How do you calculate automation payback period?

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

What is a good payback period for power electronics automation?

Most electronics plants approve automation under a 2-year payback and scrutinize anything over 3 years. The 1.61-year result here is well inside the typical hurdle, leaving margin for slower ramp-up.

Why subtract support cost from savings?

Robots, feeders, and vision systems need maintenance, spares, and reprogramming for new board revisions. Ignoring the $2,500/yr support here would understate payback and overstate the true return.

Payback period vs ROI, which should I use?

Payback answers how fast you recover cash; ROI and NPV answer how much value the project creates over its life. Use payback to screen quickly, then run NPV on the survivors, especially for cells with a 7-10 year service life.

Does a short payback always mean I should automate?

Not alone. A 1.61-year payback is attractive, but also weigh product lifecycle, changeover flexibility, floor space, and whether volumes will hold long enough to realize the five-year net value of $52,500.

How is five-year net value calculated here?

It multiplies net annual savings by five and subtracts the investment: $15,500 x 5 - $25,000 = $52,500, giving a rough view of cumulative benefit over a typical planning horizon.

Power Electronics, Motors & Drives calculator

Power Electronics Automation Payback Calculator

Automation payback period tells a power electronics or drives plant how many years an automated cell, robotic solder station, or automated coil-winder takes to pay back its capital cost out of the net savings it generates. Continuous-improvement engineers and plant managers use it to prioritize capex when several automation projects compete for the same budget. It matters because power electronics automation often carries high upfront cost, vision-guided placement, selective soldering, in-circuit test handling, and a payback longer than the product's production life destroys the business case. This calculator strips the pitch down to the number that gates most approvals.

What this calculator does

Estimate simple payback for automation used in inverter, drive, power module, motor, or converter production from investment, annual savings, and support cost.
Use it when screening automation for dispensing, screwdriving, winding, soldering, inspection, test handling, burn-in loading, or material movement.
It computes the simple payback period in years by dividing the automation investment by the net annual savings after subtracting ongoing support cost.

Formula used

Net annual automation savings = annual automation savings - annual automation support cost
Power electronics automation payback period = automation investment ÷ net annual automation savings
Five-year ROI = five-year net value ÷ investment × 100

Inputs explained

Automation cell capital investment:
Annual labor and scrap savings from automation:
Annual robot maintenance and programming cost:

How to use the result

Use it during capex screening when comparing automation proposals for placement, soldering, winding, or test handling, or to sanity-check a vendor's ROI claim.
Simple payback ignores the time value of money, ramp-up losses, and equipment residual value, so treat it as a first-pass filter rather than a full NPV or IRR analysis.

Current U.S. benchmarks

The producer price index for copper and brass mill shapes stands at 542.853 (BLS, Jul 2026), up 52.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,543 per tonne (IMF via FRED, Jul 2026).
The U.S. has 11,261 computer and electronic products establishments employing about 815,443 workers (Census County Business Patterns, 2023).
