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
1. Confirm units and assumptions first: rates, compounding, time horizon, taxes, and inflation.
2. Use scripts/financial calc.py as the source of truth for the computation.
3. 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.
