Boomer Money Advice Is Out of Date. Here's the Arithmetic.

Boomer money advice is not merely dated. It is wrong, in the specific sense that following it today produces worse outcomes than ignoring it. The rules it describes were repealed by arithmetic somewhere around the turn of the century, and nobody told the people still handing it out.

We built a joke about this. Boomer-ai is free, looks like a computer from 1995, and answers any modern problem with outdated opinions, a confident reference to what houses used to cost, and a dad joke. This post is the part underneath the joke: three pieces of advice you have almost certainly been given, checked against the official numbers, all three failing.

"Just buy a house"

The Office for National Statistics measures affordability as the median house price in an area divided by the median annual earnings of a full-time worker there. Anything up to five times earnings counts as affordable.

In 1997, the average home in England and Wales cost three to four times an average full-time salary, and 88% of areas came in under the threshold.

In 2025, England's ratio is 7.6: a median price of £300,000 against median earnings of £39,300. Wales is 6.0. The share of areas under the threshold has fallen from 88% to 7%.

So the instruction has not become harder to follow. It has become impossible to follow in 93% of the country, measured by the government's own test. That is not advice. It is a description of a country that stopped existing while its residents were still giving directions.

"Just buy a house" was a reasonable instruction in a market where 88% of areas were affordable. In one where 7% are, it is noise.

"Save harder"

This is the one that deserves the least patience, because we can show exactly how little work it does.

Affordability peaked in 2021 and has improved every year since. Since that peak, median house prices are up 5% while average earnings are up 25%. Earnings ran five times faster than prices, for four straight years. England's 7.6 is the lowest ratio since 2015.

That is the best run the numbers have had in over a decade. And at the end of it, 93% of areas still fail the affordability test.

Sit with that. Four consecutive years of things moving the right way, at a pace nobody would have predicted, and the gap barely narrowed. "Save harder" asks an individual to out-run, through personal effort, a gap that four years of favourable national conditions could not close. It is not encouragement. It is a way of relocating a structural problem onto the person least able to fix it, and it is the reason so many competent people believe they are financially incompetent.

"We had it worse, rates were double digits"

This one at least has a real number behind it, and it is worth taking seriously before taking it apart.

It is true. Through 1983 the Bank of England's Bank Rate sat at roughly 9% to 11%. Today it is 3.75%, held there on 17 September on a 6 to 3 vote, with CPI inflation at 3.1% in August. Borrowing was genuinely punishing. Nor is the path from here settled: three of those nine votes were for a rise to 4%, and the next decision lands on 5 November.

But look at what kind of problem each one is.

A high interest rate is a cost you carry while you own the asset. You are already in. It hurts, it can be refinanced, and your wages rise against a debt whose size is fixed the day you sign.

A high price relative to earnings is a wall you face before you own anything. There is no refinancing your way over a deposit. Nothing about it improves by waiting, because the thing you are saving towards moves with the market you are trying to enter.

A punishing rate is a cost you pay as an owner. A punishing price is a barrier you face as an outsider. Only one of them lets you start.

"We had it worse" compares a hard thing that ended to a hard thing that hasn't started. It is the single most common piece of boomer money advice and it is a category error, which is exactly why it feels so infuriating to be on the receiving end of.

What Moola deliberately does not do

We are not going to replace one confident wrong number with another.

We do not tell you the number you need. There is a version of this product that prints "you need £68,000 and 6.5 years" and we have chosen not to build it, because that figure is a guess wearing a suit, and it makes people feel worse without making them better informed.

We also will not pretend that planning fixes a price. It does not. No financial plan makes a house cost five times your salary. What planning does is show you honestly which levers actually move your timeline and which ones are rounding errors that people fixate on because they are the only things within reach.

And the joke app has a line it will not cross. Type something into Boomer-ai that reads like genuine distress and it drops the character and shows you real UK support resources instead. A comedy generator that keeps doing the bit at someone having a bad night is not funny. It is just badly built.

Go and argue with one

Boomer-ai is free, there is no sign-up, and nothing it says is financial advice, which puts it roughly level with the original.

It runs in any browser, and as of this week it is an Android app on Google Play as well. Android only for now.

Ask it about your rent. Ask it what a pint should cost. Ask it whether you should just buy a house.

Then come back and look at 7.6, which is the number the joke is standing on.
