Your First Job: A Money Guide for UK Graduates and School Leavers

SYM

Your first payslip is a life milestone — and probably a bit confusing. Why is the number smaller than your salary? What's National Insurance? Should you really care about a pension at 22? This guide covers everything they should have taught you at school about managing your first real income.

Understanding Your Payslip

That gap between your gross salary and what hits your bank account is explained by:
  • •Income Tax: 20% on earnings above £12,570 (your Personal Allowance). A £25,000 salary means tax on £12,430 = £2,486/year.
  • •National Insurance: 8% on earnings above £12,570. Same salary = £994/year.
  • •Pension: Usually 5% of qualifying earnings. Your employer adds at least 3%.
  • •Student Loan: 9% above the threshold (Plan 2: £27,295, Plan 5: £25,000). Only if you earn above the threshold.
  • •Net result: A £25,000 salary pays about £1,650-£1,750/month after all deductions.

The First Things to Set Up

Do these in your first month of employment:
  • •Check your tax code is correct (should be 1257L for most). Wrong codes mean you overpay.
  • •Don't opt out of your workplace pension — it's free money from your employer.
  • •Open a separate savings account (Chase, Monzo, or any high-interest option).
  • •Set up a standing order to save on payday — even £50/month starts the habit.
  • •Start a saving challenge on SYM — the 1p challenge is perfect for beginners.

How Much to Save From Your First Salary

The standard advice is 20% of take-home pay, but that's not realistic for everyone on a starter salary. Start with what you can — even 10% is excellent. The key is making it automatic from day one, before lifestyle inflation kicks in. If you get a pay rise later, save half the increase and spend half.

Avoiding First-Salary Traps

Common mistakes new earners make:
  • •Financing a car you can't afford — buy used, pay cash if possible
  • •Moving into the most expensive flat available — aim for rent under 30% of take-home
  • •Treating credit cards as 'extra money' — only use what you can pay off monthly
  • •Ignoring your pension because retirement feels distant (your future self will thank you)
  • •Keeping up with friends who earn more or have family support

Building Your First Emergency Fund

Before anything else, build a £1,000 mini emergency fund. This covers most unexpected expenses (phone repair, emergency travel, unexpected bill) without reaching for a credit card. Once you hit £1,000, work toward 3 months of expenses.

FAQ

Should I save or pay off student debt first?+

Save. UK student loans are deducted automatically and don't affect your credit score. Focus on building savings, an emergency fund, and good money habits. Read our <a href='/blog/student-loan-repayment-guide-uk'>student loan guide</a> for the full picture.

How much should I spend on rent?+

The rule of thumb is no more than 30% of your take-home pay. In expensive cities, 35% may be unavoidable. Above 40% makes it very hard to save or enjoy life.
