I just ran the numbers assuming I pay US $3000 /year (I forget Hoffman's actual figure) for 33 years (mind you, I think deathtimer.com is too pessimistic there) discounted at 3% /year (the average annual inflation rate since 1913 equals 3.24%). The EPA set the value of a human life at $9.1 million two years ago. Perhaps I'm rigging the numbers by updating this for (actual) inflation and only discounting it by the 1/1500 probability. But I first estimated the value of my own life at $20 million, and I don't think I'd actually kill myself in return for (say) an SI donation that size.

The 'official' numbers would appear to make cryonics under-priced by $1403 in present value. (Edited to use official figures.)
