How do you calculate capex approval workload?

Divide requests by the throughput rate for base hours, then multiply by (1 + allowance). 120 requests at 12 per minute give 10 base hours; a 10% allowance makes it 11 hours required.

What does the approval throughput rate mean here?

It's how many standard requests a reviewer clears per minute at sustained pace. At 12 per minute the team processes 720 an hour of routine items before allowances for delays.

Why add a delay allowance to approvals?

Approvals stall on missing data, clarifications, and committee scheduling. The 10% allowance adds an hour per ten productive hours to reflect that real friction.

What is a realistic approval allowance?

Routine, well-documented requests run 10-20%; first-time or cross-functional capex can need 30%+. If 11 required hours keeps under-running reality, your friction is higher than 10%.

How do I clear a capex backlog faster?

Standardize request templates to raise throughput, and cut delay allowance by pre-collecting justification and benefit data. Both shrink the required hours directly.

Base hours vs required hours — which do I staff to?

Always staff to required hours (11 here). Base hours (10) ignore the clarification and committee time that real approvals always incur.

Manufacturing Project Portfolio & Capex calculator

Capex Approval Workload Calculator

Capex Approval Workload estimates the labor hours your finance and governance team needs to move a batch of capital requests through review, documentation, and signoff. PMO leads, capex controllers, and finance managers use it to size approval capacity during budget season and avoid the bottleneck that stalls otherwise-funded projects. It matters because approval throughput, not just project merit, often gates how fast capital deploys — and the delay allowance captures the back-and-forth, clarifications, and committee waits that raw rates miss. The output is the staffed hours to clear the queue.

What this calculator does

Estimate capex approval workload for manufacturing project portfolio and capex using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.
Use it when capex approval workload in manufacturing project portfolio and capex is changing rate or allowance and you want to see the impact.
It divides the number of capex requests by the approval throughput rate, then applies an allowance for clarifications and committee delays to yield required processing hours.

Formula used

Base capex approval workload time = capex approval workload workload ÷ capex approval workload completion rate
Required capex approval workload time = base capex approval workload time × allowance factor

Inputs explained

Capex requests to process:
Approval throughput rate:
Setup, handling, and delay allowance:

How to use the result

Use it before a budget cycle or capital-call window to confirm the approval team can clear the request volume on time.
It assumes requests are roughly uniform in complexity; a single mega-project review can consume more time than the rate implies, skewing the estimate.
