Moving in together merges your finances whether you plan for it or not. Couples who skip the money conversation often hit friction in the first few months because nobody agreed on who pays for what. This checklist covers the six decisions that matter most.
Why money talks matter before you sign a lease
Shared rent, shared bills and shared groceries all create small money decisions every week. Agreeing on the rules first turns those into routine. If talking about money feels hard, start with our guide to talking to your partner about money without fighting.
1. Decide how you will split rent
If your incomes are similar, 50/50 usually works. If there is a meaningful gap, splitting in proportion to income is often fairer. Agree on the method on purpose rather than defaulting to 50/50 out of habit. See how to split rent fairly as a couple and the income-based formula.
2. List every shared recurring bill
Rent is only the start. Write down every shared recurring cost:
- Rent or mortgage
- Electricity, water and gas
- Internet and streaming
- Renters or home insurance
- Groceries and household supplies
- Parking or transit
For each one, decide: split in proportion to income, split 50/50, or the person who uses it most pays. Writing it down prevents monthly renegotiation. Our couple grocery budget guide covers the food line.
3. Choose your account setup
There are three common setups:
- Separate accounts with tracked bill payments.
- Yours, mine and ours: individual accounts plus a joint account for shared bills.
- Fully joint accounts.
Many first-time cohabiting couples start with "yours, mine and ours" because it keeps some independence while making shared bills easy.
4. Plan for one-time move-in costs
Budget for the upfront costs: a security deposit (often one to two months' rent), first and last month's rent where required, moving costs, and furniture or household items. Aim to keep at least one month of combined rent and utilities saved on top of these costs as a buffer. For furniture, read how to split furniture costs with a partner.
5. Talk about existing debt
Debts do not merge when you move in together, but each person's payments affect how much they can put toward shared costs. Large student loan or credit card payments are the main example. Discuss it upfront so the split reflects reality.
6. Set up a system before day one
Couples who avoid money friction usually have an agreed way to log shared expenses and see the running balance from the first grocery run. Mutual (Shared expenses for couples) is our app. It covers shared expense tracking, income-based or equal splitting, savings goals, monthly budgeting, bill reminders and reports. It is free to download on the App Store for iPhone and does not need a bank login.

FAQ
How should couples split rent when moving in together?
Many suggest splitting in proportion to income when there is a meaningful income gap, and 50/50 when incomes are similar.
Should we open a joint bank account?
Not necessarily. Many couples keep separate accounts and use an app to track shared expenses, or add a joint account just for shared bills.
What should we discuss before moving in?
Rent or mortgage, utilities, internet, groceries, insurance, furniture and moving costs, and how each person's debt is handled.
How much should we save before moving in?
Aim for at least one month of combined rent and utilities as a buffer, plus enough for a security deposit and moving costs.
