The comparison by vouchercloud, a Groupon company, said Romania was found to be the cheapest with the cost per Mbps being £0.09 (A$0.16), followed by Ukraine, Hungary, Israel and Russia.
Asked about the methodology used to get these values, spokesperson Ben Behrens said: "Speedwise, we used data from Speedtest — a user initiated test of local connections — sample size had to be at least 3333 users for the time when the data was taken.
"Its testing infrastructure is made up of over 7000 different servers across 190 countries, so the idea is that you get a good idea of speeds the typical user is actually using, rather than what companies are advertising.
"Packages measured were fixed line, broadband only (or broadband and phone). Broadband and TV package speeds were not included."
The UK was 44th on the list with the cost per Mbps being $1.02 while the US stood at 34th at £0.88.
