How to split utility bills with flatmates fairly
Rent is easy to split; bills are where flatshares argue. Who uses more electricity? What if someone was away for a month? A few simple rules prevent most of it.
Split equally by default
For internet, water and most utilities, equal shares are fair enough and avoid endless debates. Agree on it when someone moves in.
When to use a different split
- Bigger room or private bathroom: a larger share of rent, sometimes of bills too.
- Someone away for weeks: agree in advance whether they still pay the full share.
- Partner who practically lives there: add them as an extra share.
Someone moving out mid-cycle
Split the bill by days: if the bill covers 60 days and they lived there 30, they pay half of their usual share. Settle it before they leave, not when the bill arrives two months later.
Put it on autopilot
In Settlia create a "home" group, add rent and fixed bills as recurring expenses, and set the group's default split (equal, percentages or shares). Each bill is added automatically on its date, balances stay up to date, and debtors get a gentle weekly reminder. Scan variable bills like electricity when they arrive.
