What is a subtotal?

A subtotal is the sum of a portion of a total amount or list of items. It is calculated by adding up the values of specific items, products, or services within a larger collection of items. Subtotals are often used in financial statements, invoices, receipts, and shopping carts to provide a breakdown of costs before any additional fees or taxes are applied. Subtotals help to organize and categorize information, making it easier for individuals and businesses to track expenses and make informed decisions.
