Frequently Asked Questions
Common questions about the free online expense split calculator.
Enter the bill amount, the tip percentage and the number of people, then press Split the bill
to see what each person owes.
Yes. Choose uneven shares by weight and type a weight for each person, such as 2 for a couple
and 1 for a single guest.
Each person receives their own weight divided by the total of all weights, so a weight of 2
pays twice as much as a weight of 1.
The tip is added to the bill before sharing, so every share already includes its part of the
tip.
Enter the bill, set the tip, switch to uneven shares and give the larger eater or drinker a
higher weight.
The calculator falls back to equal shares so the bill is still divided without any division
by zero.
Up to fifty people can be entered, and the table lists every person with their own weight and
amount owed.
Amounts are shown to two decimal places. If the total is a fraction of a cent, adjust one
share by a cent.
