Comment fonctionne ce calcul (explication claire)
An emergency fund is based only on your essential "bare-bones" survival expenses—the bills you must pay to keep a roof over your head and food on the table if your income completely stops. It should never be sized off gross income. Sizing scales with your risk profile: stable dual earners need 3 months, typical households need 6 months, and freelancers need 9–12 months.

Limites du modèle et conditions aux limites
While this engine calculates standard actuarial and consumer finance metrics, real-world finance introduces nuances that no automated model can fully predict:
- Assumes tax rates, inflation indices, and APR rates remain static across modeled projections.
- Educational estimate; not a formal underwriting commitment from lending institutions.
- Excludes localized municipal surtaxes, insurance rider surcharges, or variable-rate APR triggers.
