What the APR must contain

The annual percentage rate aggregates every cost required to obtain the credit: interest at the nominal rate, required borrower insurance, bank file fees, guarantee cost (surety or mortgage lien) and intermediation fees when using the broker conditions loan access. It is expressed as an annual actuarial rate: the computation equalizes the discounted value of the payments with the funds actually made available, net of upfront costs.

The usury ceiling, a public-order cap

Each quarter, the Banque de France publishes the usury rate per loan category: the maximum APR a lender may charge (previous quarter’s average rate plus one third). For mortgages, categories distinguish fixed-rate loans under 10 years, 10 to under 20 years, 20 years and over, variable-rate loans and bridge loans. Exceeding the ceiling is a criminal offence: a file whose APR flirts with usury must be reworked before submission (insurance, fees, term).

Why the usury margin must be managed

Brokerage fees and insurance enter the APR: on small capitals and short terms, a few hundred euros of fees are enough to cross the ceiling. The professional reflex: compute the full APR at structuring time, test sensitivity (term category, delegated insurance, reduced fees) and document the computation. That is exactly what CourtImmo’s versioned engines do on every file, with a dated usury referential replayable for ACPR audit purposes.

Frequently asked questions

The APR measures the overall credit cost. The TAEA (annual effective insurance rate) isolates the weight of insurance alone: it is the difference between the APR with insurance and the APR without. It must appear on any borrower insurance proposal and allows comparing group contracts with delegation.
