Why bonus money feels different

A bonus is one-off money, and the deduction pressure can feel sharper because users compare the gross figure emotionally, not just mathematically.

Step 2

Read the bonus impact clearly

This is designed to show what the bonus may feel like after deductions, not just what it says on paper.

Interpretation

This bonus should retain a relatively strong share after deductions

From a bonus of £5,000, the retained amount should still feel fairly visible. The gross number will not fully translate into take-home, but the deduction drag is not especially heavy here.
