The Direct Answer
On a £500/day rate (5 days/week, 48 weeks), working through an umbrella company, you can expect to take home approximately £290–£320/day — or around £68,000–£72,000/year — after all deductions. Use the calculator for your exact figures.
The Two Stages of Umbrella Pay Deductions
Umbrella pay is calculated in two distinct stages — understanding this is key to understanding why take-home pay is significantly lower than the day rate.
Stage 1: Deductions From the Assignment Rate
These are deducted before your gross salary is calculated:
- Employer's NI — 15% of assignment rate above £5,000
- Apprenticeship Levy — 0.5% of assignment rate
- Umbrella Margin — Fixed weekly/monthly fee
Stage 2: Deductions From Gross Salary (PAYE)
These are deducted from your gross salary — the same as any PAYE employment:
- Income Tax — 20% basic rate, 40% higher rate, 45% additional
- Employee NI — 8% between £12,570–£50,270, 2% above
- Pension — Employee contribution % (if applicable)
- Student Loan — If applicable — Plan 1, 2, 4 or Postgrad
Worked Example: £500/Day Rate
Let's walk through a complete calculation for a contractor earning £500/day, working 5 days/week for 48 weeks, with a £25/week umbrella margin and 3% employee pension:

Why Employer NI is So Important to Understand
The most common source of confusion for new umbrella contractors is the employer NI deduction. Here's why it matters so much:
On a £120,000 annual assignment rate, the employer NI alone is £17,250 — 14.4% of your entire assignment rate. Combined with the apprenticeship levy (£600), these two deductions alone account for nearly £17,850 before you even factor in income tax and employee NI.
This is the primary reason why contractors are often surprised when they see their payslip for the first time. The day rate they negotiated bears little resemblance to the gross salary on their payslip.

How Does This Compare to a Limited Company?
Contractors operating through their own limited company (outside IR35) typically take home significantly more — often £10,000–£20,000 more per year on the same day rate — because they can pay themselves a combination of salary and dividends, which are taxed at lower rates than PAYE income, and because employer NI on a low director's salary is minimal.
However, inside IR35, the tax treatment of a limited company becomes very similar to umbrella employment, and the administrative burden of a limited company may not be worth it.
