The $72 Billion Problem, Why So Much Pension Money Sits Forgotten

Our estimate is at least $72 billion for people who moved between the UK, US and Australia (method: The Uncounted 2026, recomputed 15 October 2026), and that is a floor. Most pension systems publish no figure for lost pensions at all. Tens of billions of dollars sit in pension funds, superannuation accounts, and retirement schemes, belonging to people who have either forgotten it exists or cannot figure out how to access it.

This is the worldwide problem of forgotten pension money, and it affects people in every developed country.

The Scale of the Problem

In the UK alone, the Pensions Policy Institute estimates there are around 3 million pots lost, worth at least £18.7 billion (Lost Pensions 2026, a lower-bound estimate). In Australia, the ATO reports A$21.2 billion in lost and ATO-held superannuation as at 30 June 2026. Canada, Ireland, South Africa, Singapore, Hong Kong, New Zealand, the UAE, every country with a pension system has the same problem.

Why Does This Happen?

The answer is surprisingly simple: pension systems were designed for people who stay in one country, work for one employer, and never move house. That describes almost nobody in the modern workforce.

The job-changing problem. Workers change jobs over a career. In the UK, auto-enrolment can create separate pots where a worker qualifies and remains enrolled. GOV.UK sets out the conditions. Over a career you might have several scattered pots, each too small to feel important.

The moving house problem. Pension providers communicate by post. When you move house and forget to update your address with every single pension provider, they lose contact with you. Your pot gets flagged as "gone away" and joins the around 3 million others (Pensions Policy Institute, Lost Pensions 2026, October 2026).

The DigiD problem. This one specifically affects expats who worked in the Netherlands. To check your Dutch pension online, you need a DigiD, a digital identity that is only available to people with a Dutch BSN and a Dutch address. If you have left the Netherlands, you cannot get a DigiD. Your pension exists, but the system actively prevents you from checking it. PensionHunter does not require DigiD because we use an authorised request pack for the pension funds, prepared for you to send. Our guide explains how to check your Dutch pension without DigiD, step by step.

The auto-enrolment problem. Since 2012, UK employers have had to enrol qualifying workers. A worker had to be 22 or over, under UK State Pension age, earn at least 10,000 pounds a year and ordinarily work in the UK. Employers could postpone enrolment for up to three months. An opt-out within the first month returned payments; leaving later usually keeps payments in the pension until retirement. Short-term jobs and internships do not automatically create pots. Source: GOV.UK. Our post on auto-enrolment and forgotten pension pots goes through it.

The cross-border problem. This is where the problem grows. Many people have worked in multiple countries during their careers. Each country has its own pension system, its own registry, its own rules. There is no global pension dashboard. No way to see all your entitlements in one place. Until now.

What Can You Do About It?

First, acknowledge the problem exists. If you have changed jobs more than twice, moved house, or worked abroad, you may have pension money you have lost track of.

Second, check. You can use government services like the UK Pension Tracing Service (free but limited), or services like PensionHunter that search all 41 countries. Our free pension check shows which countries may hold a pension in your name. Our step by step guide to finding a lost pension lists each step.

Third, act. Pension money does not expire, but pension providers can demutualize, merge, or change terms. The sooner you locate your entitlements, the sooner you can make informed decisions about your retirement savings.

Check your pension probability, free. It takes 60 seconds and tells you how likely it is that you have forgotten pension money waiting for you.

The $72 billion problem is not going away, and that figure counts only the few systems that publish one. But your share of it does not have to stay forgotten. (See methodology and data sources for our per-country attribution.)
