What if conditions change?
Each row changes one assumption from your inputs. Other inputs stay fixed.
| Scenario | Remainder |
|---|---|
| Your inputs | -$2.94 |
| BTC price −20% | -$4.41 |
| Difficulty +25% | -$4.41 |
| Electricity +$0.05/kWh | -$6.36 |
Before hardware, separate cooling, repairs, hosting, financing and taxes. Expected output is a long-run average, not a guaranteed payout.
Your assumptions
Start with the example. Every field is editable; results update as you type.
Find a dated difficulty on mempool.space. See how to choose hardware inputs and what the block subsidy means. Inputs stay on your device.
Read the result, then challenge it.
The Bitcoin mining profitability guide works through this same example, the power-price threshold and what the model leaves out. Use the energy-cost guide to check which charges belong in your tariff. For KAS equipment, the Kaspa mining cost case explains the separate device and payout assumptions; this calculator models Bitcoin.
The calculation
Daily BTC = hashrate in hashes/second × 86,400 × uptime fraction ÷ expected hashes per block × reward. Expected hashes per block = difficulty × 248 ÷ 65,535. Revenue minus pool fee minus electricity gives the operating remainder.
Reward is whatever you enter: subsidy alone, or subsidy plus an explicit average fee assumption. See the Bitcoin developer references for difficulty targets, block rewards and pool mining. Sources checked 18 September 2026.
Mining calculator questions
Is the result my mining profit?
It is an expected operating remainder after pool fees and machine electricity. Hardware, separate cooling, repairs, hosting, financing and taxes are excluded. A positive number does not establish that buying a miner will pay back.
Does this calculator use live Bitcoin data?
No. Every starting value is an illustrative assumption. Enter a dated network difficulty, your chosen BTC price and measured machine inputs. The calculator runs locally and sends none of your inputs to a provider.
What does the electricity break-even rate mean?
Revenue after the pool fee divided by energy use gives the electricity rate at which the operating remainder is zero. With the example inputs it is about $0.107 per kWh, before other costs. With zero uptime or zero power, this rate is undefined.
Can I use this for Kaspa or Zcash mining?
No. The expected-work model uses Bitcoin difficulty. Kaspa and Zcash have different mining rules; changing the coin price does not make this calculator valid for them.
