This tool estimates your chances of mining a Bitcoin block on your own. Solo mining is basically a lottery: you’re hashing against the entire network, hoping to find the next valid block before everyone else does. This calculator gives you a clear view of those odds:

How it works
Every ten minutes or so, someone on the network finds a block - and Bitcoin’s difficulty adjustment keeps this timing fairly consistent. Your chance of being that someone is determined by your share of global hashrate. If you have 1 TH/s and the network has 1,000,000,000 TH/s, your odds per block are one in a billion.
The calculator uses the current network hashrate, recent block data, and the latest block reward (subsidy + fees) fetched from mempool.space. From that, it derives your expected time-to-win expressed as probabilities over various time periods.
A quick reality check: these are probabilities, not promises. A tiny Bitaxe miner could hit a block tomorrow and bag the whole reward for themselves. This does occasionally happen. They might also mine for 500 years and get nothing. That’s the nature of proof-of-work (and the enormous amount of energy securing the Bitcoin network).
Solo mining isn’t about predictable income; it’s about taking a shot at the full block reward instead of sharing it among pool contributors. Here you can see the real odds for your hashrate.
Enjoy - and happy hashing.
