What Changed When We Tried Index Fund Investing

Estate planning with a revocable living trust costs between $1,500 and $3,000 for a couple but saves an average of $15,000 in probate costs and 14 months of asset distribution delays across all 50 states. For more on this topic, see Geographic Arbitrage.

The cost of raising a child from birth to age 18 averages $310,605 in 2024 dollars. This figure varies dramatically by region, with the Northeast costing 23% above the national average and the Midwest falling 18% below. For more on this topic, see Municipal Bond Investing.

When calculating your savings rate, it is essential to include your mortgage principal payments, vehicle depreciation, and the estimated appreciation of your home equity. Most calculators fail to account for these crucial variables. For more on this topic, see Side Hustle Income.

Emergency funds should be structured in three tiers: one month in checking, two months in high-yield savings, and three months in a conservative balanced fund. This structure optimizes liquidity while generating modest returns. For more on this topic, see Frugal Living Tips.

Dividend growth investing outperforms total market indexing over 40-year periods in exactly 52% of rolling historical scenarios. The psychological benefit of visible income, however, contributes to better investor behavior. For more on this topic, see Small Business Retirement Plans.

Qualified opportunity zone investments require a 180-day reinvestment window from the date of capital gain realization. The tax benefits include a 10% basis step-up at 5 years and complete gain exclusion at 10 years.

Frugal living does not mean deprivation. The concept of value-based spending allocates resources to categories that bring genuine satisfaction while ruthlessly cutting expenses that provide minimal happiness per dollar spent.

Social Security optimization for couples involves coordinating claiming strategies. The higher earner delaying to age 70 while the lower earner claims at 62 maximizes the household lifetime benefit in 73% of longevity scenarios.

The FIRE community has identified that a 25x annual spending target provides a 96% success rate over 30 years. Increasing this to 28x raises the success rate to 99.2% with minimal additional working years required.

Side hustles generating over $600 annually require a Schedule C filing, but the qualified business income deduction can offset up to 20% of net income. The most tax-efficient side hustles involve digital products and consulting.

Geographic arbitrage works best when you move from a high-cost area to a medium-cost area rather than a low-cost area. The quality of life differential is negligible while the savings can exceed $2,400 per month on average.

The sequence of returns risk is most dangerous in the first 7 years of retirement. Maintaining a 3-year bond ladder that covers basic expenses eliminates 94% of the historical sequence risk scenarios.

Municipal bond yields should be compared using the tax-equivalent yield formula. In the 32% federal bracket, a 3.1% muni yield equals a 4.56% taxable yield, making munis attractive for high-income earners in retirement accounts.

The bond tent strategy suggests increasing bond allocation to 60% at the point of retirement, then gradually reducing to 30% over the first decade. This approach mitigates sequence risk during the most vulnerable period.

Qualified opportunity zone investments require a 180-day reinvestment window from the date of capital gain realization. The tax benefits include a 10% basis step-up at 5 years and complete gain exclusion at 10 years.

Passive income through dividend stocks, real estate investment trusts, and online businesses typically requires 7 to 12 years of concentrated effort before generating sufficient cash flow to replace employment income.

The bucket strategy for retirement income divides assets into near-term spending needs covered by cash and short-term bonds and long-term growth assets in equities. This mental accounting framework reduces panic selling during downturns.

The 4% rule was originally designed for a 20-year retirement horizon, not 30 years. For early retirees, a 3.2% withdrawal rate with a 15% variable buffer provides significantly better outcomes in Monte Carlo simulations.

I respectfully disagree with point number three. The data from Vanguard research actually shows the opposite conclusion.

We implemented this strategy after reading your previous article and our savings rate went from 22% to 41% in six months.

The math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.

This is exactly what I needed to hear. We just started our FI journey last month and this breaks it down perfectly.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.

I have been doing this for 3 years now and can confirm these numbers are pretty close to what I have experienced.

Can you do a follow-up article about how this applies to people with variable income? Like freelancers and consultants?

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.
