Crypto Mining Profitability Calculator

1. Enter your miner hashrate and power draw from the manufacturer spec or your meter.
2. Enter your electricity price per kWh and your pool fee.
3. Enter todays network hashrate, the block reward and the coin price from a blockchain explorer.
4. Optionally add the hardware cost to see the payback period.

Bitcoin mining uses specialised computers called ASICs to compete for the right to add the next block. The network pays the winner a block subsidy plus transaction fees. Because blocks arrive roughly every ten minutes, about 144 are found each day, and a miner earns on average a share of them proportional to its share of the total network hashrate.

Profitability is the gap between that expected revenue and the running costs, mostly electricity. Almost every miner joins a pool so rewards arrive as a steady stream instead of rare jackpots, paying a small pool fee in return.

The economics shift constantly. When the price rises, more miners switch on and the network hashrate climbs, shrinking the share of every miner. Every four years the halving cuts the subsidy in half. That is why this calculator asks for current figures rather than using fixed ones.

It works out your share of the network, applies it to the rewards paid per day, and subtracts power costs.

One exahash equals one million terahashes, so your share is s = h / (H x 1,000,000) for hashrate h in TH/s and network H in EH/s. Daily profit is P = s x 144 x R x (1 - f) x p - 24W/1000 x e.

1. Convert the network hashrate to TH/s and divide your hashrate by it.
2. Multiply by 144 blocks and the reward, minus the pool fee, for coins per day.
3. Multiply by the price for revenue, and subtract daily electricity.
4. Divide revenue by daily kWh for the break-even power price, and hardware cost by profit for payback.

These figures are for illustration only. A 200 TH/s miner drawing 3,500 watts runs on power at 0.08 per kWh with a 2 percent pool fee. Assume a network hashrate of 800 EH/s, a reward of 3.125 BTC and a price of 100,000.

The miner earns about 0.00011025 BTC a day, worth about 11.03. It uses 84 kWh, costing 6.72, for a profit of about 4.31 a day or 129 per 30 days. A 4,000 machine would take about 930 days to pay back, and the break-even power price is about 0.13 per kWh.

Move the same miner to power at 0.15 per kWh and it loses about 1.57 a day. Electricity price is often the single factor that decides whether mining works at all.

Large mining farms target power well under 0.05 per kWh, which is why home miners on retail rates often struggle.

Electricity Price

The largest ongoing cost and the main difference between profitable and unprofitable miners.

Hardware Efficiency

Measured in joules per terahash. Newer machines produce more hashes for each watt.

Network Hashrate

As more machines join, your share of each block falls.

Coin Price

Revenue moves one for one with price, while costs do not.

Halvings and Fees

The subsidy halves about every four years; transaction fees can partly offset it.

Before Buying a Miner

Check payback at your power price, and at a lower coin price.

Choosing a Location

Compare home power with a hosting offer.

Deciding Whether to Keep Running

Switch off when revenue falls below electricity cost.

Checking a Cloud Mining Offer

Compare the contract price with what the same hashrate earns.

1. Using a Fixed Network Hashrate

Hashrate usually rises over time, so future earnings are lower than todays estimate.

2. Forgetting Cooling and Overhead

Fans, air conditioning and power supply losses add to the watts on the label.

3. Ignoring the Halving

A payback period that crosses a halving will be far longer.

4. Assuming Todays Price Holds

A price fall hits revenue directly.

5. Leaving Out Tax and Repairs

Mined coins may be taxable and machines need maintenance.

Multiply your share of the network hashrate by 144 daily blocks and the reward, subtract the pool fee, value it at the coin price and subtract daily electricity cost.

It depends mainly on your electricity price and hardware efficiency. Enter current network hashrate and price to check your own setup.

Divide daily revenue by daily kWh used. The calculator shows this break-even power price directly.

Blockchain explorers and mining pool dashboards publish the current network hashrate in EH/s.

After the 2024 halving the subsidy is 3.125 BTC per block. You can add average transaction fees to the reward input.

Divide the hardware cost by daily profit. Remember that rising network hashrate usually lengthens the real payback.

The same share-of-network logic applies to other proof-of-work coins if you adjust blocks per day and the reward.

Pool fees, luck, payout method and stale shares all cause differences from the expected value.
