Scenario

A GBP 2,000 bonus is small enough to feel like a reward rather than a compensation restructure, but it is still large enough for the after-tax gap to be noticeable. This is the kind of bonus people often spend in their heads before the payslip arrives.

What the output usually shows

The gross bonus does not flow straight into cash. Income tax takes a slice, employee NI takes another, and student loan deductions may reduce it further if the borrower is above the relevant threshold. That is why even a modest bonus can feel meaningfully lighter than the headline number.

Practical interpretation

At this size, the lesson is often behavioural rather than strategic: a bonus is marginal income, not clean free cash. If you are weighing whether variable pay matters in a package, even a small example like this helps reset expectations.
