Bitcoin Mining Profit Calculator

Why Our Calculator is the Most Accurate

There are many factors that affect your mining profitability. Two of the main factors that influence your profitability are: the Bitcoin price and the total network hash rate.

The Bitcoin network hash rate is growing at a rate of 0.4527678% per day. This means if you buy 50 TH/s of mining hardware your total share of the network will go DOWN every day compared to the total network hash rate.

Our calculator assumes the 0.4527678% daily increase in network hash rate that has been the average daily increase over the past 6 months.

Without factoring in this growth, most Bitcoin mining calculators show results that appear MUCH, MUCH more profitable than reality.

The Bitcoin Price

Even though the network hash rate will cause your share of the network hash power to go down, the Bitcoin price can help make up some of these losses.

The Bitcoin price is rising at a slightly lesser 0.3403% per day over the past year. We suggest you enter a custom Bitcoin price into our calculator based on what you expect the average price to be over the next year.

What our Calculator Assumes

Since our calculator only projects one year out, we assume the block reward to be 12.5. We also use the current Bitcoin price in our calculations, but you can change the Bitcoin price to anything you'd like to get better data.

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.

Welcome to 99Bitcoins’ simple Bitcoin Mining Calculator

This simple Bitcoin mining calculator will allow you to determine how much you can profit from a certain Bitcoin miner. It takes into account all relevant costs such as hardware, electricity and fees. See below for detailed instructions on how to use it.

Instructions on how to use the Bitcoin Mining Calculator:

  1. Enter the hash rate of the Bitcoin miner you’re planning to use
  2. Click on “Calculate mining revenue”
  3. That’s it! (we said it was simple….)

Note: If some values in the Bitcoin mining calculator don’t seem right (exchange rate, block reward, etc.) you can adjust them manually. However normally they are all up to date.

Keep in mind that:

  • Revenue is shown in USD based on the current exchange rate, the exchange rate can (and probably will) change from time to time.
  • Revenue is based on current difficulty to mine Bitcoins. Difficulty can (and probably will) change. From past experience it usually goes up as time goes by.
  • Revenue IS NOT profit. You still have to take into account the cost of your mining hardware and the electricity to run it (and cool it down if needed).

How to Calculate Bitcoin Mining Profitability

Bitcoin mining secures the Bitcoin network. Without miners, Bitcoin could easily be attacked and even shut down. Since Bitcoin miners provide such an important service to the network, they are paid for their services! Each block mined by miners contains a block reward, which is paid out to the miner that successfully mined the block.

While mining today is very competitive, it is possible to run a successful and profitable mining farm. This post will outline the many factors that will determine whether or not your mining operation will be profitable.

Mining Hardware Costs

The upfront costs to pay for mining hardware is usually the largest expense for any new mining farm. Just like good computers cost more money, good mining hardware is expensive. The Antminer S7 is one currently the most efficient miner and costs $629. It only mines about $200 worth of bitcoins per month, meaning just based on hardware costs alone it will take more than three months to get back your money. This does not include electricity costs or equipment costs (more on this below).

When purchasing mining hardware, you will want to look at these metrics: Th/s and W/GH. Th/s, or sometimes Gh/s, measures a miner’s terahashes (Th/s) or gigahashes (Gh/s) per second and is called hash rate. A higher hash rate means a more powerful miner. You can use this simple calculator from Bitcoin Wisdom to determine how much money an amount of hash power will earn per month.

Hardware Efficiency

Hash power is not the end all for determining good miners, though. Miners use massive amounts of electricity. You want a miner that has both a high hash rate and uses the electricity provided efficiently.

W/GH is the metric used to display a miner’s efficiency. The Antminer S7 is also the most efficient miner available on the market, with 0.25 W/GH. Consider that the previous version of the S7, the S5, had an efficiency of just 0.51 W/GH. That means the S5 uses twice as much electricity per hash as the S7.

Buying a miner that has a low W/GH and also has good hash power is the key for any profitable mining operation.

Equipment Costs

Miners generate heat, and also need to be supplied with electricity. Unless you already have the needed parts, you will likely need to purchase cooling fans and power supplies.

Electricity Costs

Electricity costs can make or break any mining operation. A monthly electric bill means monthly costs on top of the upfront cost of the hardware.

China’s cheap electricity is one reason that nearly 60% of the Bitcoin network’s hashing power is located there. In the USA, for example, most mining hardware is run in Washington State, where there is cheap hydroelectricity. Venezuela’s crisis and cheap electricity has also made Bitcoin mining extremely profitable there.

Don’t discount electricity as a cost. It can make or break your mining operation.

Extra Heat and Weather

Creative miners in cold areas can use the heat generated by miners to heat their houses in the winter. If the heat generated by miners will partly replace your normal heating costs, it is one way to save money and improve your chances of profitability.

Miners in cold areas also have an advantage because they may not need to use extra fans to cool the hardware.

Bitcoin Mining Difficulty and Network Hash Power

The Bitcoin mining difficulty makes sure that Bitcoin blocks are mined, on average, every 10 minutes. A higher difficulty is indicative of more hash power joining the network.

As you would expect, more hash power on the network means that existing miners then control a lower percentage of the Bitcoin network hash power.

The image above shows the network hash power over the last 2 years. From September 2015 to February 2016, the network hash rate tripled. That means any miner who added no additional hardware to his farm would earn about 33% less bitcoins.

Hash rate and network difficulty are external factors that should be accounted for. It’s impossible to know difficulty months in advance. However, pay attention to advances in mining technology and efficiency to get a better idea of how the hash rate and difficulty may look down the line.

Bitcoin Price and Block Reward

Bitcoin’s price is volatile and can’t be predicted. You may calculate your profitability with a Bitcoin price of $500, but it won’t be accurate if the price drops to $300 the next day. Be prepared for price movements and understand that the Bitcoin price is a factor that you cannot control.

The Bitcoin block reward is at least one factor that is predictable. Every 4 years, the amount of bitcoins rewarded in each block is cut in half. The reward started at 50 bitcoins per block, and is now 25 bitcoins per block. In July 2016, this reward will fall to just 12.5 bitcoins per block.

Each block reward halving cuts miners’ shares of bitcoins in half. Miners can, however, see similar incomes after a reward halving if the fiat price of Bitcoin doubles.

Bitcoin Mining Calculators

To conclude, use a Bitcoin mining calculator to input your hardware information and electricity costs. This will give you a much better idea on your overall potential to run a profitable mining farm. Remember, however, that some factors like the Bitcoin price and mining difficulty change everyday and can have dramatic effects on profitability.

Repair the Yahoo Search App.

Yahoo Search App from the Google Play Store on my Samsung Galaxy S8+ phone stopped working on May 18, 2018.

I went to the Yahoo Troubleshooting page but the article that said to do a certain 8 steps to fix the problem with Yahoo Services not working and how to fix the problem. Of course they didn't work.

I contacted Samsung thru their Samsung Tutor app on my phone. I gave their Technican access to my phone to see if there was a problem with my phone that stopped the Yahoo Search App from working. He went to Yahoo and I signed in so he could try to fix the Yahoo Search App not working. He also used another phone, installed the app from the Google Play Store to see if the app would do any kind of search thru the app. The Yahoo Search App just wasn't working.

I also had At&t try to help me because I have UVERSE for my internet service. My internet was working perfectly. Their Technical Support team member checked the Yahoo Search App and it wouldn't work for him either.

We can go to www.yahoo.com and search for any topic or website. It's just the Yahoo Search App that won't allow anyone to do web searches at all.

I let Google know that the Yahoo Search App installed from their Google Play Store had completely stopped working on May 18, 2018.

I told them that Yahoo has made sure that their Yahoo members can't contact them about anything.

I noticed that right after I accepted the agreement that said Oath had joined with Verizon I started having the problem with the Yahoo Search App.
No matter what I search for or website thru the Yahoo Search App it says the following after I searched for
www.att.com.

WEBPAGE NOT AVAILABLE

net::ERR_CLEARTEXT_NOT_PERMITTED

I tried to search for things like www.homedepot.com. The same thing happened. It would say WEBPAGE NOT AVAILABLE. The only thing that changed were all the upper and lower case letters, numbers and symbols.
Then it would again say
could not be loaded because:
net::ERR_CLEARTEXT_NOT_PERMITTED

This is the same thing that happened when Samsung and At&t tried to do any kind of searches thru the Yahoo Search App.

Yahoo needs to fix the problem with their app.

Pools / Bitcoin Mining Profitability

With the help of Bitcoin mining calculator you can input parameters such as hash rate, network difficulty, block frequency and get a number of blocks per day as a result. Here is the formula of block/day calculation:
Note:
my_share_rate - a number of shares per second (hash rate / 2^32)
my_share_rate / difficulty - a probability of block generation

  • the income is guaranteed if the mining difficulty is permanent. The more the difficulty is, the less income becomes. Thus, the calculation is only justified till the closest difficulty retarget.
  • the income is guaranteed even if the network hash rate changes. On the other side, increasing hash rate results in faster block generation, thus difficulty retarget is getting closer at the faster pace. Decreasing hash rate, obviously leads to the slower block generation.
