We pay a royalty of 90% minus 50 cents per paid purchase.
Royalties are paid at the beginning of each month via PayPal. To receive payment, you will need to set up a PayPal account, which is free. When you create a Leanpub account, if you don't set a special PayPal email address, we automatically try to send the payment via PayPal to the email address you use for your Leanpub account. Once you've created a book on Leanpub, you can set or change the email address we should send PayPal payments to here:
Because of our 'Happiness Guarantee', which allows readers to claim a refund for 45 days after their purchase, there is also a 45-day 'hold period' applied to the royalties associated with any sale. Once the royalties related to a purchase are past the 45-day 'hold period', then those royalties will be paid out at the beginning of the next month. So, for a purchase made on September 1, the 45-day hold period will expire on October 15, and the royalties for that purchase will be paid on November 1.
Finally, please note that if your book is purchased for free, then there will not be a 50 cent fee for the free purchase. Free purchases are free for authors too.
