The Cost Of Not Knowing: why financial fluency is everyone's business

15 May 2026

By Hayley Coyne, Manager, North Hub, Money Ready

This National Numeracy Day, Money Ready are proud to stand alongside National Numeracy and shine a light on something that touches all of us – our relationship with money and the knowledge gaps that can quietly hold us back.

This year's theme, Count on Your Community, is a powerful reminder that confidence with numbers doesn't grow in isolation. It grows through support, encouragement and the people around us. And nowhere is that community support more urgently needed than when it comes to financial fluency.

Why numbers and money go hand in hand

Numeracy and financial confidence are deeply connected. You can't compare mortgage deals, read a payslip or build a savings habit without being comfortable with numbers. Yet across the UK, millions of people lack confidence in both, and it comes with a cost, quite literally.

Research from Money Ready's flagship Cost of Not Knowing campaign found that the average UK adult loses over £640 every year simply through delayed or misunderstood financial decisions. Over a lifetime, that adds up to more than £18,000 per person. This is money that could have gone towards savings, security or a brighter future.

These aren't reckless mistakes. They're the everyday costs of not having the knowledge, language or confidence to navigate a financial system that nobody taught us about, and trying to do it alone. When communities talk openly about money, share what they know and learn together, those costs can start to shrink.

What is Money Ready's Cost of Not Knowing campaign?

Launched in January 2026, the Cost of Not Knowing is Money Ready's flagship research and advocacy campaign. It's built on a nationwide survey of 3,000 UK adults and sets out, in honest, human terms, the real impact of financial education gaps.

The headline findings are striking:

  • £640+ lost per person, per year to financial confusion and indecision
  • £18,000+ lost over decades instead of supporting savings, security and opportunity
  • 35% of adults say they learned financial skills too late to make the most of them
  • 43% believe they could have saved more if they had better budgeting knowledge
  • 71% believe the government should do more to ensure people receive financial education

But this campaign isn't about blame. As Money Ready CEO Leon Ward puts it: 

"We rely on financial literacy every day, often without realising it. Yet too often, people aren't taught how the system works. We help people learn how to swim, ride a bike or drive a car, yet when it comes to navigating financial products and services, there is little or no training provided.”

The Cost of Not Knowing campaign calls on government, financial services and employers to make financial education a right, not a privilege, embedded at every life stage.
