Student Roommate Expense Split Calculator — How It Works

Splits a shared expense evenly between roommates, with an optional per-night breakdown.

How it works

  1. Enter the total cost of the shared expense (rent, utilities, a group trip, etc.).
  2. Enter the number of people splitting the cost.
  3. Optionally enter the number of nights or days, to also see a per-night breakdown.
  4. The tool divides the total cost evenly among everyone.

Formula

Each person pays = Total cost ÷ Number of people
Per night = Each person's share ÷ Number of nights

Example

A $600 shared cost split between 3 people is $200 each. Over 3 nights, that’s about $66.67 per person per night.

Why this matters

Splitting shared costs evenly and transparently — whether for rent, a shared grocery run, or a group vacation — avoids awkward conversations about who owes what.
