Gpu Mining Calculator
Compare GPU mining profitability across ETH, RVN, ERGO, and other PoW coins. Enter values for instant results with step-by-step formulas.
Formula
Daily Coins = (Hashrate x BlockReward x 86400) / (Difficulty x 2^32)
Where Hashrate is in H/s, BlockReward is coins per block, 86400 is seconds per day, Difficulty is the current network difficulty, and 2^32 is used to normalize the difficulty target. Daily profit equals daily coins times coin price minus daily electricity cost.
Worked Examples
Example 1: RTX 3080 Mining Profitability
Problem: An RTX 3080 mines at 100 MH/s, consumes 250W, electricity costs $0.10/kWh, coin price $2,500, difficulty 7.5M, block reward 2, pool fee 1%, GPU cost $500.
Solution: Daily coins = (100M x 2 x 86400) / (7.5M x 2^32) = 0.000536 coins\nAfter 1% fee = 0.000530 coins\nDaily revenue = 0.000530 x $2,500 = $1.33\nDaily electricity = (250W / 1000) x 24h x $0.10 = $0.60\nDaily profit = $1.33 - $0.60 = $0.73\nBreak-even = $500 / $0.73 = 685 days
Result: Daily Profit: $0.73 | Monthly: $21.90 | Break-even: 685 days
Example 2: Low Electricity Cost Scenario
Problem: Same GPU setup but with $0.04/kWh electricity (hydroelectric region).
Solution: Daily revenue = $1.33 (same as above)\nDaily electricity = (250W / 1000) x 24h x $0.04 = $0.24\nDaily profit = $1.33 - $0.24 = $1.09\nMonthly profit = $1.09 x 30 = $32.70\nBreak-even = $500 / $1.09 = 459 days
Result: Daily Profit: $1.09 | Monthly: $32.70 | Break-even: 459 days
Frequently Asked Questions
How does GPU mining profitability calculation work?
GPU mining profitability is calculated by estimating the number of coins your hardware can mine per day based on your hashrate relative to the network difficulty, then converting that to dollar value and subtracting electricity costs. The core formula uses your hashrate, the network difficulty, and the block reward to determine expected daily coin earnings. Higher hashrates earn proportionally more coins, while increasing network difficulty reduces earnings. The final profit equals revenue from mined coins minus electricity costs, pool fees, and hardware depreciation. Network difficulty adjusts regularly based on total network hashrate, so profitability is constantly changing.
What factors most significantly impact GPU mining profitability?
Electricity cost is typically the single largest factor determining mining profitability. Miners in regions with electricity below $0.05 per kWh have a massive advantage over those paying $0.15 or more. The second major factor is GPU efficiency, measured in hashrate per watt. Modern GPUs like the RTX 4090 deliver more hashes per watt than older models. Coin price volatility creates the third major impact, as a 50 percent price drop instantly halves revenue while costs remain fixed. Network difficulty increases as more miners join, reducing individual earnings proportionally. Pool fees typically range from 0.5 to 2 percent and represent a small but constant drain on revenue.
What is network difficulty and how does it affect mining rewards?
Network difficulty is a measure of how hard it is to find a valid block hash that meets the target threshold. It adjusts automatically based on total network hashrate to maintain a consistent block time. When more miners join the network, difficulty increases so blocks are not found too quickly, and when miners leave, difficulty decreases. For individual miners, higher difficulty means fewer coins earned per unit of hashrate. The relationship is inversely proportional: if difficulty doubles while your hashrate stays the same, your expected earnings halve. This self-regulating mechanism ensures that mining profitability tends toward equilibrium where marginal miners operate at or near break-even.
How do I calculate the break-even period for my GPU mining investment?
The break-even period is calculated by dividing the total hardware cost by the daily net profit. Daily net profit equals daily mining revenue minus daily electricity costs. For example, if a GPU costs $500 and generates $2.50 daily profit after electricity, the break-even period is 200 days. However, this simple calculation assumes constant difficulty, coin price, and operating conditions, which never happens in practice. Conservative miners add a 30 to 50 percent buffer to account for difficulty increases and price drops. Consider the residual resale value of GPUs as well, since mining GPUs can often be sold for 40 to 60 percent of their original price after mining becomes unprofitable.
Which coins are most profitable for GPU mining currently?
After Ethereum moved to Proof of Stake in September 2022, GPU miners shifted to alternative Proof of Work coins including Ravencoin using KawPow algorithm, Ergo using Autolykos2, Flux using ZelHash, Ethereum Classic using ETCHash, and Kaspa using kHeavyHash. Profitability varies daily based on each coin price and network difficulty. Miners often use profit-switching software that automatically mines the most profitable coin at any given time and converts to their preferred holding. Multi-algorithm mining pools like NiceHash simplify this process by renting your hashrate to the highest bidder. The most profitable coin to mine is not always the most profitable to hold long-term.
How does cryptocurrency mining work?
Mining uses computing power to solve cryptographic puzzles and validate transactions. Miners earn block rewards and transaction fees. Proof-of-Work mining requires specialized hardware (ASICs or GPUs) and consumes significant electricity.
