Tips for Splitting Fairly
Keep one shared list
Use a shared Apple Reminders or Google Keep list so whoever shops knows what's needed.
Split by meal plan
If you cook together 3x/week, split all groceries. If you mostly eat separately, split only staples.
Photograph receipts
A quick photo archives the split if anyone asks later.
Don't sweat small stuff
$3 of milk doesn't need negotiation — split it. Detailed accounting for <$5 items creates friction.
Split everything vs. split only staples — which works?
Split only staples (eggs, milk, bread, cleaning supplies) is cleaner when roommates have different diets or eating schedules. Split everything works when you cook together regularly. Start with staples-only, then expand if it feels natural.
Frequently Asked Questions
How do you split groceries between 2 roommates?
Decide which items are shared (typically staples + cleaning supplies). Each shopping trip, log the shared portion in Spllito. Settle monthly — usually one Venmo covers it.
Should I split all groceries with roommates?
Only if you cook together regularly. Otherwise split just shared essentials (eggs, milk, butter, spices, cleaning supplies) and keep branded snacks/diet items personal.
What groceries should roommates split?
Shared: staples (eggs, milk, bread, butter), cleaning supplies, paper towels, condiments, spices. Personal: branded snacks, specialty diet items, alcohol, prepared meals.
How often should we settle grocery costs?
Monthly is ideal. Weekly creates too much friction; quarterly lets balances grow awkwardly. Pick the 1st or 15th and stick to it.
Is it fair to split groceries 50/50 if one roommate eats more?
Not quite — if one person clearly eats more of the shared food, a 60/40 split is fairer. Or, keep the big eater's personal food out of the shared pool.
Can I split groceries using Spllito without an account?
Yes — Spllito never asks for an account. Open it, add roommate names, log trips, settle monthly. All data stays in your browser.
How do I split a Costco run with roommates?
Separate the receipt into shared items (bulk staples) and personal items (your favorite brand). Log the shared total in Spllito; pay for personal items yourself.
