ROI ASIC / VNISH cost in numbers

Dev fee: count it once, then compare the result.

A percentage is easy to read and easy to count twice. We will turn one example fee into a daily amount, show the common double-deduction mistake and connect the number to a full operating comparison.

The example in one numberUSD 0.224example developer share per miner per day, before electricity
Illustrative arithmetic, not a quoted VNISH rate, hardware test or current market return. The example uses 200 TH/s, gross revenue of USD 0.04 per TH/s/day and a hypothetical 2.8% developer fee. Confirm the rate for your chosen build.
01

From a percentage to a daily amount

First calculate gross revenue: 200 TH/s × USD 0.04 per TH/s/day = USD 8 per day. An example 2.8% developer fee represents 8 × 0.028 = USD 0.224. Revenue after that fee is 8 - 0.224 = USD 7.776.

The calculation expresses the developer share in money at the chosen revenue basis. It does not describe an additional invoice. In our example, unchanged inputs for 30 days give USD 6.72 per device or USD 672 for 100 identical devices.

One miner, one day. Electricity has not been deducted yet.

Where the same fee can accidentally be deducted twice

Suppose USD 7.776 is already the revenue after that developer fee. If it is treated as a new gross figure and reduced by 2.8% again, the result becomes USD 7.558272. That second subtraction removes another USD 0.217728 per day from the calculation without representing another fee in the example.

The mistake can also enter through hashrate: if a number already excludes the developer share, applying the fee to that same basis again can reduce it twice. Before entering data, establish which hashrate and revenue figures are before the fee and which are after it.

What to enter in our calculator

Our calculator asks for gross revenue per TH/s per day before Dev Fee. In this example, enter 0.04, the hashrate of 200 and the example fee of 2.8. It applies the fee once. Do not divide the already adjusted USD 7.776 by 200, enter 0.03888 as gross revenue and then subtract the fee again.

If all you have is a pool payment, check what the payment includes. Pool fees, settlement periods, rejected work and other adjustments can prevent a simple reversal. Do not treat an unexplained payout as a clean before-fee figure.

Three fields must describe one basis

Gross revenue: USD 0.04 / TH/s / day
Hashrate: 200 TH/s before the developer share
Dev Fee: 2.8% for this example

Open the calculator and enter these values for the profile you are modelling. Set the second profile to your own comparison inputs.

The developer fee is one part of the operating result

A fee percentage alone cannot decide between two profiles. With 3,000 W and an example tariff of USD 0.08/kWh, daily electricity costs 3 × 24 × 0.08 = USD 5.76. The example profile then leaves 7.776 - 5.76 = USD 2.016 before other costs.

That is the useful comparison: revenue after the fee, less the actual electricity and other costs you choose to include. A profile with a different hashrate, power draw or fee needs its own inputs. Our two-profile calculator keeps those differences visible.

Use the rate from the build you intend to run

Check the applicable developer fee in the firmware and the terms for the selected build. Our example rate is not a substitute for those terms. Keep the source of your revenue estimate and its time period with the calculation.

When you ask us about a fleet, bring the exact model, board, device count, tariff, two profiles and fee basis. We can then discuss the amount left after costs instead of comparing percentages in isolation.

FAQ

Questions about the calculation

Is 2.8% the rate for every VNISH build?

No universal rate is set by this example. Use the applicable rate and terms for the particular build and configuration you choose.

Should I subtract dev fee from a pool payout that already includes it?

Do not subtract the same fee twice. First establish the payout basis. The gross input in our calculator is before developer fee, which the calculator then applies once.

Is the example developer-fee cost the same as total mining cost?

No. Electricity and other operating costs are separate. The daily and monthly fee amounts here assume unchanged hashrate and revenue inputs; they are not forecasts of future payments.

Put the fee beside the power bill

Compare both profiles using one clear gross revenue basis. We show the fee, electricity and operating result separately so you can see what drives the difference.
