How Much Should I Save Each Month? (UK Benchmarks by Age & Income)

There's no single right answer — but there IS a process. Use these UK benchmarks, the 50/30/20 rule, and a worked example to find a savings rate you can actually stick to.

The starting point: 50/30/20

If you want one number to aim for, it's 20% of net income saved or invested. The 50/30/20 rule (popularised by Senator Elizabeth Warren) splits after-tax income like this:

• 50% needs — rent or mortgage, bills, food, transport, minimum debt payments, insurance
• 30% wants — eating out, hobbies, holidays, subscriptions, non-essential shopping
• 20% savings — pensions, ISAs, investments, and debt repayment above minimums

On a £30,000 salary in the UK (after basic-rate tax and NI, roughly £24,000 net), 20% is about £400 a month. That's a realistic starting point — not a stretch goal.

Savings targets by age (UK rule of thumb)

The classic US benchmark is to have savings equal to 1× salary by age 30, doubling each decade. That maps onto UK salaries roughly like this, assuming you're saving for a moderate retirement (~£31k/year per the PLSA):

• Age 25: ~£15,000 (about half your annual salary if you earn £30k; the bookkeeping is forgiving early)
• Age 30: ~£30,000 (1× salary)
• Age 40: ~£90,000 (3× salary)
• Age 50: ~£180,000 (6× salary)
• Age 60: ~£270,000 (9× salary, often with the State Pension still to come at 67)

These are total figures including pension pots, ISAs, and other investments — not just cash savings. Use the retirement calculator to check whether you're on track for your specific retirement goal.

When 20% isn't possible — and when it's too low

20% is a starting point, not a target. Real life is messier:

• If you have expensive debt (credit cards, overdrafts, buy-now-pay-later at 20%+): pay that down aggressively first. Saving 20% into a 4% account while paying 22% APR on debt is maths working against you.
• If you're saving for a house deposit: you may temporarily need to save 30–40%+ (especially in London/South East). Automation helps. See the savings goal calculator to work out the monthly amount.
• If your income is below ~£20k: 20% may simply not be achievable on essentials. Aim for what's possible — £50/month beats £0/month, and habit-building is the long game.
• If you earn £80k+: 20% might not even be the right minimum. Higher earners often aim for 30–40% to hit retirement targets faster.

Where that 20% should go — the order

The right order to use your 20% matters more than the exact figure. A common UK order:

1. Employer pension match — at minimum, contribute enough to get the full employer match. Free money.
2. High-interest debt — clear credit cards, overdrafts, BNPL above 10% APR. See the credit card payoff calculator.
3. Emergency fund — 3–6 months of essential expenses in an easy-access savings account.
4. SIPP or ISA — if you've used your workplace pension and want more tax-efficient investing. Stocks & Shares ISA for flexibility, SIPP for tax relief + later access.
5. Specific goals — house deposit, car, big holiday in a separate easy-access account.

Worked example: £30k salary, single, renting in Manchester

Net income after tax and NI: ~£2,000/month. Split with 50/30/20:

• Needs (£1,000/mo): £700 rent, £150 food, £80 transport, £70 bills
• Wants (£600/mo): eating out, hobbies, phone, subscriptions
• Savings (£400/mo): £150 into workplace pension (matched), £100 emergency fund top-up, £150 into a Stocks & Shares ISA

That £400/month, invested at 7% over 35 years, becomes roughly £680,000 — enough for a moderate retirement plus State Pension. Model this on the compound interest calculator →

How to actually stick to it

• Automate the day after payday — set up a standing order to a separate savings/investment account. Money you don't see, you don't spend.
• Increase when income increases — when you get a pay rise, send at least half of it to savings before you get used to spending it.
• Review quarterly — life changes, savings rates should too. Adjust based on what actually happened last quarter, not what you planned six months ago.

Frequently asked questions

How much of my monthly income should I save?

A common starting point is 20% of net income, known as the 50/30/20 rule. But the right number depends on your goals, debts and life stage. If you have high-interest debt, prioritise paying that off first. If you're saving for a house deposit, you may need to save more temporarily.

How much should I have saved by age 30 UK?

A common rule of thumb is to have 1× your annual salary saved by age 30. If you earn £30,000, aim for about £30,000 in savings and investments. This includes pensions, ISAs and other savings — not property value.

What is the 50/30/20 rule?

Allocate 50% of after-tax income to needs (rent, bills, food, transport), 30% to wants (eating out, hobbies, holidays), and 20% to savings and debt repayment above minimums. It's a starting point, not a strict rule — adjust based on your goals and circumstances.

Bottom line

20% is the headline, but the habit of saving something every month beats any single target number. Use the savings goal calculator to find a monthly amount that matches a specific goal (house deposit, retirement pot, emergency fund), start automating it, and the compounding does the heavy lifting over time. The compound interest calculator shows what that monthly amount becomes over 10, 20 and 30 years.
