The Math of Financial Planning (EP.239)

The concept of financial math is another foundational element of investing and good economic decision-making, and today we are carrying on the recent string of shows dealing with these kinds of fundamental aspects. First, we have a look at the central idea of the time value of money, and how this plays into many areas of our finances, such as retirement planning, spending, investing, and so on. From there, the conversation goes on to cover exponential functions, the tradeoffs between saving and spending, and regrets. Today's 60-second episode recap is of the great conversation we had with David Blitzer back on Episode 54, and we also do a quick book review of the potentially life-changing How to Live on 24 Hours a Day. We finish off this punchy episode with some news from the community and some thoughts on the ways in which competition and repetition can improve a skill.
