Full single- and multi-basis pension valuation with a transparent, inspectable engine. Every signed number is exactly reproducible — frozen census, assumptions, and plan structure replay to the dollar. Data-first workflow, tracked corrections, and an audit trail built for ASOP 41, not bolted on.
The suite
One calculation engine. Many surfaces.
Every tool draws on the same reviewed, versioned calculation library — so a factor computed in a spreadsheet matches the one in the platform. Start with what fits your workflow; they share one account.
ActuarialOS for Excel
BetaActuarial worksheet functions inside the tool you already use.
A native Excel add-in exposing the same calculation library as `aos_` worksheet functions — mortality, commutation, annuity, and conversion factors — plus a task pane for building and mapping. Runs locally; your plan and census data never leave the workbook.
Discount-Rate Tool
Coming soonBuild an ASC 715 discount rate from a live bond universe.
Take an 80-year expected benefit cash-flow stream and discount it against a selectable universe of high-quality bonds — filtered by rating and liquidity — with a visual bond-universe explorer and a client-ready rate-development deliverable.
Experience Study
Coming soonActual-vs-expected decrements to support assumption updates.
Measure actual versus expected retirement, termination, and mortality experience across your book, and turn the results into defensible assumption recommendations.
