# CS-64: Splitting shared flat expenses

Category: Money & financial tools
Level: Beginner
Suggested duration: 2–3 weeks

Original UXCharan practice scenario. Validate assumptions; do not present it as a commissioned client project.

## Problem
In a hypothetical city flat, three to five flatmates pay rent, electricity, Wi-Fi and groceries in different ways and track it in chats and spreadsheets, which leads to awkward reminders and missed payments. Explore a shared-expense experience that keeps everyone clear on who owes what.

## People to learn from
Young working professionals and students sharing a rented flat

## Core scope
- Add a shared bill
- split it fairly
- settle up with a reminder

## Research questions
- How do flatmates track and settle shared costs today?
- What makes asking a friend for money feel uncomfortable?

## Edge cases
- A flatmate moves out mid-month
- one person paid the full bill in cash
- unequal splits for different room sizes

## Specific artefact
A monthly 'who owes whom' summary that simplifies payments to the fewest transfers

## Evaluation question
Can flatmates see their balance in seconds and settle up without a single reminder message?

## Work to share
Problem and role; anonymised evidence; alternatives and rationale; task flow; prototype; accessibility considerations; testing findings; revisions and honest limitations.
