Net mining income generally means mining revenue minus the mining-related costs included in a calculation for the same period. It shows what remains after those costs have been deducted.
The term does not have one standardized formula across miners and mining pools. To understand a reported figure, check its reporting period, currency, and included costs. Income after electricity costs alone answers a different question from profit after operating expenses and hardware depreciation.
How to Calculate Net Mining Income
A practical formula is:
Net mining income = Mining revenue − Included mining costs
For a simple monthly calculation, start with the mining earnings credited by your pool during that month, valued in your chosen currency using a stated conversion method. Then subtract the costs included in your calculation for the same month.
Make sure revenue and costs use the same currency. If earnings are recorded in BTC and expenses in USD, convert them to a common currency before subtracting.
A Simple Example
Suppose a miner records the following hypothetical figures for one month:
| Item | Amount |
|---|---|
| Pool-credited mining earnings, valued in USD after pool fees | $300 |
| Electricity | $180 |
| Maintenance | $20 |
| Income after the stated costs | $100 |
The calculation is:
$300 − $180 − $20 = $100
The miner has $100 remaining after electricity and maintenance. This figure excludes hardware depreciation and any other expenses, so it should not be presented as profit after all costs. Because the pool earnings already reflect pool fees, those fees are not deducted again.
Which Mining Costs Should You Include?
The right cost scope depends on what you want the calculation to show. Common categories include:
- Electricity. Often a major ongoing mining expense, based on consumption and the applicable electricity charges for the period.
- Pool fees. Include these separately only when they have not already been deducted from the revenue input.
- Hosting or facility costs. These may include hosting charges, rent, cooling, and site labor.
- Maintenance and repairs. Expenses tied to keeping mining hardware running.
- Hardware depreciation. Allocates the cost of mining equipment over its useful life.
- Other relevant expenses. Interest, taxes, and allocated overhead may be included in a broader calculation, with their treatment stated clearly.
A calculation limited to electricity and pool fees can help track what remains after those expenses. It does not show full profitability if other relevant costs are excluded.
Check bundled charges carefully. If your hosting bill already includes electricity, cooling, or maintenance, do not subtract those same expenses again. Similarly, avoid treating the full hardware purchase price and depreciation on that purchase as simultaneous expenses in the same profit calculation.
Including depreciation or overhead does not automatically make the result corporate net income. Nor does excluding them make it a formal operating cash-flow measure. Keep the label tied to what the calculation actually includes.
Avoid Double-Counting Pool Fees
Pool-credited earnings may already reflect the pool's fee deduction.
For example, ViaBTC's published PPS+ methodology applies a 4% fee to the block-subsidy component paid through PPS and a 2% fee to the transaction-fee component distributed through PPLNS. Each fee applies to its own component; the rates do not add up to a 6% fee on total earnings. ViaBTC's published formulas already include these deductions. ViaBTC Help Center
If you use the resulting credited earnings as your revenue input, do not subtract the pool fee again. Check the pool's current methodology and the specific earnings figure you are using before adding a separate fee expense.
How Net Mining Income Differs From Other Mining Figures
Block Reward
A Bitcoin block reward consists of the block subsidy plus the transaction fees in the block. The current subsidy is 3.125 BTC following the April 2024 halving. The block reward does not account for mining costs and is not the same as an individual pooled miner's earnings. Bitcoin Developer Guide, Bitcoin halving schedule
Pool-Credited Earnings and Payouts
Pool-credited earnings are the amount allocated to a miner under the pool's payout method, such as PPS+ or PPLNS. They may already be after pool fees, but they do not account for the miner's electricity, hosting, or hardware expenses.
A payout or withdrawal is a transfer of funds and may include earnings from earlier periods. An account balance may also contain accumulated earnings. For a monthly calculation, use earnings attributable to that month rather than assuming the amount withdrawn or the ending balance equals that month's revenue.
Estimated Mining Yield
Estimated mining yield is a projection of the coins a miner may earn under assumptions such as hashrate, network difficulty, and transaction-fee levels. Actual earnings may differ.
Coin price is relevant when converting those projected earnings into fiat revenue or estimating fiat profitability. A change in BTC price alone does not change BTC output for a fixed amount of mining work under otherwise unchanged conditions.
Corporate Net Income
Corporate net income is a company's accounting result across its business activities. It may include non-mining revenue, financing costs, taxes, and gains or losses outside mining operations. A calculation of mining revenue minus selected mining expenses should not be treated as the same figure.
What to State Alongside the Result
To make a net mining income figure understandable, include:
- The reporting period: for example, a particular calendar month.
- The revenue basis: estimated earnings or earnings credited for that period.
- The currency and conversion method: including how BTC earnings were valued if reporting in USD.
- The cost scope: which expenses are included and which are excluded.
- The pool-fee treatment: whether fees are already reflected in credited earnings.
Keep proceeds from selling previously mined coins separate from the period's mining earnings. Those proceeds may reflect coins earned in an earlier period and price changes after they were mined.
For comparisons across periods or operations, use consistent cost categories and valuation methods.
FAQ
Is net mining income the same as a pool payout?
No. A pool payout transfers earnings to you and may include amounts earned in earlier periods. Net mining income subtracts the stated mining costs from revenue for the relevant period.
Does the Bitcoin block reward equal net mining income?
No. The block reward consists of the block subsidy and transaction fees. It does not deduct mining costs or represent each pooled miner's individual earnings.
Can net mining income be negative?
Yes. The result is negative when the included costs exceed mining revenue for the period. With other inputs unchanged, higher network difficulty can reduce expected BTC earnings, while a lower BTC price reduces their fiat value. Higher electricity or hosting costs can also reduce the result.
Why do similar mining setups report different net mining income?
They may have different operating costs or actual earnings. They may also include different expense categories, use different conversion methods, or report different periods. Check these details before comparing the figures.
Should I subtract pool fees when calculating net mining income?
Only if the revenue input has not already had those fees deducted. If you start with earnings credited after pool fees, subtracting the fee again would count the same cost twice.
