Salary and work
At work, percentages are talked about at the negotiating table, but your own finances run on pounds. A 3% rise means a different amount on a £2,200 and a £4,200 salary, and only part of a gross rise reaches your account. This topic's calculators turn percentages into pounds in both directions.

Background on this topic
Gross and net don't move at the same pace
From a £100 gross rise, a typical amount reaching your account is about £68–£72, once Income Tax, National Insurance and a workplace pension contribution have been deducted. A rise can also push your annual income into a higher tax band, so that part of it is taxed at a higher marginal rate.
What gets deducted from pay
A payslip typically has four items: Income Tax under your tax code, National Insurance, a workplace pension contribution and a voluntary trade union fee. The first three are statutory, and their percentages are confirmed for each tax year. Enter your own figures into the salary calculator.
Other topics
All the site's calculators are grouped into six topics. The same calculator can belong to more than one, because a percentage calculation is rarely tied to just one situation.
