Crypto buying-cost calculator
Enter how much you want to spend. We estimate the fee and spread on each US exchange and show how much crypto you would actually receive.
We may earn a commission from "Visit" links. Results are sorted by estimated cost only. "Estimate" means the platform doesn't publish that fee and we used independent reviews. Always check the preview screen before you confirm.
What this calculator counts
Trading fee. A flat or percentage charge the platform shows as a separate line, such as Kraken's 1% instant-buy fee or Cash App's tiered fee table.
Spread. The difference between the price you're quoted and the market price. Apps that advertise "no commission" make their money here. Few platforms publish their spread, so we use the figure they state where available and independent review estimates where not.
Payment method. Debit cards usually add 1.5% to 4%. Bank (ACH) transfers are free on every platform listed.
What it leaves out
Withdrawal and network fees when you move coins to your own wallet, wire fees, and the fee you pay later when you sell. Prices also move between your quote and your order.
