Why This Matters
You’re here because:- 💰 You want to build wealth systematically
- 🔄 You want investing to be automatic (not dependent on discipline)
- 📈 You understand consistency beats perfection
- 😰 You don’t want to time the market
- ⏰ You value your time (don’t want to think about investing weekly)
What is Dollar-Cost Averaging (DCA)?
The Simple Definition
Dollar-Cost Averaging = Investing the same dollar amount at regular intervals, regardless of price Instead of:- Trying to “time the market” (buying when price is “right”)
- Investing lump sums irregularly
- Making emotional decisions
- Invest $X every month on the same day
- Whether market is up or down
- Automatically, without thinking
- For decades
How DCA Works
Example: Investing $500/month in VOO (S&P 500 ETF) Month 1: VOO at $400- Invest $500 → Buy 1.25 shares
- Total shares: 1.25
- Invest $500 → Buy 1.43 shares (more shares at lower price!)
- Total shares: 2.68
- Average cost per share: $373
- Invest $500 → Buy 1.32 shares
- Total shares: 4.00
- Average cost per share: $375
- Invest $500 → Buy 1.19 shares
- Total shares: 5.19
- Average cost per share: $385
- Current value: 2,000)
- Gain: $180 (9%)
- You bought more shares when price was low (month 2)
- You bought fewer shares when price was high (month 4)
- Your average cost is better than if you timed it poorly
- Works automatically without emotion
DCA vs Lump Sum vs Timing
Scenario: You have $12,000 to invest Strategy A: Lump Sum (Invest all $12k today)- Pros: Statistically best 2/3 of the time (market usually goes up)
- Cons: Maximum regret if market drops tomorrow
- Best for: Experienced investors comfortable with volatility
- Pros: Reduces timing risk, psychologically easier, smooths entry
- Cons: Might miss gains if market goes straight up
- Best for: Beginners, anyone nervous about lump sum
- Pros: None (feels smart but isn’t)
- Cons: Miss entire gains waiting, impossible to time bottom, paralysis
- Best for: No one (avoid this)
- Lump sum beats DCA 66% of the time historically
- But DCA beats market timing 95% of the time
- DCA provides better sleep for beginners (reduced regret)
The Math: How DCA Builds Millions
Example 1: The $500/Month Millionaire
Age 25, invests $500/month until age 65:- Monthly: $500
- Years: 40
- Total invested: $240,000
- At 10% annual return: $3,162,033
Example 2: The $250/Month Half-Millionaire
Age 30, invests $250/month until age 65:- Monthly: $250
- Years: 35
- Total invested: $105,000
- At 10% annual return: $886,655
Example 3: The $1,000/Month Multi-Millionaire
Age 22, invests $1,000/month until age 65:- Monthly: $1,000
- Years: 43
- Total invested: $516,000
- At 10% annual return: $7,371,490
The Power of Starting Early
Two investors, both invest $500/month: Investor A: Starts at age 25, stops at 35 (10 years)- Total invested: 500)
- At age 65 (30 years of compounding after stopping): $1,365,227
- Total invested: 500)
- At age 65: $1,019,017
Step 1: Determine Your Monthly Contribution
The 50/30/20 Rule
Allocate your after-tax income:- 50% Needs (rent, food, utilities, transportation)
- 30% Wants (entertainment, dining, hobbies)
- 20% Savings + Investing
- Needs: $2,000
- Wants: $1,200
- Savings/Investing: $800
- Emergency fund building: $300/month (until 6 months saved)
- Investing: $500/month
- After emergency fund complete: $800/month investing

Step 6: Optimization Strategies
Timing Your Contributions
Best day to invest monthly: Option 1: 1st of month- Easy to remember
- After payday for most people
- Consistent
- Ensures money is available
- “Pay yourself first” mentality
- Avoids spending it
- Middle of month
- Some people’s payday
- Alternative to 1st
- Not really. Consistency > perfection.
- Monthly on any day beats sporadic investing.
Increasing Contributions Over Time
Strategy 1: Annual Raise Rule- Every January, increase contribution by 10%
- 550/month next year
- Matches income growth typically
- Get 5% raise? Increase investing by 2.5%
- If making 4,200
- Increase investing from 550
- Lifestyle improves + Investing increases
- Start: $200/month
- Every 6 months: Increase by $50
- Year 1: 250
- Year 2: 350
- Year 5: $600/month
- Gradual increase sustainable
Tax-Advantaged Accounts First
Priority order: 1. 401(k) up to employer match- If employer matches 5%, contribute 5%
- Free money, take it first
- Example: 250/month 401k (gets $250 match)
- 583/month
- Tax-free growth forever
- After 401k match, prioritize this
- 1,917/month
- Tax-deferred growth
- If you can afford, max this
- After maxing tax-advantaged accounts
- No limits on contributions
- Set up DCA into VOO/VTI
Step 7: Monitoring Your Automated System
Monthly Check-In (5 minutes)
Review:- Did automatic transfer execute? ✓
- Did automatic investment execute? ✓
- Any errors or failures? (fix if yes)
- Total contributed this year: $____
- Current portfolio value: $____
Quarterly Deep Dive (30 minutes)
Every 3 months:- Review overall portfolio performance
- Check asset allocation (still at target?)
- Assess if contribution amount still appropriate
- Consider increasing contribution if income grew
- Ask Money Monty to analyze portfolio
Annual Review (1-2 hours)
Every January:- Calculate total contributions for year
- Calculate total gains/losses
- Rebalance portfolio back to target allocation
- Increase monthly contribution (10% increase recommended)
- Update investment policy statement if life changed
- Celebrate progress!
Common DCA Mistakes to Avoid
Mistake #1: Stopping During Market Drops
The scenario:- Market crashes 30%
- “I’ll pause investing until it recovers”
- Stop automatic contributions
- You’re buying at DISCOUNT during crashes
- Stopping means you miss the best prices
- Defeats entire purpose of DCA
- Month 1: Buy at $400
- Month 2: Market crashes, price $280 (30% off!)
- If you stop: You miss buying at $280
- If you continue: You get 43% more shares for same money!
- Never stop during crashes
- If anything, INCREASE contributions during major drops
- Buy MORE when others panic
Mistake #2: Increasing Spending Instead of Investing
The scenario:- Get 10% raise ($500/month more)
- Lifestyle inflation: Buy nicer car, bigger apartment
- Don’t increase investing
- Still investing same $500/month despite higher income
- Get 10% raise
- Invest at least 50% of raise ($250/month)
- 750/month investing
- Modest lifestyle improvement with other half
- Scenario A (don’t increase): $1,774,728
- Scenario B (increase by 2,662,092
- Difference: $887,364 from investing half of raise
Mistake #3: Trying to Time DCA
The scenario:- Automatic investment set for 1st of month
- Market feels “high” on 1st
- Cancel automatic purchase
- “I’ll wait for a dip”
- Dip never comes
- Month ends, you didn’t invest
- Repeat for 6 months
- Lost 6 months of compounding
- Set it and forget it
- Never override automatic investments
- Trust the system
Mistake #4: Not Adjusting for Life Changes
The scenario:- Set up $500/month DCA 5 years ago
- Income doubled since then
- Still investing only $500/month
- Could easily afford $1,000/month now
- Review annually
- Increase contributions as income grows
- Lifestyle creep is enemy of wealth
- Invest your raises
Mistake #5: Forgetting About It Completely
The scenario:- Set up automated investing
- Never check again
- 10 years later: Password to account forgotten
- No idea how much wealth built
- No optimization, no increases, no rebalancing
- Monthly 5-minute check
- Quarterly 30-minute review
- Annual deep dive and rebalancing
- Stay engaged without obsessing
