There is actually a formula to determine the size a service should be, but
given the parameters you've already described, your existing 100 amp should
be fine

The main panel is only 100 amps, and I was mistaken - there are
actually 7 available slots, not 5 as I had stated before. Would you
still recommend upgrading to 200 amp service if I added the fact that
this is a townhouse - it is only 2 bedrooms and 1800 sqft. Thanks,
