Accuracy over approximation
Taxation is complex. We model the real brackets, deductions, shielding and realization rules — not rough percentages. If the law changes, the tax configuration changes with it.
About
Built for clarity over decades.
Most financial tools optimise for this quarter. Wealth Prognosis optimises for the next fifty years — with accurate taxation, transparent calculations and three scenarios side by side.
Why this exists
Personal finance software either stays so simple that it cannot answer real questions, or so complex that only accountants can use it. Tax rules make this worse: fortune tax, property tax, tax shielding, realization tax inside companies — these are not covered well by off-the-shelf tools.
Wealth Prognosis started as a personal project to answer one question: when can I actually retire, accounting for every tax, every asset, every year? What started as a spreadsheet grew into a full planning system with an AI assistant on top.
The result is a system that runs the same year-by-year simulation across pessimistic, realistic and optimistic scenarios and explains, in plain language, what the numbers actually mean for your financial future.
Principles
Long horizons, not just next month
Most planners stop at a 10-year cash flow projection. Wealth Prognosis simulates every year from today until your death year so you can see how decisions compound across an entire life.
Transparent calculations
Every number on every page is traceable back to the rule that produced it. Tax configurations are versioned per year, change rates live on each asset, and the full simulation can be exported to Excel for review.
Privacy-first
Your financial data is the most sensitive data you own. Team-scoped queries, audit stamping and signed download URLs are built into the core — not bolted on.
See it run on your own numbers.
Open the dashboard, add a single asset, and watch the prognosis take shape.
