How the calculation works

  1. Assignment income is your rate multiplied by your hours or days.
  2. Our margin comes off: £20 a week on Standard, £22.50 on Platinum.
  3. Employer National Insurance at 15% above £96 a week is paid from what remains. What is left is your gross taxable pay.
  4. Your Income Tax, National Insurance and any student loan are deducted to give your take-home pay.

The calculator uses 2026/27 rates and thresholds and works on a single pay period. It assumes you have opted out of the workplace pension. If you stay in the pension, both you and Kingsley Crest contribute, which changes the figures; ask us for a personalised illustration.
