Operational Expenditure (OpEx)

Ongoing spending on services and operations, such as monthly cloud bills, expensed in the period incurred.

Definition

OpEx covers day-to-day costs of running a business, such as subscriptions, utilities and cloud consumption. Cloud services are billed as OpEx, so there is no up-front investment and costs scale with usage, though spending must be actively managed to avoid overruns.

Example

Paying a monthly invoice for virtual machines and storage used is OpEx.

Exam tip

OpEx is the expected answer when a scenario highlights paying only for what you use with no upfront commitment.
