On Universal Credit you keep about 32p of every extra pound you earn. Not 55p — 32p, once Income Tax and National Insurance have taken their share first. That is a higher marginal rate than a millionaire pays. Put your own situation in below and see exactly what an extra shift, or a pay rise, is actually worth to you.

Your gross pay a month Before any deductions. We work out the tax and National Insurance for you. Universal Credit is worked out monthly, so this page uses months.

Who is in the household?

Your partner’s gross pay a month

Children you claim for Having a child is what unlocks a work allowance — an amount you can earn before your Universal Credit is touched at all.

Health condition or disability

I claimed before 6 April 2026, or my condition is severe or terminal This matters a lot. The health element was split in two on 6 April 2026: £429.80 a month if you are protected, £217.26 if you are not.

I get help with rent through Universal Credit This halves your work allowance, from £710 to £427.

Housing element a month

Where do you live? Sets the benefit cap, which is higher in London, and the income tax bands — Scotland has its own. Northern Ireland uses the same tax rates as England.

Someone here gets PIP, DLA or Attendance Allowance This exempts your household from the benefit cap entirely.

I care for someone at least 35 hours a week Adds the carer element, and brings in the Carer’s Allowance earnings limit — which is a cliff edge, not a taper.

I claim Carer’s Allowance

Why you keep so little

Universal Credit goes down by 55p for every £1 you earn above your work allowance. That 55p is taken from your pay after tax and National Insurance, not before — so the two stack up:

You earn an extra £100. Income Tax takes £20 and National Insurance takes £8, leaving £72. Universal Credit then drops by 55% of that £72, which is £39.60.

You keep £32.40. That is an effective rate of 68% — higher than the 45% top rate of Income Tax.

Below the tax threshold it is better, but not by as much as people expect: with no tax and no National Insurance to pay you still keep only £45 of every £100.

The work allowance you may not have been told about

A work allowance is an amount you can earn each month before Universal Credit is reduced at all. There are two, and one very large catch:

£710 a month if you have children or limited capability for work, and you do not get help with rent through Universal Credit.
£427 a month if you have children or limited capability for work and you do get help with rent.
Nothing at all if you have neither children nor limited capability for work. The 55% taper starts at the very first pound you earn.

That last one catches people out constantly. A single person with no children and no health condition has no disregard whatsoever. Earn £10 and your Universal Credit falls by £5.50 the same month.

The benefit cap, and the one threshold worth chasing

The benefit cap limits total benefits to £1,835 a month for couples and lone parents outside London (£2,110.25 in Greater London), or £1,229.42 for a single adult without children (£1,413.92 in London). It is frozen for 2026/27.

But earning £881 a month after tax and National Insurance removes the cap completely. That makes it the mirror image of a cliff edge — a step up. For a capped couple with four children and high rent, going from £880 to £881 a month is worth £899 a month on our figures. One pound of pay, nearly £10,800 a year.

You are also exempt from the cap, whatever you earn, if you have limited capability for work and work-related activity, if you care for someone with a disability, or if anyone in your household gets PIP, DLA, Attendance Allowance or Carer’s Allowance. If your earnings have just dropped there is also a nine-month grace period.

The two-child limit is gone

Since 6 April 2026 the child element is paid for every child. The Universal Credit (Removal of Two Child Limit) Act 2026 became law on 19 March 2026. If you have three or more children and were told years ago that you would only be paid for two, that is no longer true — and it is worth £303.94 a month per extra child, about £3,650 a year each. A family with four children gets £607.88 a month more than the old rules allowed. Many online calculators have not caught up.

Carer’s Allowance is a cliff, not a taper

This is the sharpest edge in the whole UK benefits system, and it is the one worth checking before you agree to any extra hours.

If you earn £204 a week or less after allowable deductions, you get the full £86.45 a week.

If you earn £204.01, you get nothing.

One penny costs you £4,495.40 a year. There is no taper, no partial rate and no warning — and because it is assessed weekly, a single extra shift in one week can do it.

Overpayments happen this way constantly: people drift over the limit without realising, and are asked to pay back months of Carer’s Allowance. If you are anywhere near £204 a week, check before you take the hours, and remember that some things can be deducted from your earnings first — ask the Carer’s Allowance Unit.

How this compares with the Republic

We model both systems, and they fail in opposite ways. In Ireland there are genuine cliff edges and dead zones — stretches where working more leaves a household with less money, and single euros that cost tens of euros. Universal Credit has neither: it tapers smoothly all the way, and on our figures there is no point at which working more makes you worse off.

Universal Credit does not trap you. It just makes work barely worth doing. Carer’s Allowance is the glaring exception — and it is a harder edge than anything in the Irish system. See the Irish version of this tool →

What this does not do

This is a guide to the shape of the rules, not a decision. Only the DWP (or the Department for Communities in Northern Ireland) can decide your entitlement.

It models Universal Credit elements, the work allowance, the 55% taper, the benefit cap, Income Tax, National Insurance and the Carer’s Allowance earnings limit. The cap is applied to Universal Credit only — Child Benefit also counts towards it and is not modelled, so a capped household may lose slightly more than shown.

It does not model childcare costs in detail, savings over £6,000, transitional protection when moving from old benefits, or sanctions. It assumes a standard Personal Allowance and tax code.

If you are close to the Carer’s Allowance limit, check with the Carer’s Allowance Unit or an adviser (Citizens Advice, or Advice NI) before you change your hours.

Common questions

Can I get Carer's Allowance and the State Pension?

Not usually both in full — they "overlap". But it's still often worth claiming, because an "underlying entitlement" to Carer's Allowance can increase Pension Credit through the carer's addition.

What counts towards the 35 hours?

Practical care and supervision — helping with washing, dressing, medication, cooking, getting around, and keeping the person safe. It doesn't have to be one household or one stretch.

What is the earnings limit?

£204 a week after tax, National Insurance and some allowable expenses. It's a hard cliff-edge — a pound over and you lose all of it — so check the exact figure carefully.

Does claiming affect the person I care for?

Sometimes. If they get a severe disability premium, your claim could reduce it. Check the combined effect before you claim so nobody's worse off overall.
