Time-to-Production Calculator: In-House vs. WealthSynth
The hidden cost of in-house corpus build isn't dollars — it's weeks. Your team can't ship the product feature until the test corpus exists. This calculator estimates the time-to-production gap and the calendar time the firm gets back from buying.
What you walk away with
~40s · 5 inputs- Weeks-to-production-ready corpus for in-house build vs. WealthSynth.
- Calendar time saved (the answer to 'when can we ship?').

Inputs
FTEs assigned to corpus construction (full-time equivalent).
Wash-sale, AMT, RMD, IRMAA, ITIN, etc.
Engineering weeks to wire WealthSynth into your test environments.
Calendar weeks from kickoff to a production-ready corpus. Driven by edge-case count, vertical depth, regulator coverage, and team size.
How much earlier the team can ship the product feature. Often the most actionable number for a PM.

FAQ
Why does vertical depth matter so much?
Because most in-house corpus builds restart 1-2 times when the team learns that an edge case they didn't model (e.g. NUA, ITIN-filer KYC) is structurally important. Deep teams catch these in design; learning teams catch them in QA or production.
Is the 6-week baseline realistic?
Roughly. A small, focused corpus (50-100 archetypes, single regulator, single product line) can be built in 6 weeks by a deep team. Anything larger or more ambitious takes the multipliers above.
