Lifestyle ToolsArea-weighted or even split with shared space
Rent Split Calculator: Area-weighted or even split with shared space. Rent Split Calculator uses standard everyday life formulas to compute accurate results instantly.
| Room | Shareable area | Rent share |
|---|---|---|
| Room 1 | 20 + 10 = 30 m² | ¥1753.25 |
| Room 2 | 15 + 10 = 25 m² | ¥1461.04 |
| Room 3 | 12 + 10 = 22 m² | ¥1285.71 |
Steps
- 1Shareable area of each room = room area + common ÷ rooms
- 2Total shareable area = 47 + 10 × 3 = 87 m²
- 3Rent share = total × own shareable area ÷ total shareable area
- Area-weighted split: each room takes (room area + common ÷ rooms), so bigger rooms pay more while shared space is split equally — a fair baseline for negotiation.
- Real-world adjustments are common: south-facing / balcony / private bath rooms usually add a premium on top of the area-based baseline.
- Set the area of an unrented room to 0 to exclude it from both area and rent sharing.
