Ask HN: How do you structure your shared finances with your spouse/partner

68 points by sbolt ↗ HN
My fiancé and I are getting married next year and have started to think about how we’ll structure our finances together.

How do you structure your day to day spending? Do you have a joint checking/savings/credit card setup, keep things separate or a hybrid approach? We’re based in the US and want optimize for simplicity.

If you want simplicity, go for a joint checking and savings, if there's a personal goal to be saved for by one of you, see if your bank offers 'vaults' that we can squirrel money away until you can purchase the camera or car part or whatever it is. Keeping most things in one place generally maximizes simplicity.
Thank you. The vaults idea is cool, it would be nice to have some discretionary money for small personal projects.
Joint account for daily stuff (I guess that’s checking) plus a joint savings for big things, rest is separate. We pay in an agreed fixed amount each month, which needs to be semi regularly raised lately due to inflation etc etc…

We just continued with our existing accounts, except that one of us now has a savings account which we both pay any surplus into each month. Works for us.
Joint checking account, credit card for each of us with good rewards for all spending, YNAB for budgeting with a category for each of us for our discretionary spending.
It’s not perfect, but I’m a strong believer in separate checking accounts at the same bank

For large items we’ll transfer back and forth as needed and one person makes the payment.

My partner and I have very different spending habits, and seeing that line-by-line would cause daily friction.

Having them separated gives us both discretion and autonomy.

We have two joint checking accounts and three* joint credit card accounts, one of which is logically "mine" and one which is logically "hers" and we freely flow money between them on the rare occasions when it's needed, but day-to-day we have clear single-user management (to avoid overdrafts, spot anomalies, etc.).

We have "calibrated" the direct deposit amounts to minimize the need to move money across the accounts. If money "backs up" in one or the other, we move it into investments, but month-to-month, practically everything is on autopilot.

I think that's about as operationally simple as it gets, which was also a huge priority for us.

Savings and investments are all consolidated and jointly-owned wherever possible and I maintain a periodic (slightly more than quarterly) update of that manually by looking at the Vanguard, Etrade, Fidelity, etc accounts.

* The third credit card account is a Chase Amazon account for the better cash back on that card. It's only used for Amazon, so it's easier to spot anything unusual.

Same here. I have some friends with clearly separated accounting, and they have constant discussions of the kind I definitely don't need. Mind you they are not fighting, just arguing what should go where. I know I would have worse discussions in case of a divorce, but I'll keep them for that case.
It helps that we're pretty compatible in terms of spending habits. I'm more of a cheapskate, but we're both well aware of the math of savings/retirement and neither of us spends stupidly in the other person's opinion.

If a heavy saver marries a heavy spender, I'm not sure that there exists an arrangement of accounts that will solve the problem, but separation of accounting may reduce likelihood or delay the inevitability...

- Both in our early 30s, no kids.

- Our salary goes to our individual savings accounts.

- A shared checkings account gets topped up to $5000 every month, proportionally to both of our salaries, to optimize for equal purchasing power when buying shared stuff.

- We don't really budget anything because we save quite a bit, but we do classify all bank transactions into a few categories and look at a month-by-month matrix every few months.

- Both the topping up and generating the analytics are automated processes, so it's pretty headache-free.

> - A shared checkings account gets topped up to $5000 every month, proportionally to both of our salaries, to optimize for equal purchasing power when buying shared stuff.

I'm assuming this isn't automated, right? Asking because if your bank does somehow allow an automatic transfer based on a target amount in an account that'd be really cool.

Ally let's me do recurring transfers to support the same account setup that they mentioned.
Yep, it's automated, but not through the bank. I had to go through the PSD2 and register myself as a payment service provider for my personal account so that they don't charge me.

It's a tedious process but now I don't have to care about this anymore. Although probably the total time required was higher than any time I'll save in the future.

Mostly separate finances: individual checking accounts, individual savings accounts, individual credit cards...and one shared savings account. I'm the only one with a paycheck but my wife gets paid a set amount into her checking account every other week. Bonuses get split between us 3 ways usually...between each savings account we have. I take care of all bills except her credit cards.
I will add that I'm in my 3rd marriage and have learned the best way to reduce fights and stress about finances it to keep it mostly separate.
Whatever you decide, its important that the spouse is really, actually OK with it and understands it. Its nice to have one partner take care of "money stuff" but it's also nice to know you are able to do things independently of them if you need to. This is why most of our finances are shared, but we each have a separate account that we keep relatively well-funded that the other has no access to. I don't think either of us uses these except to check the balance, but if either of us suddenly needed to, say, buy airline tickets to get out of town in a hurry, we wouldn't need the permission of the other. We obviously also have our own 401ks.

I think this peace of mind keeps decisions about joint assets less contentious.

We have our own separate accounts with one joint checking account. We transfer money into the joint account for any shared expense.
Same here, and pretty much the same as I've always done with partners.

One account for me, one account for them, and one shared account from which "shared" bills come from - be it rent or mortgage, electricity, food, etc.

Sometimes a person will say "I drove you to the countryside will you give me money?" or I'll say "I bought us tickets for a gig, you wanna pay me back, or you wanna buy me beer all night?" So sometimes there is some play back and forth about expenses/costs, but typically we transfer just enough to the shared account to cover the expected outgoings each month.

We use this approach. 14 years in and have a mortgage as a shared expense (auto withdrawal from our personal accounts covers this). This has worked just fine for us.

Bigger purchases (car, new heating system) we discuss individually based on our savings and income at the time.

Joint checking, joint investments, joint credit cards. A couple inherited accounts that we kept in their individual name. We don't worry about it.
Same here. Everything joint except for a credit card on both sides that are individual but are really old accounts so they help our credit scores.
Congratulations!

Finances are a common source of strife in marriages. Getting and staying on the same page is critical. Communicate about finances openly and often. Budget together. Review the budget together regularly. It sounds like you are already starting this. That is a good sign. Never stop.

As far as your specific question: I'd recommend joint for day to day and emergency fund. While its simpler, the main reason is mental: its not my money and your money, its our money. We do keep investments separate, but its still "ours".

That is just a recommendation though. Its more important that you both talk about and agree on your approach.

Thank you!

I appreciate the advice. I am a firm believer in structuring things to encourage the desired mental load.

Whatever you decide, get it in writng and signed by both of them. This is the only way to avoid future arguments which, as you surely know, will happen in the happiest of families.
When I got married we ended up merging her acct (same brick and mortar bank) into mine and adding her on the acct along with opening a savings account . Nowadays we also have accounts with online banks that have high yield savings and part of our checks go into both banks. The online bank savings accounts has different “silos” that can be setup for various purposes soI transfer money into each of these monthly. My wife and I don’t do individual wants/splurges silos but this is a great place to save individually while still getting high interest.
We have a hybrid approach--we each have our own bank accounts and credit cards, but also a joint savings account and a joint checking account that covers regular household expenses. My wife is pretty good at doing the budgeting thing and makes monthly-averaged estimates of the regular bills. We have a joint credit card for shopping for stuff like groceries and other household supplies. We've been doing it this way for 20+ years and everything gets paid for and we rarely argue about money.
You don't want to know what we do.

You want to know what is going to work for you.

What conversations have you had with your future spouse about finances? What do you value (e.g. what is worth parting with you money for)? How do make decisions about day to day spending, big expenses, savings rate, long-term planning, investing, retirement?

Are you on the same page on all of those things? Do you disagree on how much to save and invest?

Is "simplicity" the only thing you really prioritize?

All money is our money, and our number one financial priority is our child. We are both on the same page on this.
Our finances are quite simple at this point. We both work but my income is higher than hers. We each maintain our own accounts and credit cards and generally pay for our own personal purchases. For shared things, we either split them proportionately or 50/50 and one of us pays the bill and the other uses Cash App to reimburse for their portion. (We're also new at this, having been married less than a year and our strategy may change in the future.)
We started like this as well, and almost 20 years later we still haven't gotten around to doing anything different.
Sharing accounts is like sharing a toothbrush, that's my philosophy ;)
We have a joint checking account. I automatically draw our investments to our joint Fidelity account.

I try to keep a balance of $50k in our checking account (it's a minimum that our bank sets to give us perks and a free safety deposit box). At the end of the month, if we over that, my partner knows that we can splurge on dining, vacations, or other stuff. If we are under that, we tighten our spending for a bit until we are back over it.

I tried all sorts of budgeting and tracking ideas, but most just weren't worth the effort.

I imagine you have gotten this advice before, but IMO a high yield savings probably makes sense. Say keep 10k in checking for bills, and then the other 40k in high yield. It will more than easily pay for the safe deposit box!

For myself we have joint everything, and then purchases over a certain threshold we need each others permission.

How can you know if a HYSA makes sense if you don't know what the perks are for OP's bank beyond a safety deposit box? Premium checking accounts are niche products, but their perks can add up for the right person. OP might be getting a big discount on their mortgage interest and double the credit car points by maintaining that balance, which could greatly overshadow the (taxable) interest paid on a HYSA.
Let's say it's a whooping 2%

That's a full $1,000 a year of taxable income.

Anything less than five figures isn't worth a few hours of hassle.

$50k liquid is better than 3 days to clear bank money.

High yields are 5% now -- I get who cares about 2k now, personally I wish I did the high yield earlier. I did somewhat similar to OP for maybe 10 years and lost out on low 5 figures when I go back and calculate interest lost.

I am familiar with the perks for BoA and they are not worth losing out on high yield interest at this range. If the reason is for safe deposit though (as the OP said) it is very much not worth it. (I can't find on google Fidelity perks easily, mortgage is the only one that could plausibly make sense, but I am skeptical of that.)

So my high yield is liquid, I can do large purchases on credit card and pay it off with high yield. It did only take a few hours to create the account for what it is worth, so again IMO worth it over parking a large sum of money in a checking.

Two young professionals, no kids.

We each have our own bank account(s) and credit cards and our own budget in YNAB. I manage both budgets but only do hers when she’s present.

We agreed on what constitutes a shared expense ahead of time (mortgage, utilities, etc) and split them based on what percentage of last month’s household income (post-tax) each of us earned. This is variable since we both do some contracting/consulting outside of our day jobs.

For going out, vacations, shared groceries, etc., we just split things as we go. We have a joint savings account that we put the same amount of money in each month and use for travel etc.

A friend and his girlfriend have a joint credit card that they put all shared expenses on and split at the end of each month, but managing that in YNAB is not the smoothest so we haven’t done that yet. Might write some software to make it easier.

> Two young professionals, no kids

There’s an acronym for that.

DINK’s == Double Income No Kids

Net contributors to the economy.

Get a pre-nup, they're cheap. I didn't set up any joint accounts with my spouse so I kept most of my money when we divorced.

I used combinations of checks, cash, and PayPal to give them money when they needed it. Eventually I admitted I didn't want a partner who never had any income of their own.

If you can really help it, don't marry anyone.

Do you often find that your close relationships end when you decide the benefits aren't enough to justify continuing?

I don't know how to say this without it sounding critical, have you ever considered thst you might be suffering from narcissistic personality disorder?

I have considered that. I asked my therapist a few times and she says I'm not a narcissist. I'm not sure what the criteria are. I do experience sympathy (or empathy, which ever is the one where I can feel bad for someone without feeling literal pain), and guilt, and compersion and such, but at times I think I'm more Machiavellian than average. I don't want a relationship where I give and give and realize I've accidentally given more than I can emotionally afford. So I'm purposely under-giving for a while.

Close relationships are very hard for me. I can count on one finger the number of close friendships I've had that were not romantic relationships. I can count on two fingers the number of romantic relationships I've had. I'm 35 so I'm not old but not young. It's probably a combo of gifted-kid BS and autism and general being an engineer, plus having a sudden glow-up a few years ago and feeling unlovable and ugly before that.

Maybe it was just the wording, but your gp post makes it sound like you didn't have any affection for your wife. What was her reaction? I wouldn't call this Machiavellian because Mach. was advising princes to act in opposition to their nature as a necessity for survival in the all out warfare of Italian city states. You however make it seem like you decided to have a layoff to get your household financial metrics in line, despite having no real motivation to do so.
I have affection for them. And some of it's my fault for agreeing to things that I hoped I could do, like co-habiting, instead of things that I knew I liked, like living separately.

The motivation is that I'm no longer yelled at by the person I love the most, who I'm supporting financially and emotionally. They were right about some things, my depression got to them, I probably should have left sooner, I probably should not have escalated as far as I did, and I am just kinda having a mid-life crisis and trying to make up for my 20s being boring.

Do you think I did it all for no reason? Do you think people regularly get married despite having no love at all, then divorce for no reason? Maybe it's fair to say I only had a crush, not real love. We should teach kids the difference. Nobody told me.

> Do you think I did it all for no reason?

This is what I was wondering, and why I suggested there might be some kind of emotional disorder involved. From your most recent post you sound completely normal, the marriage wasn't working out and you felt like it was hostile. This sounds like a pretty typical failed marriage.

From your original post, you simply said "Eventually I admitted I didn't want a partner who never had any income of their own." as the only motivation for why you divorced, and in your initial response you didn't seem to be surprised by my interpretation at all.

Thank you for tolerating my curiosity!

It's not super simple, but here's how we did it for a long time:

All of your income that's not invested for retirement goes to a joint account, every 1st of the month. From that joint account, you then move the money to many different accounts and/or prepaid credit cards: - Day to day expenses, like groceries. - "Irregularities": municipal taxes, school taxes, things that don't happen every month, like car inspection, veterinary, vacation expenses. You add everything in a spreadsheet that you keep, and divide by 12. Add some padding. - Home improvements, aka "IKEA" account. Fixed amount every month. If it's a good that you buy to add you our home (coffee machine, chair, curtain, etc.), that's the account. If it's a consumable (gas for the car), use "day to day expenses". - Individual accounts: each one of you have an account that you decide what to do with. Buying clothes, hobby, etc. aka "I'm an adult, I do what I want". - Kids: There's always something to buy. Clothes, etc. - Automatic payments are taken from the main joint account, but you could also have another account if it makes it easier.

This method can get confusing and you may need to move money from one account to another one when the wrong card was used. But the main advantage is that it automatically budgets for you. You see the amount remaining for the month for everything. Otherwise, you may think that you still have plenty of money to spend on the grocery, so you buy a nice coffee machine, and then the mortgage and car payments happen and you're left with nothing for the rest of the month to do the grocery.

The main goals we had when using this method were to never use a credit card (and lose track of how much money we have), and also accommodate for the discrepancy in our revenues at the time.

Salaries go to a joint savings account.

Bills / savings/ investments / daily living expenses come from that (via credit card or checking account).

We also pay each other some pocket money to spend on our own hobbies and other stuff.

We put money into a shared account for joint expenses, and she and I keep separate finances for ourselves, like whatever else is left over. I also try to put extra into the joint so we can have a joint savings, for emergencies and what not. My wife has her own personal savings as well, that she's always had.

I recommend just opening a shared account and putting a bit above the bare minimum into it. Keep some "you" cash so you can always buy yourself stuff, and you know, if you're ever buying surprise presents, she doesn't need to know. ;) Other people just join it all, and call it a day.

I only join whatever is a dual-expense, otherwise, its either on her, or on me solely.
