Warehouse Automation ROI Calculator
Estimate payback period, NPV, and lifetime savings for AMRs, AS/RS, conveyors, robotic picking, and WMS upgrades. Pre-loaded with 2026 industry capex and labor benchmarks so you can pressure-test a vendor quote in 60 seconds.
Start with a project preset
Pick the automation type closest to your project — capex, opex, FTE replacement, and useful life will pre-fill with 2026 industry medians.
Project Economics
Equipment + install + integration + initial training. Include sales tax + freight.
Maintenance, software subscriptions, energy, consumables, vendor support.
US federal corp rate is 21%. Add ~5% for typical state combined effect if relevant.
Savings & Productivity Inputs
Use the Labor Cost Estimator to dial in a defensible loaded rate for your region.
Error cost = chargebacks, return shipping, refurbishment, and the labor to fix mis-picks.

How to use this calculator
Start with a preset that resembles your project. Each preset loads 2026 industry-median capex, opex, FTE replacement, productivity lift, error reduction, and useful life. The presets are directional — they will get you to a defensible first-pass number, not a CFO-ready financial model.
Override the inputs that you actually have data for. Capex is the single biggest swing factor — once you have a real vendor quote, plug it in. FTE replaced is the second-most-sensitive input, and the one CFOs scrutinize hardest. Use a conservative number that reflects positions you can actually attrit or redeploy, not the theoretical headcount the vendor diagrams.
Set a discount rate that matches your finance team’s hurdle rate (typically 8–12% for mid-size logistics operators). The NPV will turn negative if the discount rate climbs above the project’s implied IRR, which is a useful pressure test. If your project shows a positive NPV at 15%+, you have real margin of safety.
Read the cumulative cash-flow chart for the storyline you will tell finance: capex out the door in Year 0, payback crossover at year X, accumulating value through year Y. If the discounted (blue) bars stay below zero across the chart, the project does not clear your hurdle rate even if the simple payback looks fine.

2026 automation payback benchmarks
Industry payback medians vary widely by automation type. The table below summarizes the typical range we see across mid-size operators in 2026. Use it as a sanity check on your calculator output — if your inputs produce a payback far outside these bands, revisit your assumptions.
| Automation Type | Typical Capex | Typical Payback |
|---|---|---|
| AMR pick-assist (10 robots) | $300K–$450K | 8–14 months |
| Automated packaging line | $300K–$500K | 12–24 months |
| WMS upgrade + slotting | $150K–$400K | 14–30 months |
| Conveyor + cross-belt sortation | $700K–$1.2M | 2–3 years |
| Robotic piece-picking cell | $400K–$500K | 2–4 years |
| Goods-to-person AS/RS (compact) | $1M–$3M | 3–5 years |
| Full integrated automation (high-volume) | $5M–$25M+ | 4–7 years |
