Plan the gap between writing and posting
A backlog protects your schedule when a chapter takes longer than expected. Enter the chapters that are ready now, how often you plan to post, and how many chapters you normally finish each week.
The run-out date is a planning estimate. Recalculate after a missed week, a batch of new chapters, or a change to your posting schedule.
Compare your posting pace with the catalog
The pace note compares your planned interval with 15,648 catalog records that have a recorded release interval from 1 to 365 days. It gives context, not a rule for how often you must publish.
Web Novel Backlog Calculator FAQ
How does the Web Novel Backlog Calculator work?
It subtracts the chapters you write each week from the chapters you post. It then divides your finished backlog by that weekly difference.
How many chapters should I finish before launch?
Choose a buffer that gives you time to miss a writing week without missing a post. The right number depends on your posting rate and normal writing rate.
What happens if I write as fast as I post?
Your buffer does not shrink. The calculator will show that the schedule can continue while your writing rate stays at or above your posting rate.
