About Opportunity Cost Widget
Stop spending money. Start spending time.
We’ve all been there—mindlessly adding $20 items to our Amazon cart. It doesn’t feel like “real money.” But what if you saw the real cost?
This Chrome extension replaces the price tag on Amazon with how many hours you have to work to pay for it. Suddenly, that $200 gadget isn’t just “$200”—it’s two days of your life.
What does it do?
Real-time conversion: Instantly converts prices into “work hours” based on your salary.
Investment forecaster: Shows how much that money could grow if invested in the S&P 500 instead.
Smart formatting: Small purchases show as “hours,” while big purchases (like laptops) show as “days.”
Private storage: Your salary data stays in your browser (Chrome Sync). It never leaves your device.
