Frequently asked questions
What is a fair way to split rent?
Use adjusted bedroom area when rooms have similar occupancy. Use shared areas by headcount when occupancy differs. Agree on feature adjustments and record your decision.
How are shared areas allocated?
Enter the total shared area. Its rent is total rent times shared area divided by total floor area, split by occupancy; children under 1.2 m count as half. All-by-bedroom allocates the full rent by adjusted bedroom size.
How is rent split when people share a bedroom?
With shared areas by headcount, enter adults and children in each room. More occupants pay more for shared areas. All-by-bedroom ignores occupancy; agree on the split within each room.
What are base rent and feature adjustment?
Base rent is total rent times the room’s share of bedroom area. Feature adjustment is the difference after applying room features. The final total is the room’s monthly rent; all room totals match the full rent.
How much more should the main bedroom cost?
There is no fixed ratio. Enter room sizes and features to get a starting point for discussion.
Can I change feature adjustments?
Yes. Use minus and plus to change a selected feature by one percentage point. Agree on the adjustment together. Orientation only adds a south-facing premium to avoid double counting.
How many rooms can I use?
Use 2–6 rooms. Add a room with the button, or remove one using its delete control.
