Universal Credit does not stop the moment you start working — instead it tapers away gradually as earnings rise. This calculator applies the DWP’s 55p taper to your net earnings above the work allowance and shows the resulting UC payment and your total monthly income, so you can see how extra hours actually affect your budget.
How it works
Universal Credit is a monthly calculation:
earningsAboveAllowance = max(0, netEarnings − workAllowance)
reduction = earningsAboveAllowance × 0.55
ucPayment = max(0, maxUC − reduction)
totalIncome = ucPayment + netEarnings
The work allowance is £673 if your UC does not include housing support, £404 if it does, and £0 if you have no children and no limited capability for work. Earnings within the allowance do not reduce UC at all.
Example and notes
Suppose your maximum UC is £900, you net £1,200 a month, and your work allowance is £673. Earnings above the allowance are £527, so the taper removes £527 × 0.55 = £289.85. Your UC payment is £900 − £289.85 = £610.15, and your total income is £610.15 + £1,200 = £1,810.15.
Notes: because you keep 45p of every taxed pound above the allowance, working almost always increases total income. The benefit cap, capital above £6,000, and deductions for debts or advances can change the outcome, so treat this as an estimate rather than an official award notice.
