Frequently Asked Questions

▾
Q

What's the difference between FV and compound interest?

A

Same concept. FV = future value calculation. Compound interest = the mechanism (interest on interest).

Q

How does compounding frequency matter?

A

Annual: once/year. Quarterly: 4x/year. Daily: 365x/year. More frequent = slightly higher FV.

Q

Is $100 today worth the same as $100 in 10 years?

A

No. Time value of money: $100 today > $100 later due to earning potential and inflation.
