> It is CRAZY expensive and the pricing is not really transparent - in our case we had 20 MB of data, 4 1000RUs collections and multi-master write in Western and Northern Europe. The monthly bill? 300 EUR even though Azure Portal was displaying 1/6 of that cost - apparently for multi-master you multiply by the number of regions + 1 (2+1 = 3) and for geo-redundancy only by the number of regions (2), thus the 6x higher cost. The result of that was that we were paying several times more to manage 20MB of data than for all the remaining data - hundreds of GB.

I get your point and they should definitely fix either the cost calculation, or paste a disclaimer for multi-region pricing. But I want to (sincerely) ask how you could assume that multi region would _not_ cost more than single region.

You are perfectly correct, but I assumed that for 2 regions it would cost twice the amount, not 6 times.
