How this calculator works

Maximum HOA = income x target housing ratio - mortgage - property tax - insurance. The entered HOA is compared with that remaining room.
Housing budget = monthly income x target ratio. Maximum HOA = budget - other housing costs. Housing ratio = total housing cost / income.

Inputs explained

Rates and prices

Use your current utility bill, HOA statement, tax notice, quote, or lender estimate where possible.

Usage assumptions

Enter expected daily, monthly, or annual usage rather than relying on national averages.

Planning period

Use a realistic ownership or analysis period for ROI and comparison calculators.

Understanding your results

Results are planning estimates. Local tariffs, taxes, weather, building condition, loan terms, and contractor quotes can materially change the real outcome.

Example scenarios

Practical scenario

With $8,000 monthly income and a 30% housing target, a $1,850 mortgage, $450 tax, and $160 insurance leaves about $ -60 before HOA.

Key Features

Tips & Best Practices

  • Use all-in rates when bills separate supply, delivery, taxes, and fees.
  • Run conservative and optimistic cases before making a purchase decision.
  • Keep quote-specific rebates, maintenance, and financing terms separate when they matter.

Frequently Asked Questions

Should I include utilities?
Include utilities in other monthly housing costs if your affordability target is meant to cover them.
Does this follow lender underwriting rules?
No. It is a household budget screen, not a loan approval model.
What if HOA dues can increase?
Run a higher HOA scenario to test future assessments or dues increases.
