Bitcoin Mining Calculator for Home Miners
Solar, Free Nights & Weekends

Home Mining Profitability Calculator — Built for Your Setup, Not a Warehouse

Most mining calculators assume you’re running an industrial operation with a flat power rate. That’s not how it works at home. You’ve got solar hours, free nights from your utility plan, maybe a battery, and a grid rate that only kicks in when everything else runs out. This calculator lets you plug in each one separately so you see what you’d actually earn — not some generic number based on national averages.

It covers over 60 ASIC miners across Bitcoin, Litecoin, Dogecoin, Kaspa, Zcash, Ethereum Classic, and Dash. Pick your hardware from the Miner Catalog, enter your power situation, and it pulls live prices automatically. Track network difficulty and live pricing in the Data Vault. If you’re running aftermarket firmware with a Loki Kit on 120V, there’s a toggle for that too.

Why Mine Instead of Selling Solar Back?

If you’ve got rooftop solar, your utility probably pays you somewhere between $0.02 and $0.06 per kWh for excess energy you send back to the grid. On a good day that’s maybe $1.50 in credits. That credit will never be worth more than $1.50.

Now point that same energy at a miner. At today’s prices you’d earn roughly the same amount — except you’re earning Bitcoin, not a utility credit. Bitcoin goes up. A buyback credit doesn’t. The kWh you mine with today could be worth five times more in a few years. The $0.03 credit from your utility will always be $0.03.

Stack that with a free nights or free weekends plan and your effective electricity cost drops to zero for 16 to 24 hours a day. That’s the whole game. This calculator shows you the math for your exact setup.

Frequently Asked Questions

Is Bitcoin mining still profitable at home in 2026? It comes down to what you pay for electricity. If you’ve got solar, free overnight power, or a rate under $0.08/kWh, the numbers can absolutely work with efficient hardware like the S19K Pro or S21. Run your actual rates through the calculator and see.

Can I run an Antminer S19 on a regular outlet? Not at full power — they need 240V. But with a Loki Kit and aftermarket firmware like LuxOS, VNish, or Braiins OS+ you can run one hash board on a standard 120V outlet at about 40% hashrate and 1,200W. The Electrical Setup guide walks through the wiring.

What is a solar buyback program? Your utility credits your account for excess solar energy you export to the grid. During those hours your electricity is effectively free. This calculator lets you separate those free solar hours from your paid grid rate so you can see exactly what mining earns you versus selling power back.
