How umbrella company pay is calculated in the UK
When you work through a UK umbrella company, you become an employee of the umbrella provider. Your recruitment agency or client pays the umbrella company an agreed assignment rate, which represents the total contract revenue rather than your personal salary.
From this gross revenue, the umbrella company first deducts its weekly or monthly administration margin (typically £20 to £30 per week). It then deducts statutory employer employment costs, which include Employer Class 1 National Insurance and the 0.5% Apprenticeship Levy.
The remaining balance forms your gross taxable employment salary. The umbrella company then applies standard PAYE deductions: employee Income Tax, employee Class 1 National Insurance, and any applicable student loan repayments or workplace pension contributions, transferring the net figure to your bank account.
Worked example: £500 daily rate umbrella take-home
Consider a contractor on a £500 per day assignment rate billing 230 working days per year (gross revenue of £115,000.00), with a £25 weekly umbrella fee and no student loan in England.
After accounting for the umbrella margin and employer costs (Employer National Insurance and the Apprenticeship Levy), standard PAYE Income Tax and employee National Insurance are deducted from gross earnings.
Total statutory and umbrella deductions equal £46,969.87, leaving a net annual umbrella take-home pay of £68,030.13 (equivalent to £5,669.18 per month), representing an overall retention rate of 59.16%.
For comparison, working outside IR35 through a personal service company (PSC) on the same contract revenue yields an estimated take-home pay of £73,669.73, giving a limited company advantage of £5,639.60 per year.
Why employer National Insurance appears on an umbrella payslip
Contractors new to umbrella companies are often surprised to see Employer National Insurance listed on their payslip. Under UK employment law, the employer must pay secondary Class 1 National Insurance on earnings above the secondary threshold.
Because the agency assignment rate is specifically negotiated to cover both employer statutory costs and employee pay, the umbrella company deducts these mandatory employer liabilities from the contract invoice value before arriving at your gross salary.

CALCULATOR QUESTIONS
Umbrella company calculator questions
What is the difference between an umbrella company and PAYE agency payroll?
With direct agency PAYE, the recruitment agency employs you directly and pays you a PAYE rate. With an umbrella company, you are employed by the umbrella across multiple assignments, maintaining continuous employment rights and statutory benefits.
Why is my umbrella take-home pay lower than an outside IR35 contract?
Umbrella payments are treated entirely as employment income subject to Employer NI, Employee NI, the Apprenticeship Levy, and Income Tax. Outside IR35 contractors operate through a limited company and can distribute profits via tax-efficient dividends after Corporation Tax.
Can I claim travel and subsistence expenses through an umbrella company?
Under UK Supervision, Direction, or Control (SDC) legislation, most umbrella workers cannot claim tax relief on home-to-work travel and subsistence expenses unless they can prove they are not subject to SDC on the assignment.
How does holiday pay work with an umbrella company?
Umbrella companies legally reallocate 12.07% of your gross pay into a holiday pay fund. You can choose to have this holiday pay rolled up and paid out weekly with your wages or accrued and paid when you take time off.
