How French APL Housing Benefit (CAF) is Estimated in 2026

The APL (Aide Personnalisée au Logement) is one of the most widely used social benefits in France, distributed by the CAF (Caisse d’Allocations Familiales) or the MSA to help tenants, students, and low-income households reduce their monthly rent burden.

If you are living in France or moving to the country as an expat or international student, calculating your monthly housing benefit entitlement is essential for managing your living expenses.

How the CAF Calculates APL in 2026

Under the “real-time” (en temps réel) APL reform in France, housing aid calculations are updated automatically using your net income from the last 12 rolling months, rather than tax returns from two years prior.

The exact amount of APL you receive depends on four primary factors:

1. Net Monthly Household Income: Your total earnings over the past 12 months. If you are also calculating your net take-home salary from your contract, use our Gross to Net Salary Calculator.
2. Monthly Rent Amount (Excl. Charges): The baseline rent capped by geographic zone limits (Zone 1: Paris & Île-de-France; Zone 2: Large urban areas; Zone 3: Rest of France).
3. Household Composition: Whether you live alone, as a couple, or have dependent children.
4. Property Accreditation: The rental property must be designated as your primary residence (résidence principale) and meet French health and security standards.

Student Eligibility & CAF Considerations

For international and French students, renting an apartment or university studio often qualifies for APL subsidies. However, there are strategic financial considerations:

• Parental Tax Dependency: If an international student or young worker claims APL independently, they cannot be claimed as a dependent on their parents’ French tax declaration for family allowance purposes.
• Income Thresholds: Students with low or zero taxable income often receive maximum APL benefit allocations.
