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)
The truth: Automatic investing is the secret to wealth for regular people. Every millionaire investor either inherited money or invested consistently for decades. You can't control inheritance, but you CAN automate consistency.
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
You do:
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
Month 2: VOO drops to $350 (market down)
Invest $500 → Buy 1.43 shares (more shares at lower price!)
Total shares: 2.68
Average cost per share: $373
Month 3: VOO at $380
Invest $500 → Buy 1.32 shares
Total shares: 4.00
Average cost per share: $375
Month 4: VOO rises to $420
Invest $500 → Buy 1.19 shares
Total shares: 5.19
Average cost per share: $385
Current value: $2,180 (invested $2,000)
Gain: $180 (9%)
The magic:
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
Strategy B: DCA ($1,000/month for 12 months)
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
Strategy C: Market Timing (Wait for "dip")
Pros: None (feels smart but isn't)
Cons: Miss entire gains waiting, impossible to time bottom, paralysis
Best for: No one (avoid this)
Data:
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)
Recommendation: Use DCA for ongoing contributions (monthly investing). Use lump sum if you inherit or receive bonus.
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
You became a multi-millionaire investing $500/month.
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
Nearly a millionaire from $250/month.
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
Over $7 million from $1,000/month for 43 years.
The Power of Starting Early
Two investors, both invest $500/month:
Investor A: Starts at age 25, stops at 35 (10 years)
Total invested: $60,000 (120 months × $500)
At age 65 (30 years of compounding after stopping): $1,365,227
Investor B: Starts at age 35, continues to 65 (30 years)
Total invested: $180,000 (360 months × $500)
At age 65: $1,019,017
Investor A invested $120,000 LESS but ended with $346,210 MORE.
Starting 10 years earlier > Investing 3x more money.
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
Example: $4,000/month take-home pay
Needs: $2,000
Wants: $1,200
Savings/Investing: $800
Split the 20%:
Emergency fund building: $300/month (until 6 months saved)
Investing: $500/month
After emergency fund complete: $800/month investing
Income-Based Guidelines
Conservative (10% of gross income):
$40,000/year
$333/month
$60,000/year
$500/month
$80,000/year
$667/month
$100,000/year
$833/month
Moderate (15% of gross income):
$40,000/year
$500/month
$60,000/year
$750/month
$80,000/year
$1,000/month
$100,000/year
$1,250/month
Aggressive (20-25% of gross income):
$40,000/year
$667-833/month
$60,000/year
$1,000-1,250/month
$80,000/year
$1,333-1,667/month
$100,000/year
$1,667-2,083/month
Start Small, Increase Over Time
Don't wait until you can afford "the perfect amount"
Year 1: Start with what you can afford
$100/month if that's all you have
Build habit and confidence
Year 2: Increase by 10-20%
$100 → $120/month
As income grows or expenses decrease
Year 3-5: Keep increasing
$120 → $150 → $200
Lifestyle creep in reverse (invest raises)
Year 10: You're investing significant amounts
$200 → $500+ per month
Compounding accelerates
The key: START NOW with ANY amount, increase over time.
Step 2: Choose Your Automatic Investment Strategy
Option 1: Auto-Transfer + Auto-Invest (Full Automation)
How it works:
Bank auto-transfers $X to brokerage on 1st of month

Those adjusting allocations monthly
Active learners
Available at:
All brokerages
Option 3: Manual Everything
How it works:
You remember to transfer money monthly

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
Option 2: Day after paycheck
Ensures money is available
"Pay yourself first" mentality
Avoids spending it
Option 3: 15th of month
Middle of month
Some people's payday
Alternative to 1st
Does timing matter?
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%
$500/month → $550/month next year
Matches income growth typically
Strategy 2: Invest Half of Raises
Get 5% raise? Increase investing by 2.5%
If making $4,000/month, raise to $4,200
Increase investing from $500 to $550
Lifestyle improves + Investing increases
Strategy 3: Plateau Strategy
Start: $200/month
Every 6 months: Increase by $50
Year 1: $200 → $250
Year 2: $300 → $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: $5,000 salary → $250/month 401k (gets $250 match)
2. Max out Roth IRA
$7,000/year = $583/month
Tax-free growth forever
After 401k match, prioritize this
3. Finish maxing 401(k)
$23,000/year = $1,917/month
Tax-deferred growth
If you can afford, max this
4. Taxable brokerage
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: $____
That's it. 5 minutes per month.
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
Example quarterly review:
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
Why it's wrong:
You're buying at DISCOUNT during crashes
Stopping means you miss the best prices
Defeats entire purpose of DCA
Example:
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!
The fix:
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
What should happen:
Get 10% raise
Invest at least 50% of raise ($250/month)
$500/month → $750/month investing
Modest lifestyle improvement with other half
The result over 30 years:
Scenario A (don't increase): $1,774,728
Scenario B (increase by $250): $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
The fix:
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
The fix:
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
The fix:
Monthly 5-minute check
Quarterly 30-minute review
Annual deep dive and rebalancing
Stay engaged without obsessing
