When two people are in a committed relationship, the question of moving-in together comes-up at some point. This question actually triggers a series of other questions such as how to share household chores and if all the belongings are going to fit-in in the new place.

However, there are a couple of very important questions that should not be overlooked: how are we going to pay for the bills and are we going to combine finances?

Long before you move-in, you should have had “the money talk”, as a couple. There are crucial details that partners need to know about one another, such as income and debts, as well as goals.

Once you have the basics down, it is time to take your conversation to the next level.

Option 1: partial combination; 1 joint checking-account, 1 joint savings-account

A joint checking-account is used to pay for common expenses like rent, utilities and groceries. More categories can be added, depending on your situation. If you are a one-car household, then car expenses would also be considered as a joint expense.

If you have similar incomes -or close enough-, you can both contribute 50% to the account. If there is a large disparity between your incomes, use the percentage method instead.

Add your respective monthly net incomes. Divide your individual net income by the combined income and multiply by 100. Always use your net income.

For example, if your net combined monthly income is $ 10 000 and one partner earns $ 2 500, their share is 25%.

It is also a good idea to have a 3-month emergency fund for the shared expenses.

Option 2: almost complete combination

With this option, all the money is deposited in a joint-account and a portion is transferred to each partner’s individual accounts.

All the bills are paid from the joint-account, regardless of their nature. The individual accounts work like an allowance.

The most challenging part of this approach is to decide what amount should be transferred to the individual accounts!

Option 3: complete combination

This approach is definitely the most transparent one. When both partners are on the same page financially, it is also the best.

Communication is key. It is best for both partners to sit down and discuss how to consolidate all their accounts, as well as how to manage them on a day-to-day basis. Both need to be actively involved.

As years go by and children come into the picture, the line between “yours, mine and ours” becomes more and more blurry.

Option 4: complete separation

In this scenario, the couple does not combine finances at all and keeps everything separate. I personally find this method counter-productive. Some household expenses are higher than other ones, and it can be tricky to decide who pays for them. It can also be an hindrance to saving goals or paying-off debt.

You may want to revisit why you are not considering combining finances to some extent. Maybe you have done this in a previous relationship and it was a disaster? Maybe you don’t trust your partner? Maybe your partner has an opposite financial style?

Again, communication is key here. Money is a huge stressor for couples and the leading cause of divorces.

Final word

Deciding to combine finances -or not- is a very personal decision. What will work for a couple may not work for another. It is important to find the system that works for both your partner and you. Don’t worry about what outside people think.
