Is 2026 finally making the coffee maths add up?

The value of your investments and the income you receive from them can go up and down, and you may get back less than you invest. Any examples are for illustration purposes only. ISA eligibility and tax rules apply.

I came across my first chalkboard menu of £5 coffees this week. The café regulars will have seen this coming for a while but witnessing it in person still felt like a watershed moment. Admittedly, the venue was achingly cool, centrally based and each cup came with a rich tale of bean to brew. Was it worth it? No idea, I couldn’t stomach the spend.

It made me think of the personal finance articles over the years that have tried to divert our money away from the coffee coffers and into our stocks & shares ISAs. A noble message, certainly - who can argue with illustrating the power of investing small’n’often and trying to make investing tax efficiently less daunting or punishing on the pocket?

The £19,343 ISA earlybird bonus

Stop believing these five ISA myths

The £2,220 ISA mistake: are you making it?

The problem is that the angle has, at times, felt a bit finger-waggy. It often assumes the UK (especially its cohort of young people) is happy to swap financial security for life’s fleeting luxuries. Takeaways, subscriptions and any amount of brunch items usually get the blame.

The main victim does tend to be coffee though, and the amount we apparently fritter away on it instead of buying houses. The clapback is often that the salary-to-house-price ratio is now so large that young people’s elastic limit has snapped and giving up said coffee wouldn’t make the slightest bit of difference.

Would it, though? Does the era of the especially expensive pick-me-up change the savings equation or is it all still a bit of a superficial soundbite?

Before we look at whether giving up our daily flat white could actually help us onto the housing ladder, and in an effort to be as factual and non-finger-waggy as possible, there are a few background factors worth knowing.

1. Coffee’s got expensive, hasn’t it?

Weather disruptions have meant the wholesale price of coffee is up over 130% over the past five years and more than tripled from 2019 lows up to the tailend of 2025. That’s a big jump in anyone’s book and is one factor behind why the little daily luxury isn’t quite so little anymore.

2. Inflation has affected everything

Headline inflation has spiked since Covid, meaning the pounds in our pocket aren’t going as far as they did during the decade after the financial crisis.

It’s not just coffee, inflation makes everything feel more expensive

It’s important we remember that the up-down here doesn’t mean products and services are now getting cheaper - rather their prices are still rising, just more slowly than they did in 2022.

That might not matter so much if our wages were rising in tandem, to offset these price rises. Sadly, that hasn’t happened. Between 2021 and 2023, inflation spiked faster than wages, essentially meaning our purchasing power dropped. More recently, with inflation easing, real wage growth has turned positive but it’s still modest and a lot of UK earners will be seeing their earnings stagnate. That’s before we add in the effect of frozen tax thresholds, which mean more UK workers will step into higher tax bands if their salaries do grow.

3. House prices

Then there are the houses a lot of the articles say our caffeine-free selves could buy. All UK regions have seen a rise in house prices over the past 10 years with the likes of Northern Ireland and the North West of England seeing growth well above that of London, albeit with the capital starting at a much higher level.

It all means that, depending on where you live, you could be shelling out anywhere between 4.8x and 11.1x the average national salary in order to afford the average house price in different parts of the UK. For perspective, the average house cost around 7x the average salary by the end of 2025, 6x in 2015, around 6x in 2005 and under 3x in 1995 [1]. Even with the spike in the late 90s and drop after the financial crisis, the overall move has been upwards.

So, relatively speaking, house affordability has been falling while coffee has got more expensive, wage growth has ebbed and flowed and inflation has put pressure on our overall spending.

Let’s work it out. For our example, we’ll say our London coffee drinker likes a daily flat white, which costs £4.25. (£5 isn’t ubiquitous just yet, thankfully, and most high street cafés tend to offer a milky drink around this price.) We’ll also say they stop by 253 times in a year on their way to work. This means they’ll spend £20.68 each week on average.

After five years they’d be thoroughly caffeinated but down £5,377. Do it for 10 years and they’d have spent £10,754, shelling out £16,130 after 15 years.

Contrast those figures with what they might have achieved if they’d ditched the java and invested their cash in a stocks & shares ISA instead. With an annual average return of 7% in line with the S&P 500’s history, after five years they’d hypothetically have £6,383, after 10 years they’d have £15,335 and after 15 years they’d have £27,889. Handily, their gains wouldn’t attract UK capital gains tax or UK dividend tax thanks to the tax efficiencies that come with a stocks & shares ISA.

These are big sums but far short of the £55,400 you’d need for a 10% deposit on a London property today. What if they were trying to squirrel away money at the same time, though? If our sipper-turned-investor had not only invested their coffee cash in their stocks & shares ISA but also combined it with the same again (giving a total weekly contribution of £41.36) they could end up with £55,779 after 15 years - hitting that deposit goal. The goalposts are likely to shift over 15 years in terms of what that deposit looks like but the example illustrates the point - we’re now at a stage where even the small luxuries aren’t that cheap, and just considering their worth and how they fit into our overall financial health is important.

There’s a temptation to let the maths take over completely and end our article there. After all, it’s not wrong to conclude that a shop-bought coffee is now so expensive that buying one every day has the potential to derail some long-term savings plans. The world isn’t just maths, though, and this is sometimes where these case studies can lose their way.

You need to make your money work for you, both in terms of how you save and invest it, and how you spend it. If you can factor in that latte on the way to work and still strive towards your financial goals, fire away. If, on the other hand, you’re concerned about your budget and haven’t noticed the steady uptick in costs, maybe this will come in handy. The point is that it’s not a one-size-fits-all journey and we shouldn’t feel browbeaten if we are already fully aware of the problem and are doing something about it.

Tips to tackling ISA volatility

My 10 key reminders for ISA investors

The new tax change you probably missed

A clear takeaway for me isn’t actually about the coffee at all, it’s the need to make the most of our savings, however much we choose to put away. Investing takes us out of cash and onto the risk ladder of the stock market but history shows us the markets have the potential to help our money grow when we give our investments time to compound. Investing in a stocks & shares ISA has the added benefit of helping us keep more of any growth we achieve by not subjecting it to UK investment taxes.

On that note, maybe the biggest idea to come out of this is to make your ISA investments meaningful. I’ve been guilty of sleepwalking into new phone contracts and renewed software subscriptions (I’m still no better at Photoshop) when I could be getting rid of what I don’t use and feeling better about my financial health by channelling my money into a long-term account designed to help me build wealth and hit my goals.

So, this isn’t scaremongering, nor is it a scroll-stopping self-help guide. Rather it’s a call to check in with your spending, your saving, your investing and your financial goals. If you haven’t done it for a while, the balance might be out of whack because of price changes happening in the background. That £5 coffee offered a stark wake-up call for me to do the same and I didn’t even need to drink it.
