Mining profitability remains the most critical metric in cryptocurrency mining.
How can miners evaluate daily earnings from their hardware? What factors influence mining revenue? Numerous tools exist—profit calculators, revenue predictors—but how do they estimate daily mining income?
This guide breaks down mining profit calculations using Bitcoin (BTC) and Ethereum (ETH) as prime examples.
Key Concepts for Mining Profitability
1. Mining Difficulty (Difficulty)
Measures how hard it is to find a valid new block. Higher difficulty means more computational effort is required.
2. Hashrate (Hashrate)
The number of hash computations a miner performs per second (e.g., 1 TH/s = 1 trillion hashes/sec).
3. Block Reward (Block Reward)
The cryptocurrency reward for successfully mining a block (e.g., 6.25 BTC for Bitcoin).
4. 24-Hour Estimated Revenue
Theoretical daily earnings based on hashrate and network difficulty, excluding luck or external factors.

Calculating Bitcoin (BTC) Mining Profit
Formula:
Daily Profit (P) = [ (Block Reward × Hashrate × Seconds per Day) ÷ (Difficulty × 2³²) ]
Example:
- Current BTC Difficulty: 12720005267390.51
- Block Reward: 6.25 BTC
- Hashrate: 1 PH/s (1,000,000 GH/s)
Calculation:
P = (6.25 × 1,000,000 × 86,400) ÷ (12720005267390.51 × 4,294,967,296)
Result: ~0.0197 BTC/day
Calculating Ethereum (ETH) Mining Profit
Formula:
Daily Profit (P) = [ (Block Reward × Hashrate × Seconds per Day) ÷ Difficulty ]
Example:
- Current ETH Difficulty: 2504 TH (2,504,000 GH)
- Block Reward: 2 ETH
- Hashrate: 1 GH/s
Calculation:
P = (2 × 1 × 86,400) ÷ 2,504,000
Result: ~0.069 ETH/day
FAQs
1. Why does mining difficulty change?
Networks adjust difficulty to maintain consistent block times (e.g., Bitcoin targets 10 minutes/block).
2. How do mining pools distribute rewards?
Pools combine hashrate and share rewards proportionally based on contributed work (e.g., PPS, PPLNS models).
3. Can mining be profitable with low hashrate?
Solo mining is unlikely; pools enable steady earnings even for small miners.

Final Notes
- Calculations exclude electricity costs, pool fees, or hardware depreciation.
- Use reliable mining calculators (e.g., WhatToMine) for real-time estimates.
- Adapt formulas for other PoW coins by adjusting block rewards/difficulty metrics.
