Bitcoin Mining Calculator
Last updated: July 2026 · Network ~780 EH/s · Block reward 3.125 BTC
A Bitcoin miner's profit is simple math: hashrate share × block rewards − electricity. At mid-2026 conditions (~780 EH/s, $100,000 BTC), an Antminer S21 earns ≈ $0.0058 BTC/month; at a hosted rate of $0.072/kWh that leaves roughly $395/month gross → $210/month profit. Calculate any of 16 current ASIC models below.

Investor mode: ROI, payback & the hodl benchmark
Quick calculators overstate returns because they freeze today's difficulty forever. This one simulates month by month: network hashrate compounds (historical average ~3–5%/month), pool fees are deducted, CAPEX is on the books from day one — and the result is benchmarked against simply buying BTC with the same capital. If mining doesn't beat the hodl benchmark, the investment doesn't make sense.
Investor assumptions (difficulty drift, BTC path, pool fee)
Benchmark: mining vs. simply buying BTC
Same $9,800 buys 0.0980 BTC today → worth $9,800 after 24 months (net +$0). Mining nets $-3,925 and accumulates 0.1304 BTC. Buy-and-hold wins under these assumptions.
Break-even BTC price (month 1, opex only): $36,305

How mining profitability works
Revenue = your share of network hashrate × 144 blocks/day × 3.125 BTC block reward × BTC price. Costs = watts × 24h × your all-in kWh rate. The kWh rate is the single most important lever — compare current provider rates in our Hosting Comparison 2026 or check the Hosting Price Index.
Looking for a broader crypto-profit starting point rather than this full Bitcoin model? Use the crypto profit calculator for a focused electricity-cost and ASIC-profit scenario, then return here for the month-by-month investor comparison.
Mining through a marketplace like NiceHash instead of a pool? The calculator above already lets you model real BTC profit per ASIC after fees and your electricity cost — just enter your rate.
Frequently asked questions
How is Bitcoin mining profitability calculated?
Daily revenue is your share of network hashrate multiplied by 144 blocks, the 3.125 BTC block reward and the BTC price. Daily electricity cost is miner power in kW × 24 hours × your all-in rate. The calculator shows the difference as estimated profit before pool fees and future difficulty changes.
What electricity rate should I enter?
Enter the complete rate you actually pay, including any hosting and power charges. This calculator uses $0.065–$0.08/kWh as a hosted-mining comparison range and $0.35/kWh for the German home-rate example. Compare published offers in the hosting comparison before using a provider quote in your calculation.
Does the calculator include pool fees and difficulty changes?
No. The instant calculation is a snapshot using the displayed network assumptions, so it does not guarantee a future result. Deduct your pool fee, commonly 1–2%, and account for potential difficulty growth when evaluating a purchase. Investor mode models changing hashrate and compares the result with buying and holding BTC.
Is hosted mining cheaper than mining at home?
For most German households, competitive hosting is materially cheaper on electricity: this calculator compares $0.065–$0.08/kWh hosting with a $0.35/kWh home scenario. That gap can decide whether an ASIC has a positive operating margin. Review providers independently on our provider reviews before choosing where to run hardware.
