Bitcoin Mining Calculator

The Mining Calculator computes the mining results that you can achieve with a given hardware setup. There are two modes, "novice" and "expert". Expert mode just makes a number of additional input and output fields visible that allow you to calculate the expected returns considering the increase of network hashing power. Click here to read more about how the calculation works.

Bitcoin Blockchain Data

This shows current difficulty (a measure of how hard it is to find a correct hash for a block) and block reward (the amount of BTC that is paid to the finder of a hash.) These values are taken from blockexplorer.com, but any full bitcoin node can provide them. In expert mode, an additional field shows the difficulty increase in percent per day. This is computed from the last 10 difficulty values using an exponential approximation. However, the actual development of difficulty in the future is of course unknown, it might stabilize or even go down, depending on how much hashing power the bitcoin network has.

Mining Hardware Data

The fields in this block let you select the parameters of your mining hardware. Several options can be selected using a drop-down menu, but you can freely edit all fields. For investment, you can also select whether the hardware is bought with USD or BTC. This box also includes a field for the current USD/BTC exchange rate (24 h average.) In expert mode, you can add a pool fee (this reduces the expected outcome, but only a little bit) and the expected time until your hardware is available to you. Especially for ASICs, this may be several months and affects profitability a lot..

Utilization

"Planned time to mine" is the number of months that you intend to run the hardware. Of course this is entirely up to you, but you will see that diminishing returns make it less profitable to run the hardware after some time. In expert mode, you may enter a utilization percentage, for example if you are mining with a machine that has other uses during working hours.

Estimated Mining Results

The initial coins and initial income fields show how many BTC respective USD you will mine given the current difficulty. The break-even and income/planned time fields show after how many days your hardware will have paid for itself, and the total income during the planned time. These numbers take investment and power costs into account, but are calculated using a constant difficulty, which is not very realistic. In expert mode, there is a field "Reduction per Week" showing by how much the income will go down per peek (in percent), and two fields that show break-even and income/planned time considering this reduction. You will see that this differs significantly from the best-case assumption using constant difficulty.
