About this tool

How Much Does It Cost? is a Chrome extension that removes the mental math from shopping in foreign currencies. Install it once, browse any site, and every price becomes immediately meaningful.

The extension automatically detects prices on any webpage you visit — Amazon, Booking.com, eBay, Etsy, Airbnb, and countless Shopify stores. It recognizes prices in any format: $50, 100€, 5000¥, 10000₽, ₿, and more.

Hover over any detected price to see:

- Live conversion into multiple currencies side by side
- What that price actually buys locally — cups of coffee, lunches, hotel nights, or months of rent in your city
- How many hours of work that purchase costs (set your hourly rate once and get a perspective that changes how you spend)
Built with privacy first. No accounts, no sign-ups, no tracking. All price detection happens locally in your browser — nothing is sent anywhere.
Key features:
- Works on all websites automatically
- 50+ supported currencies with daily rate updates
- Cost-of-living comparisons using real local data
- 8 languages
- Light and dark theme
- Premium one-time purchase ($9.99) for savings goals, custom categories, and budget alerts
