How we calculate ASIC mining profit

The short version

A miner’s share of the network’s hashrate is roughly its share of the blocks. So we take that share, multiply it by how many blocks the coin makes in a day and what each one pays, turn it into dollars at today’s price, and take away the electricity.

revenue per day = (miner hashrate ÷ network hashrate) × blocks per day × block reward × coin price

profit per day = revenue − (watts ÷ 1000 × 24 × your price per kWh)

Unless you change it, the electricity price is $0.08 per kWh. On the rankings you can set your own, and every figure is worked out again at your rate.

Where the numbers come from

• Network hashrate. Pulled from mining data providers and each chain’s own explorers or nodes, every 5 to 30 minutes depending on the coin. We use the median of the last six hours, because a single reading can swing a lot.
• Block reward and block time. From the same sources. Where a chain sends part of each block somewhere other than the miner, like Zcash’s development fund or Decred’s stakers, we only count the miner’s part. If the measured block time is way off the chain’s target, we fall back to the target.
• Coin prices. From CoinGecko, refreshed every 10 minutes. A price more than ten times away from its two-week median is thrown out as a bad reading.
• Miner specs. Hashrate and power are the manufacturer’s stock figures. Efficiency is simply watts divided by hashrate, shown in the miner’s own unit: J/TH for Bitcoin miners, J/GH for Scrypt, and so on.
• Prices. For miners we sell, the price is our current price, checked against supplier price lists. Miners we don’t sell have no price, so they have no payback time either.

Coins that pay twice

Scrypt miners earn Litecoin and Dogecoin at the same time, because Dogecoin is merge-mined with Litecoin. We add both together. That’s the only merge-mined pair we count right now. If an algorithm can mine several unrelated coins, we count the main one only.

What the figure leaves out

• Pool fees. We don’t subtract one. Most pools charge somewhere between 0 and 2.5%, so knock that off.
• Transaction fees. Block rewards are mostly the subsidy only, so on busy days real earnings can be a little higher.
• The future. This is what a miner makes today. Difficulty tends to rise, prices move and halvings cut rewards, so tomorrow’s number will be different. Payback time is the price divided by today’s profit, which is a rough guide at best.
• Your setup. Heat, dust, uptime and the odd hashboard failure all shave a bit off. The spec sheet assumes everything runs perfectly.

When a miner shows no profit

A few miners show a dash or $0 instead of a number. That happens when we can’t trust the inputs: a coin with no reliable price, a network whose data we can’t verify, or an algorithm the coin no longer uses. The old Blake256r14 Decred miners are an example: Decred switched to BLAKE3 in 2023, so they can’t earn it any more, and they show their power cost with no income.

The history charts

The trend lines and the profit history on each miner page use one point per day. Each point uses that day’s average network hashrate, block reward, block time and coin price, then takes away electricity at the rate you picked. Because it’s a daily average, today’s point can differ a little from the live figure.
