Cryptocurrency mining is the process of verifying transactions and adding them to a public ledger (blockchain) using computational power. Miners are rewarded with newly created cryptocurrency and transaction fees. The profitability of mining depends on several key factors:
Key Factors Explained:
Hashrate: This is the speed at which your mining hardware can perform hashing operations. Higher hashrate means more computational power dedicated to mining, potentially leading to higher rewards. It's typically measured in hashes per second (H/s), kilohashes per second (kH/s), megahashes per second (MH/s), gigahashes per second (GH/s), or terahashes per second (TH/s).
Power Consumption: Mining hardware consumes significant electricity. This calculator takes the power consumption in Watts (W) and converts it to kilowatt-hours (kWh) to estimate electricity costs.
Electricity Cost: The price you pay for electricity, usually measured in dollars per kilowatt-hour ($/kWh). This is a major operational expense.
Cryptocurrency Price: The current market value of the cryptocurrency you are mining. A higher price increases the potential revenue from mined coins.
Coin Reward per Block: The number of coins awarded to a miner (or pool) for successfully mining a block. This value often halves over time (known as "halving events") for many cryptocurrencies.
Network Difficulty: This is a measure of how hard it is to find a new block. It adjusts dynamically based on the total hashrate of the network to maintain a consistent block discovery time. Higher difficulty means less chance of finding a block with the same hashrate.
Mining Pool Fee: Most miners join a pool to combine their hashrate and smooth out rewards. Pools charge a small percentage fee for their services.
How the Calculation Works:
The calculator estimates your daily and monthly profit using the following principles:
Hashrate Conversion: Your input hashrate is converted to hashes per second (H/s) to match the difficulty units.
Estimated Coins Mined: Based on your hashrate, the network difficulty, and the block reward, we estimate the number of coins you are likely to mine per day. The formula is approximately:
(Your Hashrate / Network Difficulty) * (Seconds in a Day) * (Block Reward)
Monthly Profit: Estimated Daily Profit multiplied by 30.
Disclaimer: This calculator provides an estimate based on current market conditions and your inputs. Actual profitability can vary due to fluctuations in cryptocurrency prices, network difficulty changes, hardware performance, and electricity rate variations. It does not account for hardware depreciation, initial setup costs, or other potential expenses.

var secondsPerDay = 24 * 60 * 60;
var kWhPerDay = (powerConsumption / 1000) * 24;
var dailyElectricityCost = kWhPerDay * electricityCost;
// Estimate coins mined per day
// The formula estimates the share of the network hashrate your miner contributes.
// (Your Hashrate / Total Network Hashrate) * Total Coins Issued Per Day
// Total Network Hashrate is often indirectly represented by Difficulty.
// A common approximation relating difficulty and hashrate is:
// Block Time = Difficulty * 2^32 / Network Hashrate
// Rearranging, Network Hashrate = Difficulty * 2^32 / Block Time
// Assuming a target block time (e.g., 600 seconds for Bitcoin),
// Network Hashrate = Difficulty * 2^32 / 600
// Coins per Day = (Block Reward / Block Time) * secondsPerDay
// Coins per Day = (Block Reward / 600) * secondsPerDay
// Estimated Coins Per Day = (Your Hashrate / Network Hashrate) * Coins per Day
// Estimated Coins Per Day = (hashrate_Hs / (difficulty * Math.pow(2, 32) / 600)) * (blockReward / 600) * secondsPerDay
// Simplifying:
// Estimated Coins Per Day = (hashrate_Hs * blockReward * secondsPerDay) / (difficulty * Math.pow(2, 32))
var estimatedCoinsPerDay = (hashrate_Hs * blockReward * secondsPerDay) / (difficulty * Math.pow(2, 32));
