What does this tool do?
Shared bills are easiest to divide by the number of people or rooms paying. This calculator shows each share, the daily cost and the annual total for one share.
The Formula
Share = Total bill ÷ People (or Rooms); Daily share = Share ÷ 30.44Frequently Asked Questions
Should utilities be split by people or by room?
By people is simplest when usage is similar. By room suits households where rooms differ a lot in size or private bathrooms are involved.
What about unequal usage?
A single bill rarely shows who used what. For large differences, agree on a weighted split or install submeters before the next billing cycle.
