Minimum sentences with no number of prison places: an indirect cost (additional prisoners) that no source read estimates.

Current law, sources and limits of the cost schedule

Current law. At 1 September 2025: 84,311 prisoners for 62,614 operational places, i.e. an occupancy rate of 134.7%. « 15 000 places » plan by 2027, well behind schedule. Modular prisons (target of 3,000 places). Minimum sentences were abolished in 2014.

Horizon. full year 2032, €bn/year

Limits. Investment: €5.55bn / 15,000 ≈ €370k per place, i.e. about €0.06bn per year for 1,000 places if the works are spread over six years. Running costs: about €40k to €60k per place per year, estimated from Title 2 and the operating appropriations of programme 107. This ratio is overestimated because the programme also funds probation (SPIP). Minimum sentences cannot be costed directly: their cost runs through the number of additional prisoners, hence of places. At 134% prison density, additional prisoners without new places cost the budget almost nothing, but worsen overcrowding. Running costs checked against a source: the Cour des comptes (Court of Audit) (2023) gives €105 per day of detention, i.e. about €38m per year for 1,000 prisoners (running costs only, without investment). With investment spread out (about €0.06bn per year for 1,000 places), this gives about €0.10bn for 1,000 places, within the range used. The Council of Europe (SPACE I 2023) gives €127 per day, cited in a National Assembly document. 15,000 plan: 5,411 net places delivered by autumn 2025; the places still to come are published only in gross terms (about 6,500), which prevents costing a moratorium on the remaining places. Rule on public bases (18 October 2026): a moratorium on new places, excluding replacement places, is costed through the parameter as a negative value (extrapolation, flagged as such) on the gross places not yet under construction (2,560 at design-study stage, 1,550 with contracts awarded, i.e. 4,110), converted into net places at the ratio observed for the facilities delivered (5,411 net for 7,384 gross, 73%, which takes out the closures of replaced prisons): about 3,000 net places (editors' calculation; the 2,388 gross places under construction are treated as committed).

How to read these amounts. These are static costs and revenues, with no feedback effect, over a full year: nothing on growth, employment or the revenue that economic activity would gain or lose. A higher net cost does not on its own make a worse policy, nor net savings a better one: each programme rests on an economic model (demand-led stimulus, lower compulsory levies, consolidation of the public accounts…) that the cost schedule does not settle. GDP itself measures a volume of activity, not well-being or the usefulness of what is produced. Economic models and feedback effects.
