The formula
Sales needed equals your revenue goal divided by your price per sale, rounded up to a whole sale. If you enter a close rate, conversations needed equals sales needed divided by that rate, also rounded up.
5K Challenge calculator
Published by Book Profits Club. Last updated: November 2026.
Divide $5,000 by your price per client and round up: at $1,000 per client you need five. This calculator from Book Profits Club does that math for any goal and any price, and can estimate how many sales conversations you need from your close rate. Use it to set a realistic target before you start the 5K Challenge for authors.
Enter your goal and price, then select Calculate to see how many sales it takes.

It assumes one price, no refunds, no payment fees, and no taxes. It is an estimate, not a prediction of what you will earn. Book Profits Club does not publish average member earnings.
