How often do Kindle books go free?

New free Kindle books appear constantly — but the pattern behind them is more predictable than it looks.

Why authors go free

Free promotions build reviews, climb category charts, and introduce readers to a series. Many authors schedule free days around a new release, a sale, or a slow month. That is why free lists never run dry.

How long deals last

A typical free promotion runs 1–7 days, occasionally longer. Discounts can last longer, but free deals tend to be short and urgent — exactly why the expiring soon list is worth checking daily.

There is no secret calendar, but there is a rhythm: check the new arrivals, follow the free page, and grab expiring titles first.
