How to Maximize Your Packaging Automation ROI

October 21, 2026

Budget season is here, and many plant managers are asking the same question about the packing station. Is it time to stop forming and sealing cases by hand? A clear packaging automation ROI estimate answers that question with numbers, not hunches. In this guide, we walk through the math behind a realistic payback period. We also explain when a case erector earns its keep and how to judge end-of-line automation for a mid-size line.

The Three Drivers of Packaging Automation ROI

Most capital requests lean only on labor savings. However, a strong case counts three sources of value. Start with labor, then add throughput and quality.

Labor Cost Offset

First, use the fully burdened cost of each position, not just the hourly wage. According to the Bureau of Labor Statistics, benefits make up about 30% of total employer compensation costs. So a $20 wage really costs about $28.50 per hour.

Next, count the hours your team spends forming, taping, and moving cases. Lantech estimates one person can form about three cases per minute, minus breaks. In most plants, automation moves those people to inspection, packing, or palletizing. That shift matters, because PMMI reports that 60% of CPG companies cite labor shortages as a major driver of automation.

Throughput Gain

Many case erectors run about 8 to 30 cases per minute. Still, speed only adds value if case forming is your true bottleneck. If a labeler or coder limits the line, a faster erector will just wait. For that reason, check your OEE data first. Our recent post on throughput vs. uptime explains how to find the real constraint.

Error and Rework Reduction

Hand-formed cases vary in squareness and seal quality. As a result, plants see crushed pallets, open flaps, and unreadable codes. Square cases also help case coders and labelers hit the same spot every time. Add the cost of rework, returns, and lost product to your savings column.

A Simple Packaging Automation ROI Formula

The payback period is the core number most finance teams want to see. Here is the basic formula:

Payback period (months) = Total installed cost ÷ Monthly net savings

Total installed cost should include the machine, freight, integration, guarding, training, and starter spare parts. Meanwhile, net savings means labor, throughput, and quality gains minus new costs like tape, power, and service.

For example, say a system costs $90,000 installed. It frees two operator positions, one per shift, worth about $9,900 per month. After new tape, power, and service costs, net savings land near $7,500 per month. In that case, payback takes 12 months. These numbers are only an illustration, so run your own. Lantech notes that most case erecting projects pay back within three years.

Also, ask your tax advisor about timing. Under IRS Rev. Proc. 2025-32, the 2026 Section 179 expensing limit is $2,560,000. Generally, you must place the equipment in service by year-end to claim it.

Factor In Changeover and Product Mix

Changeovers can quietly erase end-of-line automation savings. To estimate the impact, multiply minutes per changeover by changeovers per week. Then subtract that lost time from your throughput gain.

Product mix matters too. A uniform case sealer needs manual adjustment for each new box size. In contrast, a random case sealer adjusts on its own, which suits mixed-SKU lines. Likewise, highly seasonal runs may not keep an automated system busy enough to pay off.

When Semi-Automation Is the Better Fit

Full end-of-line automation is not always the right first step. Lantech uses about 600 cases per day as a general break-even point for an automatic case erector. Below that volume, a semi-automatic case sealer often delivers a shorter payback period.

In this setup, operators still form cases by hand, but the machine seals every box the same way. Later, you can add a case erector as volume grows. This staged approach keeps capital costs low while your data builds the case for the next step.

Turn Packaging Automation ROI Into a Capital Request

Before you submit your 2027 budget, gather these items:

• Current cases per day, shifts, and labor hours at the packing station
• Fully burdened labor cost per position
• Downtime, rework, and damage logs from the last 12 months
• Quotes that include installation, training, and spare parts
• A service and preventive maintenance plan for the new equipment

Mid-America Packaging helps plants build this picture before they buy. We supply Eastey case erectors and sealers, Hitachi and Squid Ink case coders, and Evolabel labelers. Our service team, rebuild center, and field offices across the region keep that equipment running after install.
