The Financial Shock of Having Children After 40

I had twenty years to prepare financially for this. I had a pension, a property, savings, an ISA, and a reasonably systematic approach to all of them. I had spent my thirties being considerably more organised about money than most people I knew.

I still wasn't prepared.

Not because I hadn't done the calculations. I had done the calculations — I am a software engineer, calculating things is practically recreational. I knew what childcare cost in our area. I knew what the additional household costs looked like. I had modelled it. The model was correct.

What I had not modelled was the emotional weight of the numbers, which turns out to be different from the numbers themselves.

The childcare calculation

Full-time nursery in our part of the Home Counties currently costs approximately £1,500 per month per child. This is a number that bears reading again: fifteen hundred pounds. Per month. Per child.

We had two children within two years, which meant there was a period — about eight months — when we were paying full nursery fees for both simultaneously. That is three thousand pounds per month, before tax, which is money that leaves the account with the cheerful regularity of a direct debit but the emotional impact of a small bereavement.

I knew this was coming. I had the savings to cover it. It still felt wrong in a way I had not anticipated — not catastrophic, not unmanageable, but persistently dissonant. Money I had spent twenty years saving was now leaving at speed, and the thing it was buying, while entirely worth buying, produced no asset, no equity, no return on a spreadsheet. It simply enabled Claire and me to work, which enabled us to pay for the thing that enabled us to work.

I found myself describing this to a friend as "the childcare paradox" and he looked at me with the gentle pity of a man who had done this at 30 with a lower salary and no savings and had just not thought about it in those terms.

He is right that it is mostly a framing problem. But framing problems are real problems.

What the pension spreadsheet looks like now

Here is the specific version of this that older parents face and that no one warned me about clearly.

At 40, my pension projections looked reasonable. Not spectacular — I had been self-employed for stretches, which is not kind to pension contributions — but reasonable. Enough to retire somewhere in the normal range.

At 40, with a newborn, the pension projections looked different, because the time available to compound those projections was now ten years shorter than it had been in my mental model of "when I'll retire." I had vaguely assumed retirement around 65. With a child born when I was 40, I would be 65 when Ellie was 25. Plausible. With Sam, I would be 65 when he was 23. Also plausible, but starting to involve him still potentially being in some form of education or early career when I was meant to be winding down.

Then there's the university calculation. Ellie will be university age when I am 58. Sam when I am 60. These coincide with the final approach to retirement. I could well be in a position of simultaneously reducing my working income and being asked to help fund someone's tuition and accommodation.

This is not a disaster. It is a timing problem. But timing problems compound.

What I actually changed

Life insurance. I should have sorted this in my early thirties and didn't, because I had no dependents and couldn't be bothered. I sorted it when Ellie was three months old, by which point I was 40 and the premium was meaningfully higher than it would have been at 35. The lesson for anyone reading this who is at the "trying" stage rather than the "arrived" stage: do this now. The difference between a 35-year-old's premium and a 42-year-old's premium on a decent level-term policy is not trivial.

Pension contributions. I increased them. This felt counterintuitive when cash was tight with the nursery fees, but the maths of pension contributions is relentless in its rewards for consistency, and the tax relief is real money. I used the childcare fee reductions (the free hours came in at three, then the funded hours at four) as the trigger to route what had been going to nursery into the pension instead. Not all of it — life is not only a spreadsheet — but a meaningful portion.

YNAB. This is a budgeting app. I am aware this is not a glamorous recommendation. I was resistant to it because I thought I already knew where the money was going. I did not, entirely, know where the money was going. YNAB forced me to be specific, which forced me to make choices rather than simply observe the account balance trending in the wrong direction. I have used it every month for the last three years. It is the closest thing I have found to a financial nervous system. (There is a link in the Toolkit if you want to look at it.)

Emergency fund. I had one. I made it larger. Having children creates a category of financial surprise that did not previously exist — the boiler breaking the same week someone needs emergency dental treatment the same week the car fails its MOT — and the emergency fund is the buffer between a bad week and a bad month.

The thing worth saying

Money anxiety and parenting anxiety are not the same thing, but they share a frequency. Both involve projections about the future, uncertainty about variables you can't control, and the particular helplessness of having accepted a responsibility so large that it cannot be hedged away.

What I have found useful is the same thing I've found useful for the mortality calculations: do the work that is available to do, and then stop running the numbers for the day. The YNAB budget gets reviewed on Sunday evenings. The pension gets checked quarterly. The rest of the week, the numbers are someone else's problem.

You spent twenty years preparing. That counts for something. It doesn't count for everything. But it counts.
