A crypto mining calculator is only as good as the assumptions you feed it, and the biggest one is revenue per unit of hash rate β a number that changes every single day as network difficulty rises, coin prices swing, and the overall hash rate racing for the same block reward grows or shrinks. This tool doesn't pretend to fetch that number live and hand you false confidence; instead it puts the daily revenue per TH/s field front and center as something you should actively look up and edit, then does the honest arithmetic around it: subtract your real electricity cost, subtract the pool's cut, and show you what's actually left, plus how long your hardware takes to pay for itself at that rate.
Arb Digital built this as part of a free suite of crypto and finance tools because most mining-profitability calculators online oversell the "set it and forget it" idea. Mining is closer to running a small energy-arbitrage business than a passive investment, and this calculator is built to make that plain. If you're weighing mining against other crypto strategies, our crypto staking calculator and crypto profit calculator are useful side-by-side comparisons.
What This Crypto Mining Calculator Does
You enter your hash rate, your rig's power draw in watts, your actual electricity rate, the pool fee you're charged, an estimate of daily revenue per terahash, and what the hardware cost you. The calculator converts your power draw into a daily electricity cost, applies the pool fee to your gross mining revenue, and nets the two against each other to produce a daily profit figure. From there it projects a monthly and annual profit at that same rate, and calculates how many months of that profit it takes to recover your hardware cost. None of this assumes difficulty or price stays constant over that period β it's a snapshot at the assumptions you entered, meant to be rerun regularly as those inputs change.
How to Use It
- Enter your hash rate in TH/s. This is listed on your mining hardware's spec sheet or your pool dashboard.
- Enter your rig's power consumption in watts. Use the actual wall-draw figure, not just the chip's rated efficiency, since power supplies and cooling add overhead.
- Enter your real electricity rate. Check your utility bill's marginal rate per kWh, not an averaged bill total, since mining runs continuously and pushes you into your highest-cost tier.
- Enter your pool fee. Most mining pools charge 1%β3% of your gross revenue for pooling your hash rate with others.
- Enter today's estimated daily revenue per TH/s. Look this up on a current mining-profitability chart for your coin β this number changes daily and is the single biggest driver of your result.
- Enter your hardware cost so the calculator can estimate your break-even timeline.
- Click Calculate and revisit this regularly β a mining calculation from three months ago is not a reliable guide to today.
The Formula / How It's Calculated
Gross daily revenue is your hash rate multiplied by the revenue-per-TH/s figure: gross revenue = hash rate Γ revenue per TH/s. The pool takes its cut from that: net mining revenue = gross revenue Γ (1 β pool fee / 100). Your daily electricity cost converts watts to kilowatt-hours run continuously for 24 hours, multiplied by your rate: daily power cost = (watts Γ· 1000) Γ 24 Γ cost per kWh. Daily profit is simply net mining revenue β daily power cost. Monthly profit multiplies that by roughly 30, and annual profit multiplies daily profit by 365. Break-even months divide your hardware cost by your projected monthly profit. The U.S. Financial Industry Regulatory Authority (FINRA) publishes general investor alerts on cryptocurrency mining and investment risk at finra.org, which is a useful, neutral read before committing real capital to mining hardware.
Electricity Price Is the Whole Game
Ask any serious mining operator what determines whether a rig is profitable and the answer is almost always electricity, not hash rate. Two identical rigs running the same algorithm at the same difficulty can have completely different outcomes purely based on their power bill: a rig on $0.06/kWh industrial power can be solidly profitable while the identical rig on $0.18/kWh residential power loses money every single day. This is why large-scale mining operations chase cheap power β stranded hydro, flared natural gas, off-peak nuclear contracts β rather than chasing hash rate alone. If you're mining at home, run this calculator with your actual marginal electricity rate (check your utility bill, since many residential plans have tiered pricing that gets more expensive the more you use), and factor in cooling costs during hot months, since air conditioning to offset rig heat is a real, often-overlooked expense.
Rising Network Difficulty Erodes Revenue Continuously
Mining difficulty on most proof-of-work networks adjusts periodically to keep block production roughly constant regardless of how much total hash power is competing. When more miners join the network β chasing the same profitability you are β difficulty rises, and your fixed hash rate earns a shrinking share of the block rewards over time, even if the coin's price doesn't move at all. This is a structural, ongoing headwind for every miner: your hardware's raw hash rate doesn't decay, but its *share* of global hash rate typically does, unless you're one of the ones adding more machines. This is precisely why the "daily revenue per TH/s" field in this calculator needs to be a current, actively-checked number rather than something you set once and trust for the next year. A profitability estimate from six or twelve months ago is very often stale by a wide margin.
Hardware Depreciates Fast β Model Mining As a Business
Mining ASICs and GPUs are specialized equipment with a real, often short useful life. Chip efficiency improves generation over generation, so last year's top hardware can become uncompetitive well before it physically breaks β a purely economic obsolescence on top of ordinary wear. Hardware resale values for mining equipment tend to fall quickly once a newer, more efficient model ships, which means the break-even timeline this calculator produces is optimistic if you assume you can recover residual value by reselling later. Treat a mining rig the way a small business treats a piece of production equipment: track depreciation, budget for repairs and eventual replacement, and don't assume today's profitability curve holds for the machine's entire physical lifespan. Investopedia's overview of cryptocurrency mining economics at Investopedia is a solid plain-English explainer of these dynamics if you want more background before buying hardware.
Cloud Mining and Contract Offers: Extra Scrutiny Required
This calculator assumes you own physical hardware, but a lot of the mining offers marketed to beginners are actually cloud-mining contracts β you pay upfront for a claimed share of someone else's hosted hash rate rather than buying your own rig. Some cloud-mining operations are legitimate businesses; a meaningful number historically have not been, and the space has a well-documented history of unsustainable or outright fraudulent contracts that promised fixed daily payouts regardless of actual mining economics. If you're evaluating a cloud-mining contract instead of physical hardware, run its advertised numbers through this same calculator using its stated hash rate, its disclosed fee structure, and a realistic revenue-per-TH/s figure β if the contract's advertised payout is meaningfully higher than what the honest math here produces, treat that gap as a red flag rather than a bonus. FINRA and the SEC have both issued specific investor alerts about cloud-mining and crypto-mining investment scams over the years, and it's worth reading one before wiring money to any hosted-mining offer you can't independently verify.
Building a Simple Monitoring Habit
Because the inputs that matter most here β coin price, network difficulty, and your effective revenue per TH/s β move continuously, a one-time mining calculation isn't a plan, it's a snapshot. Miners who treat this seriously tend to check current profitability weekly at minimum, track their actual electricity cost against their utility's billing cycle rather than an estimate, and keep a running log of hardware age and any repair costs so the true break-even timeline stays visible rather than optimistic. If your calculated daily profit turns negative for an extended stretch, that's useful information, not just bad news β it's the signal that tells you whether to hold hardware idle, sell it, or redirect it toward a different, currently more profitable coin if your equipment supports switching algorithms.

Talk to Arb Digital All Free ToolsCommon Mistakes to Avoid
- Using an average electric bill instead of your marginal rate. Continuous mining load often pushes you into your most expensive pricing tier.
- Ignoring cooling costs. Air conditioning to offset rig heat can materially cut into summer profitability.
- Treating an old profitability snapshot as current. Difficulty and coin price both move fast; refresh your revenue-per-TH/s figure often.
- Assuming hardware holds its resale value. Mining equipment depreciates quickly as more efficient models are released.
- Forgetting pool fees and payout minimums. Small percentages add up over months of continuous operation.
- Not budgeting for downtime and repairs. Rigs run hot and continuously; failures are a real, recurring cost of doing business.

Frequently Asked Questions
It depends almost entirely on your electricity rate and current network difficulty. At high residential electricity prices, many mining setups run at a loss; at low industrial rates, the math can look much better.
That figure depends on live coin price and network difficulty, both of which change constantly. Look up a current mining-profitability estimate for your specific coin and enter it here rather than trusting a fixed built-in number.
Use your marginal rate per kWh from your actual utility bill, not an average β continuous mining load can push you into a higher-priced usage tier on tiered residential plans.
Physically, often several years, but they can become economically obsolete much sooner as newer, more efficient hardware lowers the profitability of older machines.
Not always, but it trends upward over time as more hash power joins a network, which generally shrinks each miner's share of block rewards unless price gains offset it.
Pool fees are typically fixed by the pool operator, though rates vary between pools, so comparing a few options for your coin and hash rate can be worth the time.
