ERP & MRP Planning calculator
Schedule Attainment Calculator
Schedule attainment measures how much of your planned production schedule you actually completed on time, expressed as a percentage of total scheduled units. Production planners, MRP schedulers, and plant managers track it to see whether the master production schedule (MPS) is realistic and whether the floor is executing to it. Unlike a simple output count, attainment ties completion to the dates and quantities the plan committed to, so it exposes broken promises to downstream cells and customers before they surface as late shipments. A consistently low number usually means the schedule is over-loaded, material is short, or changeovers are stealing capacity.
What this calculator does
- Calculate the share of scheduled orders or units completed as planned.
- a supervisor needs to measure completed schedule versus the committed plan
- It computes the percentage of scheduled units finished on time against the total units the schedule called for, plus the point gap to your attainment target.
Formula used
- Schedule attainment = scheduled units completed on time ÷ total scheduled units × 100
Inputs explained
- Scheduled units completed on time:
- Total scheduled units:
- Target schedule attainment:
How to use the result
- Use it at the end of each shift, day, or planning bucket to grade schedule execution and feed the next MRP run.
- It only counts units completed on time against the plan — it says nothing about whether the plan itself was correct, so a low target can make a bad schedule look 'attained.'
Current U.S. benchmarks
- Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
- U.S. manufacturing runs at 75.6% of capacity (Federal Reserve, May 2026). New factory orders are up 2.3% year over year (Census).
Common questions
- How do you calculate schedule attainment? Divide the scheduled units completed on time by the total scheduled units, then multiply by 100. With 1,840 units completed on time out of 2,000 scheduled, attainment is 1,840 ÷ 2,000 × 100 = 92%.
- What is a good schedule attainment percentage? World-class job shops and discrete plants aim for 95% or higher; 85-95% is typical and workable. The 92% in our example is solid but sits 3 points short of a 95% target, so there is real recoverable capacity.
- What is the difference between schedule attainment and OEE? OEE measures equipment effectiveness (availability, performance, quality) on a machine. Schedule attainment measures whether you hit the planned quantities on time across the schedule. You can run high OEE on the wrong jobs and still miss attainment.
- Why is my schedule attainment low even though output is high? High output on unscheduled or early jobs doesn't count. Attainment credits only units finished on time against what the plan asked for, so cherry-picking easy work or running ahead on low-priority orders drags the number down.
- How is the gap to target used? The point gap (here 3 points) is the shortfall against your target. Multiply it by total scheduled units to size the recovery: 3% of 2,000 is 60 units to claw back next period.
