How this estimate works

Monthly charges (society rate × size, fixed charges, utilities) are combined with yearly property tax and repairs, plus a reserve for each big replacement equal to its cost divided by its life. Yearly costs rise at your inflation assumption.

Formula

  • Monthly recurring = society rate × sq ft + fixed + utilities
  • Yearly reserve = Σ (replacement cost ÷ life in years)
  • Year t budget = yearly budget × (1 + inflation)^(t−1)

Limitations

  • Reserve items and lifespans are editable examples, not official rules.
  • Society charges and taxes vary by society and municipality.

Data used
