Every figure comes from what you typed; there is no recommended discount on this page. The break-even does not predict who comes for a discount: it tells you how many would have to, for the discount to cost you nothing.

A discount the invoice shows, for the families you choose
In Pillar OS a discount is a coupon code you create: a percentage or a dollar amount, an end date, once or on every payment of a plan, sent to the families you pick. The invoice shows the lessons at full price and the discount under them.

Questions owners ask before they try it
What sibling discount should I give?
This page does not say. It shows what each discount costs you in a month and how many children it has to bring in to cost you nothing; slide the discount to compare.
How would I know a child came because of the discount?
You cannot know for sure. You can ask when a family enrols a second child, or when a student adds a lesson, whether the discount made the difference. The calculator shows how many would have to say yes.
Is a pack discount the same thing?
No. A pack discount is paid back by a family staying longer, not by a new child. The tutoring package calculator on this site shows how many extra sessions pay a pack discount back.
