- Earnings are the biggest factor: after any work allowance, net wages reduce Universal Credit by 55p for every £1.2
- Some benefits count as unearned income and cut Universal Credit pound for pound, including new-style ESA, new-style JSA and Carer's Allowance.1
- Several payments are ignored completely, including PIP, DLA, Attendance Allowance, Child Benefit and Discretionary Housing Payments.1
- Savings are separate from income: below £6,000 they are ignored, and £16,000 or more stops Universal Credit.3
- Between £6,000 and £16,000, each £250 above £6,000 adds £4.35 a month of assumed tariff income, not real cash.3
Earned income: wages after the work allowance
For working-age Universal Credit, earnings matter most. The calculation uses your net wages, and if your household qualifies for a work allowance, that slice is ignored before anything is tapered.2
Everything above the work allowance reduces the award by 55p in the pound. There is no work allowance for households without a child or a limited capability for work element, so for them the taper starts from the first pound earned.2
Unearned income: what counts pound for pound
Unearned income is not tapered; it is deducted in full. That means £1 of counted unearned income usually cuts Universal Credit by £1.1
The common ones are new-style (contribution-based) ESA and JSA, Carer's Allowance, and most pension income, including occupational and private pensions. So a works pension is counted in full even though wages get the more generous taper treatment.
What Universal Credit ignores completely
Several important payments do not count as income at all. Disability benefits are ignored: PIP, DLA and Attendance Allowance never reduce a Universal Credit award. Child Benefit is also ignored as income, and so are Discretionary Housing Payments and most one-off payments like the Social Fund.1
Child Benefit is a common source of confusion. It does not reduce your Universal Credit directly, but it can still count towards the Benefit Cap, which limits total household benefits. That is a cap issue, not an income-taper issue, and the two get mixed up a lot.
Worked example: how savings become tariff income
Capital is treated separately from income, but it can still cut your award through tariff income. Take someone with £10,000 in savings. Only the amount above £6,000 is counted, and it is turned into assumed income in complete £250 bands:
| Savings | £10,000 |
| Amount above the £6,000 disregard | £4,000 |
| Complete £250 bands (£4,000 divided by £250) | 16 |
| Assumed tariff income (16 x £4.35 a month) | £69.60 |
So £10,000 of savings is treated as £69.60 a month of income, which is then deducted from the award. It is not real money changing hands; it is an assumption the rules make. At £16,000 the tariff stops mattering because savings of £16,000 or more end Universal Credit entirely.3
The bit that trips people up: pension-age rules are far kinder. Pension Credit ignores the first £10,000 of savings and has no upper cut-off, so the same savings that end a Universal Credit claim can leave Pension Credit fully intact.
Why the definition matters when an estimate looks wrong
If a benefit estimate looks lower than you expected, the cause is usually how a particular income or asset is being treated rather than the headline rate. A works pension counted in full, Carer's Allowance deducted pound for pound, or savings just over £16,000 can each change the answer completely.1
When in doubt, check the income and capital treatment for the specific benefit, then re-run the calculator with the corrected figures. Tax charges like HICBC use adjusted net income, a different concept again, so keep those separate from the means-tested rules here.
