RentSplit

RentSplit is a free browser-based set of rent calculators for roommates and shared homes. It gives people several transparent ways to explore a monthly rent split, including equal-by-room, room-size, equal-by-person, custom percentages, custom monthly amounts, income-based splits, prorated rent, and rent concessions. Each method keeps the key assumptions visible so roommates can see which inputs affect the result and compare alternatives without hiding the calculation behind a black box. Users can enter the total rent, describe the rooms or household inputs, review the resulting amounts, and copy or print a neutral explanation for a practical household discussion. The tool can help with a new lease, a move into a shared home, a room change, or a temporary concession while leaving the final choice to the people involved. RentSplit is not legal, financial, or tenancy advice and does not determine what a lease or local rule requires.

What problem it solves

Roommates need a clear way to compare rent splits when rooms, space, income, or temporary concessions differ.
