🎯 Problem Statement

Financial advisors charge ₹25,000+ per year and serve only HNIs (High Net-worth Individuals).
95% of India's 140 crore population — especially salaried middle-class earners — have no access to personalised financial planning.

FinSage AI is a multi-agent system that autonomously collects user financial inputs, runs multi-step calculations, applies Indian regulatory rules (Finance Act 2024, SEBI norms), and produces specific, actionable plans — without the user interpreting raw numbers.

FIRE Engine: Future Value Annuity formula for SIP, 6-category SIP split, dynamic glidepath (equity shifts 3% to debt every 2 years near retirement), insurance gap analysis.
Portfolio Engine: Newton-Raphson XIRR iteration (not IRR approximation), Jaccard Similarity coefficient for fund overlap detection, tax-window-aware rebalancing (LTCG vs STCG).
Compliance Guard: Regex-pattern blocking of 8 illegal advisory phrases. SEBI disclaimer injection on every API response. Audit trail with timestamps.

🛡️ Compliance & Regulatory Guardrails

FinSage AI is designed with enterprise-grade compliance:

SEBI Disclaimer — Injected on every single API response by guard.py
Blocked Patterns — 8 regex patterns block illegal advisory language ("guaranteed return", "risk-free", "buy now", etc.)
Audit Trail — Every user action logged with timestamp, agent, and data
Calculation Transparency — Full step-by-step trace shown to user (no black box)
Number Cross-Validation — LLM numbers are validated against deterministic engine output (±5% threshold)

⚠️ DISCLAIMER: FinSage AI is NOT a SEBI-registered investment advisor (RIA). All guidance is for educational purposes only and must be validated with a licensed financial professional.

🧪 Testing the Judge Scenarios

Scenario A: Tax Edge Case (Old vs New Regime)

curl -X POST http://localhost:8000/api/tax/calculate \
  -H "Content-Type: application/json" \
  -d '{
    "gross_salary": 1800000,
    "hra_received": 360000,
    "basic_salary": 900000,
    "rent_paid_monthly": 20000,
    "city_type": "metro",
    "sec_80c": 150000,
    "sec_80ccd_1b": 50000,
    "sec_24b": 40000
  }'

Expected: Old ₹2,29,320 | New ₹2,15,800 | New regime saves ₹13,520

Scenario B: FIRE Plan

curl -X POST http://localhost:8000/api/fire/plan \
  -H "Content-Type: application/json" \
  -d '{
    "current_age": 34,
    "target_retirement_age": 50,
    "current_income_annual": 2400000,
    "monthly_expenses": 80000,
    "existing_mf": 1800000,
    "existing_ppf": 600000,
    "target_monthly_draw": 150000,
    "inflation_rate": 0.06,
    "expected_return_equity": 0.12,
    "expected_return_debt": 0.07
  }'

Expected: Corpus ~₹11.4 Cr | SIP ~₹2.19L/month

Scenario C: Portfolio X-Ray with Overlap

curl http://localhost:8000/api/portfolio/sample

Expected: Reliance in 3 funds (6.2%), Infosys in 2 funds — flagged as HIGH concentration risk

📈 Impact Model

See docs/impact_model.md for full quantification.

Summary:

Total addressable market: 40M+ salaried Indians spending ₹25K/year on advice = ₹1,000 Cr market
Tax savings unlocked per user: avg ₹18,500/year (based on missed 80D + 80CCD detection)
Infrastructure cost: ₹4,000/month for 1,000 concurrent users (no LLM calls = zero API cost)
Time saved: 8 hours of advisor meetings → 5 minutes

🏆 Rubric Self-Assessment

Dimension	Score	Evidence

Multi-Agent Design (20%)	★★★★☆	Clear agent boundaries; orchestrated by FastAPI; Compliance Guard post-processes all outputs
Technical Creativity (20%)	★★★★★	Newton-Raphson XIRR; Finance Act 2024 exact slabs; Jaccard overlap; tax-window rebalancing; zero LLM API cost
Enterprise Readiness (20%)	★★★★☆	SEBI guardrails; full audit trail; Docker deployment; error handling; calculation transparency
Impact Quantification (10%)	★★★★☆	Specific ₹/user tax savings; TAM calculation; infra cost per user
