How to split groceries with roommates
Few things sour a shared flat faster than groceries: one person buys all the staples, another eats them, and nobody's quite sure who owes what by the end of the month.
A little structure keeps the fridge — and the friendship — intact.

Ways to split it fairly
Share staples, keep the rest personal
Communal basics — oil, spices, dish soap, toilet paper, maybe milk and bread — are worth sharing. Personal groceries and special diets stay separate.
Take turns shopping
Rotate who does the big shop and reimburse them, rather than everyone buying duplicates.
Track receipts, not memory
Snap the shared receipt each time. Reconstructing a month of grocery runs from memory is how disputes start.
Split staples evenly, itemize big buys
For genuinely shared basics, an even split beats itemizing every onion. Save itemizing for large one-off purchases.
Frequently asked questions
Should roommates split all groceries?
Usually not. Most households share only communal staples and cleaning supplies and keep personal food separate — it's fairer and avoids policing who ate what.
How do you split groceries when people eat differently?
Keep personal and special-diet items separate, and only split the genuinely shared staples. If diets differ a lot, share less and itemize more.
What's the easiest way to track a shared grocery bill?
Have whoever pays log the shared receipt to a household group, then settle the net total once a month instead of squaring up after every shop.
