Mortgage simulation: monthly payment, fees and total cost

Work out in seconds what a property purchase would really cost you: the monthly payment, but also conveyancing fees, insurance, bank charges and the total cost of the loan.

Don't know a figure yet? Answer “I don't know”: the calculator then uses the most common market value and tells you which one.

🏦 Your project

The only two figures that really matter: what the property costs, and what you can put in yourself.

Property price

0 € — the price shown in the listing, excluding conveyancing fees.

Deposit

The money you already have (savings, a gift, the sale of a property). Banks like it to cover at least the conveyancing fees.

Type of home

This changes the conveyancing fees a great deal: around 8 % of the price for an existing home, against 2 to 3 % for a new one.

County purchase tax

We use 6.32 % — this is the rate applied by the great majority of counties since 2025. The gap with 5.81 % comes to about €1,275 on a €250,000 property.

📉 Loan terms

Haven't seen a bank yet? Leave “I don't know” everywhere: the calculator applies the most common market values and tells you which ones.

Loan term : 20 years

The longer the term, the lower the monthly payment — but the more the loan costs overall.

Annual interest rate

We assume 3.18 % — Banque de France — average home loan rate for August 2026, adjusted to the term you chose.

Borrower's insurance

Compulsory: it repays the bank in the event of death or disability. Its price depends mainly on your age and health. We assume 0.34 % per year of the amount borrowed, i.e. 0.00 € per month.

Security required by the bank

The security the bank takes in case the loan is not repaid. You are charged for it up front.We assume a guarantee company, by far the most common today.

Bank arrangement fee

What the bank charges to put your file together. Often negotiable, sometimes waived.We use €1,000, a common figure.

Broker's fee

Only fill this in if you go through a broker. Leave 0 if you approach the banks yourself.

👛 Your situation (optional)

Fill in these two amounts to find out whether your plan clears the 35 % debt-to-income bar, and how high a price you could go to.

Household net monthly income

What actually lands in the account each month, for all borrowers together: net salaries, pensions, rent received.

Existing loan repayments

Your other current loans: car, home improvements, student loan. Your present rent does not count, since it will stop.

💶 Enter the property price above to get your monthly payment, the total cost of the loan and the notary fees.

A loan commits you and must be repaid. Check that you can afford the repayments before you commit.
