A Bitcoin transaction fee is a small amount of BTC that a user pays to have a transaction processed and confirmed on the Bitcoin network. The size of the fee directly affects how fast the transaction is confirmed: higher fees usually mean faster processing, especially when the network is busy.
Key Takeaways
Bitcoin transaction fees set the priority of a transaction in the network: higher fees usually mean faster confirmation.
The fee depends on network congestion and transaction size (in virtual bytes), not on the amount of BTC sent.
Lower fees reduce costs but can lead to long confirmation times during periods of high network activity.
To keep Bitcoin transaction fees simple and easy to understand, below we break down the main points:

What Is a Bitcoin Transaction Fee?
A Bitcoin transaction fee (also called a network fee or miner fee) is a small amount of BTC that the sender pays to miners for processing and confirming transfers on the network. In simple terms, this fee is required for a transfer to be added to the blockchain. When you send Bitcoin, your transfer first enters the mempool, where miners select it for inclusion in the next block.
Miners are participants in the Bitcoin network who confirm transactions and keep the blockchain running. For their work, they receive rewards, including Bitcoin transaction fees.

What Is the Bitcoin Mempool and How It Affects Fees
The Bitcoin mempool is a queue of unconfirmed BTC transactions that have already been sent to the network but have not yet been added to a block. Until miners process a transaction, it stays in the mempool and waits its turn. Unlike blockchains such as Solana, TRON, or BNB Chain, where transactions are usually confirmed almost instantly due to high network capacity and no classic queue, Bitcoin’s transaction speed depends directly on the fee and current network load.
Pros of the Bitcoin Mempool
Higher fees usually mean faster confirmation.
You can save funds if your transfer is not urgent and you are willing to wait.
Cons of the Bitcoin Mempool
During busy periods, transactions become slower.
With a low fee, a transfer can get stuck for hours or even days.
Bitcoin Transaction Stuck: What to Do If Your Transfer Is Pending
If the Bitcoin fee is too low, your BTC transfer can get stuck in the mempool without confirmation. To avoid this, it is better to choose more than the minimum fee or send Bitcoin when the network is less busy and miners can process your transaction faster.
How to Calculate a Bitcoin Transfer Fee?
A Bitcoin transaction fee consists of two simple parts:
- sat (satoshis) - the smallest unit of BTC. This is what you pay the Bitcoin transfer fee in.
- vB (virtual bytes) - the data size of a transaction. The more data a transaction contains, the higher the BTC transaction fee.
Bitcoin fees are calculated as:
transaction size (vB) × fee rate (sat/vB)
The higher the fee rate in sat/vB, the higher the transaction priority and the faster it is confirmed. In simple terms, you are not paying for how much BTC you send, but for how much block space your transaction uses.

How Much Is a Bitcoin Fee in USD?
In normal network conditions, a typical Bitcoin transaction fee is usually between $0.02 and $2.00, depending on the current BTC price.
We prepared a table with estimated Bitcoin transaction fees for one BTC transfer at different BTC prices. For our calculations, we used the median fee paid by most users (about 1.4 sat/vB, usually in the 1-2 sat/vB range) and an average transaction size of around 140 vB under moderate network congestion. These amounts in USD are for reference only - actual fees may change depending on network activity and miner demand.
Estimated Bitcoin Transaction Fee in USD (One BTC Transfer)
| BTC Price | Fee (sats) | Fee (BTC) | Fee (USD) |
|---|---|---|---|
| $10,000 | 200 | 0.000002 | $0.02 |
| $100,000 | 200 | 0.000002 | $0.20 |
| $250,000 | 200 | 0.000002 | $0.50 |
| $500,000 | 200 | 0.000002 | $1.00 |
| $1,000,000 | 200 | 0.000002 | $2.00 |
How Do Bitcoin Network Fees Work?
Blocks on the Bitcoin network are created regularly, but the space inside them is limited. When many people send BTC at the same time, they compete for space in the next block, and transaction fees go up. That’s why Bitcoin fees work in a simple way: transfers with higher fees are confirmed faster.
Why Do Bitcoin Transaction Fees Exist?
At first glance, it may seem logical to make Bitcoin transfers free. However, there are two main reasons why the network works differently. Fees are an incentive mechanism that keeps Bitcoin decentralized and secure.
Paying Miners and Securing the Network: Miners confirm transactions and spend electricity and hardware resources to do so. That is why the sender pays BTC fees: these fees compensate miners for their work and help keep the network secure.
Protection Against Spam: Without fees, the network could be overloaded with millions of small transactions. This is why Bitcoin transaction fees exist - they help the Bitcoin network remain stable and reliable.
How to Choose a Bitcoin Fee in a Wallet
In most Bitcoin Wallets, users can choose between low, medium, and high fee levels, depending on how fast they want their BTC transaction to be confirmed.
In Gem Wallet, this can be done in just a few clicks. Since the wallet is a mobile self-custody solution with open-source code, it does not charge any extra fees - you only pay the network fee. This is different from exchanges, which often add their own fees on top of the Bitcoin network fee.
Depending on whether you want to send BTC or swap BTC to Ethereum, Solana, or BNB (the wallet supports more than 100 blockchains and 10M+ tokens), you can choose the appropriate fee level. The wallet interface offers different options, from low to high. This allows you to either speed up transaction confirmation or save on Bitcoin fees if there is no urgency.
The table below shows the fee priority levels in Gem Wallet.
Fee Priority Levels in Gem Wallet
| Priority | Typical Fee Range | Confirmation Time | Best For |
|---|---|---|---|
| Low (Economy) | 1-5 sat/vB | 30-60 minutes or longer | Non-urgent transfers, savings deposits |
| Normal (Standard) | 10-20 sat/vB | 10-30 minutes (1-3 blocks) | Regular transactions, most use cases |
| High (Fast) | 30-100+ sat/vB | 0-10 minutes (next block) | Urgent payments, time-sensitive transfers |
In summary, Bitcoin fees depend on transaction size, network congestion, and how fast you want your transfer to go through. In Gem Wallet, you can track your transaction status in real time. If your BTC transfer is stuck because of a low fee, you can contact support - real people, not bots - and they will help you resolve the issue.
