The job offer says "£32,000 a year". That number is called your gross pay. Almost none of it lands in your bank account. The amount that actually does is called your net pay, or take-home pay. The gap between them is bigger than most people guess. We'll walk through it, deduction by deduction, until you know exactly where every pound goes.
The most common shock when people start working is the size of the gap between gross and net. A £30,000 salary doesn't put £30,000 in your bank account. It puts something closer to £24,000. Knowing exactly how this works is the first piece of financial literacy that every adult needs. And it's something the exam tests directly.
