About the blog:
The goal of this blog is to evaluate different ways of spending your time and money. For example, is it better to change car oil yourself or have someone else do it? The overall idea is to look at spending decisions as to investments: what decisions will return the most value to you over time?
Each scenario is evaluated over a 10-year horizon with the following summary statistics:
- Present value – what is the total value of your investment and expected returns in today’s dollars?
- Return on investment (ROI) – how much of your original investment will you make back?
- Payback period – how long will it take you to recoup your original investment?
The running results of all scenarios are posted to the ROI Scoreboard.
