The whole pile of business rules, in one place. Each rule states its logic in plain English, declares whether
it's sourced or a flagged guess,
and links the public evidence behind it. The weights are editorial — so edit them. Your weighting travels with
your share link.
Originwhere and to whom you were born
Country of residenceSOURCED
×2.4 · 0 to +24
Residence sets a baseline from its World Bank income tier. High-income country → high base; low-income or conflict-affected → low base.
World Bank — country income classifications. Economies grouped high / upper-middle / lower-middle / low income by GNI per capita; used here as the baseline tier. source ↗(accessed 2026-06-11)
Why this weight: The largest single predictor of lifetime outcomes is where you live — World Bank income tiers span a ~60× range in GNI per capita, dwarfing every behavioral lever in this book. 2.4× the baseline is, if anything, conservative.
weight 24 (×2.4)
Generational supportSPECULATIVE
×1.6 · 0 to +16
A family financial floor raises your position. No clean public dataset maps this to an individual, so the weight is a flagged guess, not a measurement.
Opportunity Insights (Chetty et al.) — intergenerational mobility. Documents how parental resources shape adult outcomes — real at population scale, but NOT directly operationalizable into a personal number. Hence speculative. source ↗(accessed 2026-06-11)
Why this weight: Chetty's mobility work shows parental resources rival education's effect on adult outcomes — but because no dataset maps it to an individual, this flagged guess is weighted at 1.6×, below country, above everything behavioral.
weight 16 (×1.6)
Parental educationSOURCED
×0.8 · 0 to +8
Children of degree-holding parents are far likelier to earn degrees themselves and start with more navigational capital. You didn't choose this.
NCES — First-Generation Students. College enrollment and completion rates are substantially higher for students whose parents hold bachelor's degrees than for first-generation students. source ↗(accessed 2026-06-11)
Why this weight: First-generation status roughly halves college-completion odds (NCES), but part of its effect routes through the education rule — weighted down to 0.8× to avoid double-counting.
weight 8 (×0.8)
Passport strengthSOURCED
×0.6 · 0 to +6
Your passport determines visa-free access to work, study, and flee. Derived from your country of residence in this model.
Henley Passport Index. Ranks passports by visa-free destination count; the gap between the strongest and weakest passports exceeds 160 destinations. source ↗(accessed 2026-06-11)
Why this weight: Binding only at borders and mostly latent day-to-day — 0.6× despite the huge Henley spread, because the option value is rarely exercised.
weight 6 (×0.6)
Neighborhood opportunitySOURCED
×0.8 · 0 to +8
The census tract you grew up in measurably shifts adult income. Self-assessed band here (low / average / high opportunity area).
Opportunity Atlas (Chetty, Friedman, Hendren). Children who grow up in high-upward-mobility tracts earn substantially more as adults, holding parental income constant. source ↗(accessed 2026-06-11)
Why this weight: Opportunity Atlas tract effects are causal but smaller than country-level differences — 0.8×, tied with parental education.
weight 8 (×0.8)
Health / actuarialhow a life insurer prices you
Age & sex vs. the life tableSOURCED
×1.0 · 0 to +10
Insurers price you off remaining life expectancy: younger means more runway, and women outlive men by ~5 years on average. Pure actuarial position — no virtue involved.
Social Security Administration — Actuarial Life Table. Period life tables give remaining life expectancy by exact age and sex; US female life expectancy at birth runs ~5 years above male. source ↗(accessed 2026-06-11)
Why this weight: Actuarial position is priced exactly as legibly as income by the insurance industry — weighted equal to the baseline at 1.0×.
weight 10 (×1.0)
Smoking statusSOURCEDCONTROLLABLE
×1.0 · 0 to +10
The single largest behavioral mortality factor insurers price. Never-smokers score full; former smokers recover most of it; current smokers score zero here.
CDC — Tobacco-Related Mortality. Cigarette smoking reduces life expectancy by at least 10 years; quitting before 40 recovers nearly all of it. source ↗(accessed 2026-06-11)
Why this weight: A ~10-year life-expectancy swing (CDC) — the single largest behavioral mortality factor, weighted equal to the baseline at 1.0×.
weight 10 (×1.0)
Physical activitySOURCEDCONTROLLABLE
×0.8 · 0 to +8
Scored against the 150-minutes-per-week guideline; saturates there — this model gives no extra credit for marathon volume.
WHO — Physical Activity Guidelines. Adults should do 150–300 minutes of moderate aerobic activity weekly; meeting it is associated with 20–30% reduced all-cause mortality. source ↗(accessed 2026-06-11)
Why this weight: Meeting the WHO guideline associates with 20–30% lower all-cause mortality — large, but smaller than smoking's swing, so 0.8×.
weight 8 (×0.8)
Alcohol useSOURCEDCONTROLLABLE
×0.6 · 0 to +6
Heavy drinking carries large measured mortality and financial costs; moderate use a smaller penalty; none scores full.
NIAAA — Alcohol Facts and Statistics. Excessive alcohol use is a leading preventable cause of death in the US, responsible for roughly 178,000 deaths per year. source ↗(accessed 2026-06-11)
Why this weight: Heavy use is a leading preventable cause of death, but the population-level swing is smaller than smoking or inactivity — 0.6×.
weight 6 (×0.6)
Sleep durationSOURCEDCONTROLLABLE
×0.6 · 0 to +6
7–9 hours scores full; 6 or 10 hours partial; outside that, the short-sleep mortality association bites.
CDC / AASM — How Much Sleep Do I Need?. Adults need 7 or more hours per night; short sleep is associated with obesity, diabetes, and cardiovascular disease. source ↗(accessed 2026-06-11)
Why this weight: The 7–9h association is consistent but partly confounded with everything else on this page — 0.6×.
weight 6 (×0.6)
Health insurance coverageSOURCEDCONTROLLABLE
×0.8 · 0 to +8
Being uninsured is both a health risk and the most common path to catastrophic financial shock. Controllable only to the degree coverage is affordable where you live — flagged in the description.
KFF — Key Facts about the Uninsured Population. Uninsured adults are far more likely to delay or forgo care and to carry medical debt; medical debt is a leading driver of US bankruptcy. source ↗(accessed 2026-06-11)
Why this weight: Coverage removes an uncapped financial tail risk (medical debt is a leading bankruptcy driver) — 0.8×.
weight 8 (×0.8)
BMI bandSOURCEDCONTROLLABLE
×0.6 · 0 to +6
Insurers still price by BMI band, so it appears here — scored as they score it, not as an endorsement of the measure.
Caveat: BMI is a blunt population statistic: it misclassifies muscular builds and ignores fat distribution. It is included because underwriters use it, not because it is good.
CDC — About Adult BMI. BMI bands (under 18.5 / 18.5–24.9 / 25–29.9 / 30+) correlate with metabolic-disease risk at population scale; CDC notes it is a screening tool, not a diagnostic. source ↗(accessed 2026-06-11)
Why this weight: Underwriters genuinely price it, but the measure itself is blunt (see caveat) — weighted at 0.6× accordingly.
weight 6 (×0.6)
Finance / credithow lenders and bureaus score you
Net-worth positionSOURCED
×1.6 · -8 to +∞
Net worth against the median for your age band. Below the median: a linear drag, floored at half this weight. Above it, points grow as the square root of your wealth multiple — quadruple your money to double your points — uncapped, because the real world does not cap the advantage of money.
Federal Reserve — Survey of Consumer Finances (2022). Median net worth runs ~$39k for households under 35, rising to ~$410k for 65–74 — comparing a 27-year-old to a 60-year-old is meaningless. source ↗(accessed 2026-06-11)
Why this weight: Stock beats flow: wealth absorbs shocks income cannot, and SCF gaps between wealth deciles exceed income gaps — 1.6× the baseline, uncapped above because the world does not cap it.
weight 16 (×1.6)
Debt load (DTI, not raw $)SOURCEDCONTROLLABLE
×1.4 · -14 to +14
Debt scored as leverage against income, benchmarked to the lending world's ~43% affordability line. Zero debt scores best; the same asset bought on a loan drags here.
CFPB — Ability-to-Repay / Qualified Mortgage rule. The long-standing affordability benchmark caps total debt-to-income at 43%. Lenders judge the ratio, not the sticker price of what you bought. source ↗(accessed 2026-06-11)
Why this weight: The lending world's primary gate (the CFPB 43% line) — 1.4×. The only symmetric rule in the book: the cited system punishes exactly as hard as it rewards.
weight 14 (×1.4)
Payment historySOURCEDCONTROLLABLE
×1.2 · 0 to +12
The single heaviest input in FICO's published model (35%). One late payment costs most of it; multiple zero it out.
myFICO — What's in my FICO Scores?. Payment history accounts for about 35% of a FICO score — the largest single component. source ↗(accessed 2026-06-11)
Why this weight: 35% of FICO — the heaviest input in the most consequential consumer score — 1.2×.
weight 12 (×1.2)
Credit utilizationSOURCEDCONTROLLABLE
×1.0 · -3 to +10
Share of available revolving credit in use — 30% of FICO. Under ~10% is ideal; over 30% starts costing; near-maxed goes negative.
myFICO / Experian — credit utilization guidance. Amounts owed are ~30% of a FICO score; commonly cited guidance keeps utilization below 30%, with top scorers in single digits. source ↗(accessed 2026-06-11)
Why this weight: 30% of FICO, just behind payment history — 1.0×. Mildly subtractive at near-maxed because the bureaus genuinely reprice that downward.
weight 10 (×1.0)
Emergency fundSOURCEDCONTROLLABLE
×1.0 · 0 to +10
Months of expenses covered by liquid savings, scored against the standard 3-month test. Saturates at 3 — this measures shock absorption, not hoarding.
Federal Reserve — Survey of Household Economics and Decisionmaking (SHED). A large share of US adults could not cover three months of expenses with savings; many could not cover a $400 emergency in cash. source ↗(accessed 2026-06-11)
Why this weight: The Fed's own resilience test: the 3-month line is what separates a setback from a spiral — 1.0×.
weight 10 (×1.0)
Income vs. medianSOURCEDCONTROLLABLE
×1.0 · 0 to +∞
Annual income against the US full-time median: half marks at the median, then points grow as the square root of your income multiple, uncapped — see the net-worth rule for why.
BLS — Usual Weekly Earnings of Wage and Salary Workers. Median usual weekly earnings of full-time workers, annualized, run near $60,000. source ↗(accessed 2026-06-11)
Why this weight: THE BASELINE (1.0×). Income is the dimension every other system prices most legibly; every other weight in this book is a stated deviation from this one.
weight 10 (×1.0)
HomeownershipSOURCEDCONTROLLABLE
×0.6 · 0 to +6
Owning is the dominant US wealth-building vehicle — and gatekept by everything above. Renters get partial credit; this measures system position, not virtue.
Federal Reserve SCF — homeowner vs. renter net worth. Median homeowner net worth (~$400k) is roughly 40× median renter net worth (~$10k) in the 2022 SCF. source ↗(accessed 2026-06-11)
Why this weight: The wealth effect is already counted in net worth; this 0.6× prices only the access premium to the main US wealth escalator.
weight 6 (×0.6)
Banked statusSOURCEDCONTROLLABLE
×0.6 · 0 to +6
No bank account means check-cashing fees, money orders, and no credit-building rail — a measured tax on being poor. Underbanked (account, but relying on payday/check-cashing services) pays part of it.
FDIC — National Survey of Unbanked and Underbanked Households. Millions of US households lack any bank account; unbanked households pay fees for basic transactions that banked households get free, and cannot build credit history from ordinary payments. source ↗(accessed 2026-06-12)
Why this weight: The FDIC's measured poverty premium — fees where wealth earns interest — at 0.6× the baseline, kept low because its dollar magnitude is small even though its direction is vicious.
weight 6 (×0.6)
Education / workhow the labor market values you
Education ladderSOURCEDCONTROLLABLE
×1.2 · -2 to +12
The labor market prices each rung: no diploma is actively penalized (unemployment runs roughly twice the bachelor's-holder rate), each step up narrows the gap, and the graduate premium over a bachelor's is field-dependent — so this rule caps at the bachelor's rung. 'Controllable' only if the time and tuition were affordable to you.
BLS — Education pays. Median earnings rise and unemployment falls with every rung of attainment; workers without a high-school diploma face roughly double the unemployment rate of bachelor's holders. source ↗(accessed 2026-06-12)
Why this weight: A ~60% earnings premium compounding over a working life — 1.2× the baseline. The negative floor exists because the market genuinely penalizes no-diploma, not merely fails to reward it.
weight 12 (×1.2)
Employment statusSOURCEDCONTROLLABLE
×0.8 · 0 to +8
Employed or self-employed scores full; students and retirees partial (different life phase, not failure); unemployed zero — which is how every lender reads it.
BLS — Labor Force Statistics (CPS). Unemployment correlates with sharp income loss and scarring effects on future earnings, especially for long spells. source ↗(accessed 2026-06-11)
Why this weight: The income flow is already counted by the baseline rule; this 0.8× prices the status gate every lender and landlord reads first.
weight 8 (×0.8)
Occupation outlookSOURCEDCONTROLLABLE
×0.6 · 0 to +6
Whether your field is projected to grow or shrink — BLS publishes ten-year projections for every occupation. Self-assessed band here.
BLS — Occupational Outlook Handbook. Projects employment change by occupation over a 10-year window; growth varies from double-digit increases to steep declines. source ↗(accessed 2026-06-11)
Why this weight: Ten-year BLS projections are directional, not destiny — 0.6×.
weight 6 (×0.6)
Socialconnection, record, and footprint
Social connectionSOURCEDCONTROLLABLE
×1.0 · 0 to +10
Regular contact with people you are close to. The mortality effect of isolation rivals smoking in meta-analysis — the most underpriced rule in this book.
Holt-Lunstad et al. — Social Relationships and Mortality Risk (meta-analysis). Stronger social relationships associated with ~50% increased odds of survival — an effect comparable to quitting smoking. source ↗(accessed 2026-06-11)
Why this weight: Holt-Lunstad's ~50% survival effect rivals smoking cessation — weighted equal to the baseline and to smoking at 1.0×, the most underpriced rule in the book.
weight 10 (×1.0)
Partnership statusSOURCEDCONTROLLABLE
×0.6 · 0 to +6
Married/partnered people show better longevity and household finances in the data — partly pooling, partly selection.
Caveat: Selection effects are real: healthier, wealthier people marry more. The data cannot fully separate cause from sorting, and single is not a deficit — this scores the system, not you.
Harvard Health / NIH — marriage and longevity research. Married adults show lower mortality and cardiovascular risk in large cohorts, with effect sizes that shrink after controlling for selection. source ↗(accessed 2026-06-11)
Why this weight: The longevity association is real but heavily selection-confounded (see caveat) — discounted to 0.6×.
weight 6 (×0.6)
Volunteering / communitySOURCEDCONTROLLABLE
×0.4 · 0 to +4
Regular volunteering correlates with health and well-being outcomes — and is the closest thing to a real-world "social karma" ledger.
AmeriCorps — Health Benefits of Volunteering. Volunteers report better health and lower depression; older volunteers show reduced mortality in longitudinal studies. source ↗(accessed 2026-06-11)
Why this weight: The smallest sourced effect in the book — 0.4×, the floor for sourced rules.
weight 4 (×0.4)
Driving recordSOURCEDCONTROLLABLE
×0.6 · -1 to +6
At-fault accidents and moving violations in the last 3 years, scored the way an auto insurer rates you. Clean record full; each incident bites.
Insurance Information Institute — What determines the price of an auto insurance policy?. Driving record is a primary rating factor; accidents and violations raise premiums for 3–5 years. source ↗(accessed 2026-06-11)
Why this weight: Insurer-priced with a 3–5 year decay — 0.6×. Mildly subtractive because license points literally subtract.
weight 6 (×0.6)
Digital footprintSPECULATIVECONTROLLABLE
×0.4 · 0 to +4
Employers and landlords screen public profiles, but no public dataset quantifies the effect on outcomes — so the weight is a flagged guess.
CareerBuilder — social media screening survey (2018). Majorities of employers report screening candidates online and rejecting some on what they find — survey evidence, not an outcome dataset. Hence speculative. source ↗(accessed 2026-06-11)
Why this weight: Survey evidence only, no outcome dataset — speculative, so pinned to the 0.4× floor.
weight 4 (×0.4)
Housing stabilitySOURCED
×1.2 · -6 to +12
Where you sleep is the gateway condition for everything else scored here. Stable housing scores full; doubled-up or eviction-threatened partial; unhoused subtracts — because the systems above (credit, employment, health) all actively punish it.
Caveat: Marked not-controllable deliberately: eviction research shows housing loss precedes and causes the poverty that follows it — people rarely choose their way into or out of it. Its place in the 'your moves' tier reflects where existing systems file it, not fault.
Eviction Lab (Desmond et al.). Eviction causes job loss, depression, and long-run instability — Milwaukee cohort studies show eviction precedes, not merely follows, deepened poverty. source ↗(accessed 2026-06-12)
Why this weight: Eviction sits upstream of job loss, credit destruction, and health collapse — weighted with education at 1.2×. The negative floor qualifies under the subtractive principle: every cited system actively punishes housing loss.
weight 12 (×1.2)
Civic / legalhow institutional ledgers read you
Criminal recordSOURCED
×0.8 · 0 to +8
A record roughly halves employer callbacks in audit studies. Scored as the labor market scores it — which is exactly the kind of opaque penalty this app exists to expose.
Caveat: Enforcement and conviction rates are themselves racially and economically skewed, so this rule inherits that bias from the system it measures. Shown because the penalty is real, not because it is just.
Pager — The Mark of a Criminal Record (audit study). Matched-pair audits found a criminal record cut employer callbacks by ~50%, with effects compounding across race. source ↗(accessed 2026-06-11)
Why this weight: The callback-halving effect is enormous, but the measure is binary and inherits enforcement bias (see caveat) — held to 0.8× rather than weighted like the gate it really is.
weight 8 (×0.8)
Voter registrationSPECULATIVECONTROLLABLE
×0.4 · 0 to +4
Registered voters appear in civic data used by campaigns, jury pools, and some tenant screens; the personal-outcome effect is unquantified — flagged guess.
US Census — Voting and Registration tables. Registration rates are tracked demographically, but no public dataset ties individual registration to life outcomes. Hence speculative. source ↗(accessed 2026-06-11)
Why this weight: No outcome dataset ties registration to personal results — speculative, 0.4× floor.
