Educational estimates only—not financial, tax, or investment advice. Spot prices and network conditions change.
Purchase sizing without a cart
Enter the fiat you plan to spend. We divide by spot to estimate BTC. Your exchange will still charge spread, fees, and possibly a deposit rail cost.
Sats for small buys
Sub-$50 buys look clearer in sats. We show both so you can compare with faucet-scale stacks.
Examples
- See how much BTC $250 buys at current spot.
- Convert a paycheck slice to sats before setting a recurring buy.
FAQ
- How much Bitcoin is $100?
- Divide 100 by the live BTC/USD price. The converter does that and also shows sats. The result updates as spot moves.
- Is this a buy button?
- No. It is a sizing tool. To purchase BTC, use a licensed exchange that serves your jurisdiction—then withdraw to self-custody when ready.
