Make the result useful
Property-cash-runway planning
Available cash is property cash that can actually cover operating obligations.
Monthly costs are the recurring obligations you choose to include.
Runway is a static snapshot before future rent, repairs, or financing changes.
A longer runway is not a substitute for accurate billing and reserve planning.
The assumptions that move this result
Available cash
Accessible property cash.
Monthly costs
Recurring modeled obligations.
Coverage period
Months implied by the division.
Cash restrictions
Amounts that may not be available.
Calculation lens
cash runway months = available cash ÷ monthly costs
Use the output as a documented scenario result, not a guarantee.
Read the number in context

Ignores incoming rent, variable expenses, and restricted funds.
Before you act
Confirm accessible cash.
