Required Salary Calculator
Most salary calculators go one way. This one goes backwards: tell it what you need to take home and it finds the gross salary that gets you there.

Why the gap is bigger than you expect
To take home an extra £100 a month you need considerably more than £100 a month of extra salary — how much more depends entirely on which tax band the increase falls into. A basic-rate taxpayer needs about £139 of gross pay to net £100. A higher-rate taxpayer needs £172. Someone caught in the £100,000–£125,140 personal allowance taper needs £263.
Using this for a pay rise conversation
If you need a specific figure in your account — to cover a mortgage, say — asking for that number as a pay rise will leave you short. Work out the gross figure first, and negotiate on that. It also helps to know your marginal rate: if you are just below a threshold, a modest rise keeps more of itself than a large one that pushes you over.
Salary sacrifice can beat a pay rise
If the goal is to fund a pension, a car or childcare rather than to spend the money, salary sacrifice delivers more per pound than a rise. It comes off before tax and National Insurance, so £100 of sacrifice costs a basic-rate taxpayer £72 of take-home pay rather than the £139 of gross salary a rise would need.

The figure shown assumes Income Tax and National Insurance only. If you have a student loan or pension contributions, you will need a higher gross salary — model the exact combination in the main calculator.
