Mining Pool Share Calculator
Mining pools combine the hash power of many miners and split block rewards in proportion to each member's contribution. Your slice depends on how much of the pool's total hash rate you supply. This calculator takes your hash rate, the pool's total hash rate, the pool's gross reward over a period, and the pool fee, then returns your share of the pool as a percentage, your gross reward, the fee deducted, and your net payout. Enter both hash rates in the same unit so the ratio is correct.
Pool share formula
Share fraction = your hash rate / pool hash rate
Pool share % = share fraction * 100
Gross reward = pool gross reward * share fraction
Fee deducted = gross reward * (pool fee / 100)
Net payout = gross reward - fee deducted
Both hash rates must use the same unit so the ratio is dimensionless. The model assumes a simple proportional reward split; other schemes such as pay-per-share differ.
Things to know
- Enter your hash rate and the pool total in the same unit (for example both in TH/s).
- Pool fees commonly run 1 to 3 percent and are deducted before payout.
- Reward schemes vary: proportional, pay-per-share, and pay-per-last-N-shares pay differently.
- Short periods show high variance; expected share holds best over many blocks.
- Network difficulty and total pool hash rate change over time, shifting your share.
Mining pool share: frequently asked questions
How is a mining pool reward share calculated?
In a proportional pool, your share equals your hash rate divided by the total pool hash rate. Multiply that fraction by the pool's gross block reward over a period, then subtract the pool fee, to get your net payout. This calculator computes your pool share percentage and your net reward from those inputs.
What is hash rate?
Hash rate is the number of hashing operations your hardware performs per second, measured in units such as megahashes (MH/s), gigahashes (GH/s), or terahashes (TH/s) per second. Enter your hash rate and the pool's total hash rate in the same unit; only their ratio matters for your share.
Why must my units match the pool units?
Pool share is a ratio of your hash rate to the pool's hash rate, so the unit cancels out as long as both numbers use the same unit. If you enter your rate in terahashes and the pool total in gigahashes, the result is wrong by a factor of a thousand. Always convert to a common unit first.
What is the pool fee?
Pools charge a fee, commonly 1 to 3 percent, to cover operating the shared infrastructure and to smooth payouts. The fee is deducted from rewards before they reach members. This calculator subtracts the fee percentage from your gross share to show your net payout.
Does this guarantee my actual payout?
No. Real payouts depend on the pool's reward scheme (proportional, pay-per-share, pay-per-last-N-shares), luck variance in finding blocks, and the period measured. This tool models the simple proportional case and should be treated as an expectation, not a guaranteed amount.
