How Much Should You Save?
Standard Recommendation:
Save 3-6 months of essential expenses. This covers rent/mortgage, utilities, food, transport, insurance, and minimum debt payments - not your entire income.
Adjust Based on Your Situation:
| Your Situation | Recommended Fund |
|---|---|
| Single income, stable job | 3-4 months |
| Dual income, stable jobs | 3 months |
| Self-employed | 6-12 months |
| Commission-based income | 6-9 months |
| Dependents or health issues | 6-12 months |
| Unstable industry | 9-12 months |
Calculate Your Target Amount:
Example Calculation:
- Rent/Mortgage: £1,200
- Utilities: £150
- Food: £300

Where to Keep Your Emergency Fund
Best Options for 2025:
1. Easy Access Savings Accounts (Best Choice)
Interest rates: 4-5% as of 2025
- Chase Saver: 4.75% on balances up to £250,000
- Marcus by Goldman Sachs: 4.65% easy access
- Chip Instant Access: 5.00% with app-based access
2. Cash ISAs (Tax-Free Option)
Interest rates: 4-4.5%, tax-free up to £20,000/year
- Plum Easy Access ISA: 4.51% tax-free
- Moneybox Cash ISA: 4.25% easy access
Avoid These for Emergency Funds:
- ✗ Stocks/shares (too volatile for emergencies)

- ✗ Notice accounts (30-90 day withdrawal delays)
- ✗ Premium Bonds (returns are unpredictable)
How to Build Your Emergency Fund
Step 1: Start with a Starter Fund
If 6 months feels overwhelming, start with £500-£1,000. This covers most minor emergencies like car repairs or boiler breakdowns.
Step 2: Automate Your Savings
Set up a standing order on payday to transfer money automatically:
- £50/week = £2,600/year
- £100/week = £5,200/year
- £200/month = £2,400/year
Step 3: Boost with Windfalls
Direct unexpected income straight to your emergency fund:
- Tax refunds
- Work bonuses
- Birthday money
- Cashback and rewards
- Side hustle income
Step 4: Cut Unnecessary Expenses
Find extra savings by reviewing:
- Unused subscriptions (streaming, gym, apps)
- Expensive mobile/broadband contracts
- Insurance policies (shop around annually)
- Eating out and takeaways
- Brand-name groceries vs supermarket own-brand
Emergency Fund vs Debt: What First?
Recommended Approach:
- Build £500-£1,000 starter emergency fund
- Pay off high-interest debt (credit cards, payday loans)
- Build full 3-6 month emergency fund
- Pay off remaining debt (personal loans, car finance)
When to Use Your Emergency Fund
True Emergencies:
- Job loss or reduced income
- Urgent medical expenses
- Essential home repairs (boiler, roof leak)
- Essential car repairs (if needed for work)
- Emergency travel (family illness)
Not Emergencies:
- Holidays or travel

- Home improvements or upgrades
- Sales or "too good to miss" deals

Frequently Asked Questions
How much should I have in my emergency fund?
Aim for 3-6 months of essential expenses. If you're self-employed, have dependents, or work in an unstable industry, target 6-12 months. Start with a £500-£1,000 starter fund if the full amount feels overwhelming.
Where is the best place to keep an emergency fund?
Keep it in an easy access savings account with competitive interest (4-5% as of 2025). Good options include Chase Saver, Marcus by Goldman Sachs, or a Cash ISA for tax-free interest. Avoid stocks, fixed-term bonds, or notice accounts.
Should I pay off debt or build an emergency fund first?
Build a small starter emergency fund (£500-£1,000) first, then focus on high-interest debt (over 10% APR). Once that's cleared, build your full 3-6 month emergency fund before tackling lower-interest debts.
What counts as a real emergency?
True emergencies include job loss, urgent medical expenses, essential home repairs (heating, plumbing), car repairs needed for work, or family crises. Holidays, new purchases, gifts, or planned expenses are NOT emergencies.
How long does it take to build an emergency fund?
It depends on your savings rate. Saving £200/month builds £1,000 in 5 months, or £6,000 in 30 months. Start with small milestones (£500, £1,000, 1 month's expenses) to stay motivated and build gradually.
