Splitting Expenses with Roommates & Friends

Splitting expenses reliably comes down to three habits: log every shared expense when it happens, agree how each one divides, and settle the balance on a schedule. ZenExpenses splits do the math; this page shows the workflow.

How to track shared expenses long-term

1. Log who paid and how much. Whoever fronted the money adds the expense the same day, with a short note like "Costco, shared groceries".

2. Choose how to split it. Equally, by share, or by exact amounts (see below). The split is per expense, so rent and takeout can divide differently.

3. Settle monthly. ZenExpenses nets everything into one number per person, so a single transfer clears the month. Long-term tracking works because nothing carries over as a vague IOU.

Ways to divide bills

Equal split: divide evenly across everyone. Right for groceries, takeout, and shared subscriptions.
By share: assign weights when usage differs, e.g. the roommate with the bigger bedroom carries a larger share of rent, or partners split bills based on income.
By exact amount: specify each person's portion, e.g. one person ordered more at dinner.
Not split: keep a personal item on a shared receipt out of the split entirely.

How to divide household expenses with roommates

Fixed monthly bills (rent, internet, utilities): set the split once and reuse it every month.
Variable shared costs (groceries, household supplies): log each as it happens, split equally.
Trips and one-offs: one person books the rental, another pays for gas; log both and settle once at the end.

Splits live in their own section, separate from your imported bank transactions, so shared costs never distort your personal category totals.

FAQ

Does everyone need an account?

No. One person can track the splits and share the balance; others join only if they want to add expenses themselves.

How do we settle up?

Any way you like: bank transfer, cash, or a payment app. ZenExpenses tells you who owes whom and how much; the payment itself stays in your hands.

What if someone moves out mid-month?

Settle the balance on their last day, then continue with the remaining people. Because each expense is dated, the cut-off is unambiguous.
