Where the percentages come from

The beat sheet is Blake Snyder's, from his screenwriting book Save the Cat! (2005). Snyder pinned each beat to a page of a 110-page screenplay; novelists have long since converted those pages to percentages so the structure scales to any length. The anchors are the ones storytellers quote from memory: opening image at 1%, theme stated at 5%, catalyst at 10%, break into two at 20%, midpoint at 50%, all is lost at 75%, break into three at 80%, finale from 80 to 99%, final image at 100%.

For an 80,000-word novel that means the catalyst should detonate around word 8,000, the story turns into act two near word 16,000, everything falls apart around word 60,000 and the finale occupies roughly the last 16,000 words. Treat the positions as guide rails. If your all-is-lost moment lands at 72% no beat-sheet police will call, but if it lands at 40% you probably have a structure problem worth a look.

Prefer something looser? The three-act table splits the same manuscript 25/50/25: a quarter to set up the world, half to complicate it and a quarter to resolve it. Both structures describe the same underlying shape; Save the Cat just names more of the joints.
