Frequently Asked Questions
How should roommates split groceries fairly?
An equal split works when usage is similar, but a weighted split based on actual consumption (like this calculator) is fairer when habits differ significantly.
What if we buy some shared and some personal items?
Separate personal items out of the shared bill first, then split only the truly shared items using this tool.
Can this be used for utility bills too?
Yes, the same weighted-split logic works for utilities, rent add-ons, or any shared household expense.
