Mining Watt Revenue Calculator

Mining watts vs revenue

Daily gross revenue follows revenue = (hash_yours / hash_network) · 144 · block_reward (144 blocks/day at the 10 min target). To get net profit you subtract power · 24h · price_kWh. Take an Antminer S21 running at 200 TH/s: it pulls 3.5 kW around the clock, which over 24 h is 84 kWh. At R$ 0,80/kWh (the Brazilian residential tariff) that puts the power bill at R$ 67/day. If hash price sits near US$ 0,08/TH/day, your gross comes to US$ 16/day, roughly R$ 80, so you keep about R$ 13/day before depreciation and pool fees. Hash price moves every day with the BTC price and difficulty, so check the Luxor Hashrate Index for the current number.

Applications

ROI de ASIC (R$ 30k de S21 ÷ R$ 13/dia de lucro dá uns 6 anos de payback em tarifa residencial, e provavelmente vira prejuízo num halving). Serve também para decidir a hora de entrar ou sair conforme o preço do BTC oscila. E ajuda a modelar a realidade brasileira de custo elétrico: a R$ 0,30/kWh em hidrelétrica subsidiada o lucro fica confortável, enquanto R$ 1,20/kWh em horário de pico vira prejuízo na hora.

FAQ

What is "hash price"? It's a spot index, quoted in USD per TH/s per day, that rolls the BTC price, difficulty and fees into one number. In 2025 it hovered around US$ 0,05-0,12. Multiply it by your TH/s and you have gross daily revenue.

Does halving kill profit? It halves the block subsidy overnight, so margins fall unless the BTC price climbs by the same proportion or transaction fees spike. Ordinals and Runes have briefly pushed fees above the subsidy itself.

What about cooling cost? In tropical climates, budget another 10-20% on top of the miner's wattage for fans and AC. Immersion cooling trims that overhead, though it raises your capex.
