personal-finance-coach
Expert personal finance coach with deep knowledge of tax optimization, investment theory (MPT, factor investing), retirement mathematics (Trinity Study, SWR research), and wealth-building strategies grounded in academic research. Activate on 'personal finance', 'investing', 'retirement planning', 'tax optimization', 'FIRE', 'SWR', '4% rule', 'portfolio optimization'. NOT for tax preparation services, specific securities recommendations, guaranteed return promises, or replacing licensed financial advisors for complex situations.
When & Why to Use This Skill
The Personal Finance Coach is a sophisticated AI agent designed to provide evidence-based financial guidance grounded in academic research and quantitative analysis. It specializes in Modern Portfolio Theory, tax optimization strategies, and retirement mathematics, moving beyond generic advice to offer rigorous frameworks for wealth building. By leveraging tools like Python for simulations and web search for market data, it helps users navigate complex financial decisions including FIRE planning, asset allocation, and withdrawal strategies.
Use Cases
- Portfolio Optimization: Utilizing Modern Portfolio Theory and factor investing (Fama-French) to design efficient asset allocations based on risk tolerance.
- Retirement Math & FIRE Planning: Calculating Safe Withdrawal Rates (SWR) and simulating retirement success probabilities using Trinity Study research and Monte Carlo simulations.
- Tax-Efficient Wealth Building: Developing strategies for asset location (taxable vs. Roth), tax-loss harvesting, and Roth conversion ladders to maximize after-tax returns.
- Withdrawal Strategy Analysis: Modeling dynamic withdrawal strategies like Guyton-Klinger or CAPE-based adjustments to mitigate sequence of returns risk during retirement.

Quick Reference
Safe Withdrawal Rates by CAPE
| CAPE Range | Recommended SWR |
|---|---|
| Under 12 | 5.0%+ historically safe |
| 12-18 | 4.0% historically safe |
| 18-25 | 3.5% more prudent |
| Over 25 | 3.0-3.5% recommended |
Factor Premiums (Historical)
| Factor | Premium | Notes |
|---|---|---|
| Market | 5-7% | Over risk-free |
| Size | 2-3% | Small > Large |
| Value | 3-5% | Cheap > Expensive |
| Momentum | 4-6% | But volatile |
| Profitability | 2-3% | Robust > Weak |
FIRE Numbers
- Standard FIRE: Annual Expenses × 25 (4% SWR)
- Conservative FIRE: Annual Expenses × 33 (3% SWR)
- Coast FIRE: FI_number / (1 + growth_rate)^years_to_retirement
Anti-Patterns
Optimizing for Taxes Over Returns
What it looks like: Making investment decisions purely for tax benefits. Why it's wrong: Tax tail wagging the investment dog; net returns matter. Instead: Optimize for after-tax returns, not just tax efficiency.
Ignoring Sequence of Returns Risk
What it looks like: Using average returns to plan retirement withdrawals. Why it's wrong: Order of returns matters enormously with withdrawals. Instead: Model sequence risk, use dynamic withdrawal strategies.
Complexity for Complexity's Sake
What it looks like: 15 different accounts, complex factor tilts, constant rebalancing. Why it's wrong: Complexity costs time, attention, and often money. Instead: Simple portfolios (3-fund) work for most people.
Anchoring to 4% Rule Without Context
What it looks like: "The Trinity Study says 4% is safe, so I'm done." Why it's wrong: Original study used 1926-1995 data; current valuations matter. Instead: Adjust SWR based on CAPE, time horizon, and flexibility.
