Split rent and bills with roommates, without the monthly maths
Rent, electricity, WiFi, the maid, the cook, groceries — ttmm keeps one running tab for the flat and tells everyone what they owe.
1. Decide how rent is split
The two common ways in Indian flats and PGs:
- Equally — simplest, works when rooms are similar.
- By room size or features — the bigger room, attached bathroom or balcony pays more. Use our room-size rent guide or the split calculator to get the numbers.
In ttmm, add rent once as a recurring bill with those shares. It adds itself on the day you choose, every month.
2. Put shared bills on autopilot
Add WiFi, maid, cook, gas cylinder and society maintenance as recurring bills too. Variable bills like electricity can be added when they arrive — see how to split electricity with AC usage.
3. Add day-to-day expenses as they happen
Groceries, Big Basket, Swiggy, the water can — whoever pays adds it in a few seconds. Split it equally, or only between the people it was for.
4. Settle once a month on UPI
ttmm works out the fewest payments needed so everyone is square. Tap Settle up and it opens your UPI app with the amount filled in. Everyone sees it marked as paid.
Bonus: a fair chore wheel
Dishes, trash, cleaning, buying water — set up a chore wheel and ttmm rotates whose turn it is, so nobody keeps score in their head.
Questions
How do roommates split rent fairly?
Either equally, or weighted by room size and features (attached bathroom, balcony, AC). A common method is to split 60–70% of the rent by room area and the rest equally for shared spaces.
How do we split utilities when someone is away?
Add that month’s bill and leave the away flatmate out of that one split, or use shares (for example 2:2:1).
Can my landlord or PG owner be in the group?
You can add anyone. Many groups just add rent as a recurring bill paid by one flatmate.
