Financial Calculator

Use deterministic calculations instead of ad hoc spreadsheet math when the user needs precise financial outputs.

Use This For

Loan and mortgage math
Investment growth and savings goals
NPV, IRR, and payback analysis
Retirement projections and withdrawal planning
Monte Carlo style risk scenarios

Workflow

Confirm units and assumptions first: rates, compounding, time horizon, taxes, and inflation.
Use
```
scripts/financial_calc.py
```
as the source of truth for the computation.
Return both the answer and the assumptions that materially drive it.

Guardrails

Treat outputs as calculations, not personalized financial advice.
Surface simplifying assumptions and scenario sensitivity.
