How do you calculate end-of-line system payback period?

Subtract annual support cost from annual savings to get net annual savings, then divide project cost by that. With a $25,000 project, $18,000 savings, and $2,500 support, net is $15,500 and payback is 25,000 / 15,500 = 1.61 years.

What is a good payback period for packaging automation?

Many manufacturers fund end-of-line projects with payback under two to three years. The 1.61-year payback in the example is strong and would clear most capital thresholds comfortably.

What is the five-year net savings here?

It's net annual savings times five minus the project cost. With $15,500 net per year over five years less the $25,000 investment, the five-year net is $52,500.

Why subtract annual support cost from savings?

Service contracts, spares, and added utilities recur every year and eat into the gross benefit, so netting them out gives the true cash the project frees up and a realistic payback.

Payback period vs. ROI: which should I use?

Payback answers how fast you recover cash; ROI or NPV answers how much total value the project creates over its life. Use payback as a quick screen, then NPV for final capital decisions on larger spends.

Does this calculator account for the time value of money?

No. It's a simple payback that treats every future dollar as worth a present dollar. For long-lived or high-value projects, follow up with a discounted-cash-flow analysis.

Packaging Automation & End-of-Line Systems calculator

End-of-Line System ROI Calculator

End-of-line system ROI measures how fast an investment in palletizing, case packing, or load-securing automation pays for itself, expressed as a payback period in years after netting out ongoing support cost. Plant managers and capital-approval committees use it to rank competing end-of-line projects and to set a defensible go/no-go threshold. Because end-of-line automation typically displaces labor and reduces transit damage, the savings are usually steady and quantifiable, which makes payback a clean first-pass screen. A sub-two-year payback is the kind of number that gets projects funded.

What this calculator does

Estimate the payback period for a full end of line system by weighing the installed cost against the labor, damage, and throughput savings it delivers each year.
Use it when an integrated end of line system goes to the capital committee and the savings story has to hold up.
It computes the payback period by dividing project cost by net annual savings (gross savings minus annual support cost) and also returns the five-year net.

Formula used

Net annual end of line savings = annual end of line savings - annual end of line support cost
End of line system payback period = end of line system project cost ÷ net annual end of line savings

Inputs explained

End of line system project cost:
Annual end of line savings:
Annual end of line support cost:

How to use the result

Use it to screen a proposed end-of-line automation purchase, to compare two vendor quotes, or to set a capital approval threshold.
Simple payback ignores the time value of money and assumes savings stay flat, so it understates the appeal of projects with growing benefits and overstates those whose savings erode.

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.
