Frequently Asked Questions About Ben Felix Evidence-Based Financial Decisions Framework
21 answers covering everything from basics to advanced usage.
// Basics
What does 'unrecoverable costs' mean in the context of buying a home?
Unrecoverable costs are money you pay while owning a home that you will never get back regardless of how the property performs. They include mortgage interest (not principal), property taxes, maintenance, emergency repairs, renovation spending, and the opportunity cost of equity locked in the home. The critical insight is that the mortgage payment itself is only one piece — summing all unrecoverable costs typically makes owning far more expensive than it initially appears when compared to renting.
What is the PERMA model in financial planning?
PERMA is a five-factor model of human flourishing from positive psychology: Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment. In the Ben Felix framework, PERMA serves as a filter on every financial goal. Before committing resources to a goal, you check whether it maps to at least one PERMA category. Goals that map to none are unlikely to produce lasting life satisfaction regardless of their financial size, and should be deprioritised or removed.
Should I get whole life insurance or term life insurance?
Term life insurance. The framework explicitly recommends term over whole life insurance. Term life is cheap and serves its purpose: replacing your human capital (future earning power) if you die while your dependants rely on your income. Whole life insurance combines investing and insurance in a single product, typically with high fees and low returns. The framework's principle of separating insurance from investing means buying cheap term life and investing the premium difference in low-cost index funds.
Does the framework account for real estate as an investment strategy?
The framework treats primary residence ownership as a consumption decision, not an investment. It does not address real estate investing (rental properties, REITs) as a separate asset class in depth. For your primary home, the 5% Rule and unrecoverable cost analysis determine whether buying is financially justified. The framework warns against treating past real estate appreciation as a reliable expectation — those returns were shaped by a specific historical environment of falling interest rates and supply constraints that may not repeat.
What does 'investing has been solved' actually mean?
It means the question of what to invest in has a definitive evidence-based answer: low-cost, broadly diversified index funds. The remaining challenges are behavioural — automating contributions, avoiding the temptation to pick stocks, not panic-selling during downturns, and not checking your portfolio too frequently. The framework positions investment selection as a solved problem to redirect attention to the genuinely hard parts: execution, goal-setting, tax planning, and managing psychology.
// How To
How do I calculate the opportunity cost of a home down payment?
Take the down payment amount and compound it at the expected equity return (roughly 7% nominal) over your investment horizon. For example, a $120,000 down payment compounded at 7% over 35 years grows to approximately $1.27 million. That is the implicit cost of locking that capital in home equity instead of the stock market. This calculation makes the true cost of home ownership visible and comparable to the rental alternative.
How do I administer the tightwad/spendthrift quiz to myself or my partner?
Answer four questions about spending scenarios: (1) Would you buy a coat on sale you don't need? (2) How do you feel splitting a restaurant bill unevenly? (3) Is your overall spending/saving balance skewed? (4) How do you feel when buying something expensive? Mostly A answers indicate tightwad (high pain of paying), mostly B is unconflicted, and mostly C is spendthrift (low pain of paying). Have both partners take it separately to identify mismatches that predict financial conflict.
How do I run the three-step goal-setting exercise from the framework?
Step one: write down all your financial goals with no filter. Step two: force yourself to double the list — add at least as many new goals as you originally wrote, even if they feel secondary. Research shows these additional goals are later rated as equally meaningful. Step three: review each PERMA category (Positive Emotion, Engagement, Relationships, Meaning, Accomplishment) and ask whether any goals belong there that you missed. Then audit each goal — remove or deprioritise any that map to zero PERMA categories.
How do I prioritise the framework's recommendations when I can't do everything at once?
The framework produces a ranked action list. Typical priority order: (1) maximise tax-advantaged accounts, (2) set up a low-cost index fund portfolio with automated contributions, (3) confirm term life and disability insurance for anyone with dependants, (4) write a will, (5) complete the PERMA goal-setting exercise, (6) run the 5% Rule on any pending rent-vs-own decision, (7) assess spending profiles if partnered. The behavioural guardrail applies throughout: look at your investments as infrequently as possible.
// Troubleshooting
What if the 5% Rule says renting is better but I really want to buy?
The 5% Rule quantifies the financial cost of buying vs. renting — it does not prohibit buying. If the rule shows buying is more expensive, you now know the exact premium you are paying for the non-financial benefits of ownership (stability, customisation, community roots). Run those benefits through the PERMA filter: if ownership maps strongly to Relationships, Meaning, or Accomplishment, paying the premium may be justified. The key is making an informed decision rather than buying based on the myth that renting is 'throwing money away.'
What if I already own a home — is the framework still useful?
Yes. Apply the framework's opportunity cost analysis to your current equity: every dollar of home equity has an implicit cost equal to what it could earn in the stock market (~7% annually). This does not mean you should sell, but it does mean you should factor this cost into decisions about paying down your mortgage faster vs. investing, renovating vs. investing, or downsizing. Also run the full 10-mistake audit — housing is only one of ten areas the framework covers.
What if my partner and I are both tightwads or both spendthrifts?
Matched spending profiles produce less marital financial conflict than mismatched ones, but they carry their own risks. Two tightwads may under-spend on experiences that map strongly to PERMA categories like Positive Emotion and Relationships. Two spendthrifts may struggle to save enough for long-term goals. The framework recommends both partners complete the PERMA goal-setting exercise to surface these blind spots and create accountability structures — automated savings for spendthrift pairs, planned experiential spending for tightwad pairs.
How do I apply the framework if I live outside Canada or the US?
The framework's core principles — index fund investing, opportunity cost analysis, PERMA goal-setting, and the 5% Rule — are jurisdiction-agnostic. What changes by country is the specific tax-advantaged accounts available (ISA in the UK, superannuation in Australia, etc.), property tax rates for the 5% Rule, and estate planning laws. Adjust the 5% Rule's components for your local property tax and maintenance costs. For tax planning specifics, the framework recommends consulting a qualified local fee-only financial planner or CPA.
How do I know if I'm taking the wrong risks vs. not enough risk?
Not enough risk means holding too much cash, under-allocating to equities, or staying on the sidelines — surrendering the ~5% annual return premium stocks have historically delivered over cash. The wrong risks mean pursuing speculative bets with negative or uncertain expected returns: individual stock picking, crypto tokens, sector funds, or covered call ETFs. The test: if your investment strategy deviates from low-cost index funds, calculate the expected-return difference and ask whether the deviation has positive expected value supported by academic evidence.
// Comparisons
How does the Ben Felix framework differ from Dave Ramsey's approach?
Dave Ramsey's approach prioritises debt elimination, emotional motivation, and conservative investing (actively managed funds with high fees). The Ben Felix framework prioritises evidence-based decisions: low-cost index funds over active management, opportunity cost quantification over debt-free psychology, and the PERMA model over emotional urgency. Ramsey recommends paying off your mortgage early; Felix would calculate the opportunity cost of accelerated payments vs. investing. Ramsey avoids all debt; Felix distinguishes between mathematically rational leverage and emotionally driven debt avoidance.
How does the Ben Felix framework compare to the FIRE (Financial Independence, Retire Early) movement?
Both share common ground on low-cost index investing and high savings rates. The key differences: FIRE often treats early retirement as the primary goal, while the Ben Felix framework subjects every goal — including early retirement — to the PERMA filter and may find it maps poorly to Engagement or Meaning. The framework also challenges extreme early-career saving via consumption smoothing research, suggesting that saving less when income is low and more when income is high produces better lifetime outcomes than the constant extreme frugality FIRE prescribes.

How does the lifecycle asset allocation research challenge conventional wisdom about bonds?
The conventional wisdom says investors should shift from stocks to bonds as they age. The lifecycle asset allocation paper — analysing data from 39 countries back to 1890 across one million simulated lifetimes — finds that 100% equities (roughly one-third domestic, two-thirds international) produces better retirement consumption and bequest outcomes. Bonds carry more inflation risk than conventionally assumed, and shifting to bonds too early sacrifices the equity risk premium during decades when compounding matters most.
Why does the framework say to check your investments as infrequently as possible?
Academic evidence shows that frequent portfolio monitoring increases perceived risk, reduces equity allocation, and produces lower long-term returns. Human brains interpret short-term volatility as danger — a survival instinct that is counterproductive for long-term investing. The more often you look, the more likely you are to see a loss, and the more likely you are to react by selling or shifting to bonds. The framework's behavioural guardrail: automate contributions, invest in index funds, and review at most quarterly.
What is a covered call ETF and why does the framework advise against it?
A covered call ETF holds stocks while selling call options on them to generate income. The framework advises against them because the income is not free — it comes at the cost of capped upside appreciation. These products have high implied costs and exploit mental accounting bias (the preference for seeing income rather than capital gains). Over time, the foregone appreciation typically exceeds the income generated, making covered call ETFs inferior to simply holding a low-cost index fund.
Is 100% equity allocation really optimal even close to retirement?
The lifecycle asset allocation paper, drawing on data from 39 countries and one million simulated lifetimes, finds that 100% equities produces better retirement outcomes than the conventional glide path toward bonds. However, this is described as 'the most controversial paper in finance.' The framework presents it as the evidence-based baseline, not a universal prescription. Investors near retirement with very low risk tolerance or specific short-term spending needs may still hold some bonds — but should do so knowing the evidence challenges that choice.
What is a bootstrap simulation in the lifecycle asset allocation research?
Bootstrap simulation is the statistical method used to test asset allocation strategies across one million hypothetical investor lifetimes. It works by randomly drawing multi-year blocks of actual historical returns from different countries and currencies, then weaving them together to create diverse simulated scenarios. This avoids relying on any single country's history and captures a wide range of possible outcomes — including scenarios far worse than any individual country has experienced. The result: 100% equities still outperforms across the full range.
