Tool Guide
RoomSplit is a free online rent and utility expense divider built specifically for bachelors, roommates, and flatmates who share a house or apartment. Splitting monthly rent, electricity bills, Wi-Fi, groceries, and other shared expenses fairly can quickly turn into a source of friction — especially when flatmates move in and out mid-month, or when some expenses need to be split equally while others should be divided based on actual days stayed. RoomSplit removes the guesswork and awkward conversations by instantly calculating exactly how much each person owes, based on the rules you choose.
This tool is ideal for students sharing a rented flat, working professionals in shared PGs or apartments, and any group of flatmates who want a transparent, fair, and dispute-free way to settle monthly expenses. Everything is calculated instantly in your browser — no app download, no sign-up, and no spreadsheet formulas to manage.
Money is one of the most common sources of tension between flatmates — not because anyone is trying to cheat anyone else, but because manual calculations, especially when someone moves in or out partway through the month, are genuinely confusing. A small arithmetic mistake or a rounding disagreement can snowball into weeks of awkwardness. RoomSplit removes that uncertainty entirely by doing the math consistently every single month, so the numbers speak for themselves and everyone can trust the outcome.

It's meant to make splitting shared expenses transparent and convenient — for any disagreements about what should be counted as a shared expense, we recommend flatmates agree on the ground rules together before entering figures.
