What is this?

The diff change is the rate at which the network difficulty is changing every month. Diff change is used for the estimated future profits graph and break-even analysis. Typically in crypto, network difficulty tends to increase over time, meaning a miner will generate less crypto with the same hardware. Accounting for this changing difficulty is essential to generate long term profitability predictions.

How is this value calculated?

The diff change value is calculated by looking at the current difficulty and comparing it to the 12 hour moving average of the difficulty one month ago. For smaller coins the diff change can sometimes be inaccurate due to a wildly fluctuating difficulty.

Can I disable it?

The diff change factor can be disabled by either manually setting it to 0 or clicking a "Use Diff Change" switch found below the graph and in the break-even analysis section.

What is this?

Hashrate is the only value you need to input to use this calculator, we do the rest of the work for you! Hashrate is the speed which you are mining, and is normally clearly displayed by your mining software or in the specifications for mining hardware. Make sure that you have the correct hashrate suffix selected. For example, if your miner reports 600 GH/s, ensure that GH/s is selected and not TH/s.

What is this?

The Break-Even Analysis feature can help you predict how long it will take to become profitable for a given setup.

How is this calculated?

Time to break-even is calculated by comparing your hardware cost (which you must enter below) to your predicted monthly profits and seeing how long until the initial hardware cost is paid off. The calculator also takes the changing difficulty (diff change) into account. If the network difficulty is increasing quickly, this will greatly increase your break-even time. The diff change can be excluded from the calculation by toggling the "Use Diff Change" switch.

Why is my break-even time 0 or never?

If your break-even time is 0 you have likely forgotten to input your hardware cost below. If it is never, your break-even time has been calculated to be greater than 10 years. This is likely due to a large diff change value which causes your predicted profitability to turn negative in the future. You could try lowering the diff change for a less agressive prediction or disable it altogether.

What is this?

Recurring costs are fixed costs such as rent or internet. This value, along with power costs are subtracted from your revenue to give profit. Higher recurring costs mean lower profits and a longer break-even time.

What is this?

The profitability chart can help you visualize your long term mining projections. The chart can operate in one of three views:

Total Profits

The Total Profits view predicts what your overall profitability will be in the future. This is calculated by taking your current profits and adding them to each following months profits while factoring in the changing difficulty (diff change), the diff change factor can be disabled. This view assumes the price of the coin will stay the same. If you wish to account for a changing price (ie if you think the price will rise in the future), switch to the "Coins Generated" view.

Coins Generated

This view looks at the number of coins you can expect to generate in the future. This view does not account for any expenses, it simply predicts how many coins you will generate with your given hashrate and the diff change value. A high diff change will cause you to generate fewer coins in the future.

Total Costs

This view sums your power and recurring costs. It can be used to predict the total cost to operate your mine over a given period of time.

What is this?

Price Change allows you to factor in the changing price of the currency into your projections. You can use this to generate accurate best-case and worst-case projections for your operation.

Why does Price Change default to 0?

It is impossible to predict what the price of any coin will be in the future, we leave the price predictions up to you.

How does this value factor into the calculations?

It depends on what Selling Profile is set to. For more details, click on the question mark beside the Selling Profile field found directly below Price Change.

What is this?

Selling Profile tells the calculator how to use the Price Change value. Price Change must be set to something other than 0 to have any effect on the profitability projections. Selling Profile has 4 different options:

Sell Coins Monthly

Profitability is calculated as if you were to sell all of your mined coins at the end of each month. Your profits will equal (money earned from selling) - (total expenses + hardware costs)

Sell to Cover Expenses

Only sell enough crypto to cover your monthly expenses. (electricity, rent, etc.) Your profits will equal (unsold crypto * predicted price) - (hardware costs)

Sell a Portion Monthly

Selecting this option will show the Sell Monthly field below, this is where you input what portion of crypto you would like to sell each month. For example, if you plan to sell 25% of your new crypto, enter 25 into the Sell Monthly field. Your profits will equal (money earned from selling) + (unsold crypto * predicted price) - (total expenses + hardware costs)

Never Sell Coins

Select this option if you plan on holding all of your crypto. Your profits will equal (all crypto mined * predicted price) - (total expenses + hardware costs)
