Entry-Level Career Progression

This comparison is typical for early career moves or first promotions. At this salary range, most of your income is taxed at the basic rate (20%), so you keep a higher percentage of any raise.

  • Negotiate hard - you keep ~70-80% of any increase at this level
  • Consider employers offering good pension matching (often worth more than small salary differences)
  • Look for roles with clear progression paths to higher bands
  • Factor in benefits like free lunches, gym memberships, or transport subsidies
