True Cost per MorningDev

Is that €79 jacket really worth it? True Cost shows you: it's 5 hours and 16 minutes of your work.

True Cost is a simple browser extension that converts product prices on any website into work-time equivalents, based on your net hourly wage.

HOW IT WORKS
1. Set your hourly wage in the settings popup
2. Browse any online shop — Amazon, Zalando, eBay, Otto, or any site with prices
3. Prices are automatically converted into work-time (e.g. "3h 12m" instead of "€79,99")

The converted text appears in the exact same font, size, and color as the original price — it blends in perfectly and looks completely native.
