Can you clean up the figures for outgoings? Some are listed per week (child care), some are listed per month (mortgage) and some seem to be in totality (family loan). Similarly, E25 Gym - is this per month per person or what? It's hard to know what are fixed monthly or weekly costs, suggest you edit original post to make it easy to understand. List each expense clearly by amount and by timeframe. How much are you paying per month to your family loan? Is that included in the monthly loan repayment figure?
1) Stop Borrowing
Yes you need to stop borrowing money, from anyone IMO (family, bank, credit union, credit card. I assume you have cut up your credit card at this point?
2) Understand Interest and Cost of Credit
Also important missing information, what is the interest rate on your credit card balance? In other words, how much interest are you paying on this loan per month? How much are you paying off the outstanding balance per month? (This is in effect another loan).
Please find out for sure and find out if it's fixed, variable or what. Also, what are the interest rates on two personal loans? Assuming mortgage rate is actually 2.5 percent, forget overpayment. You need to clear high interest debts first.
3) Separate Needs from Wants/Nice to have spending
I echo other posters, your grocery+broadband+sky+phone bills seem crazy high. . You need to separate groceries (required) from eating out, eating in takeaways, lunches out, coffees out. Depending on that split, your *actual* groceries might only be a reasonable E800 per month, which sounds do-able me, saving you a whopping E700 per month (of non grocery spending).
For example, "lunch a couple of times a week" could be costing you 2 people * 2 times per week * 10 euro per person = 40 per week * 4 = 160 month (could be double that or half that depending on what lunch is for you).
Takeaways once a week for 4 must be E40 quid per week so another E160 per month.
Finally, eating out 2/3 times a month for 4 people is surely E200-300.By that estimate you're spending around 500-600 per month eating food you don't cook yourself. If you're serious about this then id suggest stop eating out, stop getting takeaways, make your own lunch and stop getting coffees for a month and see how much you save.
4) Hidden Spends?
I see no mention of cigarettes or alcohol. Do either of you drink or smoke? If so, you must factor in monthly spending on these expensive discretionary items, and obviously reduce them.
5) Child Benefit?
My understanding is that Child Benefit is €140 per month for each child? Where is this E280 per month going? I don't see it being added to the effective take home pay per month figure.
