How much do you make?
Chances are, you think of your annual earnings. That's not the ideal comparison.
Suppose that Callie earns $100,000 a year and Sandy earns $50,000. We'd conclude that Callie earns twice as much because we ignore an important factor: the hours worked. Suppose Callie works 80 hours a week while Sandy works 40. Then both earn the same hourly rate. Now who's ahead? Probably Sandy who has more time to enjoy life.
The idea of looking at earnings on an hourly basis came from The Four Hour Work-Week by Timothy Ferriss. The book is one of my favourites. It got me thinking about wisdom acquired years ago: the cost of anything is how much of your life you pay (e.g., money, time, health). Too often we think only of the cost in dollars.
Tax
Since our tax system is "progressive", the more we earn, the higher our tax rates. In our example, Sandy likely comes out ahead when we look at after-tax earnings per hour.
If you're paid a salary or commission, you probably don't know what you earn per hour. You may be shocked once you do a quick calculation.
I am indeed rich, since my income is superior to my expenses, and my expense is equal to my wishes. --- Edward Gibbon
Nothing hurts more than having to pay an income tax, unless it is not having to pay an income tax. --- Thomas Robert Dewar
