Your first salary: what to do with it
The first few years of earning set habits that are hard to change later. This is the order that works.
Nobody teaches this, and the first few years of earning set habits that are hard to change later. Here is a sensible order of operations that does not require you to be interested in finance.
The order that works
- Do not opt out of the workplace pension. It is the only free money you will be offered.
- Build a starter buffer of around £1,000 in easy-access cash.
- Clear expensive debt — overdrafts and credit cards first.
- Grow the buffer to three months of essential spending.
- Then think about an ISA, a house deposit, or extra pension.
Why the pension matters more than it feels like it does
At 22, retirement is an abstraction and the pension deduction is a visible cut to a salary that already feels small. Opting out is understandable and it is almost always the most expensive decision of your early career.
Under auto-enrolment the total minimum contribution is 8% of qualifying earnings, of which at least 3% comes from your employer. Opting out does not just cost you your own 5% — you also throw away the employer's 3% and the tax relief. That is a guaranteed, instant return that no investment can match. Many employers will also match above the minimum, which is the closest thing to free money most people are ever offered.
Time is the other half. Money contributed in your twenties has forty years to compound; the same money at forty has half that. The early contributions do a disproportionate amount of the work.

Put a modest monthly figure and forty years into the pension calculator. The number is usually the most persuasive argument there is.

Your gross salary is not your money. Income tax, National Insurance, pension and possibly a student loan repayment come out before anything reaches your account. Budgeting against the headline number is how people end up short every month.
Work out your actual monthly take-home first, then build everything on that figure.
Lifestyle creep is the real risk
Pay rises tend to be absorbed within a month or two — a slightly nicer flat, more takeaways, a car on finance — and then the raise is gone and nothing has improved. The single most effective habit in early-career finance is to bank a portion of every pay rise before you adjust to it. Increasing your pension contribution by 1% each time you get a raise is nearly painless and enormously effective.
Car finance deserves a specific warning. It feels like a manageable monthly cost, but it is a committed outgoing that reduces mortgage borrowing capacity by a surprising amount when you later come to buy a home.
ISA or pension in your twenties?
Both, in a specific order. Take the full employer pension match first — nothing beats it. After that, an ISA is often the better home for the next chunk, because the money remains accessible for a house deposit, whereas pension money is locked until at least 57.
If you are a first-time buyer under 40, the Lifetime ISA adds a 25% government bonus on up to £4,000 a year, though its exit rules are strict enough to read carefully first.
Platform and fund fees come out of your return every year, and the difference between providers compounds over decades. Compare UK broker and ISA platforms → Capital at risk. Advertising — we may earn a commission.
What not to worry about yet
Individual share picking, crypto, day trading, and elaborate spreadsheets. In your first years of earning, the outcome is determined almost entirely by three things: not opting out of the pension, avoiding expensive debt, and saving a consistent percentage of a rising income. Everything else is detail.
Common questions
Should I opt out of my workplace pension when I start work?
Almost never. Opting out forfeits your employer's contribution and tax relief as well as your own savings, and contributions made in your twenties have the longest time to compound. If money is tight, contributing at the minimum is better than opting out entirely.
How much of my first salary should I save?
A common target is 20% of take-home pay across pension, savings and debt repayment combined, but the more useful rule is to start with whatever is sustainable and increase it with every pay rise before you adjust to the money.
ISA or pension in my twenties?
Take the full employer pension match first, since that is a guaranteed return. After that an ISA often makes sense for money you may need before retirement, such as a house deposit, because pension money is locked away until at least age 57.
Is car finance a bad idea for a first job?
It is not automatically wrong, but it is a committed monthly outgoing that lenders deduct when assessing mortgage affordability, so it can substantially reduce how much you can borrow when you come to buy a home.
