Calculate and compare the cost of your mortgage insurance
Updated on
Loan insurance is mandatory to obtain a mortgage in France. It represents a significant cost, often between 10% and 30% of the total loan cost.
This calculator allows you to accurately estimate your insurance cost and compare it with the market average rate for your age.
The insurance rate is a percentage applied to the borrowed amount to calculate your loan insurance cost. It is generally expressed as AEIR (Annual Effective Insurance Rate) and varies according to your profile (age, health, occupation).
The AEIR (Annual Effective Insurance Rate) is the mandatory legal indicator since the decree of October 15, 2014. It is calculated as the difference between the APR with insurance and the APR without insurance. It is the only reliable indicator for comparing insurance offers, as it accounts for the calculation method (initial capital or remaining capital).
Quota represents the coverage level. For a single loan, it is 100%. For a joint loan, each borrower can be insured at 100% (200% total) or 50% each (100% total). In case of death, the quota determines the share of the loan covered.
Yes, the Lemoine law (2022) allows you to change your loan insurance at any time, without fees or penalties. Your bank has 10 business days to respond and can only refuse if the new contract's guarantees are not equivalent (written justification required).

Compare the AEIR (rate), total cost over duration, included guarantees (death, total disability, temporary disability), exclusions and waiting periods. Also check the calculation method: on initial capital (fixed premium) or on remaining capital (degressive premium, often 30-40% cheaper overall).
The average rate varies by age: 0.09% for under 30s, 0.15% for 35-year-olds, 0.40% for 50-year-olds. These rates increase significantly after 60. The market has dropped approximately 27% between 2020 and 2025, a trend continuing in 2026.

Yes, certain sports (scuba diving, skydiving, mountaineering, motor sports) can lead to guarantee exclusions or surcharges. Always declare your sporting activities: a false declaration can void the contract in case of a claim.
The ITT deductible is the period (usually 30, 60 or 90 days) during which the insurer does not compensate you after a work stoppage. A short deductible (30 days) costs more but offers better protection. Civil servants and employees with salary maintenance can opt for 90 days to reduce their premium.
The ordinance of January 5, 2026 strengthens insurer obligations: they must now annually inform each client of their right to cancel at any time (Lemoine law), subject to ACPR sanctions. The ACPR has made verifying commercial practices in loan insurance one of its priorities for 2026, and several banks have been sanctioned for obstructing insurance switch requests.
Ask your bank for the FSI which lists the 11 guarantee equivalence criteria required (from the 18 criteria defined by the CCSF). This is your reference document for comparison.
Use our calculator to estimate costs, then compare several insurer quotes while verifying that each FSI criterion is covered. Compare the AEIR, not the nominal rate.
Once you've chosen your offer, subscribe to the new insurance contract. The insurer will provide you with an insurance certificate and general terms.
Send your bank the substitution request along with the new contract. Send by registered letter or through your bank's online portal.
The bank has 10 business days to accept or refuse. Any refusal must be justified in writing, citing the unmet equivalence criteria. The bank cannot charge fees.
If the refusal seems unjustified, contact the banking mediator. You can also report abusive practices to the ACPR or DGCCRF. Several banks have been sanctioned for obstruction.
