*tl;dr:* How do you measure the use of your time for a monetary--value and cost--perspective?

I'm reading a book called

Brilliant Time Management and in Chapter 2--Understand how you use time--the author proposes different ways to value time based on whether one is employed, self-employed, or on leisure time, which we'll consider to be early retirement. He divides the calculation into two components: cost and value. I've provided two examples below.

**Assumptions for Employed**Value: No clear definition given (for those who bill customers, such as lawyers, that rate is used)

Cost: Benchmarked at approximately 1.5x your base salary.

Hourly rate based on the number of hours worked.

**Assumptions for Self-Employed**Value: Income generated in a year

Cost: Expenses from running the business

Hourly rate based on number of hours worked
