Pricing things in life-hours
Convert a purchase into the hours of your life it costs to earn, then decide.
Key takeaways
- What it is: Convert a purchase into the hours of your life it costs to earn, then decide.
- Why it works: Money obscures cost because a price feels abstract. Translating a purchase into the working hours required to pay for it (after taxes and job-related expenses) makes the trade explicit: you are exchanging a slice of finite life for the item. That reframing recruits the brain’s sense of opportunity cost, which prices usually hide.
- Evidence: Plausible mechanism, limited direct outcome data.
- Avoid: Using a gross hourly wage that ignores taxes and the costs of working, which understates the true life-hour price and weakens the reframing.
Why it works
Money obscures cost because a price feels abstract. Translating a purchase into the working hours required to pay for it (after taxes and job-related expenses) makes the trade explicit: you are exchanging a slice of finite life for the item. That reframing recruits the brain’s sense of opportunity cost, which prices usually hide.
How to do it
- 1Calculate your real hourly wage after taxes and costs of working.
- 2Before a discretionary purchase, divide its price by that figure to get life-hours.
- 3Ask whether the thing is worth that many hours of your life, then decide.
What the evidence says
MechanisticThis is the central tool of Your Money or Your Life; it is a mechanistic reframing of opportunity cost rather than a clinically tested intervention. Related research shows people systematically under-weight opportunity costs.
Honest caveat: The hourly-wage conversion is a heuristic; its value is shifting the frame, not producing a precise number.

Common mistake
Using a gross hourly wage that ignores taxes and the costs of working, which understates the true life-hour price and weakens the reframing.
