Pick the tax year for which you want to work out your after-tax salary. This calculator has the capability to display your pay details, as they would have been, back as far as 1999.

Remember that the tax year begins on 6 April of each year

This is NOT required. However, if you know your tax code, include it here, and the answer will be more accurate, as all assumptions the calculator makes will be disregarded.

If you pay into a pension via the PAYE system on a monthly basis, enter the amount here.

This can be in percentage format eg. 4% of your salary, or you can enter the actual amount you pay into a pension per MONTH eg. £500.

If you went to university, started in 1998 or later, and took out a Student Loan Company loan, then this is repaid through the PAYE system.

You begin to repay the loan once your earnings go above a certain threshold, currently £15,000. Student loans will be repaid at a rate of 9% of the additional income over and above this threshold. Tick the box to include the repayment in your calculations.

If you took out a student loan before 1998, you have to repay this by Direct Debit, not through the PAYE system. This means it can’t be included in this calculator.

Tax Free Allowances: If you receive any additional tax-free annual allowance, include them here.
Deductions from Tax Free Allowance: Equally, if your tax-free allowance needs to be reduced, include any deductions from it here.

If you have both allowances and deductions, enter the net figure. Eg. If you have a £200 allowance but a £300 deduction, enter a tax free deduction of £100.
