subtotal

Synonym discussion
Sense: noun/1
All four terms refer to a figure calculated before the final addition is complete. 'Subtotal' is the standard term in retail and accounting — it appears on receipts and invoices as the total before tax and discounts. 'Partial sum' is more technical and common in mathematics and programming, where it refers to the sum of a subset of elements in a sequence. 'Running total' emphasises the dynamic nature of a cumulative figure that updates as each new item is added, whereas a subtotal is typically a fixed intermediate value. 'Interim total' is the most formal of the group and is often used in budgeting and project cost tracking to indicate that the calculation is paused but not finished. In everyday contexts, 'subtotal' is the most appropriate choice for a learner.

Etymology
The word combines the Latin prefix 'sub-' (meaning 'under' or 'below') with 'total' (from Latin 'totus', meaning 'whole'). The result is a number that sits beneath the larger, final total in a calculation — an intermediate sum that is part of a larger whole.
