What a household of one couple and two sets of siblings spends on groceries

A household of one couple and two sets of siblings sharing a home offers an unusually clear view of what feeding a group actually costs in 2025.

The residents track a weekly shop that covers six adults, combining bulk staples with a smaller top-up run midweek. Meat, dairy and fresh produce dominate the bill, while shared cooking keeps the per-person figure well below what any of them would spend living separately.

The savings come mostly from scale and planning: buying rice, flour and legumes in large quantities, cooking in batches, and rotating who plans meals so that the mental load does not fall on one person.

It is not a formula everyone can copy, but it illustrates a point economists make repeatedly: single-person households pay a substantial premium for food, and shared living remains one of the few reliable ways to cut it.
