Free publishing tip: is there a benchmark number for copies sold to make the book considered a success?

A reader asks:

Is there any kind of benchmark for how many copies of memoirs sold make the book considered a success?

Memoirs are bought (by a publisher) and sold as novels are. One thousand copies sold would be considered really good for a first-time, unknown or little-known author. Five thousand copies would be considered excellent.

I am a first-time, unknown novelist from a relatively small press. Notably, mine is a first-person account of surviving incest, which is about as hard to sell as anything. I’ve sold about a thousand copies in the first year and a half.

My goal for this book, however, was not to make a mint. I am too aware of the reality of selling books. My goal was, firstly, to have my novel published by someone other than myself. (Our industry does not look kindly on self-published writers of literary fiction.)

Secondly, I treated this debut novel as a bit of a loss-leader. My second but equally important goal was to garner good reviews and prizes so as to set myself up to find a better deal with my second novel than I did with the first, and to find it more quickly.
