Financial Health Score (0–100)

Formula: Σ(dimension_score × weight) × 10

Interpretation:

• 0–30: Financial emergency — stop bleeding first
• 31–50: Foundation building — clear debt, build emergency fund
• 51–70: Growth phase — invest aggressively
• 71–85: Optimization — tax efficiency, alternative assets
• 86–100: Wealth preservation — estate planning, philanthropy

The 50/30/20 Evolved Framework

Rule: Pay yourself first. Automate savings before spending hits checking.

Expense Audit Checklist

• List ALL subscriptions — cancel anything unused in 30 days
• Compare insurance rates annually (auto, home, life)
• Negotiate recurring bills (phone, internet, insurance)
• Track "latte factor" spending for 1 month — quantify daily habits
• Check for duplicate charges and forgotten free trials
• Review credit card annual fees vs. benefits actually used
• Calculate cost-per-use for gym, memberships, services
• Identify spending that doesn't align with stated goals

Phase 3: Debt Destruction

Debt Inventory

debts:
  - name: "Credit Card A"
    balance: 5000
    interest_rate: 22.9
    minimum_payment: 125
    type: "revolving"  # revolving | installment | mortgage
    tax_deductible: false
    priority: 1  # calculated below

Strategy Selection

Debt Priority Rules

1. Emergency: Anything in collections or at risk of legal action
2. Toxic: Interest >15% (credit cards, payday loans) — kill these ASAP
3. Moderate: Interest 5–15% (personal loans, auto) — accelerate but don't obsess
4. Productive: Interest <5% and tax-deductible (mortgage, student) — minimum payments, invest the rest

Payoff Calculator

Months to payoff = -log(1 - (balance × rate/12) / payment) / log(1 + rate/12)
Total interest = (payment × months) - balance

Phase 4: Emergency Fund & Insurance

Emergency Fund Sizing

Where to keep it: High-yield savings account (HYSA) or money market. NOT invested. Liquidity is the point.

Insurance Checklist

Phase 5: Investment Strategy

Asset Allocation by Risk Profile

Age-Based Rule of Thumb

Stock allocation = 120 - your age (aggressive)
Stock allocation = 110 - your age (moderate)
Stock allocation = 100 - your age (conservative)

Core Portfolio Construction

3-Fund Portfolio (Simple, Effective):

1. US Total Market Index (VTI/VTSAX) — 60%
2. International Total Market (VXUS/VTIAX) — 30%
3. US Total Bond Market (BND/VBTLX) — 10%

5-Fund Portfolio (More Control):

1. US Large Cap (VOO/S&P 500) — 40%
2. US Small Cap Value (VBR/AVUV) — 15%
3. International Developed (VEA) — 20%
4. Emerging Markets (VWO) — 10%
5. Bonds (BND or TIPS) — 15%

Factor Tilts (Advanced)

Rule: Factor investing only after core is solid. Don't tilt >30% of equity to any factor.

Phase 6: Tax-Advantaged Accounts

Account Priority Order (US)

1. 401(k) to employer match — 100% return, always max this first
2. HSA (if eligible) — triple tax advantage (deduction + growth + withdrawal)
3. Roth IRA — if income eligible; tax-free growth forever
4. 401(k) remainder — max annual contribution ($23,500 in 2025)
5. Mega backdoor Roth — if plan allows (up to $69,000 total)
6. Taxable brokerage — after maxing all sheltered accounts
7. 529 Plan — if kids' education is a goal
8. I-Bonds — $10K/year limit, inflation protection

Roth vs. Traditional Decision

Rule of thumb: If marginal rate <22%, strongly favor Roth. If >32%, favor Traditional. Between = split.

Tax Loss Harvesting

• Sell losing positions to offset gains (up to $3,000/year vs. ordinary income)
• Immediately buy a similar (not "substantially identical") fund to maintain allocation
• Track 30-day wash sale window — can't rebuy the same security
• Automate end-of-year tax review: harvest before December 31
• Carry forward unused losses indefinitely

Phase 7: Real Estate

Buy vs. Rent Calculator

buy_vs_rent:
  # Buying costs
  home_price: 0
  down_payment_pct: 20
  mortgage_rate: 7.0
  property_tax_rate: 1.2
  insurance_annual: 1500
  maintenance_pct: 1.0  # of home value per year
  hoa_monthly: 0
  closing_costs_pct: 3.0
  
  # Renting costs
  monthly_rent: 0
  renters_insurance: 150  # annual
  rent_increase_annual: 3.0  # percent
  
  # Assumptions
  home_appreciation: 3.0  # annual percent
  investment_return: 8.0  # what you'd earn investing the down payment
  holding_period_years: 7
  marginal_tax_rate: 24

Price-to-rent ratio: Home price ÷ annual rent

• <15: Buying favored
• 15–20: Close call, run the numbers

• 20: Renting likely cheaper

Investment Property Analysis

Cash-on-Cash Return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested
Cap Rate = Net Operating Income ÷ Property Value
The 1% Rule = Monthly Rent ≥ 1% of Purchase Price (screening filter)
50% Rule = Operating expenses ≈ 50% of gross rent (quick estimate)

Phase 8: Alternative Investments (5–15% of Portfolio)

Bitcoin Position Sizing

Rules:

• Only invest what you can afford to lose entirely
• Dollar-cost average, don't lump sum
• Self-custody above 0.1 BTC (hardware wallet)
• Never sell in panic — have an exit plan before buying
• Understand the 4-year halving cycle

Phase 9: Retirement Planning

FIRE Number Calculation

Annual expenses × 25 = FIRE number (4% withdrawal rate)
Annual expenses × 33 = Conservative FIRE (3% withdrawal rate)

Withdrawal Strategy

1. 4% Rule (Trinity Study): Withdraw 4% year 1, adjust for inflation thereafter
2. Variable Percentage: Adjust withdrawal based on portfolio performance
3. Bucket Strategy:
   • Bucket 1 (1–2 years): Cash/HYSA — immediate needs
   • Bucket 2 (3–7 years): Bonds/conservative — medium term
   • Bucket 3 (8+ years): Stocks — long-term growth

Retirement Account Withdrawal Order

1. Taxable accounts first (lowest tax impact)
2. Tax-deferred (Traditional IRA/401k) — manage brackets
3. Roth last (tax-free growth as long as possible)
4. HSA absolute last (triple advantage, let it compound)

Phase 10: Wealth Protection & Estate Planning

Estate Planning Checklist

• Will — who gets what, guardian for minor children
• Living trust — avoid probate, privacy
• Power of attorney — financial decisions if incapacitated
• Healthcare directive — medical decisions if incapacitated
• Beneficiary designations — 401k, IRA, life insurance (these override your will!)
• Digital estate plan — passwords, crypto keys, online accounts
• Letter of intent — non-binding wishes, funeral preferences
• Annual review — update after marriage, divorce, birth, death

Asset Protection Strategies

Phase 11: Monitoring & Rebalancing

Weekly Review (5 minutes)

• Check account balances for anomalies
• Review any pending transactions
• Note any income or expense changes

Monthly Review (30 minutes)

monthly_review:
  date: "YYYY-MM-DD"
  net_worth_change: 0
  savings_rate_actual: 0  # target vs actual
  budget_variance:
    over_categories: []
    under_categories: []
  debt_paydown: 0
  investment_contributions: 0
  notable_events: ""
  next_month_adjustments: ""

Quarterly Rebalancing

1. Calculate current allocation vs. target
2. If any asset class drifts >5% from target → rebalance
3. Prefer rebalancing with new contributions (no tax events)
4. If selling required, harvest losses first
5. Document rationale for any allocation changes

Annual Financial Review

• Update net worth snapshot
• Recalculate financial health score
• Review and adjust investment allocation
• Max out tax-advantaged accounts
• Review insurance coverage needs
• Check beneficiary designations
• Tax loss harvest before December 31
• Review estate plan documents
• Set next year's savings/investment goals
• Check credit reports (annualcreditreport.com)

Compound Growth Reference

Rule of 72: Years to double = 72 ÷ annual return percentage

Common Mistakes to Avoid

1. No emergency fund — investing while one bad month means credit card debt
2. Lifestyle inflation — earning more ≠ spending more
3. Market timing — time IN the market beats timing the market
4. Ignoring fees — 1% annual fee compounds to 25%+ of wealth over 30 years
5. Single stock concentration — your company stock isn't diversification
6. Emotional decisions — selling in crashes, buying in euphoria
7. Ignoring tax drag — holding growth in taxable, bonds in sheltered
8. No rebalancing — drift destroys your risk profile
9. Skipping insurance — one event can wipe decades of saving
10. Analysis paralysis — a good plan now beats a perfect plan never
