About

Cryptocurrency mining requires precise financial planning. Profitability is a function of Hashrate, Power Consumption, and market volatility. Miners must account for Electricity Costs which often determine the viability of an operation. Even a highly efficient rig becomes a liability if the cost per kilowatt-hour exceeds the revenue generated. Hardware depreciation adds another layer of complexity to the Return on Investment (ROI) equation. This tool calculates net profit by factoring in pool fees and energy expenditure alongside network difficulty.

Accuracy relies on current network metrics. The difficulty of mining adjusts dynamically based on the total Network Hashrate. As more miners join, the slice of the block reward shrinks. Conversely, when miners capitulate, yields may increase. This calculator provides estimates based on current snapshots and live market prices to help you determine the break-even timeline for your hardware investment.

Formulas

The core profitability formula subtracts operational costs from gross mining revenue.

{
Revenue = HuserHnet × Rblock × Bday × PcoinCost = W1000 × 24 × Ckwh

Where H is hashrate, Rblock is the block reward, and Bday is blocks per day. The ROI period in days is calculated as:

Frequently Asked Questions

Profitability fluctuates due to three main variables: the coin's market price, the Network Difficulty (which changes as miners join or leave), and the block reward (halving events). Even if your hardware remains constant, the external environment shifts constantly.
The break-even point indicates when you have recovered your initial capital expenditure (CAPEX) on hardware. Until this point is reached, the operation has technically generated a loss on investment. A lower break-even period (e.g., < 200 days) is generally considered less risky.
No. This calculator focuses on operational cash flow and initial cost recovery. Resale value is highly speculative and depends on the future state of the mining market (e.g., if a coin moves to Proof-of-Stake, hardware value may plummet).
This results in negative profitability. In this scenario, it is financially optimal to shut down the mining rig and simply purchase the cryptocurrency directly from the market with the money you would have spent on electricity.
Mining pools charge a fee (usually 1-3%) to smooth out rewards. Solo mining yields erratic returns, whereas pools provide consistent smaller payouts. This fee is deducted from gross revenue before calculating net profit.
