ActuarialOS

Built for pension actuaries

Pension valuation you can
reproduce to the dollar.

A modern platform for defined benefit work. Frozen inputs, an engine you can inspect, and an Excel add-in that runs on the same numbers.

Free during the beta · your census never leaves your machine

The platform

Built like audited financial software, not a web app.

Built for mid-market consulting firms: every calculation inspectable, every result reproducible.

Every number is reproducible

Valuations read a frozen triple — census, assumptions, plan structure — from the plan-year record. Re-run a signed year and it reproduces to the dollar. No drift, no 'which file was final'.

The actuary stays in control

No black box. Trace any liability figure back to the participant, the formula applied, the assumption used, and the data that fed it. When you sign the report, you can defend every line.

Data first, not formulas first

Import, clean, and validate census data immediately — because 60% of valuation time is data, not calculations. Corrections are tracked as snapshots, never overwritten.
