When a robotic palletizer pays off in Mexico: how many shifts and people it takes

Target Robotics builds palletizers, and this table is going to cost it some quotes. On Mexican wages, a robot pays for itself from 3 shifts with 2 people per shift; on one shift, it barely does. We’d rather publish when a robotic palletizer pays off and when it doesn’t, including the rows that don’t help us sell, because the math takes four numbers and your finance team is going to run it anyway.

When a robotic palletizer pays off in Mexico

From 3 shifts with 2 people per shift. The more people the cell frees from stacking and the more hours it runs, the sooner it pays for itself. These are the months of payback counting labor only (Target Robotics calculation with assumptions):

The assumptions, so you can plug in yours: fully loaded cost of MXN 14,000 to MXN 19,000 per person per month in 2026, with the detail in the cost of manual palletizing in Mexico; MXN 18.50 to the dollar; 71% fewer operators, which is the average goal of palletizing projects according to HowToRobot (March 27, 2026, a base of more than 600 automation projects), with no measurement in Mexican plants. Maintenance, financing and taxes are left out, along with scrap and injuries.

The 71% is the weakest assumption in the table. If the reduction on your line reaches 50%, multiply the months by 1.42: at 3 shifts with 2 people and a US$100,000 cell, the 23 to 31 months become 32 to 44 (same calculation).

The number of people you free from stacking weighs more than the price of the machine. Going from 2 to 12 people makes payback 6 times shorter. Going from US$250,000 to US$100,000, 2.5 times.

The columns are calculation points: Target Robotics does not publish a price yet. As a public reference, Kaufman advertises US$175,000 to US$550,000 per system and CSi its s-Pal from 95,000 euros, about US$120,000 (both checked November 3, 2026). Kaufman ties its range to plant space, end-of-arm tooling, customer specifications, controls, safety and case infeed. The breakdown for Mexico is in what moves the price of a robotic palletizer.

How much can I pay for a cell and still have it pay off?

The same math in reverse, in rounded dollars (Target Robotics calculation with the same assumptions):

With 12 people, the 24-month range already touches the US$175,000 floor Kaufman publishes. With 2 people, even 36 months falls short of the entry-level cobot Robotiq publishes: from US$85,000, with 35 kg and up to 13 cycles per minute (checked November 3, 2026).

Which plants should get a quote now?

From 3 shifts with 2 people per shift it is already worth requesting a quote: with a US$100,000 cell, that means 23 to 31 months. With 4 or more people per shift, or several lines that together add up to 8 to 12 people on payroll, a US$175,000 cell takes 20 to 41 months on labor.

It counts in favor if the case or bag comes close to the 25 kg for men or the 20 kg for women set by NOM-036-1-STPS-2018, Mexico’s federal standard on manual handling (DOF, the official gazette, November 23, 2018), or if cumulative mass approaches the 10,000 kg per 8-hour workday that standard sets, because then the crew has to grow or the load has to change. It also counts if opening a third shift is already in the plan: run the math with the shifts you are going to run.

A reference for scale: 8 cases of 12 kilos per minute, for 7 effective hours, make 40 metric tons per shift (Target Robotics calculation with assumptions). Read per person, that limit calls for more than 4 people per shift, and a plant with that line at 3 shifts is already in the first row.

How fast does a robotic palletizer pay off on one shift?

In 6 to 8 years with a US$100,000 cell and in 14 to 19 years with a US$250,000 one, before spending a peso on maintenance. Automation Distribution reports maintenance at 3% to 5% of the price per year for cobots (undated guide). Applied to the US$100,000 cell on one shift, payback moves to 83 to 152 months; with the US$175,000 cell, to 14 years or more (Target Robotics calculation with assumptions).

The 40-hour workweek helps little. In 2030, with 2.4 people to cover the same shift, the 69 to 93 months drop to 57 to 78 (same calculation).

What about the 12 to 24 months several suppliers publish? Automation Distribution gives them for cobots on one shift and EVS for multiple shifts (July 15, 2026), without saying which country the labor cost comes from. The calculations that do name the country use the United States: GrabaRobot works with US$43.31 to US$45.45 per hour (August 3, 2026), and Tetakawi puts US$32.12 there against US$5.19 in Mexico (October 2026), from 6 to almost 9 times more. To use a payback published in another country here in Mexico, change the hourly cost first.

Six signs it doesn’t pay off for you yet

What do I do if it doesn’t pay off today?

If the reason is your people’s backs, NOM-036-1-STPS-2018 (DOF, November 23, 2018) requires risk analysis and prevention or control measures (sections 5.1 and 5.2), and when the load exceeds its limits, it accepts team lifts, auxiliary equipment such as carts, hand trucks and pallet jacks, or machinery (section 8.3). The NOM-036 guide breaks it down into steps.

With several small lines, add them up. One stacking point can serve several: Target has built a system serving 6 lines. In the math, the people from each line add up and your operation moves up a row in the table.

When the investment is the obstacle, a cobot lowers it. With Robotiq’s entry price and the same assumptions, 1 shift with 2 people pays for itself in 58 to 79 months, still long, and with the payload and cycle limits that manufacturer publishes. There is more detail in cobot palletizer cost and in cobot vs. industrial robot. Before buying a used palletizer, check spare parts and support.

You can also wait, with a date on the calendar: on January 1, 2028 the workweek drops to 44 hours (DOF, May 1, 2026), and that is the moment to redo the math.

What can tip the math in your favor?

Four line items the table leaves out. It is worth measuring them in your plant before adding them in.

• Workweek. At 3 shifts with 2 people and a US$100,000 cell, the 23 to 31 months drop to 19 to 26 with the 2030 workweek (Target Robotics calculation with assumptions). The calendar is in the 40-hour workweek on the packaging line.
• Turnover and injuries. Every replacement and every disability leave costs money, and that expense comes separately from the month’s payroll.
• Capacity. HowToRobot reports an average 16% increase in output across palletizing projects (March 27, 2026). It only adds up if you sell what you can’t manage to palletize today.
• Taxes. The Plan México immediate deduction, a federal tax incentive for new equipment, helps finance the purchase, and in present value it moves payback by about a month at 3 shifts.

On one shift with 2 people, the line items you can calculate leave payback above 4 years.

Why would a manufacturer publish this table?

A customer asked us for a very expensive 3D camera. We analyzed it with the supplier, showed the customer that a camera 5 to 10 times cheaper solved the application and handed over the report. We worked more to earn less on that project, and this table comes from the same standard.

Before requesting a quote, from us or from anyone, gather four numbers: shifts, people per shift who only stack, fully loaded payroll cost and cases per minute. With them, the payback calculator with Mexican wages places you in a row of the table. If you land in the bottom two, save the quote for later.
