About CALCMINER.COM

CALCMINER.COM is a free mining payback calculator built for cryptocurrency miners, hobbyists, and investors who want to understand when a rig will start turning a profit. Instead of guessing whether a new ASIC or GPU setup makes sense, you enter your rig’s hashrate, power draw, electricity rate, hardware cost, and pool fee, and the calculator returns daily, weekly, monthly, and yearly net profit alongside an estimated break-even date.

The tool supports six proof-of-work networks out of the box — Bitcoin (SHA-256), Litecoin (Scrypt), Kaspa (kHeavyHash), Ethereum Classic (Etchash), Ravencoin (KawPow), and Monero (RandomX) — with presets for popular hardware such as the Antminer S21 Pro, Whatsminer M60S, and Antminer L7. A live-data refresh pulls current coin price, network hashrate, and block reward so your projections stay close to real network conditions.

A compare mode lets you place two rig configurations side by side against the same network data, which makes it easier to choose between hardware options before you spend. The 24-month payback curve plots cumulative net profit against your upfront capital and marks the break-even point, so the full payback timeline is visible at a glance.

CALCMINER.COM is built and maintained by an independent team focused on transparent, no-nonsense mining math. The figures shown are estimates only — pool luck, difficulty adjustments, hardware resale value, and coin price swings all change the real outcome. Use the results as a planning aid, not as financial advice.
