What this gap actually feels like
A £75,000 annual salary works out to about £38.46 per hour, £288.46 per day, or £6,250 per month (based on a 37.5-hour week, before tax).
A £100,000 annual salary works out to about £51.28 per hour, £384.62 per day, or £8,333 per month (based on a 37.5-hour week, before tax).
The headline uplift from £75,000 to £100,000 is £25,000 per year — but the net uplift depends on which tax bands each salary crosses. £75,000 sits in the higher-rate (40%) band while £100,000 reaches into the 60% taper zone band — meaning the marginal income is taxed at a higher rate than the base salary.

Context: where do these sit nationally?
The UK median full-time salary is around £35,000 (ONS, 2024). £75,000 sits 114% above the median; £100,000 sits 186% above the median. In London, the median is roughly £44,000 — both of these numbers shift their perceived value depending on local housing costs, which can easily swallow the entire gross uplift.
Pension & sacrifice considerations
Because the marginal tax rates differ materially between these two salaries, pension sacrifice has meaningfully different value. At £100,000, each £1,000 sacrificed into pension saves 42% (40% tax + 2% NI) at the margin — making the pension the most tax-efficient home for a bonus or pay rise in this band.
