Value Averaging Won the Lost Decade by $264K. It Quietly Demanded a $75K Single Month to Deliver.
Edleson's Value Averaging always hits the target. The honest question is what it costs you to get there. We ran six real historical windows — Lost Decade, Post-GFC Bull, dotcom crash — through the calculator. VA's edge is real. So is its $75K-month cash drag.
$50K Projected Flip Profit Becomes $6,400 Real: the 5 Costs Rookies Underestimate
Marcus's $280K-buy / $375K-sell flip looked like a 17% gross margin. After loan interest, holding costs, agent commission, and short-term capital gains tax, real profit was $6,400. 11.4% annualized, beat by an index fund with no effort.
Whole Life vs Buy-Term-and-Invest: $383K vs $95K at Year 20
The same $8K/year, two different paths. Whole life delivers $95K cash value at year 20; term + index fund delivers $500K death benefit + $383K portfolio. The unbundling premium is real.
$350K Rental Property: −$7K Year 1 Cash Flow, 8.2% Year-10 IRR
Jake's $350K rental at $2,100/month: 3.65% cap rate, −7.7% cash-on-cash year 1, $594/month negative cash flow for 4 years. Year-10 IRR of 8.2% is the only metric that justified holding through it.
'Pay $60K, Get $100K' Is a 2.6% IRR. Here's Why.
Insurance brochures advertise the headline gain. Run the same numbers as IRR — accounting for the fact that you paid in over 20 years, not all on day 1 — and the return drops to bond-fund territory.
What $100/Month Becomes After 10, 20, and 30 Years (and Why $50 Beats $200 Started Late)
$100/month feels too small to bother with. But run it through 30 years of compounding and the number lands at $122K. Plus the harder lesson: starting at 25 with $100 beats starting at 35 with $200.
$50K Invested at 30: What's Actually There at 60
Lump sum $50K at 7% turns into $381K in 30 years. Add $500/month and it hits $988K. But inflation cuts that nominal $988K down to $406K of real purchasing power. Both numbers matter.
Dollar-Cost Averaging: Costs ~2% Expected Return, Buys Real Behavioral Insurance
DCA loses to lump sum on expected return by about 1-2% over 10 years. That gap is the price of insurance against panic-selling — and for many investors it's worth paying.
90% of Pros Lose to the Index. The Math Is Unkind to Stock Pickers.
Over 15 years, ~88% of US active funds underperform their benchmark (SPIVA 2023). Individual stock pickers do worse. Here's why, and the small carve-out where stock picking still makes sense.
Real Returns: Why Your 7% Is Actually 4% (and What That Costs)
Brokerage statements show nominal returns. Grocery stores charge real prices. The gap between the two compounds over 30 years into hundreds of thousands of missing dollars. Here's how to read your account honestly.
$30K Student Loans at 5%: Why Minimums + Invest Beats Aggressive Payoff (Barely)
Spreadsheet says invest the extra $300 wins by $3K over 10 years. Real life says it depends entirely on whether you actually invest the savings every month, and what the market does in your specific decade.
$500/Month Invested Becomes $1,500/Month in Dividends — but Year 30, Not Year 5
The dividend snowball is real, but slow. Year 5 generates ~$100/month in dividends; year 30 generates ~$1,500/month. Most of the magic happens in years 20-30, which is why most people give up before it starts.
Pay Off Debt or Invest? The Spread Decides — and the Spread Behaves Differently in Each Direction
If your loan rate is 7% and expected investment return is 10%, investing wins on paper. But the loan return is guaranteed and the investment return isn't. Here's where that asymmetry tips the math.
Opportunity Cost Without the Guilt Trip
Every dollar you spend has a second price: the future value you didn't keep. Here's how to use that frame for big decisions, and ignore it for the small ones.
How Compound Interest Actually Works (Stop Quoting Einstein)
Compound interest is just earning returns on returns. The math is simple. The reason it's powerful — and the reason most people get it wrong — is that the curve barely moves for the first 10 years.
$50K Bonus: Lump Sum Beats DCA 67% of the Time (the Other 33% Is the Story)
Vanguard's research and our Monte Carlo runs converge on the same answer: lump sum wins about two-thirds of the time. The interesting question is what happens in the third where DCA wins, and whether you'd survive it.
