Return percentage

I have a question regarding the returns gain as a percentage of the overall cost of specific shares.

For instance, this is my current investment in AMD:

And this the shares I own:


Where Total gain/loss = (Current share price - Purchase price) * Number of shares and % Gain = ((Current share price - Purchase price) / Purchase price) * 100.

Even converting these prices to EUR I’m unable to have the same values as the ones shown in the application. Am I missing something here? Can someone please explain this to check if I’m doing these calculations in the wrong way?


You need to convert each purchase individually to Euros at the conversion rate you paid at the time.


Ahh yes, that was it, thanks @Donald_Duck.
