Ultimate Guide To Understanding Bitcoin’s Fee-to-Reward Ratio


The Bitcoin fee-to-reward ratio is the proportion of a miner’s income from transaction costs to the total block reward. Divide the transaction fees by the total block reward, which includes both the block subsidy and the transaction fees, to get the balance.

The ratio significantly impacts the health and security of the Bitcoin network as the block subsidy continues to halve over time to reach zero in 2140 eventually. In early 2023, activities relating to BRC-20 tokens pushed Bitcoin’s fee-to-reward ratio to over 50%, a rare occurrence.

Understanding Bitcoin’s Block Reward: A Concise Explanation

Understanding The Block Subsidy: An Overview

Bitcoin’s Proof of Work (PoW) consensus mechanism relies on miners dedicating substantial computational resources to solve intricate calculations necessary for incorporating new blocks into the blockchain.

This process safeguards the network’s security while incentivizing miners through a fixed allocation of freshly minted bitcoins for each added block. These newly generated bitcoins originate from a specific coinbase transaction, typically occupying the central position within a block and creating coins seemingly out of thin air due to the absence of input sources.

Bitcoin Miners & Computational Commitment:

Within Bitcoin’s PoW consensus mechanism, miners play a crucial role by devoting considerable computational resources toward solving complex calculations that facilitate the inclusion of new blocks in the blockchain.

Block Subsidy & Incentivization:

A block subsidy rewards miners for their efforts by granting them a predetermined quantity of newly minted bitcoins. This incentive is given for each successfully added block, reinforcing miners’ commitment to maintaining the security and stability of the Bitcoin network.

The Role Of Coinbase Transactions:

The creation of newly minted bitcoins occurs through a specialized coinbase transaction. Typically occupying the initial position within a block, this transaction generates coins “out of nothing” due to the absence of traditional input sources.

By adopting the provided rephrasing and incorporating a new subheading, we can more effectively organize the information regarding Bitcoin’s Proof of Work consensus mechanism, block subsidy, and coinbase transactions. This approach allows us to enhance the organization of the information and improve its clarity. Moreover, it enables us to present the details of Bitcoin’s Proof of Work consensus mechanism, block subsidy, and coinbase transactions more coherently and structured.

What Are Transaction Fees?

Understanding Bitcoin Transaction Fees and Block Rewards

Bitcoin transactions entail paying a modest fee to miners to execute the transaction. These fees are crucial in determining the priority and inclusion of transactions in the Bitcoin network’s blocks. They will explore the dynamics of Bitcoin transaction fees and block rewards in this article, emphasizing the importance of distinguishing between them.

Bitcoin Transaction Fees: A Bidding System

Bitcoin transaction fees operate on a bidding system, wherein users attach higher costs to their transactions to increase the likelihood of miners including them in the next block. This approach ensures that transactions with higher fees are prioritized during times of high demand on the network.

Differentiating Block Rewards & Transaction Fees

Initially, people used to interchangeably use the terms “block reward” and “block subsidy” to describe the total amount miners receive after successfully mining a block. However, as transaction fees on the Bitcoin network continue to rise, it becomes increasingly crucial to distinguish between these two components.

The Block Reward Formula

We will use the following terminology to promote clarity in our discussion:

Block reward = block subsidy + transaction fees

Understanding Bitcoin transaction fees and block rewards is crucial in comprehending the functioning of the Bitcoin network. By differentiating between block rewards and transaction fees, we can appreciate the evolving role of costs in the overall compensation received by miners. This knowledge enhances our understanding of the Bitcoin ecosystem and its economic dynamics.

Mastering The Calculation Of Fee-to-Reward Ratios

The fee-to-reward ratio is commonly represented as a percentage and is determined by dividing the transaction fees by the block reward using the following formula:

Fee-to-reward ratio = transaction costs/block reward X 100%

It can also be written as:

Fee-to-reward ratio = transaction fees/block reward

The Necessity Of Block Rewards: Understanding Their Purpose

Block incentives incentivize miners to devote computing resources to operationalizing the Bitcoin network. Newly generated bitcoins and bitcoins earned through transaction fees reward miners for their dedication. The block reward design is critical to Bitcoin’s tokenomics because it maintains a regulated introduction of new bitcoins into the system at a decreasing pace.

This generates a deflationary economic paradigm that mirrors precious metal mining, where the new metal becomes harder to locate. According to the Bitcoin protocol’s coding, it also assures that no more than 21 million bitcoins will ever exist.

Understanding The Concept Of Bitcoin Halving

The fee-to-reward ratio is gaining popularity, thanks in part to the Bitcoin halving phenomenon, which refers to the occurrence in which the block subsidy miners stand to get halves about every four years.

The block subsidy of Bitcoin started at 50 BTC and has been halved every 210,000 blocks, or approximately every four years. In 2012, they reduced Bitcoin contributions to 25 bitcoins. In 2016, they further reduced Bitcoin contributions to 12.5 bitcoins. In 2020, they reduced Bitcoin contributions to 6.25 bitcoins. In 2024, they hope to reduce it to 3.125 BTC.

The Significance Of Fee-to-Reward Ratio In Safeguarding Bitcoin’s Security

Miners expect to mine the last bitcoin around 2140 at this pace of halving. Miners will no longer get block subsidies at that time but will be rewarded only through transaction fees.

Even though that potential situation is still several years away, some have questioned whether transaction fees would rise sufficiently to compensate miners adequately without block subsidies.

As block subsidy falls to 3.125 BTC in 2024 and 1.5625 BTC in 2028 – levels much lower than the previous decade – this topic appears to be relevant soon.

Exploring Bitcoin’s Fee-to-Reward Ratio: A Glimpse into the Future

The Bitcoin network has had a fee-to-reward ratio in the low single digits for most of its existence. Transaction fees have traditionally contributed minimally to miners’ overall revenue.

However, establishing transaction fees is influenced by various factors, including supply and demand dynamics. Users compete by paying more outstanding transaction fees when the demand for block space on the Bitcoin network increases. They do this to guarantee that their transactions appear in the following block.

Increased Demand & Fee Surge:

Notably, specific periods, such as 2017 and 2020, experienced substantial hikes in transaction fees. A surge in mainstream adoption, fluctuations in Bitcoin price, and network congestion likely caused these spikes. As more users sought to utilize the limited block space, the competition for inclusion resulted in escalated transaction fees.

BRC-20 Tokens & The Historical Fee-to-Reward Ratio:

In early 2023, introducing BRC-20 tokens led to an unprecedented surge in Bitcoin’s fee-to-reward ratio, reaching new historical highs. This ratio surpassed 50%, signifying that transaction fees within a block exceeded the block subsidy—a rarity. In the long run, questioning the maintenance of such an abnormally high fee-to-reward ratio is important.

The fee-to-reward ratio within the Bitcoin network has historically remained low. Transaction fees play a minor role in miners’ revenue. Surges in transaction fees have occurred during periods of increasing demand and network congestion. These surges were particularly notable between 2017 and 2020.

Moreover, introducing BRC-20 tokens in early 2023 resulted in an extraordinary fee-to-reward ratio, surpassing 50%. While this occurrence is remarkable, its sustainability remains uncertain.


Transaction fees account for 100% of miners’ earnings when the block subsidy hits zero. Before that, transaction fees may need to climb progressively. They should attain stable, sustainable growth. This will ensure mining remains profitable enough to entice miners to engage in the Bitcoin network.

The requirement to raise the fee-to-reward ratio should accomplish this balancing. If the transaction costs are kept low enough, users ought to accept them.
