Mining Profitability Calculator
Estimate daily and monthly crypto mining profit from hashrate, power consumption, and electricity cost.
How to use this tool
- Enter your mining rig's hashrate in TH/s.
- Enter the power draw in watts and your electricity rate per kWh.
- Find the current daily revenue per TH/s from your mining pool dashboard and enter it.
- Read daily and monthly estimated profit after electricity costs.
Estimate whether your mining setup is profitable before buying hardware. The block reward per TH/s changes with coin price and network difficulty — use current data from a mining pool. Not financial advice.

Formula
Daily revenue ($) = Hashrate (TH/s) × Block reward ($/TH/s/day)
Daily power cost ($) = Power (W) ÷ 1,000 × 24 × Electricity rate ($/kWh)
Daily profit ($) = Daily revenue − Daily power cost
Monthly profit ($) = Daily profit × 30
How it works
This calculator estimates net mining profitability by subtracting daily electricity costs from estimated daily block-reward revenue. Revenue is modelled as a linear function of hashrate using a user-supplied reward-per-TH/s figure, which should be sourced from a mining profitability index for the target coin and current network difficulty.
The model covers only power costs and does not account for pool fees, hardware depreciation, maintenance, cooling, or network difficulty changes, so real profitability will typically be lower than this estimate.
Worked example
Worked example: 100 TH/s miner at $0.08/kWh
- Hashrate = 100 TH/s; block reward = $0.06/TH/s/day; power = 3,200 W; electricity = $0.08/kWh.
- Daily revenue = 100 × $0.06 = $6.00.
- Daily energy = 3,200 ÷ 1,000 × 24 = 76.8 kWh; daily power cost = 76.8 × $0.08 = $6.144.
- Daily profit = $6.00 − $6.144 = −$0.144 (operating at a loss).
- Monthly profit = −$0.144 × 30 = −$4.32.
Daily profit: −$0.144; monthly profit: −$4.32 — the miner loses money at these rates.
Common mistakes to avoid
- Using peak hashrate from the miner spec sheet instead of actual sustained hashrate -- ASICs throttle in warm environments and show real-world hashrates 5-15% below rated specs; using spec hashrate overstates revenue.
- Forgetting that network difficulty adjusts approximately every two weeks for Bitcoin -- if price rises and more miners join, difficulty increases and your share of block rewards decreases; profitability calculations using today's difficulty become stale quickly.
- Ignoring pool fees -- most mining pools charge 1-3% of earned rewards; mining profitability calculators that omit this can overstate actual net earnings by several percent.
Key terms
- Hashrate
- The computational power of a mining machine, measured in terahashes per second (TH/s); higher hashrate means more chances to solve a block.
- Block reward
- The amount of cryptocurrency awarded to a miner per block found; expressed here as a per-TH/s-per-day dollar figure derived from current network conditions.
- Network difficulty
- A protocol parameter that adjusts how hard it is to find a valid block, rising as more miners join and falling as they leave.
- Power Usage Effectiveness (PUE)
- A measure of how efficiently a mining facility uses electricity; the calculator assumes PUE of 1.0 (all power goes directly to miners).
- Break-even electricity rate
- The maximum cost per kWh at which mining is still profitable; calculated by setting daily profit to zero and solving for the electricity rate.
Frequently asked questions
- How do I find the block reward per TH/s per day?
- Check your mining pool's profitability page or a site like WhatToMine. This number changes daily with the coin price and network difficulty, so update it regularly.
- Why is electricity cost so important?
- Electricity is typically the largest operating cost for miners. A small difference in rate (e.g. 0.05 vs 0.10 $/kWh) can be the difference between profit and loss.
