Bitcoin Mining Electricity Cost Calculator 2026

How to calculate mining electricity cost

The formula is simple: power draw in kW × 24 hours = daily consumption in kWh. Multiplied by your energy rate that gives daily cost. A 2,650 W unit (Antminer S21) uses about 79 kWh per day: 7.90 € at 10 ct/kWh, 15.80 € at 20 ct/kWh, 23.70 € at 30 ct/kWh.

That spread is why identical hardware is profitable at one site and loss-making at another. The calculator does the conversion and puts cost against revenue.

Which electricity price to use

Use the energy rate per kWh from your bill, not an average including the standing charge — that charge applies anyway. For PV self-consumption use the lost feed-in tariff, since that is your real opportunity cost. With heat reuse you may offset the heating cost you save.

Finding break-even

The interesting figure is the electricity price at which daily revenue exactly covers daily cost. Well below it you have buffer for rising difficulty. Just below it your setup is fragile. Above it you burn money every operating day regardless of the Bitcoin price.

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.

New and used miners are covered by statutory warranty under EU law. Used units are tested, cleaned and shipped with a logged hashrate; the exact scope 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.
