How does the tool estimate how many coins I will mine?

Your expected share of the network is your hashrate divided by total network hashrate. Network hashrate is derived from difficulty and the coin's block time. Multiplying your share by the coins issued per day gives your expected daily yield before pool fees.

Why do I have to enter difficulty myself?

Network difficulty changes every few minutes to hours and there is no keyless public feed that covers every coin reliably. Entering the current value from a block explorer keeps the estimate honest and chain-agnostic.

What is the relationship between difficulty and network hashrate?

Network hashrate equals difficulty times 2 to the 32nd power, divided by the target block time in seconds. That is the standard formula relating proof-of-work difficulty to the total hashing the network is performing.

Does this account for difficulty rising over time?

No. It is a snapshot at the difficulty and price you enter. Real returns fall as difficulty rises and change with price. Re-run it periodically, and treat the monthly figure as a best-case at today's conditions.

What costs are not included?

Hardware purchase price, cooling, maintenance, downtime, and pool payout minimums are excluded. The tool covers gross reward minus pool fee minus electricity only — the recurring operating margin, not full ROI.

Crypto Mining Profitability Calculator

Mining is only profitable when reward revenue beats the electricity it burns. This calculator takes your hashrate, power draw, and the live network difficulty and price, then works out your expected daily and monthly coins, revenue, electricity cost, and net profit.

How it works

The chain of formulas, all proof-of-work standard:

network hashrate = difficulty × 2^32 / block time (s)
your share       = your hashrate / network hashrate
coins per day    = block reward × (86400 / block time)
your coins/day   = coins per day × your share × (1 − pool fee)
revenue/day      = your coins/day × coin price
power cost/day   = (watts / 1000) × 24 × rate per kWh
net profit/day   = revenue/day − power cost/day

Hashrate units must match: a TH/s ASIC and a difficulty quoted at full scale are reconciled internally so the share ratio is dimensionless.

Example and tips

A 100 TH/s Bitcoin ASIC drawing 3000 W at 0.08 per kWh, against a difficulty near current levels with BTC priced for the day, mines a tiny fraction of a coin daily — the calculator shows whether that fraction’s dollar value clears the roughly 5.76 of daily power it consumes. Watch electricity rate above all: at 0.08 per kWh many rigs are profitable, at 0.20 the same hardware loses money every day. Re-check difficulty before trusting any monthly projection.
