Bitcoin (BTC) Solo Mining Calculator

Estimate how long it takes to solo mine a block of Bitcoin (BTC) with your own hardware. BackPoW combines the live Bitcoin network difficulty with your hashrate to compute the expected block time, the cumulative probability of finding a block over day, month and year, and the expected mining revenue in BTC and USD.

About Bitcoin on SHA-256

Bitcoin uses SHA-256 — non-memory-hard, hardware class: ASIC-dominated.

BackPoW tracks 9 SHA-256 coins. See how SHA-256 solo mining works and which SHA-256 coin is easiest to mine right now →

How Bitcoin solo mining odds are calculated

Because each hash succeeds independently, finding a block is a Poisson process — there is no 'due' block, only an average rate. The mean time between blocks is T = network_hashrate ÷ your_hashrate × block_time, and the realistic chance of at least one block over a period t is P = 1 − e^(−t/T). That is why a longer run raises your odds but never guarantees a block.

Frequently asked questions

How long does it take to solo mine one Bitcoin block?

It depends on your hashrate relative to the Bitcoin network hashrate (940.49 EH/s). Because hashing is memoryless, the time to find a block follows an exponential distribution: on average T = network_hashrate / your_hashrate × block_time. Enter your hashrate in the BackPoW Bitcoin solo calculator to get the exact expected time.

What is the Bitcoin block reward?

The current Bitcoin block reward is 3.14 BTC. BackPoW tracks the 24h block reward and values a discovered block in both BTC and USD using live market prices.

Is solo mining Bitcoin profitable?

Solo mining Bitcoin profitability depends on your hashrate, electricity cost and pool fees versus the block reward value and how often you expect to find a block. The BackPoW calculator shows daily, monthly and yearly gross revenue and net profit so you can decide.

What algorithm does Bitcoin use?

Bitcoin uses the SHA-256 proof-of-work algorithm. You can mine it with any SHA-256-capable ASIC, GPU or CPU listed in the BackPoW hardware database. SHA-256 is a asic-dominated algorithm, which decides what hardware stays competitive.

What are the odds of finding a Bitcoin block?

BackPoW models the cumulative probability of finding at least one block over a day, week, month or year with the Poisson formula P = 1 − e^(−t/T), giving a realistic chance instead of a naive linear estimate.

Is Bitcoin the easiest SHA-256 coin to solo mine?

Not currently. Among the 9 SHA-256 coins tracked on BackPoW, Bitcoin ranks #9 by how little solo hashrate a block takes; the easiest right now is Quai-SHA (QUAI). BackPoW re-ranks them from live difficulty on every update.
