For a mortgage of 200,000 euros over 20 years, the answer depends less on the gross salary shown on the payslip than on the regulatory framework that governs the granting of credit in France. The maximum debt ratio, the interest rates charged by banks, and the nature of the income taken into account form a triangle where each side modifies the minimum required salary.
HCSF Rule and 35% Debt Ratio: The Regulatory Lock
Most online simulators display a minimum salary without explaining why this threshold is so rigid. The reason can be summed up in four letters: HCSF. The High Council for Financial Stability has imposed a maximum effort rate of 35%, including borrower insurance, for several years. In March 2026, the HCSF officially confirmed the maintenance of this rule without any easing.
In practical terms, the total monthly payment (principal, interest, insurance) cannot exceed 35% of the borrower’s net income. This ceiling applies equally to a couple or a single borrower. Several political proposals aimed at replacing this criterion with a calculation based on disposable income were rejected between 2024 and 2026, which permanently locks the banks’ calculation method.
There is some flexibility, but it remains regulated: banks can deviate from this rule for 20% of their quarterly files, of which at least 70% must concern primary residences and 30% first-time buyers. A file that slightly exceeds 35% can therefore be accepted, provided that the bank has not exhausted its quota.

Minimum Net Salary for 200,000 Euros over 20 Years: How Rates Change
The necessary salary is not a fixed figure. It fluctuates directly with the interest rates charged by banks. The lower the nominal rate, the lower the monthly payment, and the less the required income is high.
The gap between the rates offered to the best profiles and those applied to less favorable files significantly alters the minimum salary.
Calculation Method Used by Banks
The formula is based on three steps:
- Calculate the monthly payment of the loan (principal + interest) based on the amount borrowed, the rate, and the duration, which is 240 months for 20 years.
- Add the monthly cost of borrower insurance, which varies according to age, health status, and the chosen contract (bank or delegated).
- Divide this total monthly payment by 0.35 to obtain the minimum net income required.
With a rate around 3.10% and insurance representing a significant part of the monthly payment, the necessary net monthly salary is generally between 3,200 and 3,500 euros for a borrower without other ongoing credits. This amount can vary by several hundred euros depending on the rate obtained and the cost of insurance.
Income Taken into Account and Deducted Charges: The Pitfalls of Real Calculation
The “salary” as understood by banks does not always correspond to what the borrower imagines. Not all income is treated the same way.
What the Bank Considers
Net salaries in permanent contracts (excluding trial periods) are included at 100%. Rental income, when it exists, is generally only considered at 70% to account for vacancy risk. Recurring bonuses (13th month, contractual bonuses) are often averaged over the year.
For self-employed workers (TNS), freelancers, and liberal professions, banks typically consider the income from the last three years. A consistently rising profit is more reassuring than an isolated peak. Some institutions apply additional discounts on variable income.
Charges That Reduce Capacity
Any ongoing credit (consumer, auto, revolving) is deducted. A borrower who is already repaying 300 euros per month for an auto loan sees their minimum required salary increase accordingly. Alimony payments are also deducted.
Conversely, a consumer loan paid off a few months before the loan application can free up enough borrowing capacity to make the file acceptable. This is a concrete lever that banks examine closely.
Borrower Insurance: The Underestimated Item That Changes the Required Salary
Since the implementation of the 35% rule including insurance, the cost of insurance directly impacts the calculation of the minimum salary. A 30-year-old borrower in good health will pay for insurance much lower than that of a 50-year-old borrower with medical history.
Delegating insurance (choosing an external insurer rather than the bank’s group contract) often helps reduce this cost. The savings made on insurance directly translate into a lower minimum salary, as the total monthly payment decreases. On a loan of 200,000 euros over 20 years, this difference can represent several tens of euros per month, resulting in a few hundred euros difference in the required income.
Banks that offer attractive rates sometimes compensate with a more expensive group insurance. Comparing only the nominal rate is not enough: it is the APR (annual percentage rate), which includes all fees, that allows for reliable comparisons between two offers.
File at the Limit of 35%: Real Margins for Maneuver
A file that reaches exactly 35% debt is not automatically rejected, but it is also not automatically accepted. The bank then examines the disposable income (what remains after paying all fixed charges), available savings, and job stability.
A personal contribution, even modest, plays a decisive role. It reduces the amount borrowed, thus the monthly payment, and signals to the bank a capacity for savings. For a loan of 200,000 euros, a contribution covering at least the notary and guarantee fees is generally expected.
The question of the salary needed to borrow 200,000 euros over 20 years therefore does not have a unique answer. The rate obtained, the cost of insurance, ongoing credits, and the commercial policy of each bank create significant discrepancies from one file to another. Working on these variables before submitting a file remains the best way to optimize chances.
