FormulaCash at current = v.potential_rent*(1-v.current_vacancy/100)-v.operating-v.debt_service-v.reserve ; Maximum vacancy = 100*(1-(v.operating+v.debt_service+v.reserve)/v.potential_rent) ; Vacancy headroom = 100*(1-(v.operating+v.debt_service+v.reserve)/v.potential_rent)-v.current_vacancy

How to use this tool

  1. Enter your own assumptions using a consistent currency and period.
  2. Review the scenario outputs and compare alternative inputs.
  3. Check the stated model limits before using the result in an operating plan.

Try this example

{
  "potential_rent": 100000,
  "operating": 30000,
  "debt_service": 40000,
  "reserve": 5000,
  "current_vacancy": 10
}

Accuracy and scope

Deterministic planning scenario; inputs are assumptions, not forecasts. Excludes taxes, financing, legal requirements and costs not explicitly entered. Source explains the underlying planning framework; this specific scenario arithmetic is original.
