How do you calculate schedule attainment rate?

Divide actual units completed by the planned (scheduled) units and multiply by 100. With 185 actual against 200 planned, that's (185 / 200) x 100 = 92.5%.

What is a good schedule attainment rate?

World-class plants run 95% or higher consistently; 90-95% is solid for most discrete manufacturers. At 92.5% against a 95% target you're 2.5 points short, which is recoverable but worth a root-cause review.

What's the difference between schedule attainment and OEE?

OEE measures how well equipment ran (availability, performance, quality) while attainment measures whether you hit the scheduled volume. You can have 90% OEE and still miss attainment if you ran the wrong product or had a short order.

Why is my attainment below 100% even when machines ran well?

Common causes are material shortages, changeover overruns, downstream blockages, or building ahead on a different SKU. The 15-unit shortfall in the example points to something that ate planned capacity, not necessarily slow machines.

Should attainment ever exceed 100%?

It can if you overbuild, but capping the count at scheduled volume is usually better practice — running extra units off-plan ties up materials and floor space and distorts the metric.

How is attainment different from production plan variance?

Attainment gives a percentage of plan achieved; plan variance gives the unit gap, optionally net of authorized adjustments. Use attainment for trending and variance for accountability on a specific shortfall.

Lean Manufacturing & Operations calculator

Schedule Attainment Rate Calculator

Schedule attainment rate is the percentage of your scheduled production volume you actually completed in a given period, calculated as actual units divided by planned units. Production supervisors, planners, and plant managers track it shift-by-shift to see whether the floor is delivering against the master schedule, not just running fast. It matters because a line can post high OEE while still missing the build plan if it ran the wrong product mix or fell short on volume. Unlike efficiency metrics, attainment ties directly to customer commitments and downstream stocking, so it's the number S&OP and order fulfillment teams trust most.

What this calculator does

Calculate schedule attainment as a percentage by comparing actual completed units to the planned production schedule for a given period.
Use this calculator to measure how reliably your production meets the planned schedule. Low attainment signals disruptions, planning errors, or capacity shortfalls that need investigation.
It computes the percentage of scheduled units actually completed and the gap in points to your target attainment rate.

Formula used

Schedule Attainment = (Actual / Planned) x 100

Inputs explained

How to use the result

Use it at the close of every shift, day, or week to grade execution against the published production schedule and to trigger recovery actions when you fall short.
Attainment counts volume against plan but ignores quality, mix accuracy, and whether the right SKUs were built — a unit made early or to the wrong order can still inflate the rate.

Current U.S. benchmarks

U.S. manufacturing runs at 75.6% of capacity (Federal Reserve, May 2026). New factory orders are up 2.3% year over year (Census).
