How Bill by Days works
We use the bill period and your days at home to share the cost in a fair way for everyone.
Step 1
Bill & roommates
Enter the total bill amount, select the exact dates on the bill, and add all the roommates who share this bill.
Step 2
Mark days you were away
For each roommate, mark the days they were not at home during the period. Normal click selects a range. Shift + click toggles a single day on/off.
Step 3
We compute the fair share
Each day equals 1 total point. That point is split only among the roommates who were at home: if 1 person is home → they get 1 point; if 4 are home → each gets 0.25; if nobody is home → everyone gets an equal share. Your cost = (your points ÷ all points) × bill amount.
