Tally.

Split a trip, a dinner, a flat. Every rupee accounted for, down to the last paisa.

Your split (come back to it later)
The result (to share or keep)

    Expenses

    Splits are calculated in whole paise/cents, so the shares always add back up to the exact expense total; the leftover fraction is handed to the people at the top of the list rather than quietly dropped.
