Sources & calculation notes
- mempool.space — BTC/USD price ↗
- mempool.space — estimated network hashrate and current difficulty ↗
- mempool.space — mean fees of latest 10 confirmed blocks; subsidy derived from next height ↗
Difficulty is dimensionless; one trillion is 10¹². Hashrate is an estimate. Subsidy excludes transaction fees. With mempool.space, fees are averaged over the latest ten confirmed blocks and subsidy is calculated for the next block height. The timestamp reflects the oldest observation used for freshness.

THE TOOLKIT
A clearer view of mining economics.
Electricity cost
Turn wall power and your electricity tariff into daily, monthly and yearly running costs.
Mining profitability
Estimate Bitcoin revenue, pool fees and operating profit using a sourced network snapshot.
ASIC ROI & payback
Estimate simple hardware payback and annual operating return from your purchase price.
Break-even electricity
Find the highest electricity tariff supported by estimated mining proceeds after pool fees.
ASIC efficiency
Calculate joules per terahash from wall power and hashrate. Lower values mean less energy per hash.
Mining heat output
Convert ASIC electrical load into thermal output for room and facility planning.
Mining cooling
Estimate the thermal load, cooling tons and ideal ventilation airflow for a group of miners.
Mining hosting cost
Account for fleet electricity, management charges, pool fees, setup and hardware investment.
Mixed mining farm
Combine multiple ASIC models, facility overhead and hosting fees to estimate fleet energy, revenue and simple payback.
Mining farm electricity
Budget daily, monthly and yearly electricity for a mixed fleet, including an explicit allowance for facility power.
Mining farm cooling
Estimate simultaneous thermal load and ideal airflow for a mixed fleet, separating ASIC load from additional facility power.
Watts to BTU/hour
Convert a measured electrical heat load from watts to BTU/hour without choosing an ASIC model.
BTU/hour to cooling tons
Convert thermal capacity in BTU/hour to refrigeration tons and equivalent thermal kilowatts.
Hashrate converter
Convert hashing rates between H/s, kH/s, MH/s, GH/s, TH/s, PH/s and EH/s using decimal units.
Mining power requirements
Estimate apparent power and running current from electrical load, voltage and power factor for professional planning.
Mining circuit budget
Compare one ASIC load with a user-supplied current budget and utilization allowance, without prescribing electrical installation.

READ THE ASSUMPTIONS
Useful estimates start with honest inputs.
Wall power, uptime and fees all affect the result. Missing specifications remain unknown. Revenue appears only when a valid network snapshot is available.
LOOK BEYOND ELECTRICITY
Plan for heat and hosting.
Translate electrical load into heat output, estimate ideal airflow, or include setup and management charges in your hosting scenario.
