How Universal Credit is calculated.
Universal Credit looks complicated because it bundles six legacy benefits into one calculation. Once you separate the maximum entitlement, the earnings taper and the savings rule, it becomes much clearer. Here's the full formula for 2025/26, with three worked examples.

The formula in one sentence
Your monthly UC = (Maximum amount) − (55% of earnings above the work allowance) − (other income) − (tariff income from savings).
Everything else is just figuring out what each of those three numbers should be. Let's break them down.
Step 1 — Your maximum amount
Start with the standard allowance, then add any elements that apply to your household.
Standard allowance (2025/26 monthly rates)
| Household | Standard allowance |
|---|---|
| Single, under 25 | £316.98 |
| Single, 25 or over | £400.14 |
| Couple, both under 25 | £497.55 |
| Couple, at least one 25 or over | £628.10 |
Elements you can add
- Child element: £339.00/month for a first child born before 6 April 2017, otherwise £292.81/month per child. Two-child limit applies to third and subsequent children born after 6 April 2017 (with exceptions).
- Disabled child element: £158.76/month (lower rate) or £495.87/month (higher rate, if the child gets the highest rate care component of DLA or enhanced PIP daily living).
- Housing element: your eligible rent, capped by Local Housing Allowance for private rent or reduced by the "bedroom tax" for social rent. There's no housing element if you own your home outright; some help is available with mortgage interest through Support for Mortgage Interest, but it's a loan, not a benefit.
- Carer element: £201.68/month if you meet the carer rules (35+ hours/week, caring for someone on a qualifying disability benefit).
- Limited capability for work (LCW): nil for new claimants (LCW alone no longer pays an element since April 2017).
- Limited capability for work-related activity (LCWRA): £423.27/month.
- Childcare element: up to 85% of registered childcare, capped at £1,031.88/month (one child) or £1,768.94/month (two or more).
Step 2 — Earnings deductions
UC reads your earnings from HMRC's PAYE system if you're employed. For self-employed people, you report monthly earnings to your UC journal.
The work allowance
If you have a child or limited capability for work, you have a work allowance — the amount you can earn each month before UC starts being withdrawn:
- £411/month if you receive the housing element.
- £684/month if you don't receive the housing element.
If you have no children and no limited capability for work, you have no work allowance: every £1 of earnings reduces UC from the first £1.
The 55p taper
Above the work allowance, UC is reduced by 55p for every £1 of net earnings. "Net" here means after tax, National Insurance and 100% of any pension contribution.
So if you earn £1,000/month net above your work allowance, your UC is reduced by £550. You keep £450 of those earnings — a 45% retention rate before you consider losing other passported help like free school meals.
Step 3 — Other income and capital
Three more things get subtracted from your maximum UC:
- Other benefits (Carer's Allowance, contribution-based ESA/JSA, certain widow's benefits) are deducted £1-for-£1.
- Occupational and personal pensions are deducted £1-for-£1.
- Tariff income from savings: if your household has £6,000–£16,000 in capital, UC adds £4.35/month of "tariff income" for every £250 (or part) above £6,000. Above £16,000 in savings, UC stops entirely.
Worked example 1 — Single parent, 2 children, part-time work, renting
Layla, 34, single, two children, works 20 hours/week at £12.50/hour, rents privately at £650/month, has £1,200 in savings.
- Annual gross income ≈ £13,000. Net ≈ £12,650/year → £1,054/month net.
- Standard allowance (25+, single): £400.14
- Child element (1st child, post-2017): £292.81 + (2nd child) £292.81 = £585.62
- Housing element: £650.00 (under LHA cap)
- Maximum UC = £1,635.76/month
- Work allowance with housing: £411 → earnings above allowance = £643
- Taper at 55% = £353.65 deducted
- Savings under £6,000 → no tariff income
- UC award ≈ £1,282/month
Plus Child Benefit (£187.10/month) on top, plus likely full or partial Council Tax Reduction in many councils. Total household monthly support: ~£1,560.
Worked example 2 — Couple, both unemployed, renting in London
Mark and Pavel, both 28, no children, unemployed, renting a one-bed in Tower Hamlets for £1,400/month. No savings.
- Standard allowance (couple, 25+): £628.10
- Housing element: £1,400.00 (within LHA for inner London 1-bed)
- Maximum UC = £2,028.10/month
- No earnings, no other income, no tariff income
- UC award = £2,028.10/month
But: this brings their annual benefits total to over £24,000. The Benefit Cap for couples in Greater London is £25,323/year. Add a small Council Tax Reduction and they're close to — but not over — the cap, so no cap deduction yet.
Worked example 3 — Family of four, no earner, outside London
Hannah and Tom, both 38, four children (born 2018, 2020, 2022, 2024), renting a 4-bed in Liverpool for £1,100/month. No savings, no earnings, no disability.
- Standard allowance (couple, 25+): £628.10
- Child element: £292.81 × 2 = £585.62 (two-child limit caps it at two)
- Housing element: £1,100.00
- Maximum UC = £2,313.72/month = £27,764.64/year
Plus Child Benefit for all four kids (£26.05 + 3 × £17.25 = £77.80/week = £4,045.60/year). Total before cap: £31,810/year.
Add Council Tax Reduction (~£2,100/year). Grand total: ~£33,910/year. The Benefit Cap for couples/families outside London is £22,020/year — so a Benefit Cap reduction of nearly £12,000/year applies. The shortfall is taken first from the housing element of UC, leaving the family with a real housing payment problem unless someone in the household qualifies for an exemption (e.g. PIP for a child).

Common edge cases
- You started a UC claim mid-month: your first "assessment period" runs from the day you applied. You don't get pro-rated for "partial months."
- You're paid four-weekly or weekly: UC counts each calendar month's pay separately. If two pay dates fall in one assessment period, that month's UC drops sharply.
- You're a director of a limited company: UC treats you as self-employed for the purposes of the Minimum Income Floor — even if your company didn't pay you anything that month.
- You inherited money: capital over £16,000 disqualifies you immediately. Spend-down rules apply if you reduce your savings "deprivation" rules — get advice before transferring money.
