How to Use This Tool
- Step 1 - Enter the item's price (e.g., $999 for a new phone)

Why Think in Time Instead of Money?
Your brain is numb to dollar amounts. Saying "$1,200" doesn't trigger emotional weight. But saying "60 hours of work" (1.5 work weeks) makes you viscerally feel the sacrifice. This time-based pricing technique comes from behavioral economics framing costs in time reduces impulse purchases by 30%+.
The formula is simple: Item Price ÷ Hourly Wage = Hours of Life. If you make $25/hour after tax, a $500 purchase costs 20 hours of work (2.5 days). The tool also calculates cost per day if you enter usage duration e.g., a $1,200 phone lasting 2 years costs $1.64/day.
Pro tip: Use your after-tax wage, not gross salary. If you earn $60k/year gross, your take-home might be $45k (~$22/hour). Factor in commute time too if you work 8 hours but commute 2 hours, use 10 hours total.
