VNISH profitability calculator

More terahashes or fewer watts? We help you compare the result that matters. Enter two operating profiles, your revenue per TH/s and electricity tariff. Our calculator shows the daily operating result, the difference across your fleet and the tariff at which the stronger profile changes. Use it for a stock-versus-VNISH scenario or two VNISH presets on the same SHA-256 hardware.

Compare two profiles ↓

01 / SEE THE DIFFERENCE

Which profile wins at your tariff?

Compare your current profile A with a proposed profile B. Replace the example with your miner’s inputs.

The fields contain an example, not a model benchmark or a live market rate. The calculation assumes 24 operating hours per day and constant inputs.

Profile A your inputs

Profile B your inputs

Enter revenue before Dev Fee. Do not enter a payout after this fee, or it will be deducted twice. Compare one algorithm and one hashrate unit; this calculation uses TH/s.

Only entered costs are included. Capital costs, tax, downtime and changing market conditions are not included automatically.

01

Put both profiles on the same footing

Profile A is your baseline. Profile B is the setup you want to compare. For each, enter hashrate in TH/s, wall power in watts and the applicable developer fee. Use hashrate and power from the same operating state and a comparable observation window. Label an estimate as an estimate. An example in this calculator is an arithmetic scenario, not a performance claim for a particular Antminer.

Enter revenue, electricity and other daily costs in US dollars (USD). The model runs both profiles for 24 hours per day. The fleet count represents identical devices using the selected profile, and the period assumes unchanged inputs. A mixed fleet needs separate comparisons for each hardware group.

02

Start with revenue before the developer fee

Enter gross revenue per TH/s per day before the developer fee. We multiply that value by each profile's hashrate, then apply its fee once. A quoted revenue of 0.05 per TH/s/day and a hashrate of 200 TH/s mean USD 10 of gross daily revenue before fees and costs. These numbers illustrate the formula only.

Do not paste an already fee-adjusted payout into this field and then deduct the same fee again. Check how your source handles pool fees, rejected shares and the revenue period. For a useful comparison, both profiles must use the same revenue basis. This calculator does not fetch a live hashprice, coin price or difficulty forecast.

03

Every result comes from visible arithmetic

Daily gross revenue = hashrate in TH/s × gross revenue per TH/s/day
Daily revenue after developer fee = daily gross revenue × (1 - developer fee / 100)
Daily electricity use in kWh = wall power in W / 1000 × 24
Daily electricity cost = daily electricity use × tariff per kWh
Daily operating result = revenue after developer fee - electricity cost - other daily cost per miner
Fleet result for the period = daily operating result × miner count × days

Every comparison is Profile B minus Profile A. A positive difference favours B on the entered assumptions. A negative difference favours A. The 30-day comparison is a separate fixed 30-day scenario; changing the selected period changes the period result, not that reference.

04

Find the electricity price that changes the decision

A higher-hashrate profile can lead at a low tariff and lose at a higher one. We calculate the crossover tariff by dividing the difference in daily revenue after developer fee by the difference in daily electricity use. At that tariff the two operating results are equal. The result also states which profile leads above or below it.

If both profiles use the same power, there is no single crossover tariff: the higher revenue profile keeps its advantage, or both profiles stay equal. Some comparisons have no crossover at a non-negative tariff. That means one profile stays ahead throughout the tariff range supported here. A crossover compares the two profiles; it is not the electricity price at which either miner individually becomes profitable.

05

Separate operating margin from a payback promise

The result includes the developer fee, entered electricity cost and the other daily cost you supply. The same other daily cost is applied to both profiles, so it changes their absolute results but cancels out of the difference. Cooling, rent, pool fees, repairs, downtime and taxes are included only to the extent that your inputs account for them.

Hardware purchase price and financing are not included. Neither is a future change in hashprice or difficulty. The output is therefore an operating scenario, not a hardware payback date. When one profile has different additional costs or downtime, account for that separately before choosing it. Two negative results can still produce a positive difference: B may lose less than A without making money.

06

Turn the comparison into a useful next step

For a promising scenario, choose the exact Antminer model and control board in our firmware catalogue, then follow its installation route. Keep the two profiles and the measurement window so you can compare the actual result with your starting calculation. For a fleet, begin with one suitable device before extending the decision to comparable hardware.

If you want our help, prepare the model, control board, device count, tariff, two profiles and the issue you want to solve. We can work from a clear question and visible inputs. Leave passwords, wallet secrets and private access details out of the calculation and your first message.

07

Need only J/TH and electricity cost?

Our Energy Cost and J/TH Calculator handles a single profile: power, hashrate, operating hours and tariff. Use it when you need to understand efficiency or calculate an electricity bill. This VNISH profitability calculator adds a second profile, a shared revenue basis, developer fees, fleet size and the decision threshold between the two profiles.

FAQ

VNISH questions, answered

Can I compare stock firmware with VNISH?

Yes. Put the stock measurements in A and your VNISH measurements or explicitly labelled scenario in B. Enter the fee applicable to each profile and keep the hardware, revenue basis and measurement window comparable. The calculator does not assume VNISH wins: the answer follows your inputs.

Does a lower J/TH always mean more profit?

No. A lower J/TH means less energy per unit of hashrate on the measured boundary. The operating result also depends on total hashrate, revenue, electricity tariff, fees and other costs. A more efficient profile can have a lower daily result at one tariff and a higher result at another.

Which developer fee should I enter?

Use the rate shown for the particular firmware and configuration you are comparing. Do not assume one universal VNISH rate. Enter 0 only when a profile actually has no developer fee. The revenue input is before this fee, so it is deducted once.

What does a positive fleet difference mean?

It means B has a higher calculated operating result than A for that device count and period. It does not automatically mean either profile is profitable. Check both individual results and the costs included in the calculation.

Why is there no electricity crossover in my result?

A crossover needs the revenue and power differences to produce a tariff where the results match. With equal power, the revenue advantage stays constant. With some combinations, the equality would occur only at a negative tariff, outside the range modelled here. The calculator identifies which profile stays ahead.

Can I use it for an S19, S21 or T21 fleet?

You can compare two SHA-256 profiles using your own TH/s, watts and revenue inputs. No model-specific overclock or efficiency figures are supplied as measured results. Group different models and cooling types separately. Do not use a Scrypt revenue figure or paste MH/s into a TH/s field.

Does it predict next month's mining revenue?

No. It extends your entered daily assumptions over a chosen number of days, with a separate 30-day comparison. Hashprice, difficulty, uptime and operating conditions can change. Recalculate when the assumptions change.

What should I send ROI ASIC when asking about my fleet?

Send the exact models, control boards, cooling types, number of devices, electricity tariff, measurement period and the two operating profiles. Tell us whether the figures are measured or estimated. Add the calculated difference and the question you want to resolve. Do not include passwords or private keys.
