Add circuits to primary panel or add a secondary box...?

Early in the planning phase for finishing my basement. Looking for some general guidance on the pros & cons from the experts...even if you could just point me in the right direction for where I could find more info it would be appreciated.

Not enough information to even begin to answer your question. How full is your current box? What is the brand and model number of your panel? What loads are you anticipating? What size is the main breaker?

Other point to consider are how many homeruns would need to go to the panel.

200 amp service, 7 open slots in the box but it is pretty crowded with the wiring to support a 10 breaker transfer box. Running out of space on the neutral bus. Basement is 1500 square feet and I will be supporting general lighting and outlets, bar with full size fridge and my workshop where I use typical power tools and an air compressor. I am figuring 6 home runs to support all...don't need a precise recommendation...just looking for general guidance or a rule of thumb for how to decide which way to go...thanks.

You definitely need a sub panel in the basement. Sit down and figure what amount of power you'll need.

general lighting 1-2 circuits
Fridge 1 circuit
outlets 4 circuits
compressor 1 circuit

That's like 8 circuits needed. A 60-100 amp sub panel would not be out of the question.
