A mining rig can earn coins around the clock, but does it actually turn a profit? To find out, you start with one simple idea: profit is the coins you earn minus what it costs to earn them. The two big costs are electricity and pool fees. This guide shows the formula, walks through a real daily example, and explains how to find your break-even point in plain English.
Mining profit = coin revenue – electricity cost – fees. Coin revenue is the dollar value of the coins your rig mines in a day. Electricity cost is your power draw in kilowatts times hours run times your price per kWh. Fees are mostly the pool fee, a small percentage of rewards. Subtract both costs from revenue to get daily profit. All of these numbers change constantly, so any result is an estimate, not a promise.
The Profit Formula
Mining profitability comes down to one core equation. You earn coins, and you pay to keep the rig running. What is left over is your profit.
The formula is simple to state: profit = coin revenue – electricity cost – fees. Revenue is the dollar value of the coins mined in a period, often a day. The two main costs are the electricity the rig uses and the pool fee taken from your rewards.
It helps to separate two versions of profit. Gross profit is revenue minus electricity only. Net profit also subtracts fees and any other costs, so it is the truer figure.
Each piece is a moving target. Coin prices swing, network difficulty shifts, and power rates differ by region. You can run this math by hand, but a crypto profit calculator updates the inputs for you and returns a clean estimate.
Calculate Your Electricity Cost
Electricity is usually the biggest ongoing cost of mining. The good news is that it is easy to calculate with three numbers you already have.
The formula is: power in kW x hours run x price per kWh. Power is how much your rig draws, measured in kilowatts. One kilowatt equals 1,000 watts, so a 3,000 watt rig is 3 kW.
Here is a worked example. A 3 kW rig running 24 hours uses 3 x 24 = 72 kWh in a day. At a power price of $0.12 per kWh, that is 72 x 0.12 = $8.64 per day. Over a 30 day month, that single rig costs about $259 in electricity alone.
Your rate matters a lot. Mining that profits at $0.08 per kWh can lose money at $0.20 per kWh, with nothing else changed.
Estimate Your Coin Revenue
Coin revenue is the dollar value of what your rig mines. It is harder to pin down than electricity because it rests on three shifting inputs.
- Hash rate: how fast your hardware solves the math, often in megahashes or terahashes per second. More hash rate usually means a larger share of rewards.
- Network difficulty: how hard the network makes it to earn a block. As more miners join, difficulty rises and your share of coins shrinks.
- Coin price: the market value of the coin you mine. The same coins can be worth far more or far less week to week.
Because all three move, revenue is always an estimate. A rise in difficulty or a drop in price can cut your earnings even when your rig runs exactly the same. Note that revenue here means mining rewards, not trading gains.
Most miners join a pool to smooth out earnings. A pool combines many rigs and shares rewards by contribution, so you earn small amounts steadily instead of waiting to find a block alone. In exchange, the pool takes a fee, which is the main fee in the profit formula.
A Worked Daily Example
Let us put the full formula together with one realistic rig. The numbers below are examples only, and real figures change every day.
Take that same 3 kW rig. It costs $8.64 per day in electricity, as shown above. Suppose it earns about $12 per day in coins at current difficulty and price.
Before fees, profit is 12 – 8.64 = $3.36 per day. Now add the pool fee. At a 2 percent pool fee, the rig pays 0.02 x 12 = $0.24 per day. So net profit is 3.36 – 0.24 = about $3.12 per day.
That $3.12 is what you actually keep, before hardware cost. Over a 30 day month, that works out to about $94 in net profit, assuming nothing changes.
A small change in any input can turn that thin margin into a loss. If electricity rose to $0.16 per kWh, daily power cost would jump to 72 x 0.16 = $11.52, leaving almost no profit at all.
Break-Even and Payback
Daily profit tells you if a rig earns more than it costs to run. Break-even tells you how long it takes to earn back the rig itself.
The formula is: hardware cost / daily profit = payback in days. It answers a plain question: how many days of profit does it take to repay the machine?
Use the example above. The rig nets $3.12 per day. If it cost $2,000, payback is 2,000 / 3.12 = about 641 days, or roughly 1.8 years.
That is only a snapshot. If difficulty rises or price falls, daily profit drops and payback stretches out. If the rig stops profiting, the payback clock effectively stops too. Treat break-even as a direction, not a guarantee.

What Can Wipe Out Profit
Mining margins are often thin, so small shifts can erase them fast. These four factors are the most common profit killers.
- Difficulty rising: as more miners compete, the network gets harder and your share of coins falls, cutting revenue.
- Price dropping: if the coin loses value, the same coins mined are worth fewer dollars, so revenue shrinks.
- Electricity getting pricier: a higher rate per kWh raises your biggest cost and can flip a profit into a loss.
- Pool fees and other costs: pool fees, transaction costs to move coins, cooling, and hardware wear all chip away at what you keep.
Two of these deserve a quick note. Moving or spending coins can trigger network charges; our sibling guide on gas fees explained covers those. And if you want a way to earn without running hardware, see staking rewards explained. Both are different topics from mining profit.
Frequently Asked Questions About Mining Profitability
What Is the Basic Mining Profit Formula?
The core formula is profit = coin revenue – electricity cost – fees. Revenue is the dollar value of coins mined in a period. Electricity cost is your power draw times hours run times your rate. Fees are mostly the pool fee. Subtract both costs from revenue to get profit, which is an estimate that changes daily.
How Do I Calculate My Electricity Cost?
Multiply power in kilowatts by hours run by price per kWh. A 3,000 watt rig is 3 kW. Running 24 hours it uses 3 x 24 = 72 kWh. At $0.12 per kWh that is 72 x 0.12 = $8.64 per day. Your local rate changes the result a lot, so use your own price per kWh.
How Is Coin Revenue Estimated?
Revenue depends on three inputs: your hash rate, the current network difficulty, and the coin price. Higher hash rate can earn a larger share of rewards. Rising difficulty lowers your share, and a falling price lowers the dollar value. Because all three shift constantly, any revenue figure is an estimate, not a fixed amount.
How Do I Find My Break-Even Point?
Divide the hardware cost by your daily profit. If a rig nets $3.12 per day and cost $2,000, payback is 2,000 / 3.12 = about 641 days. This assumes profit holds steady, which it rarely does. If difficulty rises or price drops, daily profit falls and payback takes longer.
Why Is My Profit Different From an Online Estimate?
Estimates use a snapshot of difficulty, price, and fees at one moment. Those inputs move all the time, so your real result can differ. Your electricity rate, pool fee, downtime, and hardware efficiency also vary. Treat any calculator output as a rough guide and recheck it often rather than as a locked-in number.
What Costs Do Miners Often Forget?
Beyond electricity and pool fees, miners overlook cooling, transaction costs to move coins, hardware wear, and downtime when rigs stop. Rising network difficulty and falling prices also quietly reduce revenue. Add these to your math so your profit estimate reflects real operating conditions, not just the best case scenario.
Is Crypto Mining Always Profitable?
No. Profit is never guaranteed because difficulty, coin price, and power rates change constantly. A rig that profits today can lose money if costs rise or prices fall. Crypto is volatile and risky. This article is educational only, and you should do your own research before committing money to mining.
