1. Title-by-title subscription cost growth: Unsub is designed to forecast your costs and fulfillment, not just report them. To do that, we need to be able to take into account changes in subscription pricing over time. That's what this parameter does: it simply describes the percentage price increase expected every year. The default, based on industry averages, is 8%, but you can change this in your scenario's menu, under "Parameters ➞ Costs ➞ Title-by-title subscription cost growth."
