Pay Rise Calculator – FAQs
How does this pay rise calculator work?
This calculator compares your current pay with your pay after a rise. It estimates Income Tax, National Insurance, pension contributions and student loan repayments for both scenarios, then shows the difference in annual, monthly and weekly take-home pay.
Can I enter a new salary instead of a percentage rise?
Yes. You can use this calculator in three ways: enter your new salary directly, enter a known £ increase, or enter a percentage pay rise. The calculator then works out your updated gross and net pay automatically.
Does a pay rise always increase take-home pay by the same percentage?
No. A pay rise increases your gross salary, but part of the increase may be lost to Income Tax, National Insurance, student loan deductions and pension contributions. Your take-home increase is usually lower than the headline rise.
Can I include pension and student loan deductions?
Yes. You can enter pension details, student loan settings and tax code information so the estimate better reflects your real take-home pay after a pay rise.
Can I adjust bonus, overtime and benefits after the rise?
Yes. If your pay rise also affects bonus, overtime, salary sacrifice or taxable benefits, you can enter separate before and after values to compare the full package.
Is a £2,000 pay rise worth the same at every salary?
Not always. The value of a pay rise after tax depends on your overall income and deductions. The same gross increase can produce different net gains depending on your tax band, pension setup and student loan position.
Is this calculator accurate?
This tool provides an estimate based on UK tax rules for the 2026/27 tax year. Actual payslip results may vary depending on your payroll setup and personal circumstances, but it gives a strong indication of your likely net gain.
