Rating is not a spreadsheet export. It is an executable financial engine.
Facio provides high-performance rating calculation APIs supporting complex underwriting matrices, multi-variable risk pricing, pro-rata endorsement recalculation, and continuous ledger alignment.
The operational problem
Traditional rating engines are black boxes embedded inside legacy policy administration systems or fragile spreadsheets passed between underwriters. When pricing rules change, updates take months or introduce hidden calculation errors during mid-term endorsements.
How it works
Facio's rating engine executes multi-variable algorithms sub-85ms. Rating logic is versioned and effective-dated, ensuring that past quotes and policies can be exactingly recalculated against their original rating version.
API-first calculation engine
Query rates via REST or Python APIs for instant quote generation and risk scoring.
Policy fork recalculation
When a policy fork is created for an MTA, rating logic evaluates exposure delta and computes pro-rata or short-rate premium differences.
Continuous ledger synchronization
Premium outputs flow into transaction ledgers, keeping accounting and policy records aligned.
Configuration and control
Actuaries and underwriters configure rate tables, factors, and minimum premiums without touching core codebase logic.
