Decision insights
A meaningful share of the bonus is lost to deductions
Bonuses often feel smaller than expected because tax and National Insurance absorb a noticeable part of the gross amount.
Net bonus is the decision number that matters
A £5,000 bonus becomes roughly £2,938 after deductions, which is about £245 per month if you spread its value across a year.
Bonus efficiency matters more at this salary level
As salary rises, bonus money can feel less efficient than users expect, so it is worth comparing a bonus against permanent salary change or pension redirection.
Compare against salary growth
