We do exactly what you guys are doing, OP! But we also benefit from earning very similar salaries. We are also in jobs which pay bonuses and we always talk about how much we are getting etc so the other person knows, but the bonus money we save ourselves (not joint), we are both saving for a house deposit. When we get paid each month we pay the same amount into our joint card (JC), and everything for the house, groceries, our toddler, eating out together, purchases for the house, holidays etc we put on the JC. Everything else we are spending (like own lunches with work, separate nights out, my makeup/clothes or his golf for instance) will be on our own cards. Why would we expect the other person to pay for that?! I might want to save more one month and he might want to pay for a golf membership for the summer, so I don't see how other people with complete joint finances would be happy with that.
We have another baby on the way (due in 2 weeks!) and this time (just like last time) I'm taking 6 months leave (I live abroad so a quarter of this will be full paid, quarter half paid, one month will be saved annual leave so I get paid, last two months unpaid). Needless to say I'll be much worse off financially during mat leave so my husband will obviously step up and pay the rent and put more money on the JC so I'm not losing out just because I'm on mat leave. He did this last time and it wasn't even a discussion, just an equal thing to do! He also paid for a holiday we took by the end of my mat leave as I didn't have an income.
I love having my independence when it comes to money but at the same time share fairly with DH. We are both fairly career driven and I can't see how pooling all money where both salaries goes into the same account is good as you always see what the other person is buying/spending - what if he wants to treat me to a date (he usually does, for instance birthdays, date nights, anniversaries etc) or if we want to buy each other presents, how is that special if it comes out of the joint account? And when we can see what present the other person is buying (from where).
I do have to mention that I have an extremely
Negative experience from salaries going into same account (ex fiancé), I was super naive with money (I was also the high earner) but thought everything should be equal, all our savings were together and we both had access - It turned out that he was a narcissist and a cheater, and when I found out he transferred all our savings (90% money I had put in) to his own account and there was no way I could get that back when we broke up. There was also a lot of built up resentment as he used to treat "all the boys" to rounds at the pub and dinners out with our (mostly my) money and he could live a fantastic lifestyle he barely contributed to. I had no savings after that relationship and I've learned the hard way how important it is with joint money as well as own money, I'll never put myself in that position again.
I trust my DH completely but I don't see the benefit in the salaries going into the same account and to share absolutely everything financially. It is good to keep some independence.
Again, I know we benefit from earning similar salaries so neither of us are worse off doing it this way, but he is about to change jobs now where he will earn 30% more than me, so he will naturally pay more rent and put more into the JC each month so I won't be worse off than him financially.
