Bitcoin Per Watt Calculator
Bitcoin mining is an energy-intensive operation, and as electricity costs rise, miners are increasingly focused on maximizing efficiency. One of the best metrics for understanding how effectively a mining rig uses electricity is Bitcoin per Watt, which measures how much Bitcoin is earned for each watt of power consumed.
The Bitcoin Per Watt Calculator is a straightforward yet powerful tool that tells you how much BTC you earn per unit of energy. It helps miners make smarter hardware choices, optimize setup configurations, and ultimately improve profitability.
Whether you’re running a small home mining operation or managing a warehouse full of ASICs, understanding how much Bitcoin you earn per watt is key to staying competitive.
Formula
The formula for calculating Bitcoin per watt is:
Bitcoin per Watt = (Hash Rate × BTC per TH/s per Day) ÷ Power Consumption
Where:
- Hash Rate is your miner’s speed, typically in TH/s (terahashes per second)
- BTC per TH/s per Day is how much Bitcoin 1 TH/s earns in 24 hours
- Power Consumption is how many watts your miner uses continuously
This formula gives you a clear picture of mining efficiency in terms of Bitcoin earned per watt of electricity.
How to Use
Using the Bitcoin Per Watt Calculator is very simple. Here’s how:
- Enter your miner’s hash rate in TH/s
- Enter the power consumption in watts
- Enter the current Bitcoin yield per TH/s per day (you can get this from mining profitability websites)
- Click “Calculate”
- The result shows your mining efficiency in BTC per watt per day
You can use this to compare mining rigs, plan upgrades, or evaluate whether your current setup is profitable.
Example
Let’s say you have a miner with these specifications:
- Hash Rate: 100 TH/s
- Power Consumption: 3000 Watts
- BTC per TH/s per Day: 0.000006
Using the formula:
Bitcoin per Watt = (100 × 0.000006) ÷ 3000 = 0.0000002 BTC/W
That means for every watt your miner consumes, it earns 0.0000002 BTC daily. You can multiply this number by your total wattage to estimate daily or monthly earnings.
FAQs
1. What does “Bitcoin per Watt” mean?
It tells you how many bitcoins you generate per unit of electricity consumed — a key measure of mining efficiency.
2. Why is this metric important?
Because electricity is the biggest operational cost in mining. Higher efficiency means more profit.
3. What is a good Bitcoin per Watt value?
It depends on energy cost, but higher values generally indicate better mining profitability.
4. Where do I get BTC per TH/s per Day?
Use mining profitability tracking sites like WhatToMine or NiceHash to find this value.
5. Can I use this calculator for GPU rigs?
Yes, just convert your hash rate to TH/s (1 TH/s = 1,000,000 MH/s) and use your power draw.
6. Does this factor in electricity cost?
No. This calculator only gives BTC per watt. You’ll need a separate calculator to convert BTC to fiat value and compare it with your power cost.
7. Is this useful for choosing mining hardware?
Absolutely. It helps compare ASICs by efficiency rather than just hash rate.
8. Can I calculate monthly or yearly BTC per watt?
Yes. Just multiply the daily BTC/W result by 30 or 365 to get longer-term values.
9. Does this take network difficulty into account?
Indirectly. BTC per TH/s/day reflects current network difficulty, so if it changes, update the input.
10. Can I compare old vs. new miners with this?
Yes. It’s an excellent way to decide if upgrading hardware will improve your ROI.
11. Does this tool require internet?
No. The calculator is browser-based and works offline once loaded.
12. Can I integrate this on my website?
Yes. The HTML and JavaScript are portable and lightweight.
13. How do I improve my BTC per watt?
Use more efficient miners, optimize cooling to reduce power usage, or mine in locations with cheaper electricity.
14. Should I include power supply inefficiency?
Yes, if your PSU is only 90% efficient, actual power draw will be higher. Factor that in for accuracy.
15. What’s a typical value for BTC per watt?
It varies with hardware and market conditions. For modern ASICs, values may range from 0.00000015 to 0.00000025 BTC/W.
16. Is this metric better than profit per kWh?
It’s a complementary metric. BTC/W helps measure efficiency, while profit per kWh accounts for cost.
17. Can I use this for altcoins?
You could adapt it, but you’d need corresponding figures for that coin’s yield per hash rate.
18. What if my mining rig has multiple devices?
Add up total hash rate and total power draw to get a combined BTC per watt value.
19. Does this change with BTC price?
No. BTC per watt is based on actual Bitcoin mined, not its fiat value.
20. Is this useful during bull or bear markets?
Yes. It helps you stay efficient and make better long-term hardware and electricity decisions.
Conclusion
The Bitcoin Per Watt Calculator is a vital tool for anyone in the crypto mining space. It distills complex profitability metrics into one clear value: how much Bitcoin you’re earning per watt of electricity used.
By understanding and tracking this metric, you can compare hardware, tweak your mining setup, and make smarter investment decisions. It helps you reduce energy waste and maximize returns — essential in a world where mining margins are tight and competition is fierce.
Whether you’re just starting or you’re a seasoned miner, this tool brings clarity to your operation. Give it a try, and start optimizing your mining efficiency today!
