Do you mean profit rather than interest?

profit=(Selling Price-Buying Price)/Buying Price

so formula would be:

=(B1-A1)/A1 where A1 is Buying Price, B1 is selling price

with your data:

($18-$15)/$15 = $3/$15 = 20% (format cell as %)

One more question...

How to calculate interest in % (difference between two prices)?

// Example
I paid certain article $15 and I'm selling it for $18.
