Jak działa ten kalkulator?
Monthly PITI = P&I + monthly property tax + monthly insurance (+ PMI if LTV > 80%). P&I is computed with the amortisation formula L·r(1+r)^n/[(1+r)^n−1]. Tax and insurance figures in this calculator are editable US estimates — replace them with your local actuals.

How this is calculated
The Principal and Interest component is calculated using the standard amortisation formula: P&I = L × [r(1+r)^n] / [(1+r)^n − 1], where L is the loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100) and n is the total number of monthly payments. This assumes a fixed-rate mortgage with equal monthly payments throughout the term.
Property tax and homeowners insurance are added at their monthly fraction (annual amount ÷ 12). These vary widely by location and coverage: US property tax averages roughly 1–2% of home value per year, and homeowners insurance typically runs $800–$2,000/year for a median-priced home. The pre-filled figures are editable estimates — check your local tax authority and insurance quote for accurate numbers.
Private Mortgage Insurance (PMI) is required by most US lenders when the loan-to-value ratio exceeds 80% (down payment below 20%). It protects the lender, not the borrower. Once the LTV drops to 80% through payments or appreciation, you can typically request PMI cancellation. The PMI rate defaults to 0.5% annually but varies from about 0.2% to 1.5% depending on credit score and loan type.
Najczęściej zadawane pytania
PITI stands for Principal, Interest, Taxes and Insurance — the four main components of a monthly mortgage payment. Lenders use the total PITI figure to assess affordability, typically requiring it to be no more than 28–31% of gross monthly income.
For conventional loans in the US, the Homeowners Protection Act requires lenders to cancel PMI automatically when your LTV reaches 78%, and you can request cancellation at 80%. This happens either through your regular payments reducing the principal, a home appraisal showing value appreciation, or a combination of both.
The pre-filled values are broad US averages for illustration — actual property taxes depend on your state, county and municipality, and homeowners insurance premiums depend on location, home type, coverage level and insurer. Always use your actual tax bill and insurance quote for precise budgeting.
