Short answer: Review the actual contracts, fees and risks before changing your financial arrangements. Separate historical research from current prices, and personal illustrations from guaranteed outcomes. For expats, assess residence, tax, pensions and future spending currencies together.
The sources below were checked on 3 October 2026. Research from earlier years is identified by its actual period; it does not establish current provider charges or your personal results.
What does the research actually show?
Personal-finance products and consumer mistakes
In Harvard’s account published on 31 October 2025, John Campbell describes Fixed: Why Personal Finance Is Broken and How to Make It Work for Everyone, coauthored with Tarun Ramadorai and published by Princeton University Press. The account identifies Ramadorai as a professor at Imperial College London.
Campbell describes an interaction between consumers’ mistakes and financial-industry practices. He also says the course and book offer practical advice, alongside proposals for a simpler and safer system. It would be misleading to describe the authors’ position as regulation alone, or to turn this account into proof that every financial firm profits from a customer’s ignorance.
Our practical approach is to examine the particular product and decision. Ask what it costs, which problem it solves, what could go wrong, and whether you understand the alternatives.
Financial literacy: a historical survey
The S&P Global FinLit report used interviews conducted in 2014, with more than 150,000 adults in over 140 economies. Its target population was aged 15 and above, excluding prisoners and soldiers.
The test covered risk diversification, inflation, numeracy and interest compounding. A respondent was classified as financially literate by correctly understanding at least three of these four concepts. Under that definition, 33% globally qualified; the report’s country appendix gives 67% for the United Kingdom.
These results describe that survey and definition. They are not a current global literacy rate, and should not be combined with a different survey’s compound-interest result as if the samples and tests were identical.
Retirement savings: a projection rather than today’s deficit
The World Economic Forum’s release of 26 May 2017 projected a combined retirement-savings gap of USD 400 trillion by 2050 for the US, UK, Japan, Netherlands, Canada, Australia, China and India.
The study compared resources with a target of 70% of pre-retirement income, using assumptions about retirement ages, income and population. Its appendix says household debt was excluded and that individual savings held by the wealthiest 10% were excluded using inequality data. This is not a current worldwide deficit, a prediction for every country, or an amount every retiree needs to save.
Use your own pension statements and spending scenarios to plan. A large aggregate forecast does not establish that your pension will disappear.
Active funds: category and benchmark matter
As a historical example, SPIVA’s U.S. Year-End 2024 report, published on 4 March 2025, found 65% of active large-cap U.S. equity funds underperformed the S&P 500 during 2024. Its U.S. small-cap comparison was different: 30% underperformed the S&P SmallCap 600 that year.
Over the 15 years ending December 2024, the report says no studied category had a majority of active managers outperforming. These are results for defined categories, periods and benchmarks, not a universal probability that any active fund will fail. Check the applicable current report and methodology when assessing a particular claim.
Where should I look for costs?
Start with your own statements and the applicable tariff or contract. Compare the entire service, not a headline “free” account or a single fund charge.
| Area | Questions to ask |
|---|---|
| Bank account and transfers | What are the account, payment, intermediary and currency-conversion charges? How much arrives at the destination? |
| Borrowing | What are the total borrowing cost, repayment schedule, variable-rate terms and early-repayment charges? |
| Insurance | What risks, limits, exclusions, excesses and cancellation or surrender terms apply? |
| Investment account | What are the dealing, custody/platform, conversion, transfer and withdrawal charges? |
| Fund | What ongoing expenses and trading costs apply to this share class? |
| Advice | How is the adviser paid, what service is included, and what conflicts or additional product fees apply? |
The SEC’s fee bulletin dated 23 July 2025 distinguishes transaction fees from ongoing expenses and explains that fees leave less invested to earn returns. It recommends reading disclosures and asking about the full costs.
Its hypothetical USD 100,000 portfolio growing 4% annually over 20 years ends at approximately USD 208,000 with a 0.25% annual fee, compared with USD 179,000 with a 1% annual fee. These are the regulator’s assumed illustration, not projected returns for your investments.
For a transfer, obtain quotes at the same time for the same amount and route, then compare the recipient’s amount after all disclosed charges. There is no universal bank markup or provider fee that applies to every currency, plan and transaction.
What are five practical steps?
1. Set an affordable saving routine
Review your income, essential spending, debts and accessible emergency funds before setting an automatic transfer. Choose an amount you can sustain and revisit it when circumstances change. A fixed 10% or 20% target is not evidence that a plan suits every household.
Where an employer pension contribution or match applies, check the scheme’s actual eligibility, contribution and access conditions. Record benefits you are entitled to rather than assuming every employer or immigration status provides the same arrangement.
2. Understand the investment before choosing a fund or broker
The SEC explains that an index fund seeks to track a market index. It may hold all the index’s securities or a sample. Index funds can have lower management costs, but not every index fund is cheaper than every active fund.
They retain the risks of the underlying securities and can lag their index through expenses, trading costs and tracking error. Read the prospectus and key information for the actual share class. Check what it holds, its costs and whether it fits your goals; an index label does not guarantee a profit or an appropriate level of diversification.
For a broker, compare the actual agreement rather than the appearance of its app:
- The legal entity, applicable regulator and whether it accepts your residence status.
- The product and exchange available to you, and the complete current fee schedule.
- Custody, nominee and beneficial-ownership terms, segregation and the applicable client-protection arrangements.
- Transfer-out and withdrawal terms, account statements and tax information.
- Recurring-purchase costs and controls, including any conversion and trading charges.
Check those documents for Revolut, Interactive Brokers or any other provider you consider. Do not assume that one app’s custody differs from another solely because one also contains a spending account, or that a slow withdrawal prevents impulsive decisions.
3. Test retirement scenarios
Collect statements for each state, workplace and personal pension. Check projected income, retirement/access dates, indexation, fees and any survivor benefits directly with the scheme or authority.
Model several spending levels, lifespans, inflation and return assumptions. Include contingencies and identify which income is guaranteed under the actual terms. A fixed planning age of 95 or an assumed constant return is a scenario, not a prediction or universal solution.
Before transferring a pension, assess the benefits surrendered, charges, taxation and regulatory requirements. Ask for advice appropriate to the pension and jurisdictions; moving to Cyprus alone does not establish that a transfer or overseas pension scheme is advantageous.
4. Reconcile currencies and cross-border tax
List the currencies of your income, debts and expected spending, then assess the effect of adverse exchange-rate changes. Ask the provider to explain the investment’s currency exposure, underlying assets and any hedging before deciding how it fits your future spending.
Under current GOV.UK ISA guidance, someone who becomes non-UK resident can generally keep an existing ISA and retain UK tax relief on the holdings. They must notify the provider and normally cannot contribute while non-resident, with an exception for qualifying Crown employees overseas and their spouses or civil partners. An existing ISA can also be transferred to another provider.
The UK relief does not settle treatment under the Cyprus Income Tax Law. Have the actual account, income, residence and treaty position assessed separately.
Likewise, do not treat an accumulating fund as proof of no tax event or reporting obligation, or infer that every security disposal is outside Cyprus CGT. The CGT Law includes covered Cyprus-property interests and property-holding securities, with statutory conditions and exclusions. Check the actual instrument and applicable filing obligations with your adviser. Non-dom status is not a blanket exemption from every tax or contribution.
5. Learn the terms and keep records
Practise calculating interest, inflation effects, fees and the results of explicitly stated assumptions. Keep contracts, quotations and statements together. Discuss basic concepts with your children using examples suited to their age rather than promising an investment outcome.
For example, a hypothetical GBP 5,000 earning a constant 7% compounded annually for 47 years, without additions, tax, fees or withdrawals, becomes approximately GBP 120,229. The calculation is GBP 5,000 × 1.07^47. It does not predict market performance or purchasing power after inflation.
Set a review date and revisit the plan after a major change in work, family, residence or finances. Ask for an explanation when a product or fee is unclear before committing.
Frequently asked questions
Where do ordinary people lose money to the financial system?
Check the charges on your actual accounts and products: transaction fees, ongoing fund or adviser fees, currency conversion, borrowing and early-exit terms. The SEC explains that fees reduce the amount left earning returns. A universal fee percentage or promised annual saving does not describe every customer’s situation.
What percentage of active funds underperform the index?
Specify the fund category, benchmark and period. As a historical example, SPIVA’s U.S. Year-End 2024 report says 65% of active large-cap U.S. equity funds underperformed the S&P 500 in 2024. That is not a percentage for all active funds worldwide, nor a guarantee about a future fund.
How financially literate is the world?
The 2014 S&P Global FinLit Survey classified 33% of adults worldwide as financially literate under its test of understanding at least three of four concepts. It interviewed more than 150,000 adults in over 140 economies. This is historical survey evidence, not a measurement of the world in 2026.
How big is the global pension gap?
A 2017 World Economic Forum study projected a USD 400 trillion retirement-savings gap by 2050 across eight specified countries. Its calculation used assumptions including a target of 70% of pre-retirement income. It is a historical projection, not a current global deficit or a personal pension entitlement.
What should expats do to manage personal finances?
Review spending and fees, choose affordable saving arrangements, assess investments against risk and time horizon, check retirement scenarios, and reconcile tax and currency exposure across countries. Set assumptions for your own situation; no single savings percentage, fund or retirement age guarantees a suitable plan.
Where should I invest in index funds from Cyprus: Revolut or Interactive Brokers?
Compare the actual legal entity, eligible products, current fee schedule, custody terms, client-asset protection, transfers and tax records before choosing a broker. Do not infer legal ownership from the app’s design or assume recurring purchases are free. A particular broker or ETF is not suitable for every Cyprus resident.
