# fire-planner
|
||
|
||
Risk-adjusted, tax-minimised FIRE retirement planner. Consumes today's
|
||
portfolio, savings rate, and RSU vest schedule from sibling services
|
||
(`wealthfolio`, `payslip-ingest`, `hmrc-sync`) and returns the after-tax
|
||
probability of success for each combination of jurisdiction, withdrawal
|
||
strategy, and "year you break UK tax residency".
|
||
|
||
## Layout
|
||
|
||
- `fire_planner/` — package
|
||
- `tax/` — per-jurisdiction tax engines (UK, nomad, Malaysia, Thailand,
|
||
Cyprus, Bulgaria)
|
||
- `returns/` — Shiller 1871+ data + block bootstrap sampler
|
||
- `strategies/` — Trinity 4% SWR, Guyton-Klinger guardrails, VPW
|
||
- `ingest/` — pulls from `wealthfolio` / `payslip-ingest` / `hmrc-sync`
|
||
- `simulator.py` — vectorised NumPy MC engine
|
||
- `scenarios.py` — Cartesian product over (jurisdiction × strategy ×
|
||
leave-UK-year × glide)
|
||
- `app.py` — FastAPI on-demand `/recompute`
|
||
- `__main__.py` — `click` CLI: `ingest`, `simulate`, `recompute-all`,
|
||
`migrate`
|
||
|
||
## Common commands
|
||
|
||
```bash
|
||
poetry install
|
||
pytest -v
|
||
mypy .
|
||
ruff check .
|
||
yapf --recursive .
|
||
|
||
# Run migrations against the local DB:
|
||
DB_CONNECTION_STRING=postgresql+asyncpg://... alembic upgrade head
|
||
|
||
# CLI
|
||
DB_CONNECTION_STRING=... python -m fire_planner ingest
|
||
DB_CONNECTION_STRING=... python -m fire_planner simulate --scenario=cyprus-vpw-leave-y3
|
||
DB_CONNECTION_STRING=... python -m fire_planner recompute-all
|
||
```
|
||
|
||
## Schema
|
||
|
||
Six tables in `fire_planner` schema on `pg-cluster-rw`:
|
||
|
||
- `account_snapshot` — daily NW per account (Wealthfolio)
|
||
- `scenario` — Cartesian-product scenario definition
|
||
- `mc_run` — execution metadata + summary stats per (scenario, run_at)
|
||
- `mc_path` — sparse storage (top decile, bottom decile, median)
|
||
- `projection_yearly` — deterministic point projection per scenario
|
||
- `scenario_summary` — denormalised fast-read for Grafana
