Why This Matters

Splitting grocery costs is one of the most common friction points for roommates and shared households. The person who always buys the expensive items, the roommate who eats more than their share, the debate over communal vs. personal items — these small disagreements can poison an otherwise great living situation.

This tool removes the guesswork. By categorizing each item as shared or personal, and tracking who paid, everyone can see exactly where they stand. No more mental accounting or passive-aggressive notes on the fridge.

The simplest approach: shop together, split shared items equally, keep personal items separate, and settle up weekly. This tool makes that process take 2 minutes instead of 20.

Frequently Asked Questions

How does the grocery splitter work?
Add household members, then enter each grocery item with its cost. Tag items as "shared" (split equally) or assign to specific people. The calculator shows each person's total and net debts.
Can I handle different split ratios?
Yes! Shared items are split equally by default, but you can assign items to specific subsets of members (e.g., only adults share the wine cost).
Does it track who paid?
Yes! Mark who paid for the grocery trip, and the calculator shows net debts — who owes whom and how much — to simplify settling up.
