How do you calculate rough-cut capacity utilization?

Divide the required MPS load hours by the available rough-cut capacity hours, then multiply by 100. With 3,800 load hours against 4,400 available hours, utilization is 86.36%.

What is a good rough-cut utilization target?

Most schedulers target 80-90% on a critical resource to leave headroom for variability and rework. In the example a target of 85% against an actual 86.36% leaves a gap of -1.36 points, meaning the schedule slightly overloads the resource.

What does a negative gap to target mean?

A negative gap means actual utilization exceeds your target — the resource is loaded harder than planned. The -1.36 points here signals you should offload work, add overtime, or reschedule before releasing the MPS.

What is the difference between RCCP and CRP?

RCCP checks the master schedule against a few critical resources using aggregate bill-of-resource factors. CRP (capacity requirements planning) runs after MRP and checks every work center using detailed routings and lot sizing, so it is far more granular but much later in the cycle.

Which resource should I run RCCP against?

Pick the constraint — the work center, labor pool, or supplier with the least slack relative to demand. Running RCCP on a non-bottleneck wastes the check, since a feasible result there says nothing about the resource that actually limits throughput.

Can utilization be over 100%?

Yes. If required load hours exceed available hours the formula returns more than 100%, which means the MPS is infeasible as written and must be re-leveled, expedited with overtime, or partially deferred.

ERP & MRP Planning calculator

Rough Cut Capacity Planning Calculator

Rough-cut capacity planning (RCCP) is the validation step master schedulers run after building the MPS but before committing detailed material and shop-floor plans. It compares the total load hours a master production schedule will impose on a critical resource against the rough-cut capacity that resource can realistically supply, expressed as a utilization percentage. Planners in ERP and MRP environments use it to catch infeasible schedules early — when the MPS would push a bottleneck work center past its limit — without the cost of running full CRP. The output tells you whether the schedule is achievable and by how many points you are above or below your target loading.

What this calculator does

Calculate rough-cut capacity utilization from required master-schedule hours and available work-center hours.
a master scheduler needs to see whether MPS demand overloads key work centers
It computes rough-cut capacity utilization (required MPS load hours divided by available rough-cut hours) and the point gap between that utilization and your target.

Formula used

Rough-cut utilization = required MPS load hours ÷ available rough-cut capacity hours × 100
Gap to target = target rough-cut utilization - actual rough-cut utilization

Inputs explained

Required MPS load hours: Use master-schedule demand multiplied by rough-cut bills of capacity or routing standards.
Available rough-cut capacity hours: Use available labor or machine hours after holidays, shifts, and planned downtime.
Target rough-cut utilization: Use the planning target that leaves room for variation, maintenance, and schedule changes.

How to use the result

Use it during MPS sign-off or a sales-and-operations planning review to confirm a master schedule fits a critical work center before releasing it to MRP.
RCCP uses aggregate bill-of-resource load factors, not routed operation data, so it can miss short-interval overloads and assumes the chosen resource is the true constraint.

Current U.S. benchmarks

As of May 2026, U.S. manufacturing runs at 75.6% of capacity (Federal Reserve via FRED), up 0.2 points from a year earlier. Enter your own plant's utilization; the national figure is a reference point for how loaded the industry is.
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).
