Packaging Automation & End-of-Line Systems calculator
Case Packer ROI Calculator
Case Packer ROI tells you how fast an automatic case packing cell pays for itself by dividing the installed project cost by the net annual savings it generates. Packaging engineers and plant managers use it to justify replacing two or three manual case-loading operators with a robotic or wraparound case packer at end of line. The metric matters because case packing is one of the most labor-intensive, repetitive-strain-heavy positions in a plant, and a payback under two years usually clears most capital approval gates. It also frames the conversation with finance in terms they trust: a defined break-even point and a five-year net.
What this calculator does
- Estimate the payback period for an automated case packer by comparing the installed project cost against the labor, rework, and throughput savings it delivers each year.
- Use it when a case packing automation project is competing for capital and you need a quick payback before building a full business case.
- It computes the case packer payback period in years and the net annual and five-year savings after subtracting recurring support costs.
Formula used
- Net annual case packing savings = annual case packing savings - annual case packer support cost
- Case packer payback period = case packer project cost ÷ net annual case packing savings
Inputs explained
- Case packer installed project cost:
- Annual labor and material savings from case packing:
- Annual case packer maintenance and support cost:
How to use the result
- Use it during capital justification, when comparing manual case loading against a robotic, drop, or wraparound case packer at end of line.
- It assumes savings and support costs hold flat year over year and ignores throughput growth, inflation, downtime ramp, and the time value of money, so treat the payback as a screening figure, not a discounted NPV.
Current U.S. benchmarks
- The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
- The producer price index for paperboard and containers stands at 276.831 (BLS, May 2026), up 8.8% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Common questions
- How do you calculate case packer ROI payback? Subtract annual support cost from annual savings to get net annual savings, then divide project cost by that figure. With a $25,000 project, $18,000 savings, and $2,500 support, net savings is $15,500 and payback is $25,000 / $15,500 = 1.61 years.
- What is a good payback period for a case packer? In most consumer-goods and food plants, under 2 years is strong, 2 to 3 years is acceptable, and beyond 3 years needs a non-financial driver like ergonomics or labor scarcity. The 1.61-year example here is well inside the strong range.
- What does net annual case packing savings include? It is gross savings (displaced operator wages, reduced overtime, fewer case-loading errors and product damage) minus the recurring support cost of the machine, such as spares, service contracts, and maintenance labor. In the example that nets to $15,500 per year.
- Case packer payback vs ROI percentage, which should I use? Payback answers how fast you get your money back; ROI percentage answers how much total return you earn. Payback is faster to communicate to operations, while finance often wants both. A 1.61-year payback implies roughly a 62% simple annual return on the net savings.
- Why subtract the support cost instead of using gross savings? A case packer is not free to run; it needs spares, periodic service, and maintenance attention. Using gross savings overstates the return and produces an optimistic payback. Netting out the $2,500 support cost gives the honest $15,500 figure.
