Finance Calculators
Mortgage Calculator
A mortgage payment spreads the amount borrowed over the term at the agreed rate: principal and interest every month, with interest weighted towards the early years. Enter the price, the down payment, the term and the rate, and the result shows the monthly payment, the total interest, the payoff date and what extra payments save.
Calculator
Formula Used
Monthly Payment = P × [r(1+r)^n] ÷ [(1+r)^n − 1], where P = loan amount (home price minus down payment), r = monthly interest rate, n = total months.
About This Calculator
What It Does
Calculate your monthly mortgage payment based on the home price, your down payment, the loan term, and the interest rate. See the loan amount, total interest, and total repayment over the life of the loan. This calculator covers principal and interest only — it does not include property taxes, homeowners insurance, HOA fees, or mortgage insurance (PMI). Use it to understand how your down payment size, loan term, and interest rate interact. A larger down payment means a smaller loan and less interest. A shorter term means higher payments but dramatically less total interest.
Worked Example
Example 1 — Standard: A 180,000€ home with 36,000€ down (20%) leaves a 144,000€ loan. Over 25 years at 3.5%: monthly payment ≈ 721€. Total interest ≈ 72,200€. Example 2 — Shorter term: Same 144,000€ loan at 3.5% but over 15 years: monthly payment ≈ 1,029€. Total interest ≈ 41,300€. Saving 30,900€ in interest. Example 3 — Larger down payment: A 180,000€ home with 54,000€ down (30%) leaves a 126,000€ loan at 3.5% over 25 years: monthly payment ≈ 631€. Total interest ≈ 63,200€.
Real-World Usage
Home buyers use this to determine their price range before starting their search. Compare fixed and variable rate scenarios. See how a 15-year vs 30-year term fits your budget. Real estate agents use it to illustrate affordability. Refinancing decisions: compare current loan terms against a new offer. Use it to plan — a larger down payment reduces not just your monthly payment but also the total interest by tens of thousands.
Local Context
Italian mortgages typically require 20% down. First-home buyers under 36 benefit from reduced taxes (under-36 scheme). Fixed-rate mortgages have become common since 2023. Mortgage portability (surroga) to another bank is free by law. Typical terms are 20-30 years. Notary and processing fees vary by bank. The monthly payment should not exceed 35% of net income.
Variable-Rate Mortgages: How the Rate Is Reset and What to Compare
An adjustable or variable-rate mortgage starts below the going fixed rate, but the interest rate does not stay put: at each reset it is recalculated from a reference index plus a fixed margin. The contract sets the reset periodicity (monthly, quarterly, semi-annual or annual), the index and the margin. Depending on the deal, a rise in the index shows up as a higher monthly payment, a longer loan term, or both; many contracts also put a cap on how far the rate can rise, sometimes with a floor below which it cannot fall. Before signing, compare the APR — fees and required insurance included — rather than the first-year nominal rate alone, and read the reset formula, the periodicity, the index, the margin, the cap and the floor, and what happens to the payment when the rate rises (payment, term, or both). This calculator assumes a fixed rate: for a variable-rate loan, enter the rate from the highest scenario you would have to absorb.
Sources and Methodology
Mortgage estimates use standard amortization formulas plus configured country-specific assumptions for taxes, fees, insurance, or purchase costs where available. Check final affordability, fees, and eligibility with lenders and official housing, tax, or central bank sources for your jurisdiction. For France, the variable-rate rules described above are taken from the French Code de la consommation (articles L313-25 and L313-46) and from the quarterly taux d'usure thresholds published by the Banque de France.

Frequently Asked Questions
How much down payment do I need for an Italian mortgage?
Italian banks typically require 20% down payment for primary residences. Non-residents may need up to 30% or more. The mortgage registry tax (imposta di bollo) applies.
What is mortgage surrogation (surroga) in Italy?
Surrogation lets you transfer your mortgage to another bank without fees. The new bank pays off your old mortgage and you benefit from better terms. It is free by law.
Is a fixed or variable rate better in Italy?
Fixed rates offer payment certainty; variable rates (linked to EURIBOR) can be cheaper short-term. Most Italian borrowers choose fixed rates when they are low.
