Umbrella take-home pay can feel confusing at first. The day rate your agency gives you is not the amount you receive. The umbrella takes out employer costs before your gross pay is set. Then tax and NIC come off the gross. This guide shows the full process in plain terms.
DASA Umbrella holds dual accreditation from FCSA and Professional Passport. Both are leading compliance bodies for umbrella companies. DASA is an umbrella payroll company with both accreditations.

How does umbrella pay get calculated?
Umbrella take-home pay starts with your assignment rate. The umbrella then deducts employer NIC at 15%, the apprenticeship levy at 0.5%, its margin, and holiday pay. What is left is your gross pay. Income tax and employee NIC then come off through PAYE. The amount left after that is your 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 focus on stage two. Stage one is where the bigger cuts happen. Employer NIC alone takes 15% of earnings above £5,000. That takes a big chunk off before tax starts.
What is an assignment rate?
The assignment rate is the total amount your agency or client pays your umbrella for the work. People also call it the contract rate or the umbrella rate. It is not your gross salary. It is the amount the umbrella uses to cover costs. Your gross salary is what remains after those 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.
Two contractors can have the same day rate and still take home different amounts. Pension contributions, holiday pay methods, and umbrella margins all change the result.
What gets deducted before you’re paid?
Stage one deductions come out of the assignment rate. These are employer-side costs:
- Employer NIC, 15% on earnings above £5,000 a year
- Apprenticeship levy, 0.5% on earnings above £15,000 a year
- Umbrella margin, a fixed weekly or monthly fee
- Holiday pay, either rolled up at 12.07% or accrued until you take leave
Stage two deductions come off your gross pay through PAYE:
- Income tax, at 20%, 40%, or 45%
- Employee NIC, at 8% up to £50,270, then 2% above that
- Employee pension contribution, usually 5% minimum under auto-enrolment

A worked example at 2026-27 rates (£350/day)
Here is a worked example for a contractor on £350 per day, working five days a week. The assumptions are 46 working weeks a year, rolled-up holiday pay, tax code 1257L, a 5% employee pension contribution, and no salary sacrifice.
Annual assignment rate: £350 x 5 days x 46 weeks = £80,500
With rolled-up holiday pay at 12.07%, £80,500 breaks down into £71,830 base pay and £8,670 holiday pay.
Using £71,830 as the base for employer cost calculations, employer NIC starts after the £5,000 secondary threshold. Employer NIC at 15% on (£71,830 – £5,000) is £10,025. The apprenticeship levy at 0.5% on (£71,830 – £15,000) is £284. An example umbrella margin of £125 a month adds £1,500. Total employer deductions are £11,809.
Gross pay before PAYE: £71,830 – £11,809 = £59,421
Gross pay including holiday pay: £59,421 + £8,670 = £68,091 a year
Stage two starts with PAYE on £68,091. The personal allowance is £12,570, so no tax applies there. Basic rate tax at 20% on £37,700 is £7,540. Higher rate tax at 40% on £17,821 is £7,128. Total income tax is £14,668.
Employee NIC is £3,372. That is £3,016 at 8% and £356 at 2%.
A 5% employee pension contribution adds £3,405. That goes into your pension, not to HMRC.
Your net take-home pay, excluding pension, is £46,646 a year. That works out at about £3,887 a month.
Including the pension, total earnings come to £50,051.
This example uses rolled-up holiday pay. With accrued holiday pay, your weekly take-home is lower while you are working. It rises when you take leave. The yearly total stays the same.
How salary sacrifice affects your take-home
Salary sacrifice lets you move 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. More goes into your pension and less goes to HMRC. It is one of the easiest ways to boost the value of your umbrella pay.
Using the example above, if you sacrifice another £200 a month into your pension, your gross pay for tax purposes falls by £2,400. You save £960 in income tax at 40% and £48 in employee NIC at 2%. The total saving is £1,008 a year.
At the basic rate, the tax saving is 20%. That is £480 in income tax plus £192 in NIC. The total saving is £672 a year.
The sacrifice still goes into your pension. It is not lost. Your net cost is lower than the headline amount.

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 is £12.71 per hour in 2026-27. If your sacrifice would take your rate below that, the umbrella has to cut it back. You cannot sacrifice your way below NMW.
This limit mainly affects contractors on lower assignment rates. A contractor on £350 per day has plenty of room above NMW. A contractor on £150 per day may hit the cap sooner.
Here is how it works. Your umbrella works out 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 amount you can sacrifice at your rate.
If you are close to the NMW cap, ask your agency to raise the assignment rate. That is the fix.

Frequently asked questions
How is umbrella take-home pay calculated?
Start with the assignment rate. Deduct employer NIC at 15%, the apprenticeship levy at 0.5%, the umbrella margin, and holiday pay. What remains is gross pay. Then income tax and employee NIC come off through PAYE. The amount left 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 a year net, plus around £3,400 going into the pension pot.
How does salary sacrifice affect umbrella take-home pay?
Salary sacrifice lowers gross pay for tax and NIC purposes. You pay income tax and employee NIC on a smaller figure. The saving goes into your pension. At the basic rate, each £100 sacrificed costs about £73 net.
Why does umbrella take-home pay seem low compared to the day rate?
Employer NIC at 15%, income tax, employee NIC, and the umbrella margin all come out before or from your gross pay. A £350/day rate has to cover all of them. 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 in 2026-27 after salary sacrifice. If you hit that floor, the umbrella caps your sacrifice at the compliant level.
