The Coinbase Fee is the greater of a flat fee or a percentage fee based on the transaction amount and payment method. For US Dollar transactions: $0.99 for transactions from $0.00-$9.99; $1.49 for $10.00-$24.99; $1.99 for $25.00-$49.99; $2.99 for $50.00-$199.99. For transactions $200 and over, the percentage fee structure applies. Coinbase may charge a different fee for using different payment methods (e.g. bank account, debit card).
The flat fee structure disproportionately penalizes small transactions, meaning casual investors or those testing the platform with small amounts pay the highest effective percentage cost.
Every time you buy, sell, or convert cryptocurrency on Coinbase, you pay at least two layers of cost: a spread embedded in the displayed price plus an explicit Coinbase Fee, meaning the true cost is higher than the price shown before you preview the transaction. Debit card purchases incur significantly higher fees than bank account transactions, making payment method selection a material financial decision. You can reduce your fees by using a linked bank account instead of a debit card and by reviewing the full fee breakdown on the transaction preview screen before confirming.
