Split the rent

Last updated 29 September 2026

Rent, electricity, Wi-Fi, the maid, the gas cylinder. The same bills every month, and the same message to chase them. Here’s a calmer way to share a flat’s money.

Set up the flat

Start a group for the flat and add your flatmates. Everyone adds their own UPI ID, so whoever pays the landlord can be paid back in a tap.

Bills that repeat

Set up the rent, the maid and the Wi-Fi once: how much, who pays, how it’s split, and how often. A bill can repeat every week, fortnight, month, quarter or year.

When one is due, Mull doesn’t just add it. It asks, with the amount ready to change, because rent goes up, the electricity is never the same twice, and people move out. Whatever you confirm becomes the new normal, so next month asks for the new number.

If nobody opens Mull for a while, it doesn’t pile up the months you missed. It asks for the one that’s due.

When it isn’t equal

The bigger room pays more? Split the rent by percent or by shares. Someone away for a month? Each month’s rent is its own expense, so change that month’s split and leave the rest alone.

A worked example

Ananya, Kabir and Sahil share a flat. Ananya has the bigger room, so she pays 40% of the rent.

BillPaid byEach month
Rent, ₹24,000AnanyaAnanya ₹9,600, Kabir ₹7,200, Sahil ₹7,200
Wi-Fi, ₹900Kabir₹300 each
Maid, ₹3,000Sahil₹1,000 each

Once the month’s bills are confirmed, each flatmate sees one number with each of the others:

WhoOwesWhy
KabirAnanya ₹6,900His ₹7,200 of rent, less her ₹300 of the Wi-Fi
SahilAnanya ₹6,200His ₹7,200 of rent, less her ₹1,000 of the maid
KabirSahil ₹700His ₹1,000 of the maid, less Sahil’s ₹300 of the Wi-Fi

When someone moves out

Settle up with them first. Then change the repeating bills to the flatmates who are staying. The bills they already shared stay in the flat’s history, because those were real.

Questions

Who should pay the landlord?

Whoever usually does. Add the rent as paid by them, and everyone else owes them their share.

The electricity bill is different every month.

Set it up as repeating anyway. When it’s due, put in this month’s amount before you confirm it.

Do all my flatmates need Mull?

They should. With everyone on Mull, they add what they paid, confirm what you sent and get your reminders themselves. If someone won’t install it yet, you can still split with them by name.
