FAQ

Common questions

How do I split an internet bill?

Add the plan price, equipment fees, taxes, and recurring fees, then divide by the number of people or use an agreed percentage.

Should equipment rental be split?

If the equipment is used for the shared connection, many roommates include it in the split. Agree on this before billing starts.

What if one roommate moves out mid-month?

Prorate by days in the billing period or use whatever rule the household agreed to in advance.
