The Cost of Raising a child in Belgium: Real Numbers That Will Surprise You

In Belgium, the saying goes that a child costs you a house. AG Insurance and the Gezinsbond put a number on it: €264,310 over 25 years, or €917 per month when childcare and study costs are included. The Belgian median house price in Q3 2024 was €275,000. Headlines wrote themselves. VRT’s Money Time podcast ran with it, and the Gezinsbond has been publishing versions of this research for years.

The problem is that the number is largely fiction.

I mean, it’s not a lie, exactly. The method used exists and was used for courts in the past. But €917/month is what a child costs if you assume a specific kind of parent: someone who buys everything new, never uses Vinted or other secondhand platforms, pays above-average childcare rates, sends their kid to university with a student room, and gets no child allowance, somehow (every parent, regardless of income, gets this). That parent doesn’t really exist.

Most Belgian families in 2026 shop secondhand, use the inkomenstarief, and receive €184+ per child per month from the groeipakket. When you actually look at the numbers that way, the picture is very different.

So here is the version I actually wanted when my wife and I were figuring this out: real numbers, from a real family, in Belgium, in 2026. What is the real cost of raising a child in Belgium, and why is the headline figure so far from reality? Here is our answer.

We have two kids. Our daughter just turned five. Our son was born in April 2026. Here is what they cost us per month.

TL;DR: The Numbers Up Front

For anyone who wants the bottom line before the context:

Two kids add about €344 net per month to our combined monthly costs. The AG Insurance figure of €917 is per child. Below I go in detail why the gap is that large.

Why the €917 Figure Is Not Your Budget Number

Where the Number Comes From

The AG Insurance calculation is based on the Renard formula: a Belgian method originally designed to calculate child maintenance payments in divorce cases. It has been the standard for decades. The problem is that it has serious critics, and many Flemish family court judges have quietly moved away from it in recent years. The reasons:

• It uses outdated statistics
• Works with broad averages instead of actual household costs
• It was never built to reflect how real families spend money day to day.

Before the actual numbers, it helps to understand what is baked into that €917. Because once you see it, the gap makes a lot more sense.

It Assumes You Never Shop Secondhand

The Renard formula works by taking a percentage of household income and attributing it to the child. If a family earns X, they spend Y on their child. That ignores how efficiently parents actually shop. On top of that, the formula’s data is decades old, compiled before Vinted, Facebook Marketplace, or any large-scale sharing platform existed.

When those tables were built, buying secondhand was something you did because you had to. Now it’s a deliberate choice across all income levels. Research from the Gezinsbond shows that 73% of Belgian parents buy at least part of their baby kit secondhand, saving an average of €750 and up to €1,800 for patient shoppers. For clothing, 44% of families with children under 9 buy secondhand as their default. The formula still prices everything at full retail.

It Charges Part of Your House to the Child

This is probably the biggest distortion. The Renard formula attributes a proportional share of all household spending to the child, including housing, utilities, and the car. But most families would have bought roughly the same house and car regardless. The real extra costs of having a child are food, diapers, clothing, and childcare. When you isolate that, you end up somewhere very different from €917.

What the Calculation Conveniently Skips

On top of the formula problems, the AG figure has a few specific omissions:

No child allowance. AG Insurance states this explicitly. For a two-child family receiving €368/month, that is roughly €110,000 over 25 years, not deducted from the total. The €917/month is gross, not net.

Above-average childcare costs. The Gezinsbond used €30/day as the assumed childcare cost. Families on the inkomenstarief pay less, sometimes well below €10/day for lower incomes. We pay €23.83/day.

A kotstudent. The education costs assume university plus student accommodation away from home. Plenty of Belgian students commute and live at home for a fraction of that.

And last but certainly not least: an insurer wrote it. The AG press release moves straight from the €264,310 figure to pitching tak-21 savings insurance, tak-23 funds, and their Yongo savings plan.

What Belgium’s Own Data Actually Shows

The Gezinsbond publishes a more granular set of figures: a monthly cost breakdown by age and income level, with kinderbijslag already deducted. At the Belgian average income of €3,825/month, the net monthly cost for a child aged 1 to 5 is €462. The average across all ages of childhood is €625/month. Both are well below the €917 headline.

StatBel’s comparison of actual spending between families with and without children tells a similar story. The real annual difference across all categories amounts to roughly €7,900/year, or about €660/month gross before child allowance. That includes housing and transport costs you’d have anyway.

The €917 is an outlier, not a consensus. The Gezinsbond’s own more detailed data contradicts it. The real cost of raising a child in Belgium, according to Belgium’s own research, is meaningfully lower.

Now, does all of this mean the people at AG are liars? In the end, it’s a model built for a specific kind of consumer: someone who buys everything new, never shops around, and spends in full proportion to their income. Most, if not all, Belgian parents in 2026 are not that person.

Your number depends on your income, your region, your childcare situation, and how you shop.

To give a real-life example, here is ours.

What Belgium Pays You First: The Groeipakket

Before the costs, because this part gets skipped too often: Belgium actually gives you money for having kids.

In Flanders, child benefits fall under the groeipakket, a support package that replaced the old kinderbijslag system in 2019. Every child gets a monthly amount; in 2026, this is around €184 per month as a guaranteed minimum. But it can go higher. On top of the basisbedrag, families can receive additional amounts depending on their situation: a sociale surcharge for lower incomes, a care surcharge for children with health issues, (until this year) a toddler surcharge for preschool attendance, and so on.

The more precarious your financial situation, the more the system adds on top of it. For us, with a decent household income, we sit close to the basisbedrag without much extra. But for families earning less, the groeipakket can be meaningfully higher. With two kids, we receive €368 per month before we have spent a single euro.

The groeipakket also includes a one-off startbedrag of around €1,300, paid out around the birth of each child regardless of birth order. It doesn’t cover everything, but it lands at exactly the right time and softens the initial hit a bit. If you want the full breakdown of those one-off costs, I covered them in my earlier post about the financial reality of having a baby in Belgium.

The Belgian system cushions the blow more than the headlines suggest. You are not starting from zero.

The Biggest Cost: How the Inkomenstarief Works in Practice

The inkomenstarief is the income-based daycare pricing system used by all recognized childcare facilities in Flanders. Instead of a fixed daily rate, you pay based on your household’s earnings. Kind en Gezin sets the brackets, and you can check your own rate via their online calculator.

Our son will go to a day care nearby, from 08:00 to 17:00 five days a week. At nine hours a day, he falls into the “5 to under 11 hours” bracket. Our daily rate is €23.83, below the €30/day figure AG Insurance used, because the inkomenstarief scales with your income rather than charging a flat market rate.

At 20 working days per month, that is €477.

A few things to know about that number:

You still pay when your child is sick. Daycare contracts in Flanders include a set number of gerechtvaardigde afwezigheidsdagen (justified absence days) per year during which you are not charged. Outside of those, the invoice keeps coming whether your child is there or not. Budget for the full amount every month.

There is a tax reduction, but not this year. Belgium offers a federal tax reduction of 45% on eligible childcare costs, up to a daily ceiling of around €15.40. For us, that works out to roughly €1,650 back per year. But it comes back via your tax return the following year, not as a monthly discount. In terms of cash flow, €477 is what leaves the account every month. So you get real money in the form of a tax benefit, but it’s just that you won’t see it for a year.

It is temporary. Once Nico reaches around two and a half years old, he moves to kindergarten, which is free. The €477/month has a built-in expiry date. Good to keep in mind when the invoices start coming in.

The sibling discount did not apply to us. There is a €3.34/day discount when you have multiple children in a proper day care simultaneously. Since our daughter is already in kindergarten, Nico is the only one in the system. I.e., no overlap, no discount.

The Smaller Costs of Raising a Child in Belgium

After daycare, here is what else actually shows up. This time I don’t have to estimate. We track everything in YNAB under a Kids category with subcategories for Sports, Clothing, Medical, Care, School, Entertainment, Food, and other material. Since our daughter was born in May 2022, that category has averaged €235 per month.

That covers everything: clothing that gets outgrown every six months, activity registrations, toys, books, school supplies, diapers during the baby phase, and the occasional GP co-payment. It does not include daycare because our daughter never went. She stayed with my parents until kindergarten, a real money saver!

A few things worth unpacking in that number

Medical is close to zero in practice. Between CM mutualiteit and our hospitalization insurance through my wife’s work, most things are covered or heavily reimbursed. Belgium’s healthcare system carries a lot of weight that never shows up in these cost comparisons.

Clothing and activities are seasonal, not monthly. Activity registration in September, a winter jacket in October, swimming kit in March. The monthly average smooths it out, but the actual spending is lumpy.

The €235 will increase now that there are two kids. This average is almost entirely based on our daughter. With Nico added, especially during the diapers-and-formula phase, expect the number to go up. We will see what it settles at over the next year or two.

The Net Monthly Cost of Raising a Child in Belgium

So what does it actually cost us per month?

About €344 per month net, in real cash terms, is what two kids add to our monthly costs right now.

It is worth being very clear about what that number represents: this is for both kids combined. The AG Insurance figure of €917/month is per child. To compare apples to apples, our gross cost per child is around €356/month, and net after kinderbijslag, it is closer to €172 per child per month. Against their €917 per child. And that is before the YNAB historical average fully reflects Nico’s costs, since daycare only just started.

The gap isn’t because our kids are unusually cheap to raise. It’s because the research layers assumption on assumption: no kinderbijslag, above-average childcare costs, proportional housing charges, kotstudent university fees, everything bought new. Strip those out and replace them with what a real Belgian family actually does, and the cost of raising a child in Belgium lands somewhere around €172 per child per month net, not €917.

That’s real money. But it’s not the catastrophe the “een kind kost een huis” framing implies. The inkomenstarief, the groeipakket, and Belgium’s healthcare do a lot of the heavy lifting. Belgium is actually a pretty decent country to have kids in, if you use the system properly.

One more thing not in the table: the €1,650 tax reduction for daycare is applied the following year via your tax return.

What This Means for a FIRE Plan

Less than I expected, honestly.

When we were expecting our second, I half-expected the FIRE timeline to shift meaningfully. €344 net per month is about €4,130 per year. That’s real, and it does affect the compound maths over time. But it’s not a plan-killer. The daycare bill is temporary. The groeipakket offsets more than people realise. And between my freelance income and my wife’s salary, we have enough room to absorb it without changing direction.

If anything, writing out these numbers made me less anxious, not more. Vague dread is almost always worse than the actual figure.

If you’re in Belgium and trying to work out what kids do to a FIRE plan: run the Kind en Gezin calculator with your own income, factor in the groeipakket, and look at the net. The cost of raising a child in Belgium is more manageable than you expected — and it shouldn’t stop you fro
