I am looking for something that will take the sefer I want to learn, and the amount of time/days I want to complete it in and tell me the average amount I need to learn a day. It doesn't have to be precisely that, but something of the sort that will help me decide a pace for learning. Good answers will have information/links to resources as well as a brief descriptions of the resources.
There is an excellent website for such calculations here. It is customizable based on the sefer and review schedule of your preference. It is a little complicated, but provides example entries to help you figure out how to use it. Also, there are links on the side of that webpage leading to versions of the calculator specific to daf yomi/ amud yomi/ tanach/ mishnayos/ rambam/ halacha.
