Case Study: How Sarah Consolidated Her US, UK, and Singapore Finances
This case study shows exactly how to consolidate finances across multiple countries after years of international moves. Sarah’s experience—organizing 14 scattered accounts across three countries into a unified system—offers a practical roadmap for anyone facing similar challenges.
Key Insight: Sarah discovered she had $67,000 less than she thought due to untracked fees, forgotten account closures, and currency fluctuations. After consolidation, she reduced financial admin from 25+ hours annually to just 3 hours, while gaining complete visibility over her wealth.
Meet Sarah: A Decade of International Moves

- 2014-2018: New York (4 years)
- 2018-2021: London (3 years)
- 2021-2024: Singapore (3 years)
- 2024-present: Back to London
Each move was exciting. Each move also left behind a trail of financial accounts, retirement plans, and loose ends.
When Sarah and I spoke in late 2025, she was preparing for something that terrified her: trying to figure out her actual net worth.
“I know I should be in decent shape financially,” she told me. “But I genuinely couldn’t tell you within $50,000 what I’m worth. That’s insane for someone who’s worked in consulting.”
This is her story of getting organized – the process, the discoveries, and the system that finally gave her clarity.
The Discovery Phase: What Sarah Actually Had
Sarah started by creating an inventory of every financial account she could remember. The list was longer than she expected.
United States (2014-2018)
| Account Type | Institution | Estimated Balance | Status |
|---|---|---|---|
| 401(k) #1 | Fidelity | ~$45,000 | Active, no contributions |
| 401(k) #2 | Vanguard | ~$28,000 | Active, no contributions |
| Roth IRA | TD Ameritrade | ~$22,000 | Active, no contributions |
| Checking | Chase | $2,400 | Active, minimal use |
| Savings | Ally | $15,000 | Active |
| HSA | Optum | ~$8,500 | Active, forgotten |
| Stock options | Former employer | Unknown | Need to investigate |
Total estimated US assets: ~$121,000 (but she wasn’t sure about the stock options)
United Kingdom (2018-2021)
| Account Type | Institution | Estimated Balance | Status |
|---|---|---|---|
| Workplace pension | Scottish Widows | ~£35,000 | Active, no contributions |
| ISA | Hargreaves Lansdown | ~£18,000 | Active, dormant |
| Current account | HSBC UK | £850 | Active, rarely used |
| Savings | Marcus | £5,000 | Active, rarely used |
Total estimated UK assets: ~£59,000 (~$75,000)
Singapore (2021-2024)
| Account Type | Institution | Estimated Balance | Status |
|---|---|---|---|
| CPF (mandatory savings) | Government | ~SGD 95,000 | Active, restricted access |
| Savings | DBS | SGD 45,000 | Active, main savings |
| Investment account | StashAway | SGD 65,000 | Active |
| Crypto (bought in SG) | Crypto.com | ~SGD 8,000 | Active |
Total estimated Singapore assets: ~SGD 213,000 (~$160,000)
Other
- Real estate: None (always rented)
- Debts: None (paid off student loans in 2020)
- Insurance with cash value: None
Sarah’s rough estimate of her total net worth: ~$360,000
But she knew this number was unreliable.
The Problems Sarah Discovered
Once Sarah started actually logging into accounts and verifying balances, she found several issues:
Problem 1: The Forgotten HSA with $3,500 in Hidden Fees
Sarah’s HSA from her US employer had been charging $3.50/month in administration fees since 2018. That’s $252 in fees – not huge, but annoying. Worse, the HSA was still invested in the default money market fund earning basically nothing, while it could have been invested in index funds.
Actual HSA balance: $5,100 (not $8,500)
Problem 2: The Stock Options That Had Expired
Remember those stock options from her first employer? Sarah finally tracked them down. They had a 7-year exercise window. It was now year 11.
Value of expired options: $0 (potentially worth ~$40,000 if exercised in time)
This was the most painful discovery. She’d always assumed she could deal with them “later.”
Problem 3: Currency Swings She Hadn’t Noticed
Sarah had been mentally tracking her UK assets at the exchange rate from when she left (1.35 USD/GBP). The actual rate when she did her audit was 1.27.
Impact: ~$4,700 less than she thought in her UK accounts
Problem 4: The Duplicate 401(k)s
Sarah had two separate 401(k)s from two different employers, both at different providers. Neither had been touched in years. One was in a target-date fund with high fees (0.75%/year), costing her roughly $210 annually more than necessary.
Problem 5: Singapore CPF Access Restrictions
Sarah had assumed her CPF money (~SGD 95,000) was fully accessible. It’s not. Singapore’s CPF has complex withdrawal rules – much of it is locked until age 55, and as a non-citizen who has left, her options are limited.
Truly accessible Singapore assets: ~SGD 118,000 (not 213,000)
Revised Net Worth After Audit
After going through everything properly:
| Region | Originally Estimated | Actual Value | Difference |
|---|---|---|---|
| US | $121,000 | $81,000 | -$40,000 |
| UK | $75,000 | $70,300 | -$4,700 |
| Singapore | $160,000 | $137,500 | -$22,500 |
| Total | $356,000 | $288,800 | -$67,200 |
Sarah’s actual net worth was $67,200 lower than she thought. Most of that was the expired stock options – an expensive lesson in procrastination.
The Consolidation Strategy
Once Sarah had the real numbers, she developed a plan:
Phase 1: Close and Consolidate (Month 1-2)
US Actions:
- Roll both 401(k)s into a single rollover IRA at Schwab
- Transfer the HSA to Fidelity (no fees, better investment options)
- Keep the Roth IRA at TD Ameritrade (no reason to move)
- Close the Ally savings account (didn’t need two US savings accounts)
- Keep Chase checking (useful for occasional US expenses)
UK Actions:
- Keep the workplace pension (can’t easily move, low fees anyway)
- Keep the ISA (tax advantages worth maintaining)
- Close the Marcus savings (moved funds to ISA)
- Keep HSBC current account (minimum needed for UK presence)
Singapore Actions:
- Accept that CPF is inaccessible until 55
- Keep DBS account (may return to Asia)
- Keep StashAway (good platform, reasonable fees)
- Move crypto to a hardware wallet
Phase 2: Set Up Unified Tracking (Month 2)
Sarah signed up for PopaDex to track everything in one place.
Accounts connected automatically:
- Chase (US)
- Schwab rollover IRA (US)
- TD Ameritrade Roth IRA (US)
- Fidelity HSA (US)
- HSBC UK
- Hargreaves Lansdown ISA
- DBS Singapore
- StashAway
Accounts added manually:
- Scottish Widows pension (updated quarterly from statements)
- CPF (updated annually, marked as “restricted”)
- Crypto (updated monthly from wallet)
Total accounts tracked: 12 (down from 14 before consolidation)
Phase 3: Ongoing Maintenance (Monthly)
Sarah now spends about 15 minutes per month:
- Checking PopaDex dashboard for any anomalies
- Verifying the total makes sense given income/expenses
- Updating manual accounts if needed
Once per year (she chose her birthday), she does a deeper review:
- Updating all manual balances
- Reviewing fees on all accounts
- Reassessing currency allocation
- Checking beneficiary designations
The Results After One Year
Twelve months after her initial audit, Sarah’s financial situation looked very different:
Net Worth Growth
| Month | Net Worth | Change |
|---|---|---|
| Start | $288,800 | - |
| Month 6 | $318,200 | +$29,400 |
| Month 12 | $347,500 | +$58,700 |
Not all of that was savings – investment growth and currency movements helped. But Sarah was now saving more consistently because she had clear visibility.
Fees Saved
- Moved 401(k) from high-fee fund: ~$350/year
- Moved HSA to no-fee provider: ~$42/year
- Closed unnecessary accounts: ~$75/year in miscellaneous fees
Annual fee savings: ~$467
Time Saved
- Before: 6-8 hours quarterly trying to piece together net worth
- After: 15 minutes monthly plus 2 hours annually
Annual time savings: ~22 hours
Peace of Mind: Priceless
“I actually understand my finances now,” Sarah told me. “Before, money was this stressful black box. Now it’s just… numbers I can see and manage. The anxiety is gone.”
Lessons for Other Multi-Country Expats
Sarah’s experience highlights several universal lessons:
1. Do the Inventory Now
The longer you wait, the more likely something expires, gets lost, or erodes with fees. Sarah lost $40,000 in stock options because she assumed she had time.
Action: Block 3 hours this weekend to list every financial account you can remember.
2. Currency Matters More Than You Think
Sarah was mentally tracking in different currencies and adding them up without proper conversion. This gave her false confidence.
Action: Pick a base currency and convert everything consistently.
3. “Accessible” vs “Technically Yours” Is an Important Distinction
Sarah’s Singapore CPF is real money, but it’s not accessible for decades. Understanding liquidity constraints prevents planning errors.
Action: Categorize every asset by when you can actually access it.
4. Consolidation Has Real Benefits
Fewer accounts means:
- Less to track
- Fewer fees
- Simpler tax reporting
- Less chance of something being forgotten
Action: Ask “Do I really need this account?” for everything you have.
5. Automation Removes Excuses
When Sarah had to manually check 14 accounts and do currency conversions in a spreadsheet, she avoided it. With automated tracking, she actually looks at her finances regularly.
Action: Use a tool that automates as much as possible.
Sarah’s Current Setup
Here’s how Sarah’s financial tracking works today:
Primary tracking tool: PopaDex
- 9 connected accounts (auto-sync daily)
- 3 manual accounts (updated monthly/quarterly)
- Base currency: GBP (where she now lives)
Supplementary tracking:
- Our Google Sheets tracker for detailed categorization and planning scenarios
Key metrics she monitors:
- Total net worth (GBP and USD)
- Currency allocation (% in each currency)
- Liquidity breakdown (% accessible in <1 week vs locked)
- Monthly savings rate
Annual review checklist:
- Verify all balances
- Review investment allocation
- Check fees on all accounts
- Update beneficiaries
- Review tax implications
The Bottom Line
Sarah went from:
- 14 accounts she couldn’t keep track of
- ~$67,000 less than she thought she had
- 25+ hours annually spent on financial admin
- Constant low-grade anxiety about money
To:
- 12 accounts with unified tracking
- Clear knowledge of exactly what she has
- ~3 hours annually on financial admin
- Confidence and clarity
The transformation didn’t require sophisticated financial engineering. It required:
- Taking inventory
- Consolidating where possible
- Setting up automated tracking
- Building simple habits
“If I could go back and tell my 2018 self one thing,” Sarah said, “it would be: ‘Deal with your old accounts before your next move. Future you will thank you.’“
Frequently Asked Questions
How do I consolidate finances across multiple countries?
Start by creating a complete inventory of all accounts across every country you’ve lived in. Then consolidate redundant accounts (close dormant checking accounts, roll over small retirement accounts where tax-efficient). Set up unified tracking using a tool like PopaDex, and establish a regular review schedule.
Should I close foreign bank accounts after moving?
Not necessarily. Keep accounts with tax-advantaged retirement assets, in countries you may return to, or where you need local currency liquidity. Close accounts with high maintenance fees, low balances that don’t justify the complexity, or where you have no ongoing need. Always check tax implications first.
How long does it take to organize multi-country finances?
The initial inventory and setup typically takes 4-8 hours spread over 2-4 weeks. Consolidating redundant accounts may take additional weeks depending on institutions’ processes. Once set up, ongoing maintenance requires only 3-5 hours annually with proper automation.
What tools work best for tracking assets across multiple countries?
Purpose-built international tools like PopaDex connect to 15,000+ banks across 30+ countries. Spreadsheets work for simple situations but become unmanageable beyond 5-10 accounts. Single-country apps like Mint or Personal Capital don’t handle multiple currencies or foreign institutions.
