Numbers accept a dot or comma decimal separator, without grouping. Monetary amounts are labelled in USD; no currency conversion is performed. These are estimates rounded to two decimals, except itemized budgets and expense splits, which use exact cents.

How to use this tool

Enter the total expense in whole cents and each party's agreed share, area or weighting. Leave the optional third share blank for two parties. Remaining cents go to the largest fractional shares, with ties awarded in source order, so the allocations add exactly to the expense.
