Formula to Calculate Dividend Yield with Franking

Hi 

I would like a formula to calculate the dividend Yield for my shares plus Franking as a percentage. 

EG Share price is 1.14. Dividend is .0375.  

On the calculator I do the following

Dividend plus 43% divide by the share Price equals the percentage.

.0375 + 43% / 1.14 = .047039473%.
