Can schedule attainment go above 100%?

Yes, when more good units are completed than the schedule called for. That is real output, but check whether it came from a smaller mix, overtime or work borrowed from the next period.

How is attainment different from on-time delivery?

Attainment compares good units with the scheduled quantity inside a period. On-time delivery asks whether each order shipped by its promised date, so an order filled early can help attainment and still count as off plan elsewhere.

Which units count as completed?

Good, shippable units finished in the period, counted at the same point the plan is stated: end of line, pack or ship. Keep the same point every period or the trend lies.

What target should operations set?

Start from your own best sustained result, then nudge it up a point at a time. A target the line never hits stops being a signal, and a target it always beats stops driving action.

Lean Manufacturing & Operations calculator

Schedule Attainment Rate Calculator

Measure how much of the published schedule was completed and how far the result sits from your target. You need actual and planned counts and the target percentage.

What this calculator does

Schedule attainment against the plan and the target, with the units needed to close the gap.

Formula used

Schedule attainment = actual units completed ÷ planned units × 100
Gap to target = target attainment − schedule attainment (positive when below target)
Target units = planned units × target attainment ÷ 100
Units below target = MAX(0, target units − actual units completed)

Inputs explained

Actual Units Completed: Good units finished in the period, from the shift record.
Planned Units: Units the published schedule called for in the same period.
Target Attainment: Attainment goal from the operating plan or budget.

How to use the result

Best suited to daily shift scorecard, weekly plan versus actual review, sizing a recovery plan.
Attainment counts volume only: building the wrong mix can still hit the number.

Current U.S. benchmarks

U.S. manufacturing runs at 75.7% of capacity (Federal Reserve, Aug 2026). New factory orders are up 8.5% year over year (Census).
