Illustrator: show scaled percentage

Not sure if this is possible, but is there a way to scale something based on size, then determine the percentage that the object was scaled by?

Example:

I have a square 3" x 3" and i constrain proportions, then scale to 12" x 12". Is there a way to have illustrator show me that it was scaled by 400%?

Obviously this is easy to figure out for this example, but when i am increasing something that 3.2353blahblahblah to 72.534677blahblahblah its a bit more difficult and I'm really just trying to save time
