Guides

Each guide explains one decision the calculator asks you to make, with worked examples.

• Reading the billing period on a utility bill

  Which dates to enter, and which amount belongs to this period.

• Daily split and person-days: two agreements, two answers

  Worked examples of both methods and what changes when a room is empty.

• Fixed charges, empty days and rounding

  Standing charges, who shares them, unassigned days and leftover cents.

• Sharing the result and keeping a backup

  CSV, print or save as PDF, JSON backups and deleting your entries.
