Bitmain Antminer S21 XP Profitability Calculator

Antminer S21 XP Profitability Overview

The Bitmain Antminer S21 XP profitability calculator allows miners to estimate potential earnings using real-time Bitcoin mining conditions, electricity rates and network difficulty. Delivering up to 270TH/s of SHA-256 mining performance, the Antminer S21 XP is built for miners seeking efficient Bitcoin mining operations. Daily income, monthly revenue and annual profitability can vary depending on Bitcoin market trends, mining competition and operational costs.

Evaluating profitability before deploying mining hardware is essential for maximizing return on investment. The Antminer S21 XP ROI analysis helps miners understand electricity consumption, operating expenses and expected mining rewards. By comparing estimated revenue with ongoing costs, users can assess long-term earning potential and determine whether the Antminer S21 XP fits their mining objectives. Monitoring profitability regularly can also support better decision-making as mining conditions evolve over time.

Antminer S21 XP Specifications That Affect Profitability

The Bitmain Antminer S21 XP runs the SHA-256 algorithm at 270 TH/s while drawing 3645 W from the wall. That works out to an efficiency of 13.5 J/TH, which is the most important number for long term profitability because it tells you how much power each unit of hashrate consumes.

The unit is air cooled and weighs 18.7 kg, so it needs steady airflow and a shelf or rack that can carry its weight. Beyond the hardware itself, your electricity rate and the state of the Bitcoin network decide what the machine actually earns, and both are covered by the live calculator above.

How Electricity Cost Changes Antminer S21 XP Earnings

At 3645 W the machine consumes about 87.5 kWh of electricity per day. At a rate of $0.05 per kWh the S21 XP electricity cost is about $4.38 per day, and at $0.10 per kWh it doubles to about $8.75 per day. Power is the main running expense, so the gap between a cheap rate and an average one often decides whether the miner makes money at all.

Revenue is not fixed. It moves with the Bitcoin price, network difficulty and transaction fees, so the same machine can earn more one week and less the next. Enter your own rate in the Antminer S21 XP profitability calculator above to see current numbers for your situation.

Is the Antminer S21 XP Still Worth Buying?

Bitmain announced the Antminer S21 XP on 18 June 2024 and shipped it from 10 October 2024, which makes it a recent machine by ASIC standards. Its 13.5 J/TH efficiency keeps it competitive against older SHA-256 hardware, since more efficient miners remain profitable at higher electricity rates for longer.

The 90 day history chart on this page shows how daily results have moved with the market, which is a better guide than any single day’s figure. To estimate the Antminer S21 XP ROI, divide the price shown on this page by the live daily profit in the calculator, and remember that the answer shifts as network conditions change.
