Will BTC mining still be profitable in 2025? One formula reveals your real earnings

When it comes to mining, many people’s first thought is, “I have no idea how much I can actually earn.” It’s true—manually calculating a bunch of parameters is a hassle. But in reality, there are just a few key data points; once you understand them, mining profits become transparent.

Core Formula for Mining Profits

The core concepts are these:

Hash Rate( - How many hashes your miner can calculate per second, measured in TH/s

Power Consumption - How much electricity your miner uses, measured in watts

Electricity Price - How much you pay per kWh locally—this varies greatly

Difficulty - How fierce the mining competition is across the entire network

Coin Price - The current price of BTC

With these five data points combined, you can calculate your daily, monthly, and annualized ROI.

Calculating with Real Data

Let’s say you bought an Antminer S19 Pro (an older miner with 110 TH/s, now relatively cheap), with a power consumption of 3250 watts and an electricity price of $0.10 per kWh. Plugging this into a calculator:

• Average daily profit: about $18
• Monthly profit: about $540
• Annualized profit after deducting electricity and pool fees: about $6,500

But here’s the problem—if your electricity price doubles to $0.20 per kWh, your profits are immediately cut in half. That’s why it’s crucial to find cheap electricity for mining.

Which Calculation Tools to Use

CryptoCompare - The most professional, very detailed, including pool fee comparisons

WhatToMine - Lets you customize hardware settings and compare multiple coins at once

NiceHash - Focused on GPU mining and hash rate leasing, great for beginners

All these tools work the same way: you enter those five data points, and they automatically calculate everything for you.

Avoid These Pitfalls

1. Don’t forget pool fees - Usually a 1-2% cut
2. Hardware depreciation - Miners lose value every year, make sure to factor this into your ROI
3. Maintenance costs - Cooling, repairs, replacement parts—these costs add up too
4. Coin price volatility - Never calculate based on historical highs; regularly update your parameters

Is Mining Still Worth It in 2025?

Conclusion: If you have access to cheap electricity (<$0.08/kWh), machines like the S19 can still be profitable. But if you’re buying new equipment, the ROI period is much longer, so think carefully. Unlike before, mining is now a professional game.

The key is: Always run real numbers through a calculator first—don’t rely on gut feeling. One quick calculation, and everything is clear.
