- Does this calculator include fees and taxes?
- No — it is pure arithmetic on daily closes: no exchange fees, spreads or taxes. Real-world results would be slightly lower; check your country’s rules in the SatsAtlas tax directory.
- Why does it also show the result in sats?
- Because the dollar value moves every day, but the sats you bought never change. Measuring in sats is how this site separates Bitcoin’s volatility from the fixed amount you actually own.
