*Net/day is income minus electricity at $0.06 per kWh, a typical hosting rate. Income is an estimate before electricity, based on network conditions in late October 2026; it changes daily with coin price and difficulty. Prices in USD; click a model for full specs and the profit calculator.
Air-cooled S21 and S21 Pro units plug into normal 220–240 V power and cool themselves with fans, which makes them loud. Hydro versions (Hyd) need a water-cooling loop and dry cooler, but run quieter and more efficiently, so they suit hosting farms built for hydro. Immersion versions are designed to sit in a tank of dielectric fluid. If you do not have the cooling set up, choose an air-cooled model or ask us about hosting.
At MinerNexus, Antminer S21 models cost from $819 to $9,184 in USD, depending on version and hashrate. Shipping is quoted after you order.
Before electricity, an Antminer S21 earns roughly $0.035 per TH/s per day at late-October 2026 network conditions. For example the Antminer S21e Hyd – 310 TH/s earns about $11.49 a day before power. Use the calculator on each model for your own electricity price.
At a typical hosting rate of $0.06 per kWh, every S21 model in the table above earns more than its electricity cost, with net income of roughly $1.62–$14.70 a day. At household power prices many models are not profitable, so most owners host them.
They are versions of the same generation with different hashboards: the S21+ and S21 Pro offer more hashrate per watt than the base S21, and the S21 XP has the highest efficiency. Hyd versions are water-cooled versions of each.
You can, but air-cooled S21s are loud and produce a lot of heat, and home electricity often makes them unprofitable. Many buyers ship the miner straight to a hosting provider instead.
