About the salary increase calculator
How does a percentage pay rise work?
A percentage rise is applied to your current gross annual salary — your pay before any deductions. A £40,000 salary with a 5% pay rise becomes £42,000.
Why doesn't my take-home pay rise by the same percentage?
A higher gross salary can also mean more Income Tax, National Insurance, pension deductions and, where applicable, student loan repayments. So a 5% increase in gross salary does not normally mean a 5% increase in take-home pay.
For Civil Service Alpha members, a pay rise can also affect pension contributions and the pension you build. Moving into a different employee contribution band can change how much is deducted from pay.
What about a pay cut or part-time work?
The calculator works the same way for a lower salary. You can enter a lower annual salary, a negative percentage change, a negative £ amount change, or work out a salary from part-time hours as a share of the full-time equivalent.
