Profit depends on your electricity rate, the miner's efficiency (3.31 J/KSol), and the network's current difficulty and coin price, which change daily.
At rated power the 840K bin uses about 66.7 kWh per day. That's about $5.34 a day at $0.08/kWh, or $8.01 a day at $0.12/kWh. The calculator below uses live network data to estimate revenue.

Estimates only. Not financial advice. Revenue = your share of network hashrate × blocks per day × block reward × coin price, minus the pool fee. Real results change with price, difficulty, fees, uptime and hardware wear. Live data comes from CoinGecko, mempool.space, Blockchair and litecoinspace.org.
