Show discount rate in percentages

[Pdaal]

Hello,

Our client want to show the percentages of discount for some products on their site. 

Is this possible, maybe with a extra module or something?

For example:

if a product from 100 euro has 10% discount, is it possible to see an banner on this product with  Discount 10%
