Quick guide

How to use this calculator

  1. Enter amounts from the same property scenario and use consistent periods and units.
  2. Use visitor-entered rates and allowances from your own documents rather than assuming a local rule.
  3. Review the component results and the calculator-specific decision boundary before acting.

Calculation method

Calculation method

Monthly net cash flow = sales and other inflows − uses; cumulative funding exposure is the absolute value of the most negative cumulative balance.

Entered fixed decimals remain exact through rational arithmetic. Planar distance outputs that require square roots use bounded numerical evaluation. Values round only for display, and unsupported or undefined states return an explicit message.

Worked example

Worked example

Three months with uses before sales expose the peak cumulative amount even when the project later returns to surplus.

Monthly net cash flow = sales and other inflows − uses; cumulative funding exposure is the absolute value of the most negative cumulative balance.

Supported inputs

Precision and limits

International scope

No currency, market price, interest rate, tax, tenancy rule, planning code, lender policy, or measurement definition is supplied automatically.

Scenario, not a decision

Results are arithmetic scenarios from visitor-entered values—not an appraisal, loan approval, legal interpretation, planning determination, forecast, or professional recommendation.

Precision and privacy

Inputs accept bounded plain decimals and remain in this browser. The engine prevents invalid denominators and misleading non-finite results.

Calculator-specific boundary

Rows are chronological month-end cash flows. Financing availability, tax, draw conditions and delay are not inferred.
