Belgian general government devoted 14.787% of its total expenditure to the health function in 2024 — roughly one euro in every seven euros of government spending.
Using Belgium’s current official 2024 GDP of €619.914 billion and the published general-government expenditure ratio of 54.1% of GDP, that corresponds to approximately €49.6 billion.
The €49.6 billion figure is a Cameralius derivation, because the 54.1%-of-GDP expenditure ratio used in the calculation is rounded. The controlling statistical observation is the official COFOG result: health = 14.787% of total Belgian general-government expenditure.
That figure does not mean that INAMI/RIZIV had a €49.6 billion budget. It also does not measure every public and private healthcare euro spent in Belgium.
It measures something more specific: expenditure by Belgian general government, S.13, classified under the COFOG health function GF07.
The short answer
| Measure | Belgium, 2024 |
|---|---|
| Health share of general-government expenditure | 14.787% |
| Approximate health expenditure | ≈€49.6bn |
| Approximate share of GDP | ≈8.0% |
| Statistical sector | General government, S.13 |
| Functional classification | COFOG GF07 — Health |
| Reference period | Calendar year 2024 |
| Current status | Provisional |
Health was also Belgium’s second-largest broad government spending function in the 2024 COFOG accounts, after social protection.
What exactly is being measured?
The relevant statistical dataset is Eurostat’s General government expenditure by function — gov_10a_exp.
It forms part of the ESA 2010 transmission programme and classifies general-government expenditure according to COFOG — the Classification of the Functions of Government.
The institutional perimeter is the entire general-government sector S.13.
That means the statistic is not confined to the federal government, a health ministry, INAMI/RIZIV, hospitals, social-security funds, communities and regions, or local authorities. Instead, qualifying expenditure across the whole S.13 sector is classified according to the purpose it serves.
Eurostat reports the data annually on a calendar-year basis. The current metadata explicitly mark Belgium’s 2024 functional expenditure figures as provisional.
What does the COFOG health function include?
Health is COFOG division GF07.
At the more detailed second level, the health function covers groups including:
- medical products, appliances and equipment;
- outpatient services;
- hospital services;
- public-health services;
- research and development related to health;
- health expenditure not elsewhere classified.
The classification is functional: it asks what government expenditure is for, rather than which ministry, agency or level of government happens to pay it.
That distinction is particularly important in Belgium because responsibility for healthcare does not sit neatly inside one institution.
This is government health expenditure — not every euro spent on healthcare in Belgium
COFOG government health expenditure ≠ total healthcare expenditure in the Belgian economy.
Households can pay directly for healthcare. Private insurance and other private arrangements can also finance healthcare.
There is a separate international statistical framework — the System of Health Accounts — designed specifically to analyse healthcare expenditure by financing scheme, healthcare function and provider.
That framework answers different questions from COFOG. A statistic labelled “Belgian healthcare expenditure” from another database should therefore not automatically be compared with the COFOG figure.
For this article, the question is deliberately narrower: How much expenditure did Belgian general government classify to the health function?
Why isn’t the answer simply the INAMI/RIZIV budget?
Because INAMI/RIZIV is one major institution inside a much wider healthcare-financing and government system.
For 2024, INAMI reported a global healthcare-insurance budget of more than €42.743 billion. Within that, the budget for reimbursement of healthcare services was €37.825 billion.
Those are important official numbers. But they answer different questions from the COFOG statistic.
| 2024 figure | What it describes |
|---|---|
| ≈€49.6bn | Cameralius approximation of whole-general-government COFOG health expenditure |
| €42.743bn | INAMI/RIZIV global healthcare-insurance budget |
| €37.825bn | INAMI/RIZIV budget for reimbursement of healthcare services |
These figures should not be subtracted from one another or treated as nested categories unless a proper statistical bridge establishes that relationship.
What does the INAMI/RIZIV number measure?
INAMI/RIZIV’s healthcare-insurance budget is an annual institutional budget comparing expected expenditure with expected revenue for the compulsory health-insurance system.
That makes it a budget for a particular social-insurance mechanism. It is not a functional classification of every government unit in Belgium.
Institution budget ≠ whole-government functional expenditure.
Budgeted amount ≠ ex-post national-accounts expenditure.
Healthcare reimbursement ≠ every government transaction classified to health.
Why can the general-government figure be broader?
Imagine expenditure on a public-health programme carried out by a community government, government wages associated with a qualifying health service, investment in a government health facility, or health-related research expenditure.
Those transactions may belong to the COFOG health function even though they are not simply reimbursements made through the compulsory health-insurance system.
Conversely, the accounting structure of an institutional budget does not map one-for-one onto COFOG lines.
COFOG reorganises relevant expenditure according to economic function after the underlying government transactions have been incorporated into the ESA accounts. That is why institutional budgets and functional expenditure statistics cannot safely be substituted for one another.
Nor is this the budget of a Belgian “health ministry”
Belgium’s institutional structure makes that shortcut particularly misleading.
Health-related responsibilities and financing operate across several parts of government and social security. The general-government statistic is deliberately constructed to cross those institutional boundaries.
If qualifying health expenditure occurs within central government, communities or regions, local government, or social-security funds, it can contribute to the S.13 health function according to the statistical rules.
This is why What counts as Belgian government? and What is the difference between Belgium’s federal budget and general-government finances? are foundational companions to this article.
Functional classification and institutional classification answer different questions
- How much did INAMI/RIZIV budget? That is an institutional question.
- How much did Belgian general government spend on health? That is a functional question.
- How much did households, government schemes and insurers collectively finance healthcare? That is closer to a health-accounts question.
All three questions can produce valid official statistics. Their answers do not have to match.
COFOG expenditure is also broader than cash payments made during the year
The COFOG dataset forms part of the ESA 2010 government accounts. ESA principally records transactions on an accrual basis.
The question is therefore not merely how much cash physically left government bank accounts between 1 January and 31 December. Relevant economic transactions are attributed to periods according to national-accounts rules.
Cash paid during 2024 ≠ necessarily ESA expenditure attributed to 2024.
Why use 2024 instead of 2025?
Functional government expenditure is published later than Belgium’s main deficit, debt, revenue and expenditure aggregates.
The current COFOG series runs through 2024, even though newer 2025 headline figures are already available for Belgium’s general-government revenue, expenditure, deficit and debt.
This produces another important boundary:
Latest headline fiscal year ≠ latest functional-spending year.
For the question in this article, 2024 is therefore the appropriate closed reference year.
Is €49.6 billion an official published figure?
Not in the form used here.
The directly observed statistic we rely on is:
Health = 14.787% of total Belgian general-government expenditure in 2024.
Eurostat also reports Belgium’s 2024 GDP at €619.914 billion and headline general-government expenditure at 54.1% of GDP.
Cameralius therefore calculates:
€619.914bn × 54.1% × 14.787% ≈ €49.6bn.
The same inputs imply a health-function expenditure ratio of approximately 8.0% of GDP.
Because the 54.1% expenditure ratio is rounded, €49.6 billion and 8.0% of GDP remain labelled Cameralius approximations, not independently published official COFOG values.
Why the distinction matters
It would be easy to write: “Belgium’s healthcare budget was €42.7 billion in 2024.”
That sentence would sound plausible because €42.743 billion is genuinely an official INAMI number. But it would silently change the question.
It would describe the healthcare-insurance budget of a particular institution rather than the whole Belgian general-government health function.
The correct number depends on the statistical object.
What this does not mean
- INAMI/RIZIV spent €49.6 billion.
- Belgium had a single €49.6 billion “healthcare budget”.
- The federal government alone spent that amount.
- A single Belgian health ministry controlled that amount.
- €49.6 billion measures every public and private healthcare euro spent in Belgium.
- The INAMI €42.743 billion budget can simply be deducted from the COFOG amount to reveal “other health spending”.
- The €37.825 billion reimbursement budget is equivalent to government health expenditure.
- Every euro classified to health was physically paid in cash during 2024.
- 14.787% means 14.787% of GDP.
- The 2024 COFOG figure is final.
The Cameralius rule
Before answering “How much does Belgium spend on healthcare?”, establish five things:
- Which perimeter? General government S.13, one government level, one institution, or the whole economy?
- Which classification? COFOG government function or System of Health Accounts?
- Budget or expenditure? An authorised or forecast institutional budget, or an observed national-accounts statistic?
- Which period? Calendar year 2024 in this article.
- Which vintage? The current 2024 COFOG series, presently provisional for Belgium.
With those boundaries fixed, the answer is:
Health represented 14.787% of Belgian general-government expenditure in 2024 — roughly one euro in seven. Using the currently published aggregate expenditure and GDP figures gives an approximate value of €49.6 billion, a Cameralius derivation.
That is the appropriate whole-government answer. It is not the same thing as the budget of INAMI/RIZIV.

Revision state: Belgium 2024 COFOG data currently provisional.
Cameralius derivation: €619.914bn GDP × 54.1% general-government expenditure/GDP × 14.787% health share ≈ €49.6bn. The same inputs imply ≈8.0% of GDP. Because 54.1% is rounded, both results remain approximate.
Revision note: this article is vintage-locked to the current 2024 COFOG release. If Eurostat or the National Bank materially revises Belgium’s 2024 functional expenditure, Cameralius should update the observation transparently rather than silently replacing it.
