I want to calculate the respective variation explained of each effect in my model by means of dividing the sum of squares of that effect by the sum of squares of that model. Is this correct? Or should I divide by the total sum of squares? When adding the sum of squares of each effect, they do not add to the model sum of squares? Why is that?
Do you mean Coefficient of Variation?? OR source of variance??
this for source of variance calculation

Thanks you for your answer. I do need the source of variation but I also need to compare multiple factors. The link is for comparing only one factor to test its significance with the F statistics. Do you have a similar link for multiple factors ANOVA?
you can see this links it might help you
