Partner moving in - how to split costs?

[PeachesMao]

Hi All,

My parter and I will be moving in together in the next few months, and I'm trying to get my head around how to work things out fairly - would appreciate some views on the finances!

I'm a mum to one (in Ireland so benefits etc are different to UK).

I currently earn €1850 per month, and receive €650 hb per month. I also receive benefits of €38 per week.
Rent is €1300 pm.
When my partner moves in, my wages will drop to €1700 per month as I'll lose my single parent tax credit, and I'll no longer be eligible for the €38 per week, or the hb obviously.
All fine, but it does mean my income will have a net drop of about €300 euro.

He gets paid weekly, roughly around €500.

He wants to ensure that I'm not left worse off due to him moving in, but I can't figure out what's a fair split, given the difference in income

Also the fact I get paid monthly and he gets paid weekly is throwing me as I'm not exactly sure how you calculate the difference - maths is not my strong point

Hoping someone can give me some pointers

Thanks

All money into one pot and you each get half the remaining spends?

you need to times your wage by 12 and his by 52 so that you get an annual figure for you both

You need to work out the out goings

Rent £1300
Electric
Water
TV

Etc

Technically he'll make up half of the rent - so you haven't lost housing benifit but gain his contribution

Oh damn I knew I left important info out.

I have additional expense to him (debt, car), so don't think it would be right splitting things down the middle just yet.

Total bills (inc food) and rent is 1900 per month

I can’t help on the maths (sorry!) but I will warn you that when I had the same dilemma, I had comments suggesting I should immediately add him to the mortgage; then that I was clearly with him for his money; and also that he was a cocklodger.

Just FYI

Thanks for all your replies!

So if he earns roughly 2200 per month and I'm on 1700 - how would we work out proportional contribution?

Sorry I really am very bad at maths!

Thanks for the heads up Shirley

Personally I would:

Calculate his income per month (in this case €500 X 52/12)

Calculate your monthly outgoings that you both benefit from, not inc your child's element of your outgoings.

Each pay half toward those joint outgoings.

How does that leave you?

I'm assuming there's Irish benefit calculators you can check if you'll definitely lose all your benefits?

Hmmmmm

Ok so to take 1900 is the joint outgoings. (I've kept the child benefit and outgoings out of that)

I'm left with 750, he's left with 1150.

No benefit cacluators here unfortunately but I've checked all relevant websites and I definitely lose everything.
He is saving at the mo towards an engagement ring also, and when we're married it will be one pot but struggling to get my head around my income dropping so much in the interim

Is that more or less than you had left over before?

Oh after working it out, its actually roughly the same

I did warn that my maths was bad!

I think I've just been looking at the income drop and panicking.

Thanks everyone for your input!

U ok then?
