Shared Rent and Utility Cost Splitter

What a good one includes

• A clear breakdown of individual base rent allocations based on room size, private amenities, or agreed-upon percentages.
• An itemized list of recurring utility bills, including electricity, water, gas, internet, and trash disposal.
• Adjustment variables for partial months, guests staying long-term, or roommates who were away for extended periods.
• A final, single-figure summary for each roommate showing exactly who owes what and to whom.
• Built-in payment tracking indicators to show who has paid their share and which bills are fully settled.
• A historical log of past months' calculations to help track seasonal utility trends and budget for future expenses.

Common mistakes to avoid

• Splitting every utility bill exactly down the middle without considering who actually uses or benefits from specific services, like premium streaming channels or parking spots.
• Failing to account for mid-month move-ins or move-outs, which leads to unfair charges for unoccupied days.
• Forgetting to establish a clear deadline for payments, resulting in late fees that cause unnecessary household tension.
• Neglecting to keep a digital paper trail of receipts, leaving the household vulnerable to disputes if a utility company claims a payment was missed.
