Simulate an early repayment

For a French mortgage, the law caps the fees at the lower of two amounts: 6 months of interest on the capital repaid, at the loan rate, and 3% of the outstanding capital before the repayment (Consumer Code, art. R313-25). Your contract may set less, or none at all: check it, and enter the amount it sets in the calculator.

No fee is due when the repayment follows the sale of the property after the borrower or their spouse changes place of work, the borrower's death, or a forced end of their professional activity (Consumer Code, art. L313-48). Many contracts also include negotiated waivers.

Shortening the term keeps the same payment and ends the loan sooner: it saves the most interest. Lowering the payment keeps the same end date and eases your monthly budget, for a smaller interest saving. The calculator works out both.

Your contract may refuse a partial repayment of 10% or less of the amount borrowed, unless it pays off the loan. Above that, you can repay early, in part or in full, at any time.

Repaying is all the more worthwhile when done early (interest weighs most at the start of the loan) and when the loan rate is high. Compare the net saving, fees deducted, with what the same sum would earn invested, and keep an emergency fund available.

The calculator counts interest without insurance. If your insurance is based on the outstanding capital, it also drops after an early repayment; based on the amount borrowed, it stays the same until the end, unless amended.
