Sats per dollar
The number of sats $1 buys is just 100,000,000 divided by the bitcoin price. It's a handy way to think about small amounts: when bitcoin's price rises, a dollar buys fewer sats; when it falls, more.
Buying $1 of bitcoin in practice
Many exchanges set a minimum purchase above $1, and a flat fee of even $0.50 would be half your money. Where you'll most often see a dollar or less turn into bitcoin is through rewards programs, "round-up" features and Lightning tips, where the sats are credited to an account rather than bought separately. Whatever the route, check what you're charged.
Don't withdraw tiny amounts on-chain
A single on-chain withdrawal fee can be worth more than a dollar of bitcoin. If you're collecting small amounts, let them add up first, or use a Lightning wallet.
