By default, the cost of your Big Deal is $2.2M, increasing at 5% annually. Of course, you'll want to change this to match the actual cost and increase % for your institution. This number is used in your forecast to show how much you'll save, if you cancel your Big Deal.
This number is set at the scenario level, not the publisher level. That lets you try different Big Deal costs in different scenarios.
Here's how to set it for any given scenario:
Open the forecast scenario you are interested in.
Click Parameters➞Costs➞Big Deal Cost
Enter your cost and click Save, then wait for it to recalculate.
Changing the annual Big Deal cost increase works the same way, but click Parameters➞Costs➞Big Deal Growth.
