I'll quote for a 'frozen ATPL' ie. CPL/IR with all ATPL subjects passed, all done in the UK, from scratch on minumum hours (ie. rare).
Prices range from £35,000 - AUD 92,000 - EUR 54,000 (modular do-it-yourself route) to £60,000 - AUD 157,000 - EUR 92,000(full-time, integrated route)
It can be done cheaper than this on the modular route, but that requires time outside Europe - SA/Oz/NZ/US being the favourites.
