Try this link.
Its all in French, cant find the button to switch it to English…(so inconsiderate of our gaullic neighbours!! 
)
Im sure a couple of others have been posted, wait a while and someone else will post up.
Bullitt.
I just used the website to enter the route I took to Switzerland last week and the tolls were accurate to within a Euro or so.
hitch:
www.viamichelin.fr will calculate tolls as well dunno how accurate
My route came out the same as the other website - so fairly accurate, I guess!
