What is a roommate expense splitter?

A roommate expense splitter is a tool that tracks shared household costs — rent, utilities, groceries, internet, streaming — and calculates exactly who owes whom. Instead of keeping receipts and doing mental math at the end of the month, every roommate's balance is updated live as expenses are added.

This shared expense calculator works entirely in your browser. There is no signup, no app download and no account. Your data is saved locally on your device, so your household budget stays private.

Split rent, utilities and every shared bill fairly

Not every expense should be split the same way. Rent might be divided by room size, groceries evenly, and a pizza night only between the people who joined. This calculator supports four split methods:

Equal split — divide the amount evenly between all roommates
Selected roommates only — split between the people who shared the expense
Percentage split — for example 40 / 30 / 30 based on room size or income
Custom amounts — enter an exact amount per person

Fewest possible payments

The settlement algorithm compares what each roommate paid with what they should have paid, then simplifies the debts. Instead of everyone sending money back and forth, the calculator reduces the settlement to the minimum number of transfers — a simple online alternative to apps like Splitwise, without the login.
