Net Price Calculator - Institutional Gift Aid & Scholarships

Does anyone happen to know how the Institutional Gift Aid that’s listed when the Net Price Calculator is run works?

Because it populates when we run the NPC, does that basically mean it’s almost a guarantee that that amount would be offered, assuming everything is input correctly?

How does scholarship money play into this? Is scholarship money assumed into that Gift Aid? Or is scholarship money used to cover the remaining cost of attendance?
