KPIs in manufacturing are quantifiable metrics that offer insight into business performance. KPI stands for Key Performance Indicator and they do just as the name suggests - they indicate successful performance.
One commonly-used manufacturing KPI is “overall equipment efficiency”(OEE) which is measured by calculating the factory’s performance, availability, and quality. While an effective measure of performance, especially at the factory floor, machine-specific level, OEE should ideally be used alongside other KPIs to gain greater clarity on performance from multiple angles. Manufacturing businesses can, and should, choose several KPIs to focus on in order to help guide decision-making.
KPIs are important for manufacturers because they are defined, measurable metrics that help businesses focus on what’s most important, so they can track, analyze, and optimize performance over a period of time.
KPIs let manufacturers know whether they are on course for success, if they are growing, and where issues may be present within their businesses. Having a KPI dashboard readily available can make company goals and priorities stay in focus and ensure the organization is moving forward as a whole.
Below we cover over 50 manufacturing KPIs, providing both their definitions as well as how to calculate each of them. There are hundreds of manufacturing metrics in existence, but we have created a simple way to browse through the most important production KPIs. You can skip to any manufacturing metric by selecting it in the table below.
You can also jump directly to the "Manufacturing KPI Dashboards, Reports, and Templates" section. Manufacturing dashboards are important for visibility on various levels of the organization, including shop managers, operators on the shop floor, as well as corporate. Within that section, we show off some of the simple, useful production dashboards available from MachineMetrics.
Asset Turnover is the value of sales or revenues generated. It measures the efficiency with which a manufacturer uses its equipment and other assets to drive revenue. Companies with a high turnover ratio are more efficient than those with a lower turnover.
Asset Turnover = Net Sales / Average Total Assets
Asset Utilization is the total revenue earned for every dollar of assets owned. It measures how well you are using your installed capacity.
Asset Utilization = (Actual Output / Maximum Capacity) *100
Availability is the run time compared to planned production time. It is similar to overall availability, but uses planned production time, rather than total calendar time.
Availability = Uptime / (Uptime + Downtime)
Avoided Costs are expenses that will not be incurred by the manufacturers if the associated activity is no longer done. For example, a manufacturer may discontinue a product line, which means they will have a variety of avoided costs in the form of labor and equipment usage.
Avoided Cost = Sum of expenses avoided from foregoing a particular activity
Capacity Utilization is the rate at which potential output levels are being met or used. It essentially tracks how much of a manufacturer’s production capacity is currently being utilized.
Capacity Utilization = (Actual output/Maximum possible output)*100

Overall Equipment Effectiveness provides a means to measure the percentage of planned manufacturing time that is productive. OEE is calculated by multiplying availability, performance and quality and is represented by a percentage and only considers scheduled time. An OEE of 100% would mean that a manufacturer producing only good parts, as fast as possible, with no stop time.
Overall Equipment Effectiveness = Availability x Performance x Quality
Overall Operating Efficiency is similar to OEE except it takes unscheduled time into account, looking at Total Operations Time as the maximum.
Overall Operating Efficiency (OOE) = Availability (where Availability = Actual Production Time / Operating Time) x Performance x Quality
