Expense Split Calculator
Split rent, groceries, travel, utilities, group dinners, or other shared costs between people using equal shares, custom percentages, weighted shares, or income-based splitting. See exactly who owes what and the settlement needed to balance everything.
Burrow Tip: The best split method depends on the type of expense. Equal split works well for many shared costs, but income-based or weighted splitting is often fairer for rent or larger recurring bills.
This tool also tracks who already paid so you can calculate the final settlement instead of just dividing the bill.

How to use these results
Shared expenses get easier when you separate two questions: what each person should owe and what each person already paid.
- Equal split: best for symmetric group costs like dinner, rides, or evenly shared utilities.
- Custom percentages: useful when you already agreed on exact percentages.
- Weighted shares: helpful when one person should count as more or less than another without using exact percentages.
- Income-based split: often more practical for recurring shared living costs like rent.
This tool helps you calculate a clean settlement. It does not decide what is fair for your relationship or group — it only applies the rules you choose.
