AMR and AGV Cost Estimation: Total Cost of Ownership and Cost Per Move

A money-focused breakdown of intralogistics automation cost: what drives cost per move, how to build a defensible TCO quote, and the hidden line items that wreck estimates.

Cost per move is the number buyers actually compare, and it hides a lot. Divide annualized total cost of ownership by annual moves. A fleet with 620,000 dollars amortized cost per year running 1.9 million moves lands at 0.33 dollars per move. Manual tugger handling on the same lane often runs 0.55 to 0.90 dollars once you load labor, so the gap funds the project. The Material Move Cost Calculator builds this per-move figure, but only if your denominator uses realistic utilization, not the vendor's theoretical 24/7 throughput.

Hardware is rarely the biggest line. A mid-range AMR runs 45,000 to 90,000 dollars, and an autonomous forklift 120,000 to 180,000 dollars, but integration, safety, and infrastructure typically add 60 to 120 percent on top. Budget charging stations at 3,000 to 8,000 dollars each, WiFi or 5G coverage upgrades, floor marking, fire-door and elevator interfaces, and WMS or MES integration that can run 40,000 to 150,000 dollars alone. A common estimating error is quoting the sticker fleet price and discovering the true installed number is nearly double.

Labor savings drive the return, so estimate displaced headcount honestly. A fully loaded material handler costs 52,000 to 68,000 dollars per year including benefits, PTO, and turnover, not just the base wage. But automation rarely removes whole people cleanly: displacing 2.5 FTE of a 3 person crew is realistic, while claiming all 3 usually leaves an orphan task that keeps someone on the clock. The Internal Logistics Labor Savings Calculator forces you to net out residual manual work, which is where optimistic quotes lose 20 to 30 percent of the promised savings.

Machine time and energy are small but real recurring costs. At 350 to 600 W average draw and 0.12 dollars per kWh, a robot running 4,000 hours a year burns 170 to 290 dollars in electricity, which is trivial. Battery replacement is not: a lithium pack at 2,000 to 4,000 dollars every 4 to 6 years adds roughly 500 to 900 dollars per robot per year of reserve. Maintenance contracts typically run 8 to 15 percent of hardware cost annually, so a 70,000 dollar AMR carries 5,600 to 10,500 dollars in yearly service.

Overhead and scrap have analogs here even without cutting metal. The intralogistics version of scrap is mispicks, collisions, and blocked routes that force manual recovery. If a fleet handles 1.9 million moves and 0.3 percent need human intervention at 4 minutes each, that is 5,700 recoveries and 380 hours, roughly 12,000 dollars in hidden labor. Downtime from a stalled elevator interface or a congested aisle also erodes the denominator, so a defensible quote reserves 5 to 10 percent of projected moves for exception handling rather than assuming a clean count.

Build the quote as an annualized TCO, not a purchase price. Sum hardware, integration, and infrastructure into installed capital, amortize over a 7 year life with any financing rate, then add annual energy, maintenance, battery reserve, and software subscription. A 22 robot system might total 1.4 million dollars installed, amortize to 200,000 dollars a year, and carry 180,000 dollars in recurring cost, giving 380,000 dollars annual TCO. The AMR ROI Calculator and Autonomous Forklift Payback Calculator turn that into payback and IRR the finance team will accept.

The most expensive estimating mistakes are structural, not arithmetic. Sizing to average demand instead of peak leaves the fleet short and forces emergency manual coverage that erases the business case; use the AGV Fleet Size Capacity Calculator with a peak factor before committing capital. Ignoring charging overhead is the other classic: if 30 percent of the fleet is off-floor charging, your effective cost per move is 40 percent higher than the naive figure. Always cost the fleet you need at peak with realistic availability, not the fleet the spreadsheet allows at 100 percent uptime.

Present the number as a range with named drivers so it survives scrutiny. Quote cost per move at, say, 0.30 to 0.42 dollars, and attribute the spread to utilization (the single biggest swing), labor rate, and integration scope. Show the breakeven against current manual cost per move and the payback in years. Buyers reject single-point quotes that hide assumptions; they approve quotes that state the peak fleet size, the availability assumption, the recovery-rate reserve, and the amortization period, each traceable back to a calculator input they can challenge and adjust.
