Before you calculate: solo mining is a lottery

In solo mining, you compete with your own hashrate against the entire Bitcoin network. If you find a block, the full block reward plus transaction fees is yours. If you find none, you get nothing. There is no in-between and no proportional payout like in pool mining.

That is exactly why the calculator below is honest rather than flattering. It shows you two things side by side: the electricity costs that are guaranteed to occur, and the statistical probability of finding a block. So you can see at a glance what you are getting into.

What you set below

  • Miner model and quantity determine your hashrate and power draw.
  • Electricity price and operating hours give you your real running costs.
  • Network hashrate and BTC price are loaded live, so the statistics match today's network.

Read the probability correctly: an expected block every few years does not mean you will definitely have a block after that time. It is a long-term average. In reality, luck or bad luck can deviate considerably from it.

Is solo mining worth it for you?

Calculate your electricity costs and the statistical block probability – honest and without marketing promises.

Electricity cost / month – –
Block probability – per month (24/7 operation)
Expected block every – days (statistical average)
Block reward (current) – –
⚠ Important to understand: Solo mining is a lottery, not a regular income. You either find a whole block (full reward) or nothing. The statistical values above are long-term averages – in real operation, luck or bad luck can deviate from the expected value by several years. Electricity costs, on the other hand, are certain.

So why do people do it anyway?

Because solo mining was never just a cost calculation. A small Bitaxe on your desk draws about as much as a light bulb and gives you the chance to find a whole block all to yourself. It is a lottery ticket that, along the way, makes the network more decentralised and turns you into a real part of Bitcoin.

That is why many people run their devices deliberately as a hobby, a learning project, or a bet on a very unlikely but very large hit. The electricity costs are the price of being in the game. The calculator helps you weigh that price with a clear head.
