The DFP is calculated by multiplying the disability rating set by the medical expert by a value per point. That value is not fixed by law: it depends on the rating and the victim's age at the date of consolidation, according to the reference guides and case law. The higher the rating and the age, the higher the point is valued.
The DFP compensates the definitive reduction in physical, psychological or intellectual capacity after consolidation, that is, once the victim's condition is stabilised. It covers both the functional after-effects, the permanent pain and the loss of quality of life that persist day to day. It is expressed as a percentage, set by the medical expert.
The calculation rests on two elements:
DFP = rating (%) × value per pointA high rating in a young victim gives the largest amount, because the after-effects weigh on a longer life expectancy.
The value per point has no single statutory source. Practitioners rely on the courts of appeal's indicative reference guide for personal-injury compensation, known as the "Mornet guide", and on recent case law involving comparable ratings and ages. In its September 2025 edition, the value per point ranges from around €880 to €9,020 depending on age and rating. This guide gives a range; case law makes it possible to narrow it down to a specific case.
For a DFP of 15% in a 40-year-old victim, the guide uses a value per point of €2,300, i.e. €34,500 for this head. The same rating in a 70-year-old victim will give a lower amount, the value per point decreasing with age. These orders of magnitude must always be checked against real decisions.
A valuation is all the more solid where it rests on comparable decisions. Comparing a case with rulings involving a similar rating and age makes it possible to justify the value per point used and to anticipate the opposing position. This is the work that Plato, the only AI specialised in personal injury, automates: it ties each amount to its base of more than 84,000 quantified decisions, and every figure remains traceable back to the exhibit it comes from.

Is the DFP the same as the former IPP?
The DFP replaced the IPP (permanent partial disability) with the Dintilhac classification. It is broader: it includes permanent pain and loss of quality of life, not just the loss of physical capacity.
Who sets the DFP rating?
The medical expert, in their report, after consolidation. The lawyer then values the head from that rating; they do not set the rating themselves.
Is the value per point official?
No. It results from indicative reference guides and case law. Two cases with the same rating can reach different amounts depending on age and the decisions used for comparison.
How does age affect the amount?
At an equal rating, a younger victim obtains a higher value per point, because the after-effects apply over a longer lifespan.
Can the DFP be valued automatically?
Yes. A vertical tool such as Plato calculates the head from the rating and proposes a value per point backed by comparable decisions, which speeds up valuation and makes it more reliable.
