How much should I save?
A realistic savings target for your income and goals.
“How much should I save?” has no single answer — but it has a sensible structure. If you build your savings in the right order, the target for your situation becomes clear. Here’s the framework.
Step 1: Emergency fund first
Before anything else, build a 3–6 month buffer of essential costs. Three months if your income is stable, six if it’s not. This isn’t for holidays — it’s what keeps you out of credit card debt when life happens. Keep it in an easy-access savings account. See our building an emergency fund guide.
Step 2: The 10–20% benchmark
Once the emergency fund exists, a realistic long-term target is 10–20% of after-tax income. That covers retirement savings, big goals and lifestyle. If you’re just starting, even 5% builds the habit — raise it at every pay rise.
Example — £2,400 a month after tax. Saving 15% = £360 a month. At 5% interest, that’s roughly £28,000 in five years (try the savings calculator for your exact figure).
Step 3: Fill your ISA first
Shelter savings from tax using your £20,000 ISA allowance (2026/27). Interest inside an ISA is tax-free, and cash ISAs can be withdrawn at short notice — a natural home for both your emergency fund and goal savings. For retirement, use your workplace pension first to grab the employer match and tax relief.
Step 4: Match savings to timeframes
Different goals need different homes:
- 0–2 years (emergency fund, short goals) — easy-access savings, cash ISA
- 2–5 years — notice accounts, fixed-term savings, cash ISA
- 5+ years (retirement, long-term) — pension and stocks & shares ISA, where growth has time to work
Step 5: Automate it
Decide the monthly amount, set an automatic transfer on payday, and forget about it. Automated saving is the closest thing to effortless money management — the habit beats the amount.
Watch the tax
Outside an ISA, most people have a Personal Savings Allowance — £1,000 of savings interest a year for basic-rate taxpayers, £500 for higher-rate, £0 for additional-rate. Keep savings inside ISAs to stay simple and tax-free.

Frequently asked questions
How much should I save each month?
A common benchmark is 10–20% of after-tax income, but the right figure depends on your goals. Start with what's realistic and increase it over time — consistency beats size.
What is the emergency fund rule?
Save 3–6 months of essential expenses (rent, bills, food, minimum debt payments) in an easily accessible savings account before investing for the long term.
What is the 50/30/20 rule for saving?
It suggests 20% of after-tax income goes to savings and debt repayment, 50% to needs and 30% to wants. It's a guideline — adapt it to your life.
How much can I save in an ISA?
£20,000 per tax year across your cash and stocks & shares ISAs (2026/27). Within that, a Lifetime ISA caps at £4,000 a year, and a Junior ISA at £9,000.
Should I pay off debt or save first?
In most cases, clear high-interest debt first (credit cards and payday loans), then build your emergency fund, then save and invest. Mortgages and student loans are usually lower priority.
