# Incremental
Naming pattern: Measures with “Incremental” behavior follow the name
pattern:*Main Measure Name* Incremental.
The Incremental measures evaluate the impact of a trade or a group of
trades ('current scope') on the result at a selected
reference level,
by comparing it with a computation as if the considered trade or
aggregate of trades were hypothetically removed.
$M^{incremental}(\text{scope})=M(\text{portfolio}) - M(\text{portfolio excl scope})$
The impact of query filters on the results can be controlled using [ReferenceLevelVisualTotalsMode](./referencelevelvisualtotalsmode).
Example:
In the following example, the IR K Delta measure is showing the impact of individual NettingSetId on the firm-level IR K Delta number.
* IR K Delta for NettingSetId “ActiveBank EU\_104” is -94, which means that this portfolio is reducing firm-level IR K Delta by 94.
From the screenshot above, we can see that the IR K Delta is 94 greater (594,579 - 594,486) if the “ActiveBank EU\_104” NettingSet positions were closed out.
