Free monthly housing tool
PITI calculator
Estimate principal, interest, property taxes, and homeowners insurance, then show mortgage insurance and HOA dues separately.
The short answer
Last updated: July 2026
PITI equals monthly principal and interest plus one-twelfth of annual property taxes and one-twelfth of annual homeowners insurance. Mortgage insurance and HOA dues are not part of the strict four-letter acronym, so this calculator reports them separately before showing a broader estimated monthly housing total. Taxes, insurance, and escrow payments can change.

Estimate based on your inputs. Not a promise of results.
Taxes, insurance, escrow, and association charges can change. This estimate excludes maintenance, utilities, assessments, flood or specialty coverage, and lender eligibility decisions.
How it works
How this tool works.
A quoted principal-and-interest payment can understate the cash required each month. PITI adds taxes and homeowners insurance, but even PITI may omit mortgage insurance, HOA dues, flood insurance, assessments, utilities, and maintenance.
Use current tax and insurance evidence where available and stress increases instead of treating today’s estimate as fixed.
Make the result useful
PITI is a floor for planning, not a complete ownership budget
The principal-and-interest calculation uses the loan amount, rate, and amortization term. Taxes and insurance are property costs whether paid directly or collected through escrow.
For an owner or landlord budget, add every item outside the acronym: mortgage insurance, HOA or condo dues, flood or specialty coverage, utilities, maintenance, capital reserves, management, and other property-specific obligations.
