# Calculate product set totals

> Computes line and set totals for unsaved form items the way a saved set's `items_total_price` is
computed (`unit_price × quantity`, plus tax at `tax_rate`), in the clinic's base currency. Line
figures are rounded for display; `total` is summed from the unrounded lines and rounded once.
Nothing is saved.
