Choose how deeply to explain Project Peak Funding Requirement
Project Peak Funding Requirement: Estimate peak working-capital funding from monthly cost, collection lag and customer advances.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Project Peak Funding Requirement to answer this question: estimate peak working-capital funding from monthly cost, collection lag and customer advances? Enter Average monthly project cash cost, Collection lag months, Customer advance available, and 1 other input; the calculator shows Peak funding including contingency. Try changing one number and watch what happens to Peak funding including contingency. The answer tells you Peak funding including contingency.
Age 15Explain it to a 15-year-oldConnect it to the formula
A detailed monthly cash curve is preferable when mobilisation, retention, milestones or procurement are uneven. The rule is Peak funding ≈ monthly cash cost × collection lag − available advance. Its input values are Average monthly project cash cost, Collection lag months, Customer advance available, Contingency on funding need (%), and the main result is Peak funding including contingency. Try changing one number and watch what happens to Peak funding including contingency.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Peak funding ≈ monthly cash cost × collection lag − available advance, evaluated from Average monthly project cash cost, Collection lag months, Customer advance available, Contingency on funding need (%) to produce Peak funding including contingency. A detailed monthly cash curve is preferable when mobilisation, retention, milestones or procurement are uneven. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Estimate peak working-capital funding from monthly cost, collection lag and customer advances.
Why the business model works
A detailed monthly cash curve is preferable when mobilisation, retention, milestones or procurement are uneven.
Inputs and operating assumptions
This model uses Average monthly project cash cost, Collection lag months, Customer advance available, Contingency on funding need. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Peak funding ≈ monthly cash cost × collection lag − available advance
What the calculator produces
The primary output is Peak funding including contingency; it also exposes Base working-capital requirement, Funding contingency. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
