# Bitcoin Mining Calculator

### Bitcoin Calculator Usage

All you need in order to make the Bitcoin Calculator display a result is to supply the speed of your mining hardware. In this simplest form the calculator will use the current Bitcoin difficulty, block value and USD/BTC rate for the calculations. However, the accuracy of the Bitcoin mining calculator improves the more honest information you supply.

### Interpreting the Bitcoin Calculator Values

The mining results are based on multiple changing factors and are just valid for the given values, thus it's best practice to rely on the Bitcoin mining calculator for a short time frame only. While the Bitcoin difficulty has almost always risen after the expected validity of 14 days and thus might be somewhat forseeable, the Bitcoin exchange rate has proven to highly fluctuate, which might lead to a dramatically different outcome. Because of this dynamics we are only displaying results for at most one month.
