Questions to Ask the User First
- Age and retirement target: How old are you? When do you want to retire?
- Current investments: Do you have any existing investment accounts? (401k, IRA, brokerage, etc.) What is in them?
- Income: What is your gross annual income? Do you expect it to increase, stay flat, or decrease?
- Emergency fund: Do you have 3-6 months of expenses saved in cash or cash equivalents?
- Debt status: Do you have any high-interest debt (above 6-7%)? (Pay this off before investing beyond employer match)
- Risk tolerance: How would you react if your portfolio dropped 30% in a year? (Scale: panic-sell / lose sleep but hold / buy more / doesn't bother me)
- Time horizon: When will you need this money? (Under 3 years, 3-10 years, 10+ years)
- Employer benefits: Does your employer offer a 401k/403b? Is there an employer match? What funds are available?
- Tax situation: What is your marginal tax bracket? Do you expect to be in a higher or lower bracket in retirement?
- Investment knowledge: Beginner, intermediate, or advanced?
Core Investment Principles (Bogleheads Philosophy)
- Develop a workable plan -- Set goals before picking investments
- Start early and invest regularly -- Time in the market beats timing the market
- Never bear too much or too little risk -- Match risk to time horizon and tolerance
- Diversify -- Own the entire market, not individual stocks
- Never try to time the market -- Stay the course through volatility
- Use index funds when possible -- Low cost, broad diversification, tax efficient
- Keep costs low -- Expense ratios matter enormously over decades
- Minimize taxes -- Use tax-advantaged accounts; be aware of tax implications
- Invest with simplicity -- A three-fund portfolio can outperform complex strategies
- Stay the course -- Do not react emotionally to market movements
Asset Allocation by Age and Risk
The Age-Based Rule of Thumb
A common starting point: hold your age in bonds, the rest in stocks.
- Age 25: 75% stocks / 25% bonds (aggressive: 90/10)
- Age 35: 65% stocks / 35% bonds (aggressive: 80/20)
- Age 45: 55% stocks / 45% bonds (aggressive: 70/30)
- Age 55: 45% stocks / 55% bonds (moderate: 50/50)
- Age 65: 35% stocks / 65% bonds (conservative: 30/70)
Modern adjustment: Many advisors now suggest "age minus 10" or "age minus 20" in bonds, given longer life expectancies and low bond yields.
Risk-Based Allocation
RISK ASSESSMENT
===============
Answer these questions (1 = strongly disagree, 5 = strongly agree):
1. I can tolerate a 20%+ portfolio drop without selling: ___
2. I won't need this money for 10+ years: ___
3. I have stable income and a full emergency fund: ___
4. I have experience investing through a downturn: ___
5. Growing my money is more important than protecting it: ___
TOTAL SCORE: ___
Score 5-10: Conservative (30-40% stocks / 60-70% bonds)
Score 11-17: Moderate (50-60% stocks / 40-50% bonds)
Score 18-25: Aggressive (70-90% stocks / 10-30% bonds)
The Three-Fund Portfolio
The foundation of Bogleheads investing. Three index funds cover the entire global market:
| Fund | Purpose | Example (Vanguard) | Expense Ratio |
|---|
| US Total Stock Market | Domestic equity | VTSAX / VTI | 0.03% |
| International Stock Market | Foreign equity | VTIAX / VXUS | 0.07% |
| US Total Bond Market | Fixed income | VBTLX / BND | 0.03% |
Sample Allocations
AGGRESSIVE (age 25-35, high risk tolerance):
US Total Stock: 60%
International Stock: 30%
US Total Bond: 10%
MODERATE (age 35-50, medium risk tolerance):
US Total Stock: 40%
International Stock: 20%
US Total Bond: 40%
CONSERVATIVE (age 55+, low risk tolerance):
US Total Stock: 25%
International Stock: 15%
US Total Bond: 60%
Alternative for maximum simplicity: Use a target-date retirement fund (e.g., Vanguard Target Retirement 2055). It holds the three-fund portfolio and automatically adjusts allocation as you age. Slightly higher expense ratio but zero maintenance.
401(k) / IRA Optimization
Contribution Priority Order (The Investment Waterfall)
Follow this order to maximize tax advantages and employer benefits:
INVESTMENT PRIORITY WATERFALL
=============================
Step 1: Employer 401k match --> Contribute enough to get the FULL match
(This is free money -- 50-100% instant return)
Step 2: Pay off high-interest debt --> Anything above 6-7% APR
Step 3: Max out HSA (if eligible) --> $4,150 individual / $8,300 family (2024)
(Triple tax advantage: deductible, grows tax-free, tax-free for medical)
Step 4: Max out Roth IRA --> $7,000/year ($8,000 if 50+) (2024)
(If over income limits, consider backdoor Roth)
Step 5: Max out 401k --> $23,000/year ($30,500 if 50+) (2024)
Step 6: Taxable brokerage account --> Invest in tax-efficient index funds
Step 7: Additional options --> 529, mega backdoor Roth, I-bonds
Roth vs. Traditional Decision
ROTH vs TRADITIONAL DECISION FRAMEWORK
=======================================
Choose TRADITIONAL (pre-tax) if:
[ ] Current marginal tax rate is HIGH (32%+)
[ ] You expect LOWER income in retirement
[ ] You want to reduce current taxable income
[ ] You are in your peak earning years
Choose ROTH (after-tax) if:
[ ] Current marginal tax rate is LOW (22% or below)
[ ] You expect HIGHER income in retirement
[ ] You are early in your career
[ ] You want tax-free withdrawals in retirement
[ ] You want no Required Minimum Distributions (RMDs)
When in doubt:
- Split contributions between both (diversify your tax exposure)
- Younger = lean Roth; older = lean Traditional
Dollar-Cost Averaging (DCA)
What it is: Investing a fixed dollar amount at regular intervals regardless of market price.
How to implement:
- Set up automatic contributions (monthly or per paycheck)
- Invest the same amount each time
- Do not try to time purchases based on market conditions
- Continue through market downturns (you are buying shares at a discount)
DCA EXAMPLE
===========
Monthly investment: $500
Month 1: Share price $50 --> Buy 10.0 shares
Month 2: Share price $40 --> Buy 12.5 shares (market down -- you get MORE shares)
Month 3: Share price $45 --> Buy 11.1 shares
Month 4: Share price $55 --> Buy 9.1 shares
Month 5: Share price $50 --> Buy 10.0 shares
Total invested: $2,500
Total shares: 52.7
Average cost per share: $47.44 (lower than average price of $48.00)
Lump sum vs. DCA: Statistically, lump sum investing beats DCA about 2/3 of the time (because markets generally go up). But DCA reduces regret risk and is psychologically easier. If you have a large sum and are nervous, DCA over 6-12 months is a reasonable compromise.
Rebalancing Strategy
Why Rebalance
Over time, stocks and bonds grow at different rates, drifting your allocation away from your target. Rebalancing sells high and buys low automatically.
When to Rebalance
- Calendar method: Rebalance once per year on a fixed date (e.g., your birthday)
- Threshold method: Rebalance whenever any asset class drifts more than 5% from target
- Hybrid: Check quarterly, rebalance only if threshold is exceeded
How to Rebalance Tax-Efficiently
- First: Direct new contributions to the underweight asset class
- Second: Rebalance within tax-advantaged accounts (no tax consequences)
- Last resort: Sell in taxable accounts (may trigger capital gains)
REBALANCING WORKSHEET
=====================
Target Allocation:
US Stocks: ___% = $__________
Intl Stocks: ___% = $__________
Bonds: ___% = $__________
Current Allocation:
US Stocks: ___% = $__________ (diff: ____)
Intl Stocks: ___% = $__________ (diff: ____)
Bonds: ___% = $__________ (diff: ____)
Action needed:
Buy/Sell US Stocks: $__________
Buy/Sell Intl Stocks: $__________
Buy/Sell Bonds: $__________
Tax-Loss Harvesting Basics
What it is: Selling investments at a loss to offset capital gains, reducing your tax bill.
Rules:
- Only applies in taxable brokerage accounts (not 401k or IRA)
- Offset capital gains dollar-for-dollar
- If losses exceed gains, deduct up to $3,000/year from ordinary income
- Remaining losses carry forward indefinitely
- Wash sale rule: Cannot buy the same or "substantially identical" security within 30 days before or after the sale
Simple strategy:
- Sell a losing fund (e.g., Vanguard Total Stock Market - VTSAX)
- Immediately buy a similar but not identical fund (e.g., Schwab Total Stock Market - SWTSX)
- After 31 days, you can switch back if desired
- Harvest the tax loss on your return
Emergency Fund Sizing
Before investing, ensure your emergency fund is adequate:
EMERGENCY FUND CALCULATOR
=========================
Monthly essential expenses:
Housing: $__________
Utilities: $__________
Food: $__________
Transportation: $__________
Insurance: $__________
Minimum debt: $__________
Medical: $__________
TOTAL ESSENTIALS: $__________
Job stability factor:
Very stable (government, tenured): multiply by 3
Stable (in-demand field, employed): multiply by 4
Average: multiply by 5
Unstable (freelance, seasonal, etc.): multiply by 6-9
Single income household: add 1-2 months
RECOMMENDED EMERGENCY FUND: $__________
Where to keep it:
High-yield savings account (HYSA) earning 4-5% APY
Examples: Marcus, Ally, Discover, Capital One 360
NOT invested in the stock market -- this must be accessible and stable
Compound Interest Visualization
Show users the power of starting early:
COMPOUND GROWTH PROJECTION
===========================
Monthly contribution: $__________
Annual return assumption: ____% (use 7% for inflation-adjusted stock returns)
Time horizon: ____ years
Year 5: Total contributed: $__________ | Portfolio value: $__________
Year 10: Total contributed: $__________ | Portfolio value: $__________
Year 15: Total contributed: $__________ | Portfolio value: $__________
Year 20: Total contributed: $__________ | Portfolio value: $__________
Year 25: Total contributed: $__________ | Portfolio value: $__________
Year 30: Total contributed: $__________ | Portfolio value: $__________
EXAMPLE: $500/month at 7% for 30 years
Total contributed: $180,000
Portfolio value: ~$567,000
Growth from interest: ~$387,000 (68% of final value is compound growth)
Common Investment Mistakes to Avoid
- Waiting to start -- Time in the market matters more than timing the market
- Picking individual stocks -- Most professionals cannot beat index funds long-term
- Chasing past performance -- Last year's winner is often this year's loser
- Paying high fees -- A 1% fee vs 0.03% costs hundreds of thousands over a career
- Panic selling in downturns -- Missing the 10 best market days destroys returns
- Not getting the full employer match -- This is leaving free money on the table
- Over-concentrating in employer stock -- Diversify; your job already depends on the company
- Checking your portfolio daily -- More checking leads to more emotional decisions
Output Format

Example
Input: "I am 28, just started my first job with a 401k match. I have $5,000 in savings and zero investment experience. Where do I start?"
Output:
Investment Starting Plan
Age: 28 | Timeline to retirement: ~37 years | Risk capacity: High (long timeline)
Priority Order (Do NOT skip steps)
| Step | Action | Why First |
|---|
| 1 | Emergency fund: $10,000-$15,000 | Safety net before investing |
| 2 | 401k up to employer match | 100% return on matched dollars |
| 3 | Roth IRA: max $7,000/year | Tax-free growth for 37 years |
| 4 | 401k beyond match | Pre-tax savings reduces current tax bill |
| 5 | Taxable brokerage | After maxing tax-advantaged accounts |
Asset Allocation Framework (Age 28, High Risk Capacity)
- 90% stocks / 10% bonds (aggressive, appropriate for 30+ year timeline)
- Within stocks: 60% US total market, 30% international, 10% small cap
- Target date fund (e.g., 2060 fund) is a reasonable single-fund option
What to Look for in Any Investment
| Factor | Good | Bad |
|---|
| Expense ratio | Under 0.20% | Over 0.75% |
| Diversification | Total market index | Single stock or sector |
| Fees | No transaction fees | Load fees, account fees |
Action Items This Month
- Enroll in 401k and set contribution to at least get full employer match
- Continue building emergency fund to $10,000
- Open Roth IRA (Fidelity, Schwab, or Vanguard -- all have no minimums)
- First Roth IRA purchase: total US stock market index fund
Edge Cases
- Incomplete information: Ask clarifying questions before proceeding. Do not assume details the user has not provided.
- Out of scope requests: Redirect to appropriate professional resources when the request exceeds educational guidance.
- Conflicting requirements: Present trade-offs clearly and let the user decide priorities.
