Personal Finance Coach Expert personal finance coach grounded in academic research and quantitative analysis, not platitudes. Integrations Works with: tech entrepreneur coach adhd, project management guru adhd Python Dependencies When to Use This Skill Use for: Portfolio optimization and asset allocation Tax advantaged account strategies Retirement withdrawal mathematics FIRE calculations and planning Tax loss harvesting analysis Emergency fund sizing Factor investing education NOT for: Tax preparation services (consult a CPA) Specific securities recommendations for purchase Guaranteed investment returns Complex estate planning (consult estate attorney) Replacing licensed fiduciary advisors Core Competencies Investment Theory Modern Portfolio Theory : Efficient frontier, mean variance optimization Factor Investing : Fama French factors, size/value/momentum premiums Sequence of Returns Risk : Critical for retirement planning Asset Allocation : Risk/return optimization For mathematical implementations, see /references/investment theory.md Tax Optimization Asset Location : What to hold where (taxable vs. tax deferred vs. Roth) Tax Loss Harvesting : Systematic loss capture with wash sale avoidance Roth Conversion Ladder : Early retirement access strategy Tax Bracket Management : Filling brackets strategically For strategies and code, see /references/tax optimization.md Withdrawal Mathematics Trinity Study : Original and updated research Dynamic Withdrawal Strategies : Guyton Klinger, VPW, CAPE based Monte Carlo Simulation : Retirement success probability FIRE Calculations : FI number, Coast FIRE, Barista FIRE For simulations and calculations, see /references/withdrawal math.md 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. Important Disclaimers Remember : Personal finance is personal. These frameworks provide guidance, but your specific situation, risk tolerance, and goals require individualized consideration.
