Umbrella take-home pay confuses most contractors at first. The day rate your agency quotes is not what you receive. Costs come out before your gross pay is set. Then tax and NIC come off the gross. This guide shows you how it works, step by step.
DASA Umbrella holds dual accreditation from FCSA and Professional Passport. DASA is a umbrella payroll company with that same dual accreditation. If you want the wider tax picture, read our umbrella contractor pay and tax guide.
How does umbrella pay get calculated?
Umbrella take-home pay starts with your assignment rate. The umbrella deducts employer NIC (15%), the apprenticeship levy (0.5%), its margin, and holiday pay. What is left is your gross pay. Income tax and employee NIC then come off your gross. The final amount is your net take-home pay.
There are two stages to the calculation. Stage one turns the assignment rate into gross pay. Stage two turns gross pay into take-home pay through PAYE.
Most contractors only think about stage two. Stage one is where the real impact sits. Employer NIC alone takes 15% of your earnings above £5,000. That is a big cut before tax even starts.
What is an assignment rate?
The assignment rate is the total amount your agency or client pays your umbrella for your work. It is sometimes called the contract rate or the umbrella rate. It is not your gross salary. It is the pot the umbrella works from. Your gross salary is what is left after employer costs come out.
If your agency quotes £350 per day, that is your assignment rate. Your umbrella takes employer NIC, levies, its margin, and holiday pay from that figure. Whatever remains is your gross pay.
This is why two contractors on the same day rate can have different take-home amounts. Different pension contributions, different holiday pay methods, and different margins all change the result.
What gets deducted before you are paid?
Stage one deductions come out of the assignment rate. These are employer-side costs:
- Employer NIC: 15% of earnings above £5,000 per year
- Apprenticeship levy: 0.5% of earnings above £15,000 per year
- Umbrella margin: Fixed weekly or monthly fee
- Holiday pay: Either rolled up at 12.07% or accrued until taken
Stage two deductions come off your gross pay through PAYE:
- Income tax: 20% basic rate, 40% higher rate, 45% additional rate
- Employee NIC: 8% up to £50,270, then 2% above
- Employee pension contribution: Usually 5% minimum under auto-enrolment

A worked example at 2026-27 rates (£350/day)
Here is a step-by-step calculation for a contractor on £350 per day, working 5 days a week. Assumptions: 46 working weeks per year, rolled-up holiday pay, standard tax code 1257L, 5% employee pension contribution, no salary sacrifice.
Annual assignment rate: £350 x 5 days x 46 weeks = £80,500
Stage one: employer-side deductions
Holiday pay (rolled up at 12.07%): £80,500 / 1.1207 = £71,830 base + £8,670 holiday pay. Working with the base of £71,830 for employer cost calculations:
Employer NIC secondary threshold: £5,000 per year. Employer NIC at 15% on (£71,830 – £5,000): £10,025. Apprenticeship levy at 0.5% on (£71,830 – £15,000): £284. Umbrella margin (example): £125 per month x 12 = £1,500.
Total employer deductions: £10,025 + £284 + £1,500 = £11,809
Gross pay: £71,830 – £11,809 = £59,421 before PAYE. Gross pay including holiday pay: £59,421 + £8,670 = £68,091 annual gross.
Stage two: PAYE on gross pay of £68,091
Personal allowance: £12,570, no tax. Basic rate 20% on £37,700 (£12,571 to £50,270): £7,540. Higher rate 40% on £17,821 (£50,271 to £68,091): £7,128. Total income tax: £14,668.
Employee NIC: 8% on £37,700 (£12,570 to £50,270): £3,016. 2% on £17,821 (£50,271 to £68,091): £356. Total employee NIC: £3,372.
Employee pension at 5% of gross: £3,405, which goes to pension rather than disappearing.
Net take-home pay (excluding pension): £68,091 – £14,668 – £3,372 – £3,405 = £46,646 per year. That is roughly £3,887 per month.
Adding pension: £3,405 goes into your pension pot, so your total earnings including pension are £50,051.
This example uses rolled-up holiday pay. With accrued holiday pay, your weekly take-home is lower during work weeks and higher when you take leave. The annual total stays the same.
How salary sacrifice affects your take-home
Salary sacrifice lets you redirect part of your gross pay into your pension before tax and NIC are applied. You pay income tax and employee NIC on a lower figure. That means more money goes into your pension pot and less goes to HMRC.
Using the example above, say you sacrifice an extra £200 per month into your pension. Your gross pay for tax purposes drops by £2,400. You save income tax at 40% on £2,400 if you are a higher rate payer, which is £960. You also save employee NIC at 2% on £2,400, which is £48. Total saving: £1,008 per year.
At the basic rate, the tax saving is 20%. That is £480 in income tax plus £192 in NIC. Total saving: £672 per year.
The sacrifice goes into your pension, so it is not lost. The net cost of the extra contribution is lower than the headline figure.

How NMW limits salary sacrifice
Your umbrella must keep your hourly rate above the National Minimum Wage after any salary sacrifice. The National Living Wage rate is £12.71 per hour in 2026-27. If your salary sacrifice would take your hourly rate below that, the umbrella has to limit the sacrifice. You cannot sacrifice your way below NMW.
This limit mostly affects contractors on lower assignment rates. A contractor on £350 per day has plenty of headroom above NMW. A contractor on £150 per day may hit the ceiling sooner.
Here is how the limit works. Your umbrella calculates your effective hourly rate after sacrifice. If it falls below £12.71, they reduce the sacrifice to stay compliant. They will tell you the maximum sacrifice amount available at your rate.
If you are near the NMW cap, raise your assignment rate with your agency. That is the fix, not reducing the sacrifice.

Frequently Asked Questions
How is umbrella take home pay calculated?
Start with the assignment rate. Deduct employer NIC (15%), apprenticeship levy (0.5%), the umbrella margin, and holiday pay. What remains is gross pay. Then income tax and employee NIC come off gross pay through PAYE. The result is your take-home.
What is an assignment rate?
The assignment rate is the total amount your agency or client pays your umbrella for your work. It is not your gross salary. Employer costs come out of it before your gross pay is set.
How much take-home pay would a £350/day contractor get in 2026-27?
On roughly 46 working weeks with rolled-up holiday pay and standard assumptions, a £350/day contractor takes home around £46,600 per year net, plus around £3,400 going into their pension pot.
How does salary sacrifice affect umbrella take-home pay?
Salary sacrifice reduces gross pay for tax and NIC purposes. You pay income tax and employee NIC on a lower figure. The saving goes into your pension. At the basic rate, each £100 sacrificed costs you about £73 net.
Why does umbrella take-home pay seem low compared to the day rate?
Employer NIC (15%), income tax, employee NIC, and the umbrella margin all come out before or from your gross pay. A £350/day rate funds all of those. The day rate is not your gross pay.
Can I sacrifice below the National Minimum Wage?
No. Your umbrella must keep your effective hourly rate at or above £12.71, the NLW for 2026-27, after salary sacrifice. If you hit that floor, the umbrella caps your sacrifice at the compliant level.
