Manufacturing Project Portfolio & Capex worked example

Project Cash Flow at 65% period draw-down rate: a worked example

This worked example runs the project cash flow numbers for a tougher week than the baseline: 65% period draw-down rate instead of the typical 90%. Project the total cash a manufacturing capital project draws across its disbursement schedule.

The inputs for this scenario

  • Disbursement periods: 18 months (held at the documented default)
  • Average monthly outlay: 55,000 $/month (held at the documented default)
  • Period draw-down rate: 65 % (the input this scenario stresses; the baseline uses 90)
  • Upfront mobilization payment: 40,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Cash outflow = periods x monthly outlay x draw-down% + mobilization payment.
  • Total project cash flow cost works out to 683,500 $ at these inputs, and this is the headline figure for the scenario.
  • Project cash flow cost per unit works out to 37,972 $ / piece at these inputs.
  • Variable project cash flow cost works out to 643,500 $ at these inputs.
  • Fixed project cash flow adder works out to 40,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where period draw-down rate sits at 90% and the headline result is 931,000 $, this scenario comes in 26.58% below the baseline at 683,500 $.
  • Use it during capex authorization and again at each gate review to refresh the cash schedule once vendor payment terms and milestone draws are confirmed. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total project cash flow cost: 683,500 $ (headline result)
  • Project cash flow cost per unit: 37,972 $ / piece
  • Variable project cash flow cost: 643,500 $
  • Fixed project cash flow adder: 40,000 $
