Roommate Expense Split and Budget Planner

What a good one includes

• A proportional rent-split calculation based on bedroom size, private bathrooms, and premium features like balconies.
• A clear breakdown of how utility bills, such as internet, electricity, and water, are split and who is responsible for paying the primary provider.
• A designated system for purchasing and tracking shared household essentials like toilet paper, cleaning supplies, and trash bags.
• Explicit rules on how to handle one-off or unexpected household expenses, including appliance repairs or shared furniture purchases.
• A payment calendar detailing exact monthly due dates and the preferred digital payment methods for transferring funds.
• A written protocol for handling late payments, including grace periods and how emergency financial situations will be addressed.

Common mistakes to avoid

• Splitting rent exactly in half when one roommate has a significantly larger bedroom, walk-in closet, or private bathroom.
• Failing to define how variable utility bills will be handled during peak seasons, such as high air conditioning use in the summer.
• Assuming everyone has the same definition of shared supplies without explicitly listing which items are communal versus personal.
• Relying on verbal agreements instead of documenting the payment rules in a shared, easily accessible digital document.
