Introduction à l'outil

Vue d'ensemble de l'outil

Your true monthly housing cost is more than the amortized loan payment. Lenders usually bundle property tax and hazard insurance into escrow (the "T" and "I" in PITI), and many homes add HOA dues on top. This calculator combines all four figures and also shows your down-payment percentage, loan-to-value, and a private-mortgage-insurance warning for US buyers with less than 20% down. All inputs are local to the browser.

Questions fréquentes

What is PITI?+

Principal, Interest, Taxes, and Insurance — the four components of a typical US escrowed mortgage payment. PITI + HOA is usually what your lender and budgeting tools care about.

Does it calculate PMI?+

Not directly. PMI rates depend on lender, credit score, and loan program. We flag when your down payment is below 20%, which is the usual trigger for PMI on conforming US mortgages.

What about ARM or interest-only mortgages?+

The tool models a conventional fixed-rate, fully-amortizing loan. Adjustable-rate mortgages have rate changes; interest-only mortgages defer principal — neither is represented here.

Can I use this outside the US?+

Yes — the math works for any fixed-rate mortgage. Some local concepts (PMI in particular) are US-specific, so treat that warning as optional information.
