Universal credit/ self employment help

good morning, I am trying to help my friend with her universal credit.
she is currently self employed as nail technician and rents a chair. She has a 3 year old son and has a mortgage so no rent element.

She earns around £1300 a month before any of her deductions. I know there’s a minimum income floor required but is that amount before or after and of her outgoings for materials etc?

She’s getting no payment from universal credit at all at the moment. She used to have a business premise earlier this year but unfortunately could no longer afford it so hence why she now rents a chair.
she has previous losses for self employment of around -£7k.

Could some one please work out to what she would be entitled to?

So she would have the following on her claim:

Single over 25

One child who is 3

No rent due to mortgage…

Childcare of around £200 a month

No other elements…

She would then have her income of around £1300 before any expenses.

Hope I’ve explained this correctly.

Thankyou so much.
