The Household Quality-of-Life Economic Gradient (HQLEG) is a proposed way to measure the economic capacity left over after a household pays what it must pay — and how much room that leaves for saving, building, and living.
Household economic status is usually described through income brackets — lower, middle, upper-middle, high. But income only describes what enters a household. It says nothing about what a household is required to spend to keep functioning.
Consider two households that each earn $60,000 a year.
Both households have identical income. They do not have the same economic condition — and the gap only widens further up the income scale, where housing, health care, childcare, and debt obligations can vary enormously between two households earning the same paycheck.
After a household pays for food, shelter, transportation, health care, insurance, and required debt — how much economic capacity remains to save, invest, improve quality of life, and help others?
HQLEG starts with income and subtracts what a household is required to spend, arriving at what actually remains.
Essential Life Costs and Required Debt are tracked separately on purpose. A $600 grocery bill and a $600 credit-card payment are not the same kind of burden — one is current consumption, the other is an obligation created by the household's existing financial structure. HQLEG measures both, but never conflates them.
| After-Tax Income | Costs + Debt | Remaining | Surplus Rate |
|---|---|---|---|
| $40,000 | $38,000 | $2,000 | 5% |
| $60,000 | $51,000 | $9,000 | 15% |
| $80,000 | $60,000 | $20,000 | 25% |
| $100,000 | $65,000 | $35,000 | 35% |
| $100,000 | $50,000 | $50,000 | 50% |
Two households earning exactly $100,000 land 15 points apart on surplus rate, purely because of what they owe and what they must spend. That gap is what HQLEG is built to measure.
Rather than sorting households into broad labels like "poor" or "middle class" — labels that can conceal enormous differences in actual circumstance — HQLEG proposes a continuous score based on surplus rate.
| Score | Economic Condition | Surplus Capacity |
|---|---|---|
| 0–10 | Economic Deficit | Negative / zero |
| 11–20 | Survival | 0–10% |
| 21–30 | Severe Constraint | 10–15% |
| 31–40 | Constrained | 15–20% |
| 41–50 | Marginal Stability | 20–25% |
| 51–60 | Stable | 25–30% |
| 61–70 | Financially Secure | 30–40% |
| 71–80 | Strong Economic Capacity | 40–50% |
| 81–90 | High Economic Freedom | 50–65% |
| 91–100 | Exceptional Surplus Capacity | 65%+ |
These thresholds are working assumptions designed to begin testing the concept. They are not scientifically validated or officially adopted, and they may change as the methodology is evaluated against real household data.
Importantly: a household's score describes an economic condition, not its worth. A low score does not imply a lack of effort, and a high score does not imply greater merit.
Version 1.0's calculator below focuses on the core surplus math. The complete HQLEG framework is intended to eventually capture five dimensions of household economic life.
How much of usable income is consumed by housing, food, utilities, transportation, clothing, health care, insurance, communications, and childcare.
How much income is committed to credit cards, auto loans, student loans, personal loans, medical debt, and other recurring obligations — tracked separately from balance owed.
The core surplus calculation: dollar surplus, percentage surplus, and — just as important — how consistent that surplus is month to month.
How much of the surplus can realistically convert into emergency savings, retirement, investment, education, or a business.
What's left to improve daily life, support family, and help others — recognizing that economic surplus creates agency beyond the absence of poverty.
A household can have money left over and still be financially fragile. HQLEG eventually distinguishes several kinds of surplus.
Money remaining after current obligations — before accounting for reserves or debt exposure.
Remaining money for a household that already holds reasonable emergency reserves and stable footing.
Money that can reasonably be directed toward long-term wealth-building.
Money available to improve daily life beyond basic maintenance — recreation, travel, skills.
Resources available to help family, friends, or community.
Version 1.1 splits essential costs into universal and conditional tiers, and adds a reserves check so the result reflects more than income flow alone. Nothing you enter here is stored, saved, or sent anywhere.
Costs nearly every household carries regardless of circumstance.
Only counted toward your surplus if they apply to your household — check the box if it does.
Used only to check whether surplus is a cushion or already spoken for.
"Surplus Position" (renamed from "Score" in v1.1) maps your surplus rate onto the provisional 0–100 gradient above. It's always shown next to the dollar surplus and rate it's built from — it isn't meant to stand alone, and it describes an economic condition, not a household's worth. Buffer status is separate: it checks reserves against essential costs, not income.
HQLEG doesn't claim to be the first attempt at measuring financial well-being. It's an attempt to combine several existing, related concepts into one framework aimed specifically at surplus, future-building capacity, and quality of life.
Related measures already in use include disposable income, consumer expenditure surveys, debt-service ratios, savings rates, and poverty thresholds. The Federal Reserve's Survey of Household Economics and Decisionmaking already asks whether people have money left over at month's end, and the Consumer Financial Protection Bureau maintains a Financial Well-Being Scale. HQLEG's proposed contribution is the specific structure of the gradient — combining surplus, future-building capacity, quality-of-life capacity, and social contribution capacity into a single, continuous score.
Future versions of HQLEG will attempt to incorporate real household data from the Federal Reserve, Bureau of Labor Statistics, Census Bureau, CFPB, HUD, USDA, and Bureau of Economic Analysis. Here's what we want to learn.
The credibility of this project comes from its willingness to correct itself. Nothing here changes silently.
Four changes made in response to early critique of v1.0:
The founding release of HQLEG: usable income minus essential life costs minus required debt equals household surplus, mapped onto a provisional 0–100 gradient.
Future releases will appear here as Version 1.1, 1.2, 2.0, and so on, each with what changed and why.
