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.
