How long will it take to finish your TBR pile?
I frequently tell people that I’m going to live forever because you can’t die with unread books. I’ll never get through all the books on my TBR list, so I assume I’ll never die.
Then I found the To Be Read Calculator: http://www.readitforward.com/tbr-time/
Enter how many books you have in your TBR pile, how many books you read last year (so it can calculate how fast you read), and your age. It will tell you how many years of reading you have—assuming you don’t buy more books!—and how old you’ll be when you finish. Of course, you could do this simple calculation yourself, but this is more dramatic.
