Let Homies keep score for you
Should roommates share groceries or buy separately?
For most households, the honest answer is: share the staples, separate the rest. The two pure models exist, but each fits a narrow case. Full sharing — one list, one budget, everyone eats everything — works when you genuinely cook and eat together most nights, and collapses the first time a vegetarian funds someone else's steak habit. Full separation — four shelves, four oils, your eggs and my eggs — suits ships-in-the-night schedules, and quietly costs everyone money in duplicates while the fridge fills with four of everything.
The hybrid keeps what each model does well: a communal pool for things the apartment consumes as a unit, personal shelves for everything taste-shaped. It's also the model that survives roommate turnover, because it doesn't depend on everyone eating alike.
| Model | Works when | Where it breaks |
|---|---|---|
| Share everything | You cook and eat together most nights | Different diets, appetites, and budgets |
| Buy separately | Schedules barely overlap | Four olive oils, everything duplicated |
| Hybrid: shared staples | Almost every shared flat | Only if nobody restocks the pool |
What should be shared and what stays personal?
The test is simple: if the apartment consumes it as a unit, it's shared; if a person consumes it as a preference, it's personal. Shared: oil, spices, sugar, flour, eggs, onions, garlic, condiments, and every household supply — toilet paper, dish soap, trash bags, sponges. Personal: your oat milk, their protein powder, the snacks with one owner, anything tied to a diet.
Then pick one default for the gray zone and say it out loud: communal unless labeled, or personal unless it's on the shared shelf. Either rule works; the absence of a rule is how the last of someone's milk starts a cold war. Keep the communal items on a shared grocery list that updates in real time, so staples re-add themselves the moment the last roll is opened and the pool never silently runs dry.
How do you split the cost of shared groceries?
Evenly, monthly, through a running balance — not per-receipt transfers. Whoever does a run logs the receipt that day; at the end of the month, one balance settles everything at once. In a four-person flat where the month's communal runs came to ₪430, ₪380, and ₪340 by three different shoppers, that's ₪1,150 total — ₪287.50 each — and the balance simplifies who owes whom into one transfer per person, instead of nine apologetic micro-payments.
Two refinements keep it fair. Rotate who does the run, because schlepping bags is labor even when the money splits evenly. And if your house hates math entirely, use a kitty instead: everyone puts ₪300 a month in the pot, the pot pays for staples, and you adjust the number twice a year. Less precise, never surprising — the same trade-off as splitting the utility bills, just in smaller numbers.
What about different diets and the roommate who eats more?
Appetite differences are almost always smaller than they feel, and metering them costs more in trust than it recovers in shekels — nobody wants to live in a house that counts eggs. The even split survives because staples are cheap and consumption roughly averages out across a month.
Genuine category differences are the exception, and they're handled by moving items between pools, not by weighing portions. A vegan housemate shouldn't fund the house's meat: meat becomes personal. Someone with a costly specific diet keeps it on their own shelf. And the roommate who's away half the month can take a reduced share for that month — agreed once, as a standing rule, so each trip isn't a renegotiation. Crude-but-agreed beats precise-but-fought-over, here as everywhere.
How do you keep grocery money from becoming scorekeeping?
The friction never comes from the splitting; it comes from the remembering. The shopper who fronts ₪430 and waits three weeks to mention it isn't tracking groceries, they're accruing resentment. The fix is mechanical: log the receipt before the bags are unpacked, let it split across the house automatically, and settle everything on one fixed day a month through the house's running expense balance.
This is exactly the seam Homies, the app for running a shared home, was built to close: the shared grocery list and the who-owes-who balance are the same app, so checking off the run and logging the receipt is one motion — a ₪430 shop becomes four clean ₪107.50 lines the moment it's paid, and the staples pool restocks itself from standing items.

Frequently asked questions
Is it cheaper for roommates to share groceries?
For staples, almost always. Four people buying four separate olive oils, four bags of rice, and four dish soaps are paying for storage, not eating — sharing the pantry basics cuts the duplicates and unlocks bigger package sizes. The savings disappear if you force-share preference items, because then people double-buy privately anyway. Share the boring things; keep the personal things personal.
How should roommates split groceries with different diets?
Move the diet-specific items out of the shared pool instead of doing per-item math. The communal pot covers what everyone genuinely uses — oil, eggs, onions, cleaning supplies — and anything tied to one person's diet lives on their shelf at their cost. The vegetarian never funds the steak, and nobody audits anyone's snacks.
Should the roommate who cooks for everyone pay less?
Keep money and labor in separate ledgers. The cook's ingredients for a house dinner are a shared expense, logged like any other — but their time is chore-economy, traded against dishes or shopping runs, not against shekels. Mixing the two ("I cooked, so I owe less") gets murky fast; parallel fairness stays clean.
What's the easiest way to track who paid for groceries?
Log each receipt the day of the run and let a running balance do the rest. Homies pairs the shared grocery list with automatic receipt splitting, so the shopper gets paid back without asking and the month closes in one transfer per person.
