Deriving the Perpetuity and Annuity Valuation Formulas 

Really good! I always think it's better to know WHY a formula works than to just know that it works, thanks for the break down!

This is the best explanation of annuity and perpetuity video I have come across so far. Normally, I would not bother commenting on any video. But he is too good to miss out.

Thank you so much for this video! Perfect easy explanation of a seemingly complex concept.

This is what I was looking for but exceeded my expectation. A very clear explanation! Thanks for the contribution.
