Rent Split Calculator

Fairly split rent among roommates by room size or income.

Overview

Splits apartment rent, utility bills, and shared groceries fairly among roommates based on room square footage, private bathrooms, and amenities.

Formula & Calculation Method

Roommate Share = Base Common Share + Private Room Premium Adjustment

Splits shared common space (living room, kitchen) equally, while adjusting private room rent by square footage and amenities (balcony, attached bath).

Worked Example: 2-Bedroom Flat (₹30,000 Rent) with Master Bedroom (180 sq.ft) and Small Bedroom (120 sq.ft)

Inputs: Total Rent = ₹30,000 | Master Bedroom = 180 sq.ft (attached bath) | Second Bedroom = 120 sq.ft

  • Common area rent (50% of total) = ₹15,000 split equally = ₹7,500 each
  • Private room rent (50% of total) = ₹15,000 split by area ratio (180:120 = 60%:40%)
  • Master Bedroom private share = 60% of ₹15,000 = ₹9,000; Total = ₹7,500 + ₹9,000 = ₹16,500
  • Second Bedroom private share = 40% of ₹15,000 = ₹6,000; Total = ₹7,500 + ₹6,000 = ₹13,500

Summary: Master Bedroom = ₹16,500/mo | Small Bedroom = ₹13,500/mo | Fair Split Achieved

Common Use Cases

Frequently Asked Questions

How should a couple sharing a room with single roommates split rent?

Split common areas equally per person (e.g. 1/3 each in a 2-room flat with a couple and 1 single), and split private bedrooms by room value.

How much extra should an attached private bathroom add to rent?

Typically adds 10% to 20% to that bedroom's private rent allocation.

How should shared household utilities be split?

Electricity, water, gas, and WiFi should be split equally per individual resident, not per bedroom.
