How to split rent for a 2-bedroom-1-living-room or 1-bedroom-1-living-room? What is the fairest principle?

Common flat types and splitting methods

2-bedroom-1-living-room (3 people sharing):

Here are the common splitting plans for a 2-bedroom-1-living-room shared by 3 people: 1、 Plan A: By room size · Rent allocation: Large room at HKD 2,000, Small room at HKD 1,500 × 2 · Drawbacks: Requires measuring area; large room tenant may be dissatisfied 2、 Plan B: Equal split by room · Rent allocation: Each person HKD 2,333 (total HKD 7,000) · Drawbacks: Large room tenant loses out; small room tenant benefits 3、 Plan C: By tier · Rent allocation: Large room HKD 2,500, Small room HKD 1,750 × 2 · Drawbacks: Requires negotiation; may feel unfair

Recommendation: For a 2-bedroom-1-living-room, the fairest method is splitting rent by room area.

Method:

1. Measure the area of both rooms with a tape measure
2. Rent ÷ total room area = monthly cost per square meter
3. Each room’s area × unit price = individual rent

Example: Total rent HKD 7,000, large room 15 sqm, small room 12 sqm

• Unit price: 7,000 ÷ 27 ≈ HKD 260/sqm
• Large room: 260 × 15 = HKD 3,900
• Small room: 260 × 12 = HKD 3,100

1-bedroom-1-living-room (2 people sharing)

For a 1-bedroom-1-living-room shared by 2 people, the splitting items and methods are as follows: 1、 Rent · Usually split equally (each HKD 3,500, total HKD 7,000) 2、 Shared room · 50% each

A 1-bedroom-1-living-room is often a master bedroom plus a small room. If the size difference is significant (15 sqm + 10 sqm), splitting by room size is recommended.

How to split shared expenses (utilities, internet, cleaning)?

Utility splitting methods:

Here are the splitting methods and notes for each shared utility item: 1、 Water bill · Split into three equal parts · Or by usage (requires submeter) 2、 Electricity bill · Split into three equal parts · Air conditioning and water heater are major costs 3、 Gas bill · Split equally · Usually only for cooking, not a large amount 4、 Internet bill · Split equally · Typically HKD 300–400/month

Reality:

• Most roommates split equally (to avoid complex calculations)
• Monthly utilities + internet: HKD 300–400 per person

Cleaning costs:

• Landlord hires a cleaner: Included in rent (no extra payment)
• Self-cleaning: Rotating duty (one person responsible for common areas each week)
  • Recommended to post a duty roster in the living room
  • Each person cleans about once every 10–15 days
• Hiring an external cleaner: HKD 150–300 per session (monthly or weekly)

Recommendation: Hold a meeting at the start of the month to create a shared expense list covering utilities, internet, and cleaning to avoid later disputes.

Common roommate conflicts and solutions

Here are the common roommate conflicts, their causes, and solutions: 1、 Cleaning not done properly · Cause: Different standards · Solution: Create a weekly cleaning checklist, take photos as evidence 2、 Visitors disturbing others · Cause: No prior agreement · Solution: Inform in advance, limit visitor hours 3、 Expense calculation · Cause: Poor record-keeping · Solution: Use a budgeting app or shared spreadsheet 4、 Food being eaten · Cause: No labels in fridge · Solution: Label items, clarify whose food is whose 5、 Noise complaints · Cause: Different schedules · Solution: Agree on quiet hours (usually 10 PM–8 AM) 6、 Electricity bill disputes · Cause: Air conditioning running too long · Solution: Install smart meters to track individual usage
