Take-home impact
The gross gap of £2,500/year translates into roughly £1,800/year after tax and NI — because marginal take-home on additional pay is 72% (20% tax + 8% NI) at this salary level. Roughly £150/month extra in the bank.
The pension alternative
If the higher rise is not on offer but extra pension contribution is, sacrificing the £2,500 gap into pension at 28% marginal relief turns it into the full £2,500 pension for a net cost of £1800. This is often the single most tax-efficient move available inside the current tax year.
What's realistic in the UK right now
UK private-sector median pay growth has run between 4% and 6% through 2024–25 (ONS AWE series). A 5% rise sits around the national median; 10% sits in territory usually reserved for promotions or counter-offers. If you're moving roles, the average switcher uplift is materially higher than the average stayer rise — worth comparing both.
Inflation-adjusted view
If CPI is running at 3%, the 5% rise is a real-terms 2.0% change and the 10% rise is a real-terms 7.0% change. Both rises beat inflation, but the gap of 5 percentage points compounds materially over time.
