Summing Up the Mix Connected Load

I want to calculate the connected load of my workshop where;

1. Three phase motor 1.5Kw 01
2. Three phase motor 05Kw 01
3. Single phase motor 1.5Kw 01
4. Light fixture single phase 250W 09
5. Fan single phase 100W 06

I am confused that how to calculate the net connected load because the power of three phase motors can be sum up but what about single phase lighting and other load? Do I just sum up the power of all loads? For example, in this case, the net connected load is 1.5 + 5 + 1.5 + 2.25 + 0.6 = 10.85Kw. Am I right or wrong? Sorry for my lack of basic knowledge.
