Antminer S21+ (225Th)

As of Mar 13, 2026, considering an electricity cost of 0.045/KWh, the Antminer S21+ (225Th) has been calculated to generate:

• Daily Revenue: $6.978
• Daily Electricity Cost: $4.01
• Daily Net Profit: $2.97

Projected earnings:
• Monthly Net Profit: $89.04
• Yearly Net Profit: $1083.32

No, mining profitability is not guaranteed to stay the same over time. While the current daily profit is shown above, this can fluctuate due to various factors such as:

• Global hashrate changes
• Network difficulty adjustments
• Block rewards
• BTC Exchange rates

Be prepared for potential changes in profitability based on these market dynamics.

The Antminer S21+ (225Th) has a hash rate of 225 TH/S with the SHA-256 algorithm. Note that hashrates are only comparable between miners that use the same algorithm.

Yes, the Antminer S21+ (225Th) consumes 3713 W per hour. You can adjust your local electricity price in the header preferences to see profitability calculations based on your actual electricity cost.

Electricity expenses are a significant factor in mining profitability. With the power consumption of 3713 W, your daily electricity cost is 4.01. Higher electricity rates can reduce or even eliminate profits, which is why assessing local energy costs is crucial when determining if mining is viable.

With higher electricity costs, investing in a highly efficient miner like this one (efficiency: 16.5 J/Th) becomes even more important.

The lifespan of mining hardware depends on several key factors:

• Usage intensity
• Environmental conditions (temperature, humidity: 10 - 90 %)
• Maintenance quality
• Cooling system (Air)

Proper maintenance and ideal operating conditions can significantly extend hardware longevity.
