Bitcoin Mining Calculator 2026 – Profit & ROI
Free mining calculator: daily profit, ROI, power cost and break-even for Antminer S21, S19k Pro, T21 – with live prices from German stock.
What the calculator covers
The calculator combines hashrate, power draw, your electricity price per kWh, current network difficulty and the Bitcoin price into daily, monthly and yearly figures — gross revenue, electricity cost, net profit and payback time for the given purchase price.
The electricity price matters most: it is the only variable you know for certain and can influence. Price and difficulty are assumptions; your tariff is a fact.
Setting realistic assumptions
- Use today's price, not a hoped-for one
- Plan an annual revenue decline from rising difficulty
- Include pool fees of 1–2 %
- Use actual runtime — a unit running only in sunshine produces proportionally less
- Check the break-even tariff at which your unit turns a loss
From result to decision
If payback lands within a few months the setup is robust, even against rising difficulty. Above two years everything hinges on price, which is a bet rather than a calculation. In between, the deciding factor is how secure your electricity price is over the runtime.
Send us your result and we will check together whether model, power connection and location fit.

Shipping, warehouse and delivery time
Stocked units ship within 2–4 business days from our warehouse in Bavaria, Germany. Because the hardware is already imported and cleared inside the EU, there is no import VAT, no customs paperwork and no waiting for air freight from Asia. Models sourced directly from the factory show their own delivery time on the product page.
We ship insured to Germany, Austria, Switzerland and the rest of the EU. Orders above 1,000 € ship free within Germany, and express shipping is available for stocked units.
Payment, invoice and warranty
You can pay by bank transfer, credit card, PayPal, Apple Pay or cryptocurrency. Every order comes with a proper invoice showing VAT. EU business customers with a valid VAT ID are invoiced at 0 % under the reverse-charge scheme, and we can switch your session to B2B mode with net prices.
Most new miners come with a 6-month warranty. Used units are tested, cleaned and shipped with a logged hashrate; the exact commitment is stated on each product page.
Advice before you buy
We help you check electricity tariff, power connection, cooling, noise and realistic payback before you order — including when the honest answer is that a machine will not pay off at your kWh price. Send us your electricity cost and the planned location and we will run the numbers with you.
