All figures are per month. Universal Credit is worked out from your UC net earnings — gross pay minus Income Tax, National Insurance and eligible pension contributions. Student loan repayments reduce your take-home pay but not the earnings used for UC.

Where the extra pay goes

Income Tax & National Insurance−£165
Extra take-home pay+£424
Universal Credit change−£233
Real change in household income+£191

Based on the details entered, your estimated household income increases by £191 a month — you keep about 32p of every extra £1 of pay. For each extra £1 of UC net earnings above your work allowance, Universal Credit falls by 55p, so your combined earnings and Universal Credit rise by 45p before other household costs. This estimate does not include travel costs, changes to Council Tax Reduction, other benefits or how your pay dates fall — check your wider situation before deciding.

Why your Universal Credit changed

On the new hours:

Maximum Universal Credit£1,329
Net earnings used£1,510
Work allowance−£427
Earnings subject to the taper£1,083
55% taper reduction−£596
Estimated Universal Credit£733
Watch your pay dates. Universal Credit is worked out each monthly assessment period. If you are paid every four weeks, one period a year may include two paydays; if you are paid fortnightly it may include three, or five if you are paid weekly. That period is assessed on higher earnings, which can temporarily reduce or stop your UC. Your award usually rises again when fewer wages are counted.

Frequently asked questions

Am I better off working more hours on Universal Credit?

Almost always, yes. Universal Credit is designed so work pays: above your work allowance it falls by 55p for each £1 of net earnings, so your combined earnings and UC still rise by 45p. Within this calculation, higher earnings do not reduce your combined take-home pay and Universal Credit — though extra childcare, travel costs, the benefit cap or a change to Council Tax Reduction can affect your wider position. Enter your current and new hours above to see your estimated real gain.

How much of each extra £1 do I actually keep?

Once your earnings are above any work allowance, and before Income Tax or National Insurance applies, each extra £1 normally raises your combined earnings and UC by 45p (the 55% taper takes the rest). If part of the increase still falls within your work allowance, your average keep rate can be higher — that is why going back to work from nothing can keep more than 45p. Once you pay 20% Income Tax and 8% National Insurance too, you keep roughly 32p of each extra gross £1. The calculator uses your exact starting and new earnings to work this out.

Does Universal Credit use gross pay or net earnings?

It normally uses your UC net earnings: gross taxable pay after Income Tax, National Insurance and eligible pension contributions. Student loan repayments are not deducted for this purpose — so a student loan lowers your take-home pay but not the earnings used for UC, while paying into a pension lowers both and can increase your UC.

What is the work allowance?

It is the amount you can earn each month before the taper starts. For 2026/27 it is £427 if your Universal Credit includes help with rent, or £710 if it does not. You only get a work allowance if you have children or a limited capability for work; otherwise the taper applies from your first pound of earnings.

Will two paydays in one month reduce my Universal Credit?

They can. UC is calculated for each monthly assessment period, so if you are paid weekly, fortnightly or four-weekly, two paydays can occasionally fall inside one period. That month is assessed on higher earnings and your award drops, then recovers the following month. A bonus or a payday shifted by a weekend can have the same temporary effect.

What does this calculator not include?

It covers Universal Credit, Income Tax and National Insurance only. It does not model Council Tax Reduction, the benefit cap, Local Housing Allowance rent caps, sanctions, debt deductions, surplus earnings or transitional protection. For a full check of everything you could claim, use the GOV.UK benefits calculators or contact Citizens Advice.

A simplified estimate on 2026/27 rates that combines take-home pay with a Universal Credit estimate. It assumes a single earner unless you add a partner's pay, uses a standard tax code, and does not model the benefit cap, Local Housing Allowance limits, Council Tax Reduction, sanctions, surplus earnings, or how each assessment period is reported.
