    Bitcoin Hashrate Calculator

    The Bitcoin hashrate calculator converts your mining hardware's hash rate into expected daily Bitcoin earnings. Enter your hashrate in TH/s, GH/s, or KH/s along with your electricity cost to see profitability at current network difficulty.

    GPU Bitcoin Mining Calculator

    This GPU Bitcoin mining calculator calculates profitability for graphics card mining setups. Select your GPU model from the presets below — including RTX 4090, RTX 4080, and other popular cards — or enter your hashrate manually to see daily profit after electricity costs.

    How It Works

    Calculate Mining Profits in 4 Easy Steps

    Our Bitcoin mining calculator uses real network data and your specific inputs to provide accurate profitability estimates

    1

    Select Your Hardware

    Choose from popular ASIC miners like Antminer S21 or enter custom specifications including hash rate and power consumption.

    2

    Enter Operating Costs

    Input your electricity rate, pool fees, and hardware investment to get accurate cost projections for your mining operation.

    3

    Calculate Profitability

    Our algorithm fetches live network difficulty from mempool.space and uses current block reward data to calculate accurate profit estimates.

    4

    Analyze Projections

    View 12-month projections accounting for difficulty increases, break-even analysis, ROI calculations, and efficiency metrics.

    Live Network Data from mempool.space

    Our calculator fetches live network difficulty, hashrate, and next adjustment estimates directly from mempool.space API. It uses the post-2024 halving block reward of 3.125 BTC with adjustable difficulty projections for realistic long-term forecasting.

    Break-Even Electricity Rate Table (2026)

    Your electricity rate determines whether mining is profitable or a money pit. Below is a snapshot of daily profit (or loss) for the Antminer S21 at 200 TH/s and 3,500W, assuming a $84,000 BTC price and current network difficulty. These numbers shift daily with price and difficulty changes.

    Rate ($/kWh) Daily Cost Daily Revenue Daily Profit Verdict
    $0.03 $2.52 $12.80 +$10.28 ✅ Profitable
    $0.05 $4.20 $12.80 +$8.60 ✅ Profitable
    $0.07 $5.88 $12.80 +$6.92 ✅ Profitable
    $0.10 $8.40 $12.80 +$4.40 ✅ Profitable
    $0.12 $10.08 $12.80 +$2.72 ✅ Profitable
    $0.15 $12.60 $12.80 +$0.20 ⚠️ Marginal

    At $0.15/kWh you're barely breaking even. Most profitable operations run at $0.03-$0.07/kWh. If your residential rate is above $0.12, consider hosted mining or simply dollar-cost averaging instead.

    ASIC Hardware Comparison: Which Miner Earns Most?

    Not all miners are created equal. Efficiency (measured in Joules per Terahash, or J/TH) is the single most important spec. A lower J/TH means less electricity wasted per hash computed. Here's how the current generation stacks up.

    Miner TH/s Watts J/TH Price
    Antminer S21 Pro 234 3,510 15.0 $6,500
    Antminer S21 200 3,500 17.5 $5,500
    WhatsMiner M60S 186 3,422 18.4 $5,200
    WhatsMiner M50S++ 150 3,276 21.8 $3,800
    Avalon A1466 150 3,150 21.0 $3,600
    Antminer S19 XP 140 3,010 21.5 $4,200
    Bitaxe Ultra 0.5 15 30.0 $70

    The S21 Pro leads on efficiency at 15 J/TH but costs $6,500. The Bitaxe Ultra is a different beast entirely: an open-source solo miner drawing just 15 watts. You won't profit from it, but it's a way to participate in mining for educational purposes or lottery-style solo mining at near-zero cost.

    How Bitcoin Mining Profitability Is Calculated

    The core formula is straightforward. Your daily BTC earned equals your hashrate divided by the total network hashrate, multiplied by the daily block reward (144 blocks x 3.125 BTC = 450 BTC per day). Then subtract pool fees and electricity costs.

    What makes it tricky is that network difficulty changes every 2,016 blocks (roughly two weeks). If more miners join the network, difficulty rises and your share of the reward shrinks. Over the past year, difficulty has increased about 3-4% per month on average.

    Our calculator pulls live difficulty data from mempool.space and uses your hardware specs to project 12 months of earnings. It accounts for monthly difficulty growth, so the projections are more realistic than flat-rate calculators that ignore rising competition.

    Is Home Mining Worth It vs Just Buying Bitcoin?

    Honest answer: for most people, no. Buying Bitcoin through DCA is simpler, quieter, and often cheaper per BTC acquired. A $5,500 Antminer S21 might mine $4,400 worth of BTC in its first year at $0.08/kWh electricity, meaning you'd accumulate more sats just buying directly.

    Home mining makes sense in specific situations: you have access to very cheap electricity (under $0.05/kWh), you want non-KYC Bitcoin, you can use the heat output (garage heating in winter), or you're genuinely interested in the technical side. The Bitaxe at $70 and 15 watts is perfect for the hobbyist who wants skin in the game without the noise and heat of a full ASIC.

    If your electricity costs are above $0.10/kWh, the math almost never works. Run the numbers above with your actual rate before buying any hardware.

    What the 2024 Halving Did to Mining Profitability

    In April 2024, the block reward dropped from 6.25 to 3.125 BTC. That's a 50% cut to miner revenue overnight. Older machines with efficiency above 30 J/TH became unprofitable almost immediately. The S19 generation survived, but margins got razor-thin at anything above $0.07/kWh.

    What saved many miners was the BTC price rally that followed. Bitcoin moved from around $64,000 at the halving to over $100,000 by late 2024. Higher prices offset the reduced block reward. But that's the gamble: you're betting that price appreciation outpaces the halving's revenue cut.

    The next halving is expected around March 2028, when the reward drops to 1.5625 BTC. If you're buying mining hardware today, your ROI window needs to close before then unless you believe BTC will be significantly higher by that point. Use our halving countdown to track the timeline.

    Sources & Methodology

    How we calculate

    Expected daily BTC reward = (your hashrate ÷ network hashrate) × blocks per day × block subsidy + fees. Daily revenue = expected BTC × live BTC price. Daily electricity cost = power draw (kW) × hours × your $/kWh rate. Net profit subtracts pool fees (default 1%) and electricity. Break-even price solves for the BTC price at which daily revenue equals daily cost. Live network hashrate and difficulty come from mempool.space; live BTC price from CoinGecko.
