sumtotal

Sumtotal, or sum total, is a term used across mathematics, accounting, and computing to denote the final amount obtained after adding a set of numbers or items. In mathematics, the sum total is the result of a summation—often the sum of a finite sequence or the limit of an infinite series. In accounting and invoicing, the sum total refers to the overall amount due, including items, prices, taxes, and discounts.

In programming and data processing, sumTotal (often written in camelCase) is a common variable name storing the running total of a collection or calculation, and developers may use alternative names such as sum or total. The concept underlies basic aggregation algorithms, and attention to numerical precision can matter when summing large sequences of floating-point numbers; methods like compensated summation can help mitigate rounding errors.

SumTotal Systems is a software company known for cloud-based human capital management (HCM) solutions, including HR, payroll, time and attendance, and talent management. The SumTotal brand has appeared in enterprise software products and has been integrated with various partners and platforms within the broader HR technology ecosystem.

The term sum total is also common in everyday language, appearing in phrases such as “the sum total of the purchases.” As a construct, it can function as a noun or as part of modifiers in technical or financial contexts, illustrating how a simple arithmetic idea underpins both practical calculations and more complex software and business applications.
