forex calculation mode vs cfd calculation mode MT4 platform

 

As I am new on forex trading. can anyone explain what the difference between forex calculation mode vs CFD calculation mode  on MT4 platform
I have a very simple question, like for 1 pound bet(1 mini lot) in spread bet account(UK) I get 100 pound for 100 pip profit(cfd calculation mode), where as on forex calculation mode for 100 pip profit I get 69 pound profit.

How this profit/loss calculated??


Thanks
