DP and I pretty much share out the paying of our costs, with perhaps a bit of accounting for the fact that we’re on different incomes. The main costs, mortgage, bills, shopping, childcare etc. we broadly split by income, so we have direct debits set up and DP pays a bit more than me. For more discretionary things like clothes, meals out, toiletries, memberships etc. we sometimes pay for our own and sometimes get for both, for example the Amazon account is in DP’s name and we both just get things from there when needed. If I’m doing a clothes shop from H&M DP will add a few bits and I’ll just pay to save on the cost of two deliveries.
Savings are also seen as broadly common e.g. we’re about to move and I’m putting in a bit more than DP just because I’ve ended up with more in the bank, and DP covered some other big costs from their account earlier in the year.
We don’t really keep count, or get pissed off if one pays for more than the other on a particular month as we see the money as our shared money, that’s financing our shared life, regardless of whose income it originally came out of. DP also doesn’t expect me to spend less on discretionary things because my income is a bit lower. It probably helps that neither of us has exorbitant hobbies and that we have a broadly similar view of what’s reasonable to spend on what.
I thought until recently that this is how most couples were, (assuming they are in a committed and happy relationship - different if things are rocky of course) but a few friends have been quite shocked and said that no, they keep their finances very separate. And pay 50 50 or some other carefully calculated split for shared cost like rent / mortgage and then pay for everything else out of their own salary and have their own savings.
So what do you do and why?
