End the roommate math arguments. FairSplit is a ready-to-use Excel workbook (Google Sheets compatible) that tracks shared expenses and tells you the minimum transfers to settle up. WHAT YOU GET: a people sheet for everyone sharing costs (roommates, couples, travel groups); an expenses log where each entry marks who paid and who shares - supports equal splits, percentage splits and exact amounts; an auto-calculated balance sheet showing each person's net position (owed vs owes); a settlement solver that reduces debts to the fewest possible transfers: A pays B this much, done. No apps to install, no accounts, no data leaving your spreadsheet - unlike split-the-bill services everything stays in one file you own. Works in Microsoft Excel 2016+ and Google Sheets (File - Import). No macros, no plugins. WHO IT IS FOR: roommates splitting rent and utilities, couples managing shared costs, friends on group trips, any small community with a shared treasury. HOW TO USE: 1. Download after purchase. 2. Add the people. 3. Log each shared expense as it happens. 4. Settle up using the suggested transfers whenever you like. Instant delivery, lifetime updates included.
