- The OECD income-band calculation needs comparable disposable income, a national median and a matching household-size adjustment.
- The worked example puts a four-person household at 120% of its hypothetical national median; it does not establish financial security.
- Six editorial questions help identify planning gaps; their points cannot diagnose financial health or social class.
- Debt-to-assets and debt-to-income are different measures. Assets can be valuable without being available for bills.
An income band answers where a household sits in a distribution. It cannot tell you whether the household can afford its bills or withstand an income interruption. This guide gives you a reproducible income calculation and a separate planning checklist. The checklist is editorial and unvalidated: it cannot certify financial security, social class or readiness to invest.
Am I middle income? Calculate your income band
The OECD’s 2019 Under Pressure report defines middle income as 75% to 200% of national median equivalised disposable household income. Its household-size adjustment divides income by the square root of the number of household members. This is a statistical convention, not a universal definition of social class. OECD, 2019.
- Find a comparable median. Use the OECD Income Distribution Database or your national statistics office. Record the income year, income definition and household-size adjustment. A median of individual salaries or gross household earnings is not interchangeable with this measure.
- Add annual household disposable income. Include relevant income from employment, self-employment, pensions, investments and cash benefits, after the applicable taxes and social contributions. Follow the statistical series’ definition rather than counting only wages.
- Adjust household size. For the square-root method, divide this total by √(household members).
- Compare like with like. Divide adjusted income by the median and multiply by 100. Use the same currency, income period and price basis. Comparing current income with an old median produces an approximation, not a precise current classification.
| Household members | Square-root divisor, rounded for display |
|---|---|
| 1 | 1.00 |
| 2 | 1.41 |
| 3 | 1.73 |
| 4 | 2.00 |
| 5 | 2.24 |
Use the exact square root in calculations, especially near a boundary. If your median uses a different equivalence scale, use that scale for your household too. Mixing adjustments can materially change the answer.
Hypothetical example, in neutral currency units. Four people have annual disposable income of 60,000. Their adjusted income is 60,000 ÷ √4 = 30,000. With a comparable national median of 25,000, their position is 30,000 ÷ 25,000 × 100 = 120%. That places them inside this middle-income band. It does not establish how much remains after housing, debt payments or care costs.
For the broad band, below 75% is lower income, 75% through 200% is middle income, and above 200% is upper income under this definition. These labels describe income position within a country; they do not rank people across countries or measure their worth.
A six-question planning checklist
Answer from recent records where possible. Each A earns 2 points, B earns 1 and C earns 0. The cutoffs and equal weights below are our editorial choices, not a regulator’s financial-health test. If an answer is unknown or not applicable, record it separately and skip the total until you have comparable answers.
1. What share of disposable income goes to housing?
Include rent or mortgage payments and essential housing bills. Use the same month or year for both numerator and denominator.
- A: 30% or less.
- B: More than 30%, up to 40%.
- C: More than 40%.
Calculation: housing of 900 against income of 3,000 is 30%. The remaining 2,100 still has to cover every other commitment. A percentage alone cannot show affordability. The OECD housing database uses a 40% overburden threshold but distinguishes narrow and broader housing-cost measures. Our all-in checklist is not an exact reproduction of every official series. OECD HC1.2 methodology.
2. Could you meet a surprise bill equal to one month’s disposable income?
- A: From accessible savings without reallocating money already needed for planned essentials.
- B: From accessible savings, but only by changing planned spending or saving.
- C: Not without new borrowing, help from others or selling non-cash assets.
A credit limit is borrowing capacity, not savings. Keep this scenario distinct from actual insurance coverage or a known upcoming expense.
3. How long would accessible savings cover essential costs if the main income stopped?
- A: At least three months.
- B: At least one month, but less than three.
- C: Less than one month.
Calculation: accessible savings of 4,800 ÷ essential monthly costs of 1,600 = three months. Do not count the same cash twice for a surprise bill and a separate reserve. Record likely replacement income or public benefits separately, with eligibility and timing checked. The recession stress test explores these assumptions.
For context, the OECD/INFE 2023 survey reported country/economy averages of 54% able to meet a one-month-income expense without borrowing or family help, and 43% able to cover at least three months after losing their main income. These are averages across participating places, not a population-weighted global percentage or validation of our checklist. OECD/INFE 2023, pp. 8 and 51.
4. What happens to the monthly balance?
- A: Income exceeds spending, and the surplus is saved or invested.
- B: Roughly breaks even.
- C: Spending usually exceeds income, reducing savings or adding debt.
Check several months and include irregular annual bills. One surplus month does not prove a sustainable surplus. Cash flow basics explains the calculation.
5. How much debt sits against your assets?
Include debts and assets consistently, using reasonable current estimates rather than purchase prices.
- A: No debt, or debt below 50% of positive asset value.
- B: Debt from 50% through 75% of positive asset value.
- C: Debt above 75%, or positive debt with no assets.
These are editorial leverage bands, not an OECD diagnosis of over-indebtedness. In the report’s Figure 4.11, over-indebtedness is measured as debt greater than three times annual household income; that is a different ratio. OECD, 2019, Figure 4.11.
If assets are zero, do not divide by zero. No debt and no assets scores A under the explicit no-debt option, but says nothing about available cash. A home or pension may be valuable but unavailable for today’s bill. Also review repayments, interest terms and possible asset-price falls. Net worth is a snapshot, not a spending plan.
6. Have you checked retirement, healthcare and education commitments?
For each relevant area, ask whether you have compared expected needs with reliable resources and understood the main gaps.
- A: All relevant areas checked, with identified gaps addressed in a feasible plan.
- B: Some checked, but gaps or assumptions remain.
- C: None checked, or major gaps have no plan yet.
Include public pensions, public healthcare, workplace benefits and other support where applicable. Private saving is not the only form of provision, and education borrowing does not automatically imply insecurity. Feeling reassured is not a substitute for checking eligibility, exclusions and out-of-pocket costs.
How to use the total
| Points | What the answers show |
|---|---|
| 10–12 | More answers aligned with the checklist’s chosen buffer and planning assumptions. |
| 6–9 | A mixture of answers; review the individual items rather than relying on the total. |
| 0–5 | Fewer answers aligned with those assumptions; choose one concrete gap to investigate. |
The total cannot measure financial health, predict shock survival or decide whether you are middle class. Someone can earn 120% of the median and have little accessible cash. Someone outside the band can have manageable bills and reliable public support. Keep the income result and the planning answers separate.
Start with a specific unresolved item rather than trying to improve the number itself. Build a reserve in stages using the emergency fund guide and savings goal calculator. Review repayment amounts and due dates in your cash flow, and use retirement planning basics for longer-term assumptions.
