  • Kiddos Capital Plan Generator — Outcome Projection Methodology:  The figures in a Kiddos plan are illustrative estimates, not predictions. To test whether a plan is likely to reach its goal, we simulate 10,000 possible market histories built from actual S&P 500 total returns since 1970, and run each family’s own contributions, loan, and fees through every one. A plan’s contribution is set so that it reaches the goal even in lower-outcome scenarios — by design, in roughly 9 of 10 of these simulated histories. Any “simulated return” shown is simply the steady annual rate that would produce that result for that specific plan; it is not a forecast of market returns. Past performance does not guarantee future results. For more on our methodology, please contact us. [R-Meth]
  • Tax-loss harvesting. Estimates of the added annual return from systematic tax-loss harvesting draw on Liberman, Sialm, Sosner, et al., “The Tax Benefits of Separating Alpha from Beta” (2019), which found net annual benefit in the range of roughly 0.85%–1.10%. (Link)  [R-TLH]
  • Active funds vs. the index. The finding that the large majority of actively managed funds underperform the index over long periods comes from S&P Dow Jones Indices, SPIVA U.S. Scorecard, Year-End 2024: 89.5% of actively managed U.S. large-cap funds trailed the S&P 500 over 15 years. (Link) [R-SPIVA]
  • Historic 529 Performance. To substantiate the 529 returns cited on this site, Kiddos Capital reviewed published since-inception performance for index-based target-enrollment (target-date) portfolios that have completed, or nearly completed, the full ~18-year glide path. Among low-cost, index-based plans — the most common choice — completed-cycle portfolios have returned roughly 4.7% to 5.0% per year since inception, net of fees. Representative figures:
    • New Hampshire UNIQUE Plan — NH Portfolio 2024 (Fidelity), inception 12/27/2004: 5.04% since inception (as of 03/31/2025). (Link)
    • Virginia Invest529 — Target Enrollment 2024: 4.69% since inception (as of 09/30/2026). (Link)

These portfolios hold a child’s savings from near birth to near college enrollment. By the enrollment window they have shifted largely into bonds and cash (the NH 2024 portfolio held roughly 85% bonds and short-term reserves and about 15% stocks), which is why their long-run return is well below the stock market’s historical average. Actively managed 529 plans have returned more over the same period, at higher cost and risk.

  • How a 529 glide path shifts over time. A 529 target-date portfolio typically starts heavily in stocks and moves toward conservative holdings as college approaches, ending near 10%–20% in stocks at enrollment. Representative allocations are published in each plan’s program description (for example, the Virginia Invest529 and Fidelity plans cited above).  [R-GLIDE]
  • Net price of college by family income. Figures for what families actually pay after grants and scholarships are drawn from the U.S. Department of Education’s IPEDS database (National Center for Education Statistics). For families with income above $110,000, the average net price at a public four-year university is about $85,000 over four years, and about $163,000 at a private nonprofit four-year university.

  • Why selling in a downturn matters. A family paying tuition from an investment account has to sell on the college’s schedule, not the market’s. We reviewed the last 30 years of S&P 500 history against the twice-a-year windows when tuition bills typically come due. In 10 of the last 60 of those payment windows, there was no day on which a family could have sold without taking a loss of 15% or more from the market’s recent high — and those windows clustered into two multi-year stretches (2001–2003 and 2008–2010). The point isn’t that markets don’t recover; they do. It’s that dollars sold at the bottom to pay a bill never participate in the recovery. (Based on S&P 500 price-index history, 1992–2025.
