Umbrella assignment-rate calculator
See how an umbrella assignment rate could become gross salary and take-home pay after employer costs.
Before you start: This assumes steady work at 2026/27 England rates, with employer NI at 15% above £5,000 and no Employment Allowance. Employer pension uses qualifying earnings; if it is above zero, employee pension is set to 5% of qualifying earnings. Enter the levy rate that applies. Holiday pay is included in gross pay and paid out. Other NI categories, loans, expenses and salary sacrifice are not included.
