If you share the materials from a course you already teach, you earn a royalty on the textbooks they help build. This page is what you earn, when you are paid, and what we ask you for.

You earn up to 2% of the net revenue of every textbook your materials helped build.

Net revenue. Students usually pay through a bookstore, a payment processor, or an inclusive access programme, and each takes a cut of between 2% and 30% before the rest reaches us. Net revenue is what reaches us. Your royalty is a share of that, not a share of what the student is charged.

What sets your share. 2% is a ceiling, not a flat rate. The final amount depends on the coverage, relevance and usability of the materials you share.

How many of you there are. Each title is built from the materials of a group of instructors. You earn alongside a group of other instructors.

You earn nothing from the students in your own classes. Their access is left out of what your royalty is worked out on, so assigning a textbook you helped build earns you nothing from your own class.

Instructors are often asked whether they profit from the material they assign. You can say plainly that you do not. Wording you can paste into a syllabus:

“I contributed teaching materials that were used to build this textbook. I receive no royalty from any student in this class.”

If your institution has a conflict-of-interest process, that is usually what it wants to see. We are happy to confirm your arrangement and the student price in writing. Ask us from the help centre.

Royalties are paid twice a year with the rest of your earnings, every September and every February.

Earnings are counted per semester. Summer is included in the spring semester and winter is included in the autumn semester, so there are two statements a year: the spring semester is paid in September, and the autumn semester is paid in February.

A royalty is counted once the money it is based on has reached us, and that money arrives steadily through the semester as students take up access. Because it travels through an intermediary first, some of it lands a few months after a student pays. Payments are made by bank transfer, and we issue a Form 1099 each year.

We build a title in versions. You earn on every version your materials were used to build, for as long as that version is in use. It is not tied to a calendar year and it is not tied to the life of the title.

A later version may not use your materials. When we build a new version we decide again what it is built from, and contributing once does not guarantee we use your materials next time. If we do not use them, you do not earn on that version. Anything already earned is still paid.

And if we do not use them, we genuinely do not use them. We do not keep fragments of your materials and build with them anyway. Either a version was built from what you gave us and you are paid for it, or it was not and you are not.

Only what you already have from teaching the course:

You make nothing new. There is no writing to do, no recording session to sit for, and no review cycle to keep up with.

We evaluate what you send. Before we use anyone's materials, we email them, hold a Zoom call and reach an agreement. If we are not going to use yours, we delete them. They are not kept, and they are not used to build anything.

None of the output is your material. Your recordings and slides tell us what a course in this subject actually covers and in what order. The text, the videos and the questions we publish are generated from that understanding. Your lecture is not republished, your slides are not redistributed, and your questions do not become our questions.

Every title lists its contributing instructors, with your name and where you teach. The page says plainly what that means: you provided the teaching materials the textbook was built from, and you did not write or review the text.

Everything to do with royalties is on the Royalties page in your account:

Your royalties also appear beside your referral fees on the Earnings page, and in your annual earnings and payments summary under Tax documents.

This article describes the contributing-instructor deal. If you signed a creator agreement with us, those terms stand as agreed. Your share, and how it is worked out, are what your contract says, and nothing here changes them.

These terms apply from 14 September 2026. The terms that applied when you contributed are the terms we pay on. We may change how royalties work for future contributions, and any change applies only from the day we publish it.

Blended cannot give personal tax advice. Your annual documents are in your account under Tax documents.
