How should you format your Financial Model?

All the models that I build follow a standardised approach to formatting that is commonly accepted in financial modelling and finance circles.

I know there are others (Green for formula linked to other tabs, etc.) but for me they are overkill and clutter the model, visually. So I generally just use these three;

Inputs - blue font in yellow background

Outputs - black font in white background

Actuals - blue font in white background
