How to estimate profitability
Profitability is an estimate, not a guarantee. Recalculate with the exact hashrate and wall power of the selected unit, current network difficulty and reward, coin price, pool fee, uptime, electricity rate, cooling and hosting costs, taxes and other operating costs. Record the input values and calculation time; do not treat a calculator result as a promised return or payback period.
