- Actuals
- Real expenditures or revenues recorded after they occur, compared against budgeted figures to calculate variance.
- Capital Expenditure (CapEx)
- Spending on long-term assets such as equipment, property, or software that is capitalized on the balance sheet rather than expensed immediately.
- Operating Expenditure (OpEx)
