Run deterministic financial calculations for loans, investments, NPV, and retirement.

  • Solves precise financial modeling without ad hoc spreadsheet math.
  • Depends on scripts/financial_calc.py for all computations.
  • Confirms units, rates, compounding, and assumptions before calculating.
  • Returns the answer along with key assumptions and scenario sensitivity.

# 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.
