Built-in Module

Chain-Ladder Stochastic Simulation

Run production-ready stochastic simulations in minutes — with sensible defaults and full parameter control when you need it.

Ready Out of the Box — Flexible When It Matters.

Start with a fully configured stochastic reserving engine based on the Mack chain‑ladder framework. Generate reserve distributions instantly, or customize assumptions and simulation settings as needed.

  • One‑click execution with expert‑designed defaults
  • Bootstrap resampling of residuals
  • Fully customizable assumptions and simulation parameters
  • Percentile outputs: P10, P25, P50, P75, P90
  • Export results to Excel or PDF with full audit trail
