Solo Mining Time Estimator
Estimate how long it would take to solo mine a Bitcoin block with your hashrate. Calculate probabilities and expected time based on current network difficulty.
Could you mine a Bitcoin block on your own?
Calculate the expected time and probability of solo mining a block — with real network difficulty data.
Solo mining means mining Bitcoin without joining a pool -- you keep the entire block reward (currently 3.125 BTC) if you find a block, but the odds are extremely low for most miners. This calculator uses real-time network difficulty to estimate how long it would take your hardware to find a block on its own, and shows the probability of success over various timeframes.

How Solo Mining Works
In Bitcoin mining, every miner competes to find a valid block hash. This process involves repeatedly hashing block data with different nonce values until a hash is found that meets the network's difficulty target. When you mine solo, you compete directly against the entire network without pooling resources with other miners.
The Lottery Analogy
Solo mining is like playing a lottery where each hash attempt is a ticket. Your hashrate determines how many tickets per second you buy. With higher difficulty, you need more tickets (hashes) to have a chance of winning.
Network Difficulty
Difficulty adjusts every 2,016 blocks (~2 weeks) to maintain a 10-minute average block time. As more miners join, difficulty increases, making it harder for any single miner to find a block. Current difficulty is in the trillions.
Block Reward
The current block reward is 3.125 BTC (after the April 2024 halving). This reward halves approximately every 4 years. Solo miners keep the entire reward plus transaction fees, but must find the block first.
Understanding Mining Probability
Mining follows a Poisson process -- each hash attempt is independent, and finding a block is a random event. Even if the expected time is 100 years, there is a tiny chance you could find a block in the next second. Conversely, you might mine for twice the expected time and still find nothing. This randomness is fundamental to how Bitcoin works.
The Formula
The expected time to find a block is: expectedTime = (difficulty * 2^32) / hashrate. This gives you the average number of seconds before finding a block. The probability of finding at least one block in time t is: P = 1 - e^(-t/expectedTime).
Expected Value vs Reality
The "expected time" is a statistical average. With a single ASIC, your expected time might be hundreds of years. This does not mean you need to wait hundreds of years -- you might get lucky tomorrow. But it also means you could run your miner for decades without ever finding a block. The expected daily earning from solo mining is mathematically identical to pool mining (minus the pool fee), but the variance is astronomically higher.
Why Pools Exist
Mining pools solve the variance problem by combining hashrate from thousands of miners. When the pool finds a block, the reward is split proportionally based on each miner's contribution. You earn less per block (due to the pool fee and shared reward), but you earn consistently. For most miners, the steady income from pool mining is far more practical than the lottery of solo mining.
When Does Solo Mining Make Sense?
Despite the overwhelming odds, some miners choose to go solo. Here are the scenarios where it might make sense:
Might Work
- You have multiple PH/s of hashrate
- You want to avoid pool censorship
- You want to support decentralization
- You treat it as a long-term lottery
Probably Not
- You need consistent income
- You only have one or a few ASICs
- You are paying for electricity
- You want predictable ROI calculations
Important Disclaimer
These calculations are statistical estimates only. Mining is a probabilistic process -- actual results can vary dramatically from expected values. Network difficulty changes approximately every two weeks, which will alter these estimates. Electricity costs, hardware failures, and other operational factors are not included in this calculation. This is not financial advice.
