When you use a cryptocurrency like Bitcoin or Ethereum, you need to pay a small fee for each transaction. This fee is known as a gas fee, and it goes to the miners who process and confirm the transactions on the blockchain. Gas fees are usually very small, but they can add up if you’re making a lot of transactions. That’s why it’s important to understand how they work before using cryptocurrencies.

An Overview of Gas Fees

When people talk about gas fees, they refer to payments that individuals need to make to complete a transaction on the blockchain itself. In general, these fees are designed to compensate miners, who spend a lot of their resources verifying blockchain transactions and adding new blocks to the chain itself. Even though the vast majority of people agree that miners need to be compensated for their time, the gas price can vary widely depending on many factors. What determines how ETH gas fees are calculated?

How Are ETH Gas Fees Calculated?

In general, two main factors will dictate the cost of gas fees on the ETH chain. These include the block time and the transaction throughout. The block time refers to the time it takes for the ETH blockchain to generate a new block. Then, the transaction throughput refers to the number of transactions a single block can process. The faster blocks are generated, and the more transactions each block can hold, the lower the transaction fees will be.


For example, the ETH chain has a block time of 13 seconds and a block size of about 70 transactions. ETH is one of the most popular blockchains in Web 3. It has a high network usage and a very low block size. This means that new blocks must be mined regularly, which is why transactions on the ETH blockchain have become more expensive. The gas fees on the ETH chain are relatively simple. The total gas fee is equal to the gas units (the limit of the transactions) times the base fee. Some users even add a tip. If there is a gas war for a popular NFT, users will raise their gas limits, further driving up the price.

Looking for More Affordable Options

The ETH team has announced a multi-phase ETH 2.0 upgrade, which is designed to be more scalable. This could help people save money on their gas fees.
There is also the option for people to explore sidechains. This separate blockchain network connects to the original blockchain using a two-way bridge. It uses tools such as smart contracts to transfer tokens securely and operates under its consensus protocol. This could be another way for users to save money on gas fees.

We advise you to monitor the gas fees because they fluctuate depending on the time of day. The Bottom Line: Gas fees are a necessary part of using the Ethereum network, and they’re likely to continue rising as the network grows. However, there are a few blockchains with low gas fees like Solana, Cardano, Polygon.
