Ethereum mining has long been a popular way for individuals to participate in the blockchain ecosystem and potentially earn digital assets. However, with changes in network protocols and hardware requirements, many new miners often ask: How many Ethereum can be mined in a day? And more specifically, how long does it take to mine one full ETH? This guide breaks down the key factors affecting mining output and provides realistic estimates based on current conditions.
Understanding Ethereum Mining Output
Before diving into specific numbers, it's important to clarify that Ethereum transitioned from a proof-of-work (PoW) consensus mechanism to proof-of-stake (PoS) in 2022 through "The Merge." As a result, traditional GPU or ASIC mining of ETH is no longer possible. However, some networks or forks still support ETH PoW mining, and many users continue to explore mining on these alternative chains.
For the purpose of this article, we'll focus on historical and technical insights relevant to Ethereum mining performance under PoW, while also addressing modern alternatives for earning ETH.

Key Factors That Affect Mining Output
Several variables determine how much Ethereum a miner can generate daily:
- Hashrate (Mining Power): Measured in megahashes per second (MH/s), this reflects your hardware’s processing power.
- Network Difficulty: The higher the difficulty, the harder it is to mine blocks.
- Power Consumption & Electricity Cost: Impacts profitability more than raw output.
- Pool Fees: Most miners join pools, which charge small fees for consistent payouts.
- Hardware Efficiency: Newer GPUs like the NVIDIA RTX 3060 Ti or AMD RX 6700 XT offer better hashrates per watt.
Even though native ETH mining is obsolete, understanding these metrics remains valuable for those exploring other proof-of-work cryptocurrencies or Ethereum Classic (ETC).
Estimated Daily Mining Output by Hardware Tier
While exact figures vary over time due to fluctuating network conditions, here are approximate daily yields based on different hashrate levels when Ethereum was actively mined:
4GB VRAM GPUs – Around 50–60 MH/s
GPUs with 4GB of memory were once widely used for Ethereum mining. However, as the DAG file size grew beyond 3.9GB, most 4GB cards became inefficient or non-functional. Prior to obsolescence:
- Daily output: ~0.005–0.007 ETH per card
- Note: These devices are now largely outdated for ETH mining.
100 MH/s Setup – Entry-Level Rig
A typical single GPU setup (e.g., GTX 1660 Super or P106-100):
- Daily output: ~0.007–0.008 ETH
- Monthly total: Approximately 0.21–0.24 ETH
- At peak prices, this could equate to hundreds of dollars monthly—before electricity costs.
110 TH/s (Typo Clarified: Likely 110 MH/s)
There appears to be confusion in the original text where “110 TH/s” is mentioned—this is unrealistically high for consumer hardware. Assuming it meant 110 MH/s, typical for a multi-GPU rig:
- Daily output: ~0.011 ETH
- Based on average block rewards and network stats pre-Merge
High-End Rigs (6x GPU Setup)
A standard 6-GPU mining rig using efficient cards:
- Total hashrate: ~120 MH/s
- Daily output: ~0.01–0.012 ETH
- Monthly yield: ~0.3–0.36 ETH
These numbers assume stable network conditions and exclude downtime or pool fees.
How Long Does It Take to Mine 1 Ethereum?
Given an average daily output of 0.01 ETH from a mid-tier rig:
- It would take approximately 100 days to mine one full Ethereum.
For a high-performance rig producing 0.012 ETH/day, the timeline shortens to about 83 days.
Keep in mind that solo mining a full block is extremely unlikely without massive computational power. Most miners earn fractional rewards through pooled mining.

Frequently Asked Questions (FAQ)
Q: Can I still mine Ethereum in 2025?
No. Ethereum completed its transition to proof-of-stake in September 2022 ("The Merge"). Traditional mining via GPUs or ASICs is no longer supported on the mainnet.
Q: What happened to Ethereum miners after The Merge?
Many miners migrated to alternative PoW chains like Ethereum Fair, EthereumPoW (ETHW), or shifted to mining other coins such as Ravencoin, Ergo, or Beam.
Q: Is mining Ethereum Classic (ETC) profitable?
ETC remains a viable PoW coin. Profitability depends on electricity cost, GPU efficiency, and market price. Use online calculators to assess potential returns.
Q: How much ETH did miners earn per day before The Merge?
Top-tier rigs (120+ MH/s) earned roughly 0.01–0.015 ETH/day at peak efficiency, translating to $30–$50 daily during bull markets.
Q: Why did 4GB GPUs stop working for Ethereum mining?
The Ethash algorithm requires increasing DAG file sizes. Once the file exceeded 3.9GB, 4GB VRAM cards could no longer handle the load efficiently.
Q: Can I use old mining hardware for anything now?
Yes. Repurpose older GPUs for gaming, rendering, or mining lighter coins like Dogecoin (scrypt-based) or Zcash (Equihash).

Final Thoughts
While you can no longer mine native Ethereum on the mainnet, understanding past mining dynamics helps inform decisions about alternative cryptocurrencies and investment strategies. Whether you're evaluating old hardware, considering ETC mining, or exploring staking options, knowledge of hashrates, energy costs, and network trends remains essential.
Although the era of home-based ETH mining has ended, new opportunities emerge constantly in decentralized finance, staking, and next-generation blockchains. Staying informed ensures you remain positioned for future growth in the evolving crypto landscape.
