Hash rate improves your chance
A miner with more TH/s makes more attempts per second. If all else is equal, doubling hash rate roughly doubles the expected number of block-finding attempts over the same time.
Bitcoin mining probability is the chance that your hash rate finds a valid block before the rest of the network does. Each hash is an independent attempt, so probability grows with more hash rate and more time.
BTCSolo.fyi works as a Bitcoin mining probability calculator by estimating expected hashes per block from current difficulty and then applying probability across common time windows.
How Odds Work
Why hash rate, difficulty, and time matter
Difficulty raises the target work
Bitcoin difficulty represents the expected work needed to find a valid block. Higher difficulty means the same miner has lower odds over 10 minutes, 1 day, or 1 year.
Time compounds probability
Longer time periods give a miner more attempts. The calculator estimates odds over 10 minutes, 1 hour, 1 day, 1 week, 1 month, and 1 year so you can see how probability changes.
Common Time Windows
Odds over 10 minutes through 1 year
10 minutes and 1 hour
These short windows show how unlikely a single block interval can be for most miners. They are useful for understanding immediate Bitcoin block probability.
1 day and 1 week
Daily and weekly odds make it easier to compare hobby ASICs, larger miners, and rented hash rate. Probability remains random even when the expected chance improves.
1 month and 1 year
Monthly and yearly odds show longer-run probability, but they still do not guarantee a block. Difficulty, global hash rate, fees, and BTC price can change during that period.
FAQ
Bitcoin Mining Odds and Probability FAQ
What is a Bitcoin block probability calculator?
It is a tool that estimates the chance of finding at least one block from a given miner hash rate, current network difficulty, and a selected time period.
How do I estimate Bitcoin mining odds by TH/s?
Enter your TH/s value into the calculator. The app converts the hash rate into hashes per second and compares it with expected hashes per Bitcoin block.
Why does the calculator show different odds for each time period?
A miner has more chances as time passes. The probability for 1 year is higher than for 10 minutes, but the result is still probabilistic and not guaranteed.
