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.
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.
The price has gone down for most of the past year, which is a factor that should be strongly considered in your calculations.
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.
Mining can be an effective way to generate passive income. However, there are numerous factors that affect mining profitability, and often times they are out of your control.
Some seem to believe they will be able to quit their nine-to-five job after investing in a few Bitcoin miners – unfortunately, that is not necessarily the case.
How do you know if mining is right for you?
It is important to understand the constantly changing dynamics that play into mining profitability, especially before you invest your hard-earned money. Nevertheless, a proper passive income can be generated if you play your cards right. Let's explore the factors that you need to consider before you buy mining hardware:
The initial investment in efficient mining hardware is probably one of the things keeping you from pulling the trigger, and for good reason. Mining hardware is expensive!
In actuality, the high cost of dedicated mining hardware ASICs (Application Specific Integrated Circuits) is largely to blame for the centralization of Bitcoin mining in China.
In case you were not aware, the vast majority of mining operations are in China, primarily because of cheap electricity (more on that later.) Since ASICs are expensive, many average consumers do not have the capital to invest.
Large mining corporations operate mining farms with thousands of ASICs. The average Joe can't even afford one ASIC, much less thousands of them.
Instead of mining being spread out across the world, the validation process is controlled by fewer people than first anticipated upon Bitcoin's inception.
ASICs' impact on Bitcoin aside, it is important to determine your ROI timeline before investing. Some hardware might not pay itself off at all. The additional factors below are largely responsible for determining your ROI period.
You can use the calculator above to determine your projected earnings based on the ASIC you're using, and your electricity cost.
Every time a block is validated, the person who contributed the necessary computational power is given a block reward in the form of new-minted BTC and transaction fees.
Bitcoin's block time is roughly 10 minutes. Every 10 minutes or so, a block is verified and a block reward is issued to the miner. When Bitcoin was first created, miners received 50 BTC for verifying a block. Every 210,000 blocks – roughly 4 years – the amount of BTC in the block reward halves.
50 BTC per block may seem high, but it is important to consider the price of Bitcoin at that time was much less than it is today. As the Bitcoin block reward continues to halve, the value of Bitcoin is predicted to increase. So far, that trend has remained true.
First, the amount of newly minted BTC (often referred to as coinbase, not to be confused with the Coinbase exchange) halved to 25 BTC, and the current coinbase reward is 12.5 BTC. Eventually, there will be a circulating supply of 21 million BTC and coinbase rewards will cease to exist.
If BTC is no longer minted, mining won't be profitable anymore, right?
Bitcoin transaction fees are issued to miners as an incentive to continue validating the network. By the time 21 million BTC has been minted, transaction volume on the network will have increased significantly and miners' profitability will remain roughly the same.
Of course, block rewards have a direct impact on your mining profitability, as does the value of BTC – since the value of BTC is volatile, block rewards will vary. Additionally, successfully confirming a block is the only way you will generate any revenue whatsoever by mining.
This leads us to our next point:
If you were able to connect the dots, you probably realized that a block reward is worth a whole lot of money. Take a look:
12.5 BTC x current BTC value (approximately $7,200) = $90,500. NOTE: The market is currently bearish – block rewards are always subject to change.
If block rewards are worth so much, why isn't everyone buying ASICs?
Mining Bitcoin is not easy – that's why millions of dollars have been invested to research, develop, prototype and sell specialized mining hardware.
Even if you invest in a specialized mining ASIC which can cost thousands of dollars, your chances of successfully validating a block on your own are slim.
ASICs have caused Bitcoin's mining difficulty to skyrocket. Moreover, you're competing with everyone else on the network to validate a block. Those with more computational power are more likely to validate a block.
As stated previously, companies have set up large-scale mining operations in China with thousands of ASICs running in synchrony. They're more likely to confirm the block than you are on your own.
Nevertheless, there are ways for the little guy to turn a profit. If you want to start mining Bitcoin, consider joining a Bitcoin mining pool. You'll team up with other miners to increase your collective hashing power, thus increasing your chances of validating a block.
If a block is validated by your mining pool, the block reward will be distributed according to the amount of computational power you contributed. For example, if you were responsible for 5% of the hashing power, you'd receive 5% of the block reward, minus pool fees.
Mining pools may not seem appealing at first because you have to divvy up the reward, but they're actually a smart move, as they significantly increase your odds of validating a block. Otherwise, you may end up consuming loads of electricity without actually being rewarded for your work.
Speaking of electricity:
Electricity cost is probably the factor that has the most impact on mining profitability.
After all, Bitcoin's SHA-256 mining algorithm is classified as Proof-of-Work (PoW) because work must be done to validate the network. The 'work' is computational power – therefore electricity is required to validate the network.
Always look at a miner's hashrate/power consumption ratio. Ideally, you want an ASIC that has a high hashrate and low power consumption. Such an ASIC would be efficient and profitable because you'd hopefully validate a block which would be worth more than your electricity costs.
If you don't successfully validate a block, you'll end up spending money on electricity without anything to show for your investment. If you want to maximize your profitability, purchase the most efficient ASIC and mine where electricity is cheap.

In the United States, the average electricity cost is around $0.12 cents per kilowatt-hour. In other countries, electricity cost will vary. Asia's electricity is particularly cheap, which is why China is home to many mining operations.
Bitcoin mining is very competitive. If you are looking to generate passive income by mining Bitcoin, it is possible, but you have to play your cards right.In order to profitably mine, make sure that you:
Now you have the tools to make a more informed decision. Mining is competitive, yet rewarding. If you invest in the proper hardware and combine your hashing power with others', your odds of turning a profit will increase considerably.
