France Mortgage Calculator: Estimate Your Monthly Mortgage Payment

Use the free France Mortgage Calculator to estimate payments, interest, LTV, borrower insurance, property costs and an amortisation schedule.

A France Mortgage Calculator helps buyers estimate the financial commitment involved in purchasing a house or apartment in France. It calculates the proposed loan, monthly principal and interest, recurring property costs, total interest and expected payoff date.

French property finance includes expenses that do not form part of principal and interest. Assurance Emprunteur may add a monthly borrowing cost, while Taxe Foncière and Assurance Habitation are ownership expenses. Buyers must also prepare for acquisition and financing costs such as Frais de Notaire and Frais de Garantie.

This French mortgage calculator is useful for residents, international buyers and people comparing a prêt immobilier for an existing home, a new property or a VEFA, meaning a sale before construction is completed. Its results are estimates, not a loan offer or personalised advice. Approval and final costs depend on the lender, borrower profile, property, insurer, transaction and current French rules.

How the France Mortgage Calculator Works

Begin with the prix du bien, or home price, and your apport personnel, the contribution paid from your own funds. Subtracting the contribution from the price gives the proposed loan amount. The calculator then uses the annual nominal interest rate and the durée du prêt, or loan term, to estimate a regular principal-and-interest payment.

For a standard prêt amortissable, each mensualité contains interest and principal. Interest is initially calculated on a larger outstanding balance, so it represents a greater share of early payments. As principal falls, the interest portion normally declines and the principal portion increases.

The calculator can then add estimated monthly Taxe Foncière and Assurance Habitation. Borrower insurance is shown as a separate mortgage-related cost where applicable, rather than being mixed into principal and interest. Upfront inputs can include apport personnel, Frais de Notaire, initial insurance costs and, where provided, guarantee fees.

The five report areas help users move from a single monthly figure to a fuller financing view:

1. Mortgage Summary: Loan, monthly payment, total interest, total paid and payoff date.
2. Monthly Cost Breakdown: Principal and interest, estimated tax, home insurance and borrower insurance.
3. Cash Needed: Contribution and entered purchase or financing costs.
4. Payoff Preparation: Additional repayment, estimated savings, earlier payoff and LTV.
5. Amortisation Preview: Payment, principal, interest and remaining balance by month.

Use the calculator to compare scenarios, then check the lender’s offer and tableau d’amortissement before committing.

Illustrative example

Assume a €450,000 home, a €90,000 apport personnel and a €360,000 loan over 25 years. At an illustrative fixed nominal rate of 3.5%, the estimated monthly principal and interest is approximately €1,802.24. This is an example rate, not a statement of current French mortgage rates.

If the rate stayed unchanged for 300 monthly payments, total principal and interest would be about €540,673.46, including approximately €180,673.46 of interest. An estimated property-tax rate of 0.2% of price would add €75 a month, while estimated home insurance at 0.3% would add €112.50. Under the calculator’s defined formula, the monthly mortgage and ownership estimate would be about €1,989.74 before borrower insurance.

Borrower insurance estimated at 0.3% of the original loan would add €90 a month. The resulting illustrative monthly outflow would be about €2,079.74. Actual Taxe Foncière and insurance premiums are not calculated from purchase price in this simple way by the authorities or insurers, so replace these estimates with quotations and official notices.

Required Inputs for a France Home Loan Calculator

Home price

The home price is the agreed prix du bien. It affects the loan, LTV and cash required, but it is not the only amount needed at completion. Acquisition costs and some financing costs are added separately.

Down payment and apport personnel

Apport personnel is the buyer’s own contribution. A larger contribution reduces borrowing, monthly payment and LTV. It may improve the strength of an application, but no single deposit percentage guarantees approval.

Keep funds for acquisition costs and emergencies rather than allocating every available euro to the purchase.

Interest rate

Enter the annual taux nominal used to calculate loan interest. This is not the same as TAEG, the annual percentage rate of charge that reflects the broader cost of obtaining the credit. The French Ministry of Economy explains that TAEG can include interest, application charges, required intermediary fees, mandatory insurance and guarantee costs (French Ministry of Economy).

Use the nominal rate for the calculator’s payment formula, but compare lender offers using TAEG and total euro cost.

Loan term and start date

The term determines the number of monthly payments. A longer term normally reduces the mensualité but increases total interest. A shorter term raises the payment but repays principal faster.

The start date is used to estimate the payoff date. The displayed date can change if disbursement is delayed, the rate changes, payments are paused or additional principal is repaid.

Optional Costs and France-Specific Inputs

Property tax and home insurance

The calculator may estimate annual Taxe Foncière as a percentage of the purchase price and divide it by 12. This is a budgeting shortcut only. France’s tax authority calculates Taxe Foncière using the taxable cadastral rental value and rates voted by the relevant local authorities, not simply a universal percentage of the purchase price (impots.gouv.fr).

Assurance Habitation can also be estimated from a rate input. Actual premiums depend on the home, location, occupancy, insured risks, limits, excess and provider.

Borrower insurance

Assurance Emprunteur is separate from the mortgage’s principal and interest. It may cover specified risks such as death, disability or incapacity, subject to the policy. The calculator estimates a monthly amount from the loan and entered insurance rate.

Purchase and guarantee costs

Frais de Notaire are paid around completion and include taxes, disbursements and regulated notarial remuneration. Frais de Garantie relate to the lender’s security, which may involve a mortgage charge, another security or a guarantee provider such as Crédit Logement. Crédit Logement describes its guarantee as an alternative to a mortgage charge, but availability and cost depend on the lender and application (Crédit Logement).

Early repayment

Enter an optional Remboursement Anticipé to test a higher planned monthly outflow. The estimate can show potential interest reduction and an earlier payoff, but the result depends on the contract, timing, amount and any applicable charge.

France Mortgage Calculator Formulas Explained

Loan amount

$$\text{Loan Amount} = \text{Home Price} – \text{Apport Personnel}$$

For a €450,000 property with a €90,000 contribution, the proposed loan is €360,000.

Principal and interest

For a standard amortising loan, the calculator converts the annual nominal rate to a monthly rate and the term to a number of monthly payments. It then calculates a regular principal-and-interest payment using the standard amortisation formula. If the rate is zero, the loan is divided by the number of monthly payments.

Estimated recurring costs

$$\text{Annual Property Tax Estimate} = \text{Home Price} \times \text{Estimated Tax Rate}$$

$$\text{Annual Home Insurance Estimate} = \text{Home Price} \times \text{Insurance Rate}$$

Each annual estimate is divided by 12. These are user-entered planning assumptions, not official assessments.

Borrower insurance

$$\text{Monthly Borrower Insurance} = \text{Loan Amount} \times \text{Insurance Rate} \div 100 \div 12$$

This simplified estimate may differ from a policy priced on initial capital, outstanding capital, age, health, occupation, coverage and other underwriting factors.

Monthly payment and planned outflow

$$\text{Monthly Mortgage Payment} = \text{Principal and Interest} + \text{Property Tax Estimate} + \text{Home Insurance}$$

$$\text{Planned Monthly Outflow} = \text{Monthly Mortgage Payment} + \text{Early Repayment}$$

Borrower insurance should be added separately when estimating actual monthly outflow.

Total payment, interest and cost

$$\text{Total Principal and Interest} = \text{Monthly Principal and Interest} \times \text{Number of Monthly Payments}$$

$$\text{Total Interest} = \text{Total Principal and Interest} – \text{Loan Amount}$$

$$\text{Total Cost} = \text{Monthly Mortgage Payment} \times \text{Number of Monthly Payments}$$

This total cost includes only the calculator’s selected components. It is not every possible cost of French property ownership.

Cash needed

$$\text{Cash Needed} = \text{Apport Personnel} + \text{Frais de Notaire} + \text{Upfront Insurance Fees}$$

Frais de Garantie and other transaction costs may require additional cash depending on the financing and the inputs available.

LTV and payoff date

$$\text{LTV} = \text{Loan Amount} \div \text{Home Price} \times 100$$

LTV indicates the share of the property’s value financed by borrowing. There is no single LTV threshold that applies identically to every French borrower.

$$\text{Estimated Payoff Date} = \text{Mortgage Start Date} + \text{Loan Term}$$

The displayed date remains an estimate and can change if actual disbursement or repayment differs from the assumptions.

Fixed-Rate Mortgages and French Mortgage Rates

Fixed-rate loans are common in France. With a fixed taux nominal, the contractual interest rate does not change during the agreed period, although insurance and ownership costs can still change. Service-Public distinguishes fixed rates from revisable rates and advises comparing TAEG rather than the interest rate alone (Service-Public mortgage guidance).

TAEG makes offers more comparable because it incorporates relevant required costs. A low advertised nominal rate can still be paired with expensive insurance, guarantee or application charges. Compare the mensualité, TAEG, total euro cost, flexibility and borrower-insurance terms.

Some eligible buyers may combine a standard loan with a PTZ, or Prêt à Taux Zéro. The PTZ is a state-supported zero-interest loan for a qualifying main-residence project and must complement other financing; eligibility rules depend on the household and project (Service-Public PTZ guidance). Verify current rules rather than assuming eligibility.

Frais de Notaire and Other Upfront Purchase Costs

The phrase Frais de Notaire is convenient but incomplete. French acquisition costs include transfer taxes or registration charges, disbursements for documents and third parties, and the notary’s regulated remuneration. Most of the amount does not become the notary’s professional fee.

Notaires de France states that acquisition costs are generally around 7% to 8% of the price for an existing property and around 2% to 3% for qualifying new property, but the actual amount depends on current rules and the transaction (Notaires de France). These are planning ranges, not guaranteed percentages.

Reduced acquisition costs can apply to certain new homes, including qualifying VEFA transactions. Check the transaction’s legal and tax treatment before assuming a reduced rate.

Budget separately for:

• Frais de Notaire or acquisition costs
• Frais de Garantie
• Bank application or broker charges
• Initial insurance amounts
• Survey, translation or legal support where needed
• Moving, renovation and furnishing

The calculator’s cash-needed report should include only costs for which the page provides an input. Ask the notary and lender for updated written estimates.

Assurance Emprunteur and the Lemoine Law

Assurance Emprunteur protects repayment under covered events such as death, disability or incapacity. It is not a statutory requirement in every case, but French banks generally require it for a property loan (French Ministry of Economy). Coverage, exclusions, insured share and pricing can vary between borrowers.

Délégation d’assurance means choosing an insurance contract outside the lender’s group policy, provided it meets the lender’s required level of cover. Under the Lemoine Law, borrowers have been able to change qualifying borrower insurance at any time without cancellation fees since 1 September 2022, subject to equivalent guarantees and acceptance procedures (French Ministry of Economy).

Compare premium structure, exclusions, waiting periods, coverage definitions and total cost, not only the monthly price.

Taxe Foncière and Other Property Ownership Costs

Taxe Foncière is a recurring property tax for owners. It is separate from mortgage principal, interest and borrower insurance. The amount depends on the cadastral rental basis, local rates and property circumstances, and can change.

Assurance Habitation is another recurring cost. Apartment owners may also face co-ownership charges and works, while house owners must budget for maintenance and repairs.

Use a previous Taxe Foncière notice when available rather than relying only on a percentage estimate. For a condominium, review the copropriété accounts, meeting minutes and planned works. A realistic French mortgage affordability assessment should leave room for costs that do not appear in the bank instalment.

Early Repayment and Reducing Mortgage Interest

Remboursement Anticipé means repaying part or all of the mortgage before the scheduled date. Additional principal can reduce future interest and may shorten the term. Exact savings require a calculation using the payment date, amount, balance and contract terms.

A French mortgage contract may set conditions for partial early repayment and may provide for an indemnité de remboursement anticipé, or IRA. For a fixed-rate mortgage, official guidance states that the charge cannot exceed both six months of interest on the prepaid principal and 3% of the outstanding capital before repayment, with exemptions in specified circumstances (Service-Public). Contract terms and current law should be checked for the specific loan.

If rates fall, borrowers may also consider Rénégociation de prêt with the existing lender or Rachat de crédit with a new lender. Switching can add early-repayment, guarantee, application, insurance and mortgage-release costs, so compare the total remaining cost rather than only the new rate (Service-Public).

Understanding the Calculator Reports

Mortgage Summary

The summary shows the monthly payment, loan amount, principal and interest, total interest, total paid, total cost under the selected assumptions and estimated payoff date. It is useful for comparing rates, terms and contribution amounts.

Monthly Cost Breakdown

This report separates principal and interest from estimated Taxe Foncière, Assurance Habitation and Assurance Emprunteur. The distinction prevents insurance and ownership costs from being mistaken for mortgage principal.

Cash Needed

The cash report combines apport personnel, entered Frais de Notaire and upfront insurance costs. Add Frais de Garantie when the calculator provides that input. It should not be interpreted as every possible completion expense.

Payoff Preparation

This section shows planned monthly outflow, early repayment, estimated interest savings, possible earlier payoff and LTV. Results are scenarios and may not account for every contractual IRA or lender restriction.

Amortisation Preview

The tableau d’amortissement lists month, payment, principal, interest and remaining balance. It helps buyers understand how the debt declines and provides a baseline for comparing a Remboursement Anticipé.

Use the France Mortgage Calculator to Plan Your Purchase

A France Mortgage Calculator turns a property price and rate into a practical estimate of monthly payments, cash needed and long-term interest. Its most useful role is showing that a French home loan involves more than principal and interest.

Test several scenarios, then compare the estimate with lender offers, insurance quotations, the notary’s acquisition-cost calculation and the property’s tax notice. Use the [Mortgage Affordability Calculator] to test household capacity, the [Extra Payment Calculator] to model early repayment, and the [Mortgage Refinance Calculator] to compare renegotiation or refinancing.

Mortgage calculations are estimates for educational purposes only. Actual mortgage rates, insurance, taxes, fees, guarantees, property costs and lending conditions vary by lender, insurer, location, transaction and borrower circumstances. Check current rules with official French authorities and consult qualified lenders, notaries, insurers or advisers where appropriate.
