Easily see how much things cost in Bitcoin.

👋 Hey Product Hunt!

I’m Ben, the solo creator of Bitcoin Opportunity Cost Calculator, and I’m thrilled to launch this today.

The Problem:

We’re living in turbulent financial times. Fiat currency feels like a melting ice cube, tempting us to justify impulse buys with, “Well, money’s losing value anyway.” Whether it’s a conscious thought or a lack of financial discipline, those small purchases add up—death by a thousand cuts. I built this to help everyone see the real impact of their spending in an instant.

What Bitcoin Opportunity Cost Does:

👉 Customize and save your CAGR (Compound Annual Growth Rate) and timeframe preferences.

👉 Instantly convert any highlighted price into its BTC equivalent with real-time data.

👉 Visualize the future value of that BTC based on your settings, turning “what if” into action.

👉 Inspire smarter choices with a “Buy with Bitcoin” prompt.

How It Works:

This Chrome extension is sleek and powerful. Highlight any price online, Amazon, Apple, Nike, news sites, anywhere and a non-intrusive pop-up reveals the BTC value and its projected growth.

It’s powered by:

Local Storage: Tracks conversions and webpage context.

Session History: Logs timestamps and highlights order.

Together, it’s your personal financial mirror, queryable, memorable, and eye-opening.

Who It’s For:

⚡ Bitcoin HODLers, stackers, and anyone craving financial clarity, enhance your spending decisions with Bitcoin-first insights.

Why Now:

With Bitcoin hitting new highs and fiat inflation eroding purchasing power, today’s the day to rethink every dollar spent. Launched on this date, this tool aligns with the market’s momentum, giving you the edge to stack sats smarter.

Who We Are:

I’m a Bitcoin enthusiast and solo dev, fueled by a passion for financial sovereignty. Using @Cursor @Grok 3 @UXPile and UX Pilot, I crafted this extension to blend seamlessly into your workflow, a lesson from my journey that tools succeed when they disappear into daily life.

Playground:

Dive in! Grab it from the Chrome Web Store, highlight a price (e.g., that £528 Mac Mini), and see the BTC breakdown unfold. No setup, no fuss, just pure financial truth.
