Hypothetically I want to save $500 per month into an investment
portfolio that earns 10% What is the future value after 30 years?

The real issue is...do I compound interest monthly or annually?
Remember, lets call this investment a collection of funds in a
portfolio. So I'm sure the difference in compounding methods would be
pretty significant. Which would be more accurate? I'd be curious to
see an FV function solution and a non-array solution if anyone has the
talents.

Thanks!
