Frequently Asked Questions
Frequently Asked Questions
Why assign a dollar value to personal DIY time?
Assigning a dollar rate makes the opportunity cost visible. Spending 20 hours on a home project means those hours cannot be used for overtime, professional freelance work, exercise, family time, or rest.
What is the implied breakeven hourly rate?
The breakeven rate is the exact dollar value per hour at which the cash savings of doing the work yourself equal the hours you spend doing it. If you earn or value your time above this rate, hiring is the lower economic total cost.
What about the intangible satisfaction of doing it yourself?
