Is higher hashrate always better?

More hashrate earns a bigger share, but it also costs more to run. Efficiency decides how much of the reward is left.

Lower is better. Compare miners on W/TH alongside price and fees.

How big is the network?

It changes constantly. The calculator pulls the current figure when it can.

Understanding Hashrate and W/TH

What hashrate and W/TH mean in Bitcoin mining, how to read them on a miner, and why efficiency drives your running costs.

Hashrate

Hashrate counts how many hash attempts a miner makes each second. The units climb in steps of a thousand: TH/s, PH/s, then EH/s for the whole network.

Your reward share is your TH divided by the network total. 1 EH/s equals 1,000,000 TH/s.

Efficiency in W/TH

W/TH is the power a machine draws for each TH it produces. A machine at 15 W/TH uses less electricity than one at 20 W/TH for the same hashrate.

Specialised ASIC chips are why efficiency has improved so much, and why they replaced GPUs for Bitcoin.

Turning W/TH into a daily cost

Multiply TH by W/TH for watts, then by 24 hours and divide by 1,000 for kWh per day. Multiply by your electricity price to get the daily cost.

Example: 8 TH at 20 W/TH uses 3.84 kWh a day. At $0.05 per kWh that is $0.192 a day, and at 12 W/TH it falls to $0.1152.

Frequently asked questions

Is higher hashrate always better?: More hashrate earns a bigger share, but it also costs more to run. Efficiency decides how much of the reward is left.
What is a good W/TH?: Lower is better. Compare miners on W/TH alongside price and fees.
How big is the network?: It changes constantly. The calculator pulls the current figure when it can.

Try it with your own numbers in the mining calculator. Estimates change with Bitcoin prices, mining difficulty, fees and platform costs. This is education, not financial advice or a promise of returns.
