My monthly income (have included tax creds, child benefit etc)- £1200
DPs- £2400
Outgoings are £2390 including rent, council tax, childcare, debt, food.
If we split it 50:50 then I have £5 a month to pay my car insurance, phone bill or buy stuff for me.
I'm crap with percentages but we have said we will put an equal percentage of income in each to cover outgoings and what's left is ours individually.
How do I work this out fairly? I'm PT, DP is FT if that makes a difference and we have 3 DCs and DSD EOW.
