Fair Rent Breakdown
Total: $3000 / moThe 50/50 Balanced Formula
Half of your rent pays for equal access to the kitchen, living room, and amenities. The other half is distributed based on private square footage and exclusive perks.
Private Bathroom Premium
An ensuite master bath is weighted at +15% to +25%, ensuring housemates who share a hallway bath don't subsidize luxury perks.
Couple Fair Share
Couples sharing a master room use twice the hot water and fridge space. Our algorithm accounts for common space footprint.
Got questions?
Is Flatmate free to use?
Yes! All core household features including task tracking, basic expense splitting, and flat invites are completely free.
How does expense splitting work?
Whenever anyone buys items for the flat, log the amount. Flatmate automatically calculates exact net balances so only necessary settlements take place.
What happens when a flatmate goes on vacation?
Activate Vacation/Away Mode for that member. Task assignments automatically bypass them during their travel dates.
Can I use Flatmate on both web and mobile?
Yes — your household stays in sync across web and native apps, so you can log a task or expense from whichever is closest at hand.
What if a flatmate doesn't pay their share?
Balances stay visible to everyone in the flat, and reputation stats make missed settlements hard to ignore — no awkward reminder texts needed.
Split rent is decided. What about chores & utilities?
Flatmate automates chore wheel rotation, tracks recurring Wi-Fi bills, and provides 1-tap debt settlement.
