I've been mining Bitcoin since 2019, and the most common question I get from new and prospective miners is always the same: "Is this machine actually profitable at my electricity rate?"
That question deserves a clear answer — one that reflects real network conditions, real hardware, and the rate you actually pay for power. So I built a calculator that does exactly that. It's free, no account required, and it lives here:
https://orangehorizonbtc.com/bitcoin-mining-breakeven-calculator
🟠 What It Does
The calculator pulls live BTC price and network difficulty from mempool.space on every page load. You drag a slider to set your electricity rate in $/kWh. Every number in the table recalculates instantly — monthly cost, monthly revenue, net profit or loss, breakeven rate, efficiency in J/TH, and solo mining odds per day.
It covers 50+ SHA-256 miners (released in 2022 or later) across two tables. The first is commercial ASICs — Bitmain Antminer S19 through S23 series, MicroBT WhatsMiner M60 through M7DS, Canaan Avalon A16, Bitdeer SealMiner A3 and A4, Auradine Teraflux, and more.
The second table is home and solo lottery miners — Canaan Avalon Q in all three power modes, Avalon Mini 3, Avalon Nano 3S, Bitaxe Gamma and Supra variants, NerdQaxe units, and the Bitaxe Touch. I do not have all the lottery miners listed yet. There are alot of models out there.
🟠 Features Miners Have Asked For
- Currency selector — USD, CAD, EUR, GBP, AUD, and CHF. All values convert automatically.
- Firmware Boost slider — adjustable from 0 to 25%. Models the revenue gain you'd see running third-party firmware like Braiins OS, LuxOS, or Vnish. Compatibility varies by machine, so it's a modeling tool rather than a guarantee — but it gives you a realistic sense of what firmware tuning can do to your margins.
- Search filter — type "S21" to see every S21 variant, "avalon" for Canaan units, "nerd" for NerdQaxe, or any keyword that matches.
- Sort by any column — find the most efficient machines by J/TH, the most profitable at your rate by Net/mo, or the ones with the highest breakeven rate ceiling.
- Solo mining odds — calculated against live network difficulty. Shows you the real per-day probability of hitting a block on each machine.
🟠 Why Breakeven Rate Matters Most
The column most miners should care about is Breakeven. That's the maximum electricity rate a machine can handle before it starts losing money at current network conditions.
If your power rate is above the breakeven number, the machine runs red no matter how long you hold.
If your rate is below it, you're in the green.
Sorting the table by Breakeven shows you which hardware is still viable for home operators and which machines now only make sense in industrial settings with cheap power.
🟠 How To Use It
If you're thinking about starting to mine, or if you already mine and want to check whether your current hardware is still earning at today's hashprice, this is a fast way to get a real answer grounded in today's numbers.
Feedback welcome. If there's a miner missing from the tables or a feature you'd like to see added, let me know in the comments.
