Yes, you can call yourself a financial advisor... IF you are doing more than a features/benefits/price presentation. If you're looking at someone's retirement, college, taxes (now and in retirement), debt load, etc., then you're a financial advisor.
Note that "financial advisor" is NOT a regulated term (in most states). Investment advisor, insurance agent, registered representative are all regulated terms. There are a couple of states where they have ruled that to call yourself a financial advisor/consultant/planner requires a Series 65 - so make sure you check on that.
