The calculator provides a snap shop of how you currently invest a rare commodity, your time. The results are displayed in the form of a pie chart. The color diagram is what you know intuitively, but may not have thought about as competition for a slice of your 168-hour week.
With six areas competing for a slice of your week, it is difficult to keep all areas in balance. If your commute time is a larger slice of the pie than your leisure time, then you may want to consider ways of reallocating, such as “outsourcing” some of your chores to increase your leisure. You could talk to your boss about spending every Friday or every other Friday at home, instead of the office. Your commute time could then be redistributed to more hours of sleep or more leisure time. The calculator allows you to re-calibrate all of the times towards a more desired life/work balance.
