I agree with a PP that you don't yet have a handle on what you spend. It's a great start, but I think if you really commit to tracking your spending every month, you will see that you have a lot less/spend a lot more than you think.
For instance, right up there in your OP, you say:
^We have about 12k in debt but about 3k of that is a loan and car finance that is due to be paid off spring next year .
So we have about 10k we need to tackle^
But 12K-3K = 9K, so you did sort of "know" that you owed more than £12K to begin with, but I think you've probably out your head in the sand.
Similarly, Netflix is £7 per month not £6 (£6.99, unless you know something I don't
) and I would bet you half that food budget that you spend more than £200 per month on food & "other groceries" e.g. toilet roll, shampoo, cleaning stuff etc.
You have to be brutally honest and round up rather than down. You might want to spend £50 per week on food, but if your main shop is £50 per week that's actually more per month than £200 (a month is 4.33 weeks, so £50 x 4.33 = £216.50) and then what about the odd corner shop stop for milk & bread etc.? It all adds up really quickly.
Again, petrol - is that £40 per week? That's actually £173.20 per month (not £160).
You need to figure out how much you spend on the following, and put some money aside for them every month. Make a guess if you're not sure - it might not be "right" but it will be a start:
Presents (birthdays & other celebrations)
Christmas
Haircuts
Clothes & shoes/school uniform
Insurances (car, house etc.)
Car repairs & maintenance (MOT, new tyres etc.)
Household "stuff" (garden, new bins, replacing batteries & lightbulbs etc.)
Pets? (annual boosters, vet treatment. toys etc.)
Entertainment (cinema, pub, days out etc.)
Eating out/takeaways/coffee habit etc (be honest!)
Emergency "oh shit" fund (boiler repair, tax credits stopped - anything you can't predict but might need some money put by to help with.)
In "utilities" have you accounted for just gas & electric, or have you got water rates in there too?
Once you have ABSOLUTELY EVERYTHING listed, you can start to see - is it worth it to pay £X per month if we could cut it down to £Y instead? Then you can make a plan.
The first step is the worst. You can get good at this, and the skills you'll learn will benefit not just you right now, but your DC in the future.
Good luck!
