Also with an average 18 month life time hit growth will still be exponential as long as the site keeps growing exponentially as it has done since 2002!

So that means if a bill entered 18 months ago will proably never have a hit after that!
So that will cause growth on the hits not to b exponetional like it could be.. is this right?
That's always the average time. If it was exact, all notes from 01/2002 would have been replaced in 07/2003, and all notes from 07/2003 would have been replaced in 01/2005 at one time
but we still find the first notes, and the most 5ers I find in circulation are still the ones from start of 2002, so I guess the average lifetime is much more than 2 years.
I'd say that over here, the lifetime of a €5 is much less than 18 months - so many crisp €5 notes are released into circulation as the €5s go 'limp' very quickly. People seem to think of €5s as 'loose change' and crumple them into their pockets as if they were a coin. As a result, the notes don't stand a chance!
The other banknotes (€10s upwards) are treated with a bit more respect Notes above €50 are uncommon and notes above €100 are really uncommon, so I'd say they'd last a long time here!

So does anybody know if there is some official information about the average bill lifetime available? I browsed the ECB site a bit, but couldn't find anything useful.
I'm putting together a piece of code which would calculate the effective (or average) number of one's notes that are still in circulation, based on the entry times and the average lifetime. Other than the lifetime, It'd be nice to have the standard deviation also

I don't know about "official" information either, but if you look at my site www.eurotracer.net/information and http://www.eurotracer.net/information/notes.php, you find statistics about note production, note replacement (shreddering) and note circulation. From that and some information about the amount of notes in the reserves (to be found on the ECB FAQ site), you might be able to estimate the life expectancy of the notes, maybe ...
Thanks for the info, thomas.
It would probably be possible to extract some numbers from the things you mention. I chose the easy way - I wrote an e-mail to the ECB
I posted the information they sent me here.
