Direct answer: The simplest way to split expenses in your first apartment together is to use a shared expense app like Splitt. Log each shared expense as it happens, and both partners see a live balance of who has paid more. Settle up once a month with a single transfer. No spreadsheet, no joint account needed.
Moving in together is exciting. It is also the first time you have to manage shared finances in real time, every week, indefinitely. Before, splitting a dinner or a weekend trip was simple. Now you have rent, electricity, water, internet, groceries, household supplies — and all of it needs to be tracked fairly between two people.
Most couples start with good intentions and no system. One person pays rent, the other does the grocery run. Someone buys kitchen supplies, someone else pays for the broadband setup. By the end of the first month, nobody really knows who has paid more — and that vague feeling creates the first friction.
A clear system from day one avoids all of that. Here is what works.
Before tracking anything, both of you need to agree on which expenses go into the shared pot. Shared typically means: rent, utilities, internet, groceries, household supplies, and meals you eat together. Personal means: your own clothing, individual hobbies, personal subscriptions you use alone. Write it down so there is no ambiguity later.
50/50 is the simplest option. Proportional — each person pays a percentage based on their income — feels fairer when there is a significant salary difference. Either works. The important thing is that you both agree before you start, not after a month of guessing.
The moment one of you pays for something shared — at the supermarket checkout, when paying the electricity bill online — log it in Splitt. Takes five seconds. Both partners see it instantly. Waiting until later means forgetting, and forgetting means disputes.
At the end of each month, open the app and see who is owed what. One person makes a single transfer to the other. Balance resets. No ongoing debt, no accumulated resentment. Clean slate every month.
Free, no install, no bank account. Both partners see the same live balance in real time.

Not logging expenses immediately: "I'll remember later" is the most common mistake. You will not remember the exact amount, and neither will your partner. Log it at the checkout or when paying the bill — takes five seconds and prevents every argument about who paid what.
Assuming you both have the same definition of "shared": One partner thinks groceries means everything in the fridge. The other thinks it means only the joint meal ingredients. Have the conversation explicitly before anything goes into the tracker.
Letting the balance grow too long without settling: The larger the balance gets, the more uncomfortable it becomes to ask for it. Monthly settlement keeps amounts manageable and the dynamic healthy.
Mixing the shared account with personal spending: If one person's salary goes into a shared account and personal expenses come out of it too, the tracking becomes a mess. Keep a clear boundary between what is shared and what is personal.
No. A joint bank account is one way to manage shared finances, but it is not the only way — and for many couples it adds more complexity than it solves, especially at the start.
Opening a joint account requires visiting a bank together, choosing a product, and agreeing on how much each person contributes and when. It also means any financial problems for one partner can affect the other's account.
A shared expense app like Splitt requires none of that. Each of you keeps your own bank account. You log shared expenses as they happen. The app calculates the balance. Once a month, one person transfers money to the other through their existing accounts. Simple, clean, no paperwork.
If you eventually want a joint account — for a mortgage, for joint savings goals, for simplicity when finances are fully merged — that is always an option later. But for a first apartment, an expense tracking app is faster, simpler, and carries no financial risk.
Splitt is built exclusively for two people. There are no groups, no complex settings, no categories to configure. You and your partner each have access to the same shared space:
It works in the browser on any phone — no download, no storage space required. Also available on Google Play for Android if you prefer a native app experience. Free forever, no subscription, no bank connection.
The simplest approach is to use a shared expense app like Splitt. Every time one partner pays for something shared, they log it instantly. The app shows a live balance of who has paid more. Settle up once a month with a single transfer. No spreadsheets, no arguments, no joint account required.
Not necessarily. Many couples prefer to keep separate accounts and use an expense tracking app to manage shared costs. A joint account makes more sense once finances are more integrated — mortgage, children, joint savings goals.
Typically: rent, utilities, internet, groceries, household supplies, and shared subscriptions. Personal expenses — clothing, individual hobbies, personal subscriptions — are usually kept separate. Agree on what counts as shared before you start tracking.
Once a month works well for most couples. It keeps individual transfers manageable and gives both partners a clear picture of the month's shared spending. Some couples settle every two weeks if the balance builds up quickly.
