Author Income Goal Calculator
How many books to sell for your target income
Making a living from books starts with a real number. This calculator takes your income goal and your royalty per book and shows how many copies you need to sell each month, and each day, to get there, so the goal becomes a plan rather than a wish.
How many books do I need to sell to make a living?
It comes down to royalty per sale. At an average $3 royalty, a $3,000 monthly income needs 1,000 sales a month, about 33 a day. Raise the royalty, add a series with read-through, or add formats like audio, and that number falls. Seeing the target is the first step to planning toward it.
Is a single book enough to earn from?
Rarely on its own. Most authors who earn a steady income do it with a catalogue: several books, ideally in series, so each new reader buys more than one. A single title can succeed, but the reliable path is more books working together, which is why prolific release schedules are common among full-time indies.
What lifts author income fastest?
The biggest levers are more titles, higher read-through within a series, wider distribution across formats and stores, and a mailing list that makes each launch land. Chasing a single viral hit is unpredictable; building a catalogue that compounds is what turns writing into a reliable income.
