Before you move in, talk about the bills

The spreadsheet had no column for resentment

Amaka’s first contribution to the moving-in conversation was a spreadsheet. Rent, electricity, internet, groceries, cleaning. She colour-coded it on a Sunday while Deji watched football beside her. When she turned the laptop around, he smiled at the total and said, “Perfect. Half each.”

She had meant the spreadsheet as the beginning of a discussion. He had heard the end of one.

Deji earned almost twice her salary. The flat was in the neighbourhood he wanted because it cut his commute. She liked it too, which made objecting feel dishonest. She could afford her half if she stopped sending quite so much to her mother, postponed a course and became the sort of person who always said she had already eaten.

“Why should I be punished for earning more?” he asked when she suggested a different split.

“Why should your preferred lifestyle become my compulsory lifestyle?” she replied.

Neither sentence improved the evening. The football continued playing to an audience of two people who were now determined not to look at each other.

Amaka’s side

“I’m not asking him to sponsor me. I’m asking us to admit that the same amount of money does different things to our lives. His half would inconvenience him. Mine would organise my entire month. If we both pay the same, but one person has to ask permission before ordering lunch, what exactly is equal?”

Her friend Nneka thought the answer was obvious: split the bills according to income. Another friend, Sola, disagreed. She had once paid more because she earned more, then found herself paying almost everything because her partner treated every increase in her salary as a household promotion.

“Generosity can become a subscription you never knowingly signed up for,” Sola said. “Put an end date on whatever arrangement you make. Review it. Don’t turn a kind decision into a permanent job description.”

Amaka disliked the warning because it sounded like suspicion. She also saved the message.

Deji’s side

The part Deji had not put in the spreadsheet was his younger brother’s school fees. He was paying them quietly. He had described his family as “fine” because explaining the arrangement felt like inviting somebody to assess whether his brother deserved help.

He worried that sharing his salary would mean defending every expense. He had grown up watching his parents argue over who had contributed more. He wanted a system that could not be weaponised in the middle of a fight. Half each seemed clean. Predictable. Safe.

Amaka heard this and softened, then became irritated for a different reason. They were preparing to share a bathroom, a lease and a life, but each had been protecting the other from the information needed to make any of it work.

“You don’t have to give me your banking password,” she said. “But you can’t ask me to agree to a picture with half of it covered.”

The bill nobody wanted to own

They eventually found a cheaper flat. That solved the largest number and exposed the smaller arguments.

Who would stay home for the plumber? Who noticed when the cooking gas was low? If Deji bought dinner because he worked late, did that count as a contribution while Amaka’s hour of cooking disappeared into the category of things she supposedly enjoyed?

Their second spreadsheet had fewer colours and more questions. They agreed on an amount each could contribute without abandoning existing responsibilities. They kept personal spending separate. They set a date to revisit the arrangement, including the invisible work.

The conversation did not end with either of them winning. It ended with Deji washing the plates while Amaka called her mother. Neither action proved they had solved cohabitation. It did suggest they had stopped treating it as a maths problem with only one respectable answer.

The uncomfortable question remained useful: are you choosing a life you can both participate in, or inviting one person into a life the other has already priced?

Moving in together can make a relationship feel more settled while making money considerably more complicated. Rent is the obvious conversation. The less obvious ones are replacement gas, guests who stay a week, damaged appliances and what happens when one person's income changes.

This is a practical discussion guide, not legal or financial advice. The purpose is to make expectations visible before you create shared obligations.

Put the full household on paper

List rent, deposits, electricity, water, internet, cooking fuel, food, cleaning and transport changes. Separate recurring costs from one-off purchases. Decide which items you already own and which you are actually willing to buy together.

Use current bills and written quotes where possible. An estimate copied from someone else's apartment may be irrelevant to your building or routine. Keep a buffer for ordinary surprises without pretending you can predict every expense.

Choose a split you both understand

Equal contributions and contributions proportionate to income are different arrangements. Neither should be assumed silently. Discuss what each person can afford, how payments will be tracked and when money is due.

Also discuss unpaid work. If one person buys everything, remembers every renewal and chases every repair, the bill split does not describe the whole contribution. Allocate tasks with the same clarity you apply to amounts.

Give guests and privacy a budget

Talk about visitors, overnight stays and family expectations. Someone hosting relatives may increase food costs, utility use and the need for private space. These decisions deserve a conversation before a guest is already at the door.

Agree on personal spending too. Sharing an address does not require sharing every account password or seeking permission for every small purchase. Decide which decisions need consultation because they affect shared obligations.

Discuss an exit while you are getting along

Record who paid for major items, whose name appears on agreements and how you would handle shared possessions if plans changed. Read the actual tenancy terms, and get qualified local advice when you need help understanding obligations.

An exit discussion is not a prediction of failure. It prevents an emotional situation from becoming even harder because nobody remembers who owns the fridge. Keep records accessible to both people without exposing unrelated private financial information.

Return to the arrangement when income, work or family responsibilities change. You are allowed to revise a plan that no longer fits. For the conversational side, read our relationship check-in guide. A shared home becomes easier when the practical work is something both people can see.
