How to handle couple finances 

at any stage of a relationship.

Love and money don’t always mix. And when they don't, they can cause nail-biting stress in a relationship. As our generation redefines what relationships even are, we’ve built an interactive guide to helping you and your significant other figure out how to handle and combine your finances. Whether you’re just moving in together, recently got engaged, or are juggling three kids and a marriage, there’s something for everyone in here.

Love conquers all things except poverty and toothache.

Meet Maya and Mike, a recently engaged couple who live in Birmingham, Alabama. They’re trying to figure out how to manage their finances moving forward.


Age: 28

Job: School teacher

Income: $45,000

Money personality: Spender

Financial history: $56,000 in student debt

Preferences: Wants to maintain some


Age: 29

Job: Graphic designer

Income: $75,000

Money personality: Saver

Financial history: $6,000 in CC debt; $5,000 in Crypto

Preferences: Hates how his parents kept 

                    separate finances

Discuss these questions before selecting a merge model.

Deciding how to manage your finances will be one of the first and most important decisions about your financial future as a couple. Doing this thoughtfully and with open consideration for your other half is crucial. It's worth noting that the way in which you merge your finances may evolve over time. For example, some couples might choose one approach earlier in their relationship and grow into another one as their lives become more intertwined. How you handle your finances when living together might look different than how you manage finances in a marriage. Whatever you select, there is no "one size fits all" approach here – finding the right model will require an open-mind and honest conversation with your partner.

GOAL: get a sense of your individual money personalities. Are you a spender who enjoys vacations and eating out? Or are you saver who’d rather contribute to your retirement account than buy a new car?

Some questions to ask yourselves below. If you’re up for it, you can even play our full 20 questions game here.

Things to consider

  • What did you learn from the way your parents approached their finances? Did you like or dislike something about their approach?
  • Is there anything in either of your histories that might make you uncomfortable with money?
  • How do you currently handle your finances? What’s working well? What’s not working well?
  • Do you have similar or very different money personalities?
  • What does financial independence mean to you? How important is it to you?
  • How do the assets or debt that each of you have coming into this relationship change how much you want to combine your finances?
  • What has your expectation been regarding whether you’d want to merge your money or keep it separate from your partner?
  • If you chose “Model X,” how would that change if you moved in together/got married/had a baby?
  • In the event that you separate, how would you want to handle your finances?
  • Do you expect to get any inheritance from your family? How would you want to use that money?

Model 1: All in it together.

Combining your finances isn't always straight-forward for a couple, as each partner can have different perspectives on how they'd like to do it. Here’s the good news, though: there are multiple models that a couple can use, allowing you to select the one that is right for you. Below, we cover three core models for merging your finances. While we've included recommendations for different stages of relationships, you should use the model that works for your relationship!

Models for combining finances

In this model, couples bring all of their assets and liabilities together. This means only having joint bank accounts that are held in both partners’ names. 

Married couples, and especially for couples with kids. This is not recommended if you’re dating or engaged, because it’s often too soon to merge your finances fully. In the event of a breakup, your money would not be protected.

Works well for: 

  • PRO: It's easy to setup and manage over time. Budgeting is a lot easier when you're treating your expenses and income as one. 
  • PRO: Some couples have reported feeling closer together as a result of having combined finances — it offers full transparency into where your money is going and what your significant other is spending on. 
  • CONS: It can create for a messy situation in the case of a separation or divorce. Unless you’re comfortable just splitting your assets down the middle, it can be difficult to determine who contributed what many years down the line – which can then become a big source of contention in a divorce proceeding. (Read more on pre-nup agreements below).
  • CONS: It requires you to be 100% on the same page about how you want to manage your finances, which can be hard to achieve. Sometimes one partner’s passions may not match those of the other partner, which can become a source of ongoing tension in the relationship. 

Pros & cons: 

How to implement this model: 

  • Start by selecting which account/bank you prefer. You can use an existing bank account that one of your has, or start fresh. For more on how to set up a joint bank account, we recommend speaking with your preferred bank. The good news is that in most cases, it takes less than 10 minutes to create a joint bank account online. 
  • We'd also recommend having a checking and a savings account where both your names are on the account. 
  • *Pro Tip* Even if you’re merging everything, get a credit card in your own names (not the same as a joint credit card). This allows you to build individual credit history so that in the case of a divorce or your spouse's death, you’re not credit-less at a time when you might need it most.




According to TD Ameritrade’s 2017 Love & Money Survey

of happy couples discuss finances at least once a month

Model 2: Yours, mine, ours.

In this model, couples merge part of their finances in a joint bank account and put the rest in an individual account (sometimes called an allowance). This allows them to easily handle their shared expenses but still have financial independence for the purchases they want to make individually.

Couples who are living together, engaged, or married. This is also our number one tip for couples moving in together: along with planning for your move, you should consider setting up an “ours” bucket for your finances.

Works well for: 

  • PRO: If a partner really values their financial autonomy, this model allows them to maintain that independence while easily managing and paying for shared expenses. 
  • PRO: Partners report feeling less scrutiny over their own purchases since they're coming out of their individual accounts. For example, you have the ability to support other family members or buy large items out of your individual account without feeling like you’re spending your shared money. 
  • PRO: It’s easier to pinpoint where your money is going (personal vs. shared spending) and what it’s going towards (eating out together vs. eating out by myself).
  • CONS: If you’re married, some relationship experts believe that having separated finances creates an unproductive distinction between "mine" and "yours." 
  • CONS: Separate accounts can create trust issues with your partner — especially if one partner likes to be in the know or is prone to suspicion.
  • CONS: Some critics feel like certain pre-marital money (like student debt or mortgages) should be a shared burden, as you’re both benefiting from the fruits of those investments during your marriage.

Pros & cons: 

How to implement this model: 

  • If you make very different incomes, you can choose to contribute to your joint bank account equally or proportionally to your income. Check out our varied income section for more details on how to approach this.
  • Establish a few key shared accounts:
         Joint checking account - where you each contribute your portion of income.
         Joint savings account - pull any excess money into this account for your goals.
         Joint credit card - gives you each the ability to charge shared purchases easily.
  • *Pro tip* Make sure both your names are on your shared accounts and credit card. That way either of you can access your accounts in case of an emergency. It’s worth noting that this also means either of you can remove money or charge things to your credit card.
  • Once you've decided how much each of you is contributing, automate your finances! Set up a monthly recurring transfer after you get paid to fund your joint checking and savings accounts.
  • Hold a monthly money date. Whether over a cup or coffee or a glass of wine, sit down with your partner to look at your monthly expenses and make adjustments to your monthly contributions as needed.


Farnoosh is a believer in the yours, mine, our approach - one she practices with her husband, Tim.

She's also the breadwinner in their family, which incidentally propelled her into a career in personal finance. After realizing that higher-earning women faced a greater risk of burnout, infidelity and divorce, Farnoosh dove head-first into figuring out how best to handle this dynamic in a relationship.

Based on her research with 1,300+ women, Farnoosh published her findings in her book: When She Makes More. You can learn more about Farnoosh and her hugely successful podcast, So Money.

  • Estimate your shared expenses (rent, eating-out, travel) and set a target shared monthly budget. This will give you a sense of how much you need to cover together.
  • *Pro tip* Looking at your spending habits over the past few months can help you get a better estimate of how much you spend together monthly. You can always look at your spending patterns in Zeta by searching categories.
  • Then decide how much you each want to contribute to your shared expenses. Some couples choose to contribute a percentage of their income (eg. 80% of take home pay) while others may select a dollar amount (eg. $2,000/month).

Model 3: Keeping it separate.

In this model, couples keep their money and accounts completely separate. Usually, they’ll take ownership over various household bills (eg. internet) or responsibilities (eg. childcare) so they can divide expenses between each other without having to merge accounts.

Couples who are dating or living together.

Works well for: 

  • PRO: Your finances are your own to manage and it doesn't require coordination with your partner.
  • CON: This model usually only works for so long. As your lives as a couple become more intertwined, it's inevitable that your finances will, too. However, there are certainly successful stories of couples who have kept things apart even after having kids!

Pros & cons: 

How to implement this model: 

  • Keep your finances in your individual accounts.
  • Make a list of shared bills/responsibilities and divy them up between yourselves. You can either choose to trade-off paying for these bills or choose to split everything down the middle.
  • *Pro Tip* You can use Zeta to get a rough sense of how much you spend on each of these bills when divvying things up, and then track how much you’re spending on shared expenses moving forward.
  • If you’re choosing to split all your bills, the split expenses feature on Zeta helps you keep a running tally on how much you owe each other.
  • If you’re married or getting married, get a pre/post nup! A pre/post nup will help you keep your assets and liabilities legally separate in the way you initially intended. Not doing so would mean you’d be exposing your money and debts to each other even if they’re in individual accounts.

1. Start an open conversation.

Often, couples don't earn the same amount of money, with one partner earning significantly more or less. In this instance, there’s often a question about how these partners should manage their finances. Whether you're the one earning more or less, there is often some discomfort about what or how you might want to spend the money. If you have entirely merged finances, the lower earning partner could feel guilty about spending money they didn't earn, while the bigger earner could become resentful of contributing more. Whatever the situation, this is a delicate scenario that requires couples to get on the same page sooner rather than later — and communication is key.

Varied or single income couples

It’s important to discuss the imbalance up front - here are a few things to cover:

  • Plan for how much you’ll spend on shared expenses together (here’s a free tool to help you build a budget together).
  • Decide the percentage that each of you is contributing towards those shared expenses.
  • Be clear on any stipulations you might have about how to handle that money (e.g. just for rent and groceries, or for anything we’ve ever wanted).

2. Select from one of three approaches.

Merge everything together.

Some couples with greatly varied incomes still choose to merge their incomes completely. This approach especially makes sense if one partner is staying home to take care of the kids, is in school, or otherwise isn’t earning an income.

Split shared expenses 50/50. 

In this approach, couples contribute equally to a shared pool of money and pay for all expenses through this. It’s often easier to do this via a shared checking account, but it can also be done by trading off bills. This works well for two-income couples, but it has limitations when it comes to major expenses (like buying a home or going on a vacation). Some couples solve that problem by offering to do a proportional split for larger purchases but splitting their fixed expenses down the middle.

Split shared expenses proportionally to income. 

Couples with this split each contribute a % of their income towards shared expenses. If Partner 1 earns $50,000 and Partner 2 earns $100,000, this means that P1 will pay for 33% of their shared expenses and P2 will pay for 66% of their shared expenses. This approach works well if the higher earning partner wants to spend more without making the other feel like they’re living beyond their means.

3. Automate your system.

Once you know how you’ll be doing things, it’s time to make it run like clockwork. Our happiest couples have set up their accounts to directly transfer money into their shared accounts when they’re paid. And they use Zeta to make sure they’re on track towards their monthly budget. This way, the system works without them having to lift a finger. For any unforeseen expenses, couples can make one-time transfers into their shared accounts to offset the larger expenses, or start with a cushion in their shared account for any overages that might occur.


In their case, Maya makes $30,000 less than Mike each year. But because she wants to maintain some independence and he is wary of keeping things totally apart, they’ve chosen to split their expenses proportionally. They’ve also agreed that they’ll revisit this arrangement when they decide to have kids, recognizing that one of them might choose to stay at home and be the primary caretaker.

To calculate their respective portions, we’ve outlined the details below.

Mike and Maya have determined that their shared budget is $3,500/month, including: rent, food, and pet care. They’ve even budgeted for savings for long-term goals like buying a home and paying for their wedding.

Mike’s Percentage:               63% (75,000/120,000)

Maya’s Percentage:              37% (45,000/120,000)



Mike’s Annual Salary:           $75,000

Maya’s Annual Salary:          $45,000

Combined Salary:               $120,000





Mike’s Monthly Contribution:           $2,205

Maya's Monthly Contribution:          $1,295

Total Monthly Contribution:             $3,500

Based on the approach they’ve chosen, Mike will pay for 63% of their shared expenses and Maya will pay for 37%. This frees Maya up to spend extra dollars on her gym membership, or for Mike to save in an independent account so he can have some more cushion.

1. Understand your expenses.

Some couples choose the single-income life - a setup where they live on one of their incomes, funneling the second income directly towards savings (or debt payback). This is a pretty effective strategy if you can pull it off, helping you build strong financial habits early in your relationship. Some couples have even managed to maintain their single-income after having kids (ie. even when their expenses went ☝️dramatically). Doing so has put them ahead for retirement and their goals.

A single income life has to start with first understanding your expenses. Knowing how much you're trying to spend gives you a sense of whether you can even pursue a single-income strategy.  If you find that you can pull it off, decide which of your incomes you'll keep for your expenses and which one you'll direct towards savings/debt. 

2. Make your second income invisible.

Once you know which income you're living on, make the second income totally invisible. If you're using it to pay down debt, have it automatically go towards that payment. If possible, don't deposit your second income into your checking account; instead send it directly towards a saving account. The goal here is to make yourselves forget that you've got this second income - you can't miss something you never had!

3. Check-in regularly.

It's good to circle up on your primary income weekly or monthly (we’re fans of having a regular money date - here’s how) and on your second income every 3-4 months. If you're using it to pay down debt, check to see if that still makes sense. If you're trying to invest it all, review the funds or the stocks you've invested it in.

How should we plan for a single-income life?

There are a few things to be aware of when you're married, especially from a legal perspective. Below is a quick rundown on how the law treats your assets and debt.

Marriage law 101

How does the law see our money?

If you're married, the legal view of your assets depends on your state of residency - whether you live in a common law or community property state. Most states are common law property states; however, some states (such as California, Texas, and Washington) will treat the income you generate as a married couple as combined and owned equally (aka community property). This means that even if you choose to separate your finances, you and your significant other will have a claim to any earned assets/debts in the event of a divorce. You can learn more about marital law and finances here

All other states typically follow "equitable distribution" which means that a judge will decide what is fair rather than splitting your assets down the middle. Usually, that split will assign a larger percentage to the higher earning spouse and a lower one to the lower earning spouse. You can find more information about equitable distribution here

There may be exceptions to the laws outlined above if you've signed a pre or post nuptial
(see below).


Common law

A term used to determine the ownership of marital property (property acquired during marriage). In states that follow the common law system, property acquired by one member of a married couple is owned completely and solely by that person.

Community property

Community property states follow the rule that all assets acquired during the marriage are considered "community property,” meaning all assets and liabilities are owned equally (50/50). This marital property includes earnings, all property bought with those earnings, and all debts accrued during the marriage. Community property begins at the marriage and ends when the couple physically separates with the intention of not continuing the marriage. Community property includes: money either spouse earned during the marriage, things bought with money either spouse earned during the marriage, and separate property that has become so mixed with community property that it can't be identified.


Separate property

Any assets acquired before or after the marriage are considered separate property, and are owned only by that original owner. Separate property includes: property owned by just one spouse before the marriage, property given to just one spouse before or during the marriage, property inherited by just one spouse.

Pre/post nuptial agreement

An agreement made between two people before or after marrying that establishes rights to property and support in the event of divorce or death.

Should we get a pre/post nuptial agreement?

Generally, if you or your partner have a strong opinion on how your assets should be divided in the event of a separation, you should consider a pre or post nuptial agreement. Some couples don’t like these agreements because they feel like they can create an “out-clause” or make it easier to break up. While there are pros and cons to be argued either way (we wrote about them here), at Zeta we believe that the conversations these agreements drive have inherent value in and of themselves.

These are a few situations where pre/post nups can be especially valuable:

  • If one partner is bringing significantly different assets into a relationship
  • If one partner is projected to inherit a large sum of money
  • If one or both partners are the child of divorced parents
  • If one or both partners have a history of infidelity

If you’re interested in learning more, you can see an example prenuptial agreement and learn more here.

Woah, you made it through this comprehensive guide to combining finances — congrats! We hope you leave feeling empowered to have conversations as a couple about the merge model that makes the most sense for you and your financial goals, and that you know how to start making progress on building that system. Good luck!
