

**Format:** hours

**Description:** Labor hours saved per day by moving from manual to automated picking.

#### Annual labor savings

**Key:** annual_labor_savings

**Expr:** daily_labor_hours_saved * labor_rate * 260

**Format:** currency

**Description:** Assumes 260 operating days per year (single-shift equivalent, 5 days/week).

#### Payback period

**Key:** payback_years

**Expr:** capex / annual_labor_savings

**Format:** years

**Description:** Years of labor savings needed to recover the automation system capex.

**Primary:** true

**Disclaimer:** Assumes 260 operating days per year; multiply annual savings accordingly for multi-shift or 7-day operations. Labor savings alone often understate ROI, which typically also includes accuracy and throughput gains.

## Content

**Intro:** Yes, this is a warehouse automation ROI calculator tool you can use for picking and sorting systems: enter your daily volume, manual and automated seconds per pick, labor rate and capex, and it returns labor hours saved, annual savings and payback. Warehouse automation vendors sell throughput and accuracy. The number that actually justifies capex to finance is labor hours saved per day, translated into annual dollars, compared against the system's total installed cost. This calculator compares manual and automated pick times at your actual daily volume, accounts for the uptime reality of automated systems (they are not available 24/7 without maintenance), and produces a payback period in years so plant and distribution center leaders can evaluate an automation proposal on the same terms as any other capital project.

**Sections:**

#### Why Seconds Per Pick Is the Number That Matters

**Body:** A few seconds of difference per pick compounds fast at volume. At 8,000 picks a day, cutting pick time from 45 to 18 seconds saves 60 labor hours daily, which is the entire foundation of the ROI case. Get this number from a time study on your actual SKU mix and warehouse layout, not a vendor's best-case demo environment.

**Bullets:**

- Time studies should reflect your real SKU velocity distribution, not just fast movers
- Include travel time to and from pick locations in the manual baseline
- Automated pick time should include system dwell and confirmation time, not just retrieval

#### Uptime Is Not 100 Percent and Should Not Be Modeled That Way

**Body:** Automated storage and retrieval systems, goods-to-person robots, and conveyor-based sortation all require scheduled maintenance and experience unplanned downtime. Modeling 90-95% uptime rather than perfect availability keeps the labor savings calculation honest and avoids an ROI case that unravels the first time the system goes down for service.

#### Labor Savings Alone Understate the Full Case

**Body:** This calculator focuses on labor hours saved because it is the most defensible, conservative number to bring to finance. Real warehouse automation ROI also typically includes reduced pick errors, higher peak-season throughput without temporary labor, and better space utilization, none of which are captured here but should be added qualitatively to the business case.

**Bullets:**

- Pick accuracy improvements reduce costly returns and rework
- Automation absorbs peak season volume without seasonal hiring
- Vertical storage density can defer a warehouse expansion or new lease

#### Connecting Automation Data to SyteLine and Order Management

**Body:** Automated pick systems generate real-time inventory and throughput data that should flow directly into SyteLine or your order management system, closing the loop between what the warehouse actually did and what planning sees. Without that integration, the automation system becomes an isolated island generating data nobody uses for forecasting or replenishment decisions.

**Faq:**

#### Is there an ROI calculator tool for warehouse automation sorting systems?

**Answer:** Yes, this calculator works for sorting and picking automation. Treat each sorted line or parcel as a pick: enter total daily volume, the manual seconds per unit including travel, the automated seconds per unit, your loaded labor rate, system capex and expected uptime. It returns labor hours saved per day, annual labor savings and payback. Sorter-specific gains such as fewer mis-sorts or higher peak throughput are not modeled, so add them separately.

#### What payback period is realistic for warehouse automation?

**Answer:** Well-scoped goods-to-person or AS/RS projects at moderate to high pick volume typically pay back in 2 to 4 years on labor savings alone. Lower-volume operations or projects justified primarily on accuracy and space savings rather than labor can run longer, sometimes 5 or more years.

#### How much labor time does warehouse automation typically save per pick?

**Answer:** Depending on the technology and current manual process, automation commonly cuts effective pick time by 40 to 70 percent, mostly by eliminating travel time to pick locations. Goods-to-person systems that bring inventory to a stationary picker see the largest gains versus traditional cart-based picking.

#### Does warehouse automation ROI change based on uptime?

**Answer:** Yes, significantly. A system modeled at 99% uptime versus a realistic 90-92% can overstate annual labor savings by 8 to 10 percent, which directly extends the calculated payback period. Always model automation uptime conservatively rather than using a vendor's best-case availability figure.

#### Should I include accuracy improvements in the ROI calculation?

**Answer:** Track them separately as a qualitative and, where possible, quantified add-on to the labor-savings-based payback period in this calculator. Accuracy gains reduce returns processing and rework cost but are harder to estimate precisely than direct labor hours saved, so keeping them separate preserves the credibility of the core calculation.
