We're using SQL Server 2012 and have page compression turned on for a number of our larger tables. Is there a way we can determine the compression ratio we're getting? We'd like to be able to determine the benefits of compression.

Can you afford creating non-compressed copies of compressed tables? By doing that, you can easily find the uncompressed size. Sure, it's unelegant but could work.– vonPryzOct 14 '13 at 12:54

How about sp_estimate_data_compression_savings?
It allows you to estimate the gain from compression BEFORE you compress the table, but it's quite accurate.

Yeah, I saw that but that is just an estimate. I wanted the actual compression ratio, if it's available. And, besides, we've already enabled compression on many of our tables. Sep 20 '13 at 14:43

2@Randy: You can use that stored procedure to do what you want: use the parameter
@data_compression = 'NONE'. Oct 14 '13 at 19:10
