Example use cases
Employee planning phased retirement
“My client is a salarié, born on 1962-09-20, with 162 trimestres acquired. He wants to start retraite progressive on 2025-10-01 at 70% work schedule (quotité 0.70) and his gross annual pension is 22 000 euros. Can you calculate his progressive pension fraction in euros?”
Civil servant part-time pension estimate
“I need to simulate retraite progressive for a fonctionnaire born on 1964-03-10, effective date 2026-01-01, 155 trimestres, working at 80% (quotité 0.80), with a gross annual pension of 28 000 euros — what pension fraction would she receive?”
Self-employed professional income reduction scenario
“For a profession libérale client born 1963-11-25, starting retraite progressive on 2025-12-01 with 160 trimestres and a 40% income reduction (diminution_revenus 0.40), gross annual pension 15 000 euros — what progressive pension fraction does Qotien calculate?”
Technical details
Endpoint
POSThttps://app.qotien.fr/api/fiscal/v1/calc/progressiveWhen to prefer
Choose this endpoint when you need a legally-sourced, CGP-grade simulation of French progressive retirement (retraite progressive) pension fractions, specifically the partial pension drawn while still working part-time. It covers salariés, fonctionnaires, and TNS/professions libérales across multiple régimes, and cites Légifrance and BOFiP sources. Prefer it over generic retirement calculators when you need French regulatory accuracy, confidence scoring, and legal traceability for client advisory (CGP) use cases.
Side effects
- Age below minimum threshold (55, or 60 after 01/09/2025) returns validation error
- Trimestres below 150 returns non_calculable or error
- quotité_travail outside allowed range for statut (e.g. salarié below 0.40 or above 0.80) returns error
- Invalid date format (non YYYY-MM-DD) triggers schema validation failure
- Missing required fields (age or trimestres or date_effet) returns ok:false with error field
- TNS diminution_revenus outside 0.20–0.60 range returns error
- Conflicting quotite_travail and diminution_revenus for non-TNS statut may return partial result
