For calculating gross pay from net pay you will need to make an initial guess for the gross figure and then start amending that figure in the appropriate direction until you arrive at the target net pay figure.
Although a directors' National Insurance contributions are generally calculated on a cumulative basis this calculator will always use a Month 1 basis. In practice this will mean that National Insurance contributions provided will vary from those on your payslip if you are a director.
This calculator is designed for the standard National Insurance category, ie. not contracted out of SERPS, and for persons aged between sixteen and retirement age (Category A).
This calculator is set up to calculate pay and tax details up to an annual salary of £100,000 (£8,333 per month). Gross pay entered in excess of this amount will understate PAYE due.
Please note, our calculator assumes you pay your contributions from NET PAY. The calculations will not be accurate if you pay your pension contributions as part of a salary sacrifice arrangement.
