It depends on whether you have children and what your hourly wage (equivalent if you are salaried) is.
£498.89 is the allowance for a couple over 25 years old.
If you were both working 35 hrs per week, you'd earn £525 per week, which is £27,300 per year,
so £2,275 per month before tax, etc., and £1810.93 after tax, etc.
If you don't need help with housing costs, you get an earnings disregard of £397.
£1810.93 - £397 = £1413.93.
Then they still deduct 63p for every £1 of the remainder from your benefit:
Deduction: £1413.93 x 0.63= £890.76
Total benefit:
£498.89 - £890.76= £-391.89
So as a couple without children, working full time on minimum wage, without rent assistance you wouldn't qualify for UC.
You can follow the same steps to look at your needs, but be aware that you'd have to sign up to looking for more work or different work to bring you both up to 35 hours of NMW work. However, if your work now pays over the NMW, you'll have to do some maths to work out what that equates to in terms of the NMW. You might find that your DP's 30 hrs actually equates to 33 hours of NMW, for example.
