Ethereum Mining Calculator

How it's calculated

Expected daily coins ≈ (your hashrate ÷ network hashrate) × block reward × blocks/day. Daily revenue = that × coin price × (1 − pool fee %). Daily power cost = (watts ÷ 1000) × 24 × $/kWh. Profit = revenue − power cost. The break-even coin price is the level at which daily revenue exactly covers daily power cost — anything above is profit, below is a loss.

For Ethash chains the parameters that matter are block reward (currently 2.56 ETC per block on Ethereum Classic, ~13 second block time → ~6,600 blocks/day) and network hashrate (typically 150-250 TH/s on ETC). The form below pre-fills these for ETC; flex the network hashrate and coin price to model different chains or scenarios.

Worked example

An NVIDIA RTX 4090 mining ETC at 130 MH/s with ~300 W power draw at $0.07/kWh, with ETC at $25 and ETC network hashrate around 180 TH/s: hash share ≈ 0.0000072%. Daily ETC ≈ 0.122 coins, daily revenue ≈ $3.00 after a 1% pool fee. Power cost ≈ $0.50/day. Daily profit ≈ $2.50 — about $75/month per card.

Stack ten of those cards and you're at ~$25/day, ~$750/month gross — meaningful if you've already amortised the hardware, marginal if you bought at peak GPU prices in 2021. Break-even ETC price drops to about $5 at $0.07/kWh — Ethereum Classic is profitable at virtually any modern price under that electricity rate. Flip to $0.15/kWh (typical US residential) and break-even rises to about $11 — still comfortably profitable at current ETC levels, but the margin compresses fast if ETC sells off.

ETH Mining Calculator — what the post-Merge reality means

The Ethereum Merge (15 September 2022) replaced Ethereum's proof-of-work consensus with proof-of-stake, eliminating block rewards for miners and stranding billions of dollars of GPU mining hardware. If you bought a mining rig in 2021 expecting to mine ETH for years, the rig didn't disappear — but its target chain did.

The two practical paths post-Merge are: (1) point your hashrate at Ethereum Classic (ETC), which retained proof-of-work and uses Ethash; (2) sell the rig and recover what you can from the second-hand market. Mining other PoW coins is technically possible but most are saturated by ex-ETH miners, so the per-card profitability has compressed significantly compared to 2021 peaks.

Ethash Mining Calculator: Ethereum Classic and other forks

Ethash is the proof-of-work algorithm Ethereum used pre-Merge. Several chains still run on Ethash today, ETC being by far the largest by hashrate and market cap. Smaller Ethash forks exist (Octa, Etho) but typically have such low network hashrate that profitability calculations become academic.

For ETC specifically, the network hashrate moves with global GPU mining capacity and ETC's price. When ETH was mineable, ETC absorbed a sliver of total ETH-network hashrate; post-Merge that share grew dramatically but coin price didn't keep up, so per-GPU profitability fell. Run the calculator with current network hashrate from a public stats page (2miners, f2pool, or similar) to get an accurate read on current rig economics.

Bitcoin vs Ethereum mining calculator

Bitcoin mining and Ethereum (Ethash) mining are fundamentally different operations. Bitcoin uses purpose-built ASICs that are useless outside Bitcoin; hashrates measure in TH/s; rigs draw kilowatts per unit. Ethash mining used GPUs that retain resale value as gaming hardware; hashrates measure in MH/s; rigs draw a few hundred watts each.

Use this Ethereum mining calculator for GPU-based Ethash mining (ETC primarily). Use the dedicated Bitcoin mining calculator for ASIC-based BTC mining. The math is the same shape — your share of network hashrate × block reward × blocks per day, minus electricity cost — but the unit conventions differ and you can't directly compare a GPU rig's profit to an ASIC's profit without normalising for both.
