Rent split calculator
Split rent fairly across roommates — by equal share, room size, or income. See exactly who pays what before signing the lease.
How should you split rent?
The fairest answer depends on what your household values most. Three common methods:
- Equal split — everyone pays the same. Simple, but unfair if rooms vary in size or amenities.
- By room size — bigger room = bigger share. Most equitable when bedrooms differ in square footage or have private bathrooms.
- By income — share scales with each roommate's earnings. Common when one housemate earns substantially more.
Whichever method you pick, write it down at move-in. Kutira handles all three automatically and tracks who's paid each month.
FAQs
Is this calculator free?
Yes. No signup, no email gate, no math. Punch in numbers, see the split.
Should the largest bedroom always pay more?
Usually yes — but factor in bathroom access, closet space, natural light, and whether the room has a balcony. Square footage is a starting point, not the rule.
How do I track recurring rent splits each month?
That's what Kutira is for. Set up a monthly recurring expense once, and it auto-posts on rent day with everyone's share calculated automatically.
