Understanding Probability

Probability is not a guarantee. In solo mining, each hash is an independent attempt: having mined for hours, days, or months without finding a block does not by itself increase the odds of the next attempt. Your probability depends primarily on your hashrate relative to the network difficulty and total hashrate, and it changes whenever the network difficulty adjusts.

Even a very low probability is not zero, but that does not mean a result is likely within any calculated period. OwnBlock has conducted lab tests that demonstrate how solo mining works with modest hardware; those tests should not be interpreted as a guarantee of profitability or a promise of finding blocks on mainnet.

Use this calculator to set realistic expectations and understand statistical risk, not to predict exact outcomes.

Tool guide

Solo Mining Probability Calculator for XMR, BCH and BTC

Estimate your real chance of finding a block

The OwnBlock calculator helps miners estimate the likelihood of finding a block in a solo mining pool for Monero (XMR), Bitcoin Cash (BCH) and Bitcoin (BTC). In solo mining, the miner who finds the block receives the full block reward, minus the pool fee. The calculation uses a Poisson model to give a realistic probability based on your hashrate, mining time and current network conditions.

Mining estimates for Monero, Bitcoin Cash and Bitcoin

Choose your coin and enter your hashrate to compare your power with the global network hashrate and estimate the chance of finding at least one block. Whether you need a mining calculator for Monero, a BCH solo mining estimate or a mining calculator for Bitcoin, OwnBlock gives you clear real-time figures before you connect your hardware.

Rented hashrate, algorithms and pools

Rented hashrate and NiceHash solo mining

You can also model scenarios using rented hashrate from marketplaces such as NiceHash. The rental mode works as a hashrate rental calculator: enter the speed, unit, price and duration to estimate block probability and expected return. It is designed for NiceHash solo mining, where miners rent temporary hashrate and point it to an OwnBlock solo pool for a short, high-variance session.

Algorithms, fees and OwnBlock pools

OwnBlock operates dedicated pools for Monero (XMR), Bitcoin Cash (BCH) and Bitcoin (BTC). Monero uses a RandomX mining pool with MH/s or GH/s units, whilst BCH and BTC use SHA-256 AsicBoost with PH/s or EH/s. No KYC is required, and a 2% fee applies only when a block is found.
