Solo Bitcoin Mining Odds Calculator
Plug in your hashrate and pool choice to get rough estimates for how long it might take to find a block solo — plus the probability of finding at least one block over different time windows. This is just math on top of the current network snapshot, not a guarantee of anything.

Important note
This is a toy model for estimating solo-mining odds — not financial advice, not a guarantee, and not a promise that your luck will behave. Bitcoin doesn’t care about our spreadsheets.
More from me
I'm Mike (ProofOfMike), running a small home Bitcoin mining setup and sharing the real numbers — good luck streaks, dry spells, and everything in between.
If you're thinking of adding another home miner, I keep a simple overview of current Bitaxe, NerdQaxe++, and Zyber models in my TinyChipHub guide.
Find more tools at ProofOfMike.com, or say hi on X: @ProofOfMike.
If you’re dialing in a setup, I also built a power & electricity cost calculator to estimate watts, amps, and monthly cost for home miners.
