In Beyond Money you will find a reference to the Bitcoin purchasing power calculator, here it is! 🙂 I’m really excited about this tool because it visualizes something most people never consider: how your purchasing power has actually changed in Bitcoin terms over the past 8 years compared to fiat currency.
Important Notices: This tool was designed for larger screens and will not work on moble, please use it on tablet or desktop. All calculations run locally in your browser. Nothing you enter is stored or transmitted. Current Bitcoin–USD value is fetched from CoinGecko (with fallbacks to Coinbase and Kraken) and cached on my server for 30 minutes. These tools pull the price from the cache.
How to use this calculator
Enter your monthly or yearly cost of living in both tables below (use the same format in both). Include rent, utilities, groceries, transportation, and leisure. If you need to convert your costs to USD, use a free tool like XE’s currency converter.
Step 1: Enter your costs today.

Your Bitcoin Purchasing Power
Why This Matters
This exercise usually reveals something striking: your purchasing power in Bitcoin has likely increased dramatically, even though your fiat costs have risen. That's because Bitcoin operates as a true free market where prices fall toward the marginal cost of production.
- In Bitcoin terms, your cost of living actually decreases over time
- Your purchasing power increases
- You can buy more goods and services with the same amount of Bitcoin
This is the opposite of what happens with fiat currency, which is why it can feel counterintuitive.
Another Real-World Example
Below is a table showing how actual consumer goods have changed in cost—both in USD and in sats—from 2015 to 2024:
| Item | Historic (USD) | Oct. 2024 (USD) | Historic (Sats) | Oct. 2024 (Sats) |
|---|---|---|---|---|
| Coffee (8 oz) | $2.50 | $5.00 | 40,000 | 7,600 |
| Big Mac | $4.50 | $5.99 | 72,000 | 9,200 |
| Average Rent (1BR) | $1,200 | $2,000 | 19,200,000 | 3,000,000 |
| Gas (gallon) | $3.50 | $4.00 | 56,000 | 6,000 |
| Movie Ticket | $10.00 | $15.00 | 160,000 | 23,000 |
| Restaurant Meal | $20.00 | $30.00 | 320,000 | 46,000 |
*Historic USD is based on prices from October 2015 while current prices are based on values in October 2024. USD prices are based on averages pulled from various online resources.
In October 2015, a coffee cost 40,000 satoshis. Eight years later, the same coffee costs 80% less in Bitcoin—just 7,600 sats. Meanwhile, in USD it costs twice as much. This gap is the key insight: while prices are rising in fiat, they're falling in Bitcoin.
