## Crypto Mining Profitability Calculator — By Hardware Class & Electricity Rate

Model Bitcoin mining profit from your exact hashrate, power draw, and electricity rate against current network difficulty and price — then find your break-even electricity rate, the single number that decides whether a given ASIC is worth running at your local power cost.

- Break-even electricity rate, not just a daily profit snapshot
- Built for comparing hardware classes side by side, not one generic miner
- Shows exactly how thin 2026 margins are at real-world power prices

## Quick Answer — Is Bitcoin Mining Profitable Right Now?

Daily profit is **(your share of global hashrate × block reward × 144 blocks/day × BTC price × (1 − pool fee)) − (power draw in kW × 24 hours × electricity rate)**. Everything else in mining economics is a variation on that one equation.

**Quick reference (Antminer S21, 200 TH/s, 3,500W, 17.5 J/TH, network at 915 EH/s, BTC at $64,103, 3.125 BTC block reward, 1% pool fee):**

• At $0.08/kWh (the roughly break-even 2026 rate for this hardware) → **-$0.48/day** (a loss)

• At $0.05/kWh → **+$2.04/day** (~$745/year)

• At $0.03/kWh → **+$3.60/day** (~$1,315/year)

The break-even electricity rate for this specific hardware and network condition works out to about **$0.0743/kWh** — below that rate, the S21 is profitable; above it, it loses money every single day it runs. That single number is the most useful output of this entire calculator, because it turns a wall of daily-profit noise into one comparison point against your actual power bill.

## How to Use This Calculator

Enter your miner's hashrate (TH/s) and power draw (watts) — both are on the manufacturer spec sheet — along with your electricity rate, pool fee (1% is typical), current BTC price, current network hashrate (in EH/s), the current block reward (3.125 BTC as of 2026, unchanged since the 2024 halving), and optionally your hardware purchase cost to see a payback estimate.

**Worked example (Antminer S21 at a moderate $0.08/kWh):** 200 TH/s hashrate, 3,500W power, 915 EH/s network hashrate (= 915,000,000 TH/s), 3.125 BTC block reward, 1% pool fee, $64,103 BTC price. Your share of the network = 200 ÷ 915,000,000 = 0.0000002186. Daily gross BTC = 0.0000002186 × 3.125 × 144 = 0.00009836 BTC, or 0.00009738 BTC after the 1% pool fee — worth **$6.24/day** in revenue. Daily power = 3.5 kW × 24 hr = 84 kWh, costing 84 × $0.08 = **$6.72/day**. Net result: **-$0.48/day**, a loss — this specific hardware is not profitable at this specific rate.

**Same hardware, cheaper power:** drop the rate to $0.05/kWh and nothing else changes. Daily power cost falls to 84 × $0.05 = $4.20, flipping the result to **+$2.04/day profit** (~$61/month, ~$745/year) — with a hardware payback of roughly 2,204 days (about 6 years) at $4,500 hardware cost, which is a genuinely long payback and worth stating plainly rather than glossing over.

## The Formula This Calculator Uses

**Your share of network hashrate** = Your hashrate (TH/s) ÷ (Network hashrate in EH/s × 1,000,000).

**Daily gross BTC** = Your share × Block reward × 144 (the average number of blocks Bitcoin's difficulty targets per day, at a 10-minute average block time).

**Daily net BTC** = Daily gross BTC × (1 − Pool fee %).

**Daily revenue (USD)** = Daily net BTC × BTC price.

**Daily power cost** = (Power watts ÷ 1000) × 24 hours × Electricity rate.

**Daily profit** = Daily revenue − Daily power cost.

**Break-even electricity rate** = Daily revenue ÷ Daily power in kWh — the exact rate at which profit hits zero, holding everything else constant.

**Efficiency (J/TH)** = Power watts ÷ Hashrate TH/s — lower is better, and it's the number that actually differentiates one ASIC generation from the next.

## Why Hardware Class Matters More Than People Assume

Most mining calculators let you plug in one hashrate and one power figure and stop there. But the gap between ASIC generations is exactly where profitability actually lives in 2026's thin-margin environment, because efficiency (joules per terahash) determines your power cost per unit of hashrate, independent of everything else.

**Comparing three current-generation Bitmain miners at the same $0.08/kWh rate:** the Antminer S21 (200 TH/s, 3,500W, 17.5 J/TH) loses about $0.48/day. The Antminer S21 Pro (234 TH/s, 3,510W, 15 J/TH) turns a small profit of about $0.56/day. The Antminer S21 XP (270 TH/s, 3,645W, 13.5 J/TH) does noticeably better at about $1.43/day. Three miners, the same electricity rate, and the difference between a loss and a real (if still modest) profit comes entirely from efficiency — an 18% efficiency gain from the S21 to the XP roughly triples daily profit at this rate.

This is the practical, defensible angle a generic mining calculator misses: the question isn't 'is Bitcoin mining profitable,' it's 'is *this specific hardware* profitable *at my specific electricity rate*,' and the answer changes meaningfully between ASIC generations even when every other input stays fixed.

## The Break-Even Electricity Rate Is the Number That Actually Matters

Daily profit in dollars is intuitive but fragile — it moves every time BTC price or network difficulty shifts, even if your hardware and power rate never change. The break-even electricity rate strips that volatility out and answers a more stable question: given today's network conditions, what's the maximum I could pay per kWh and still not lose money?

For the S21 at current 2026 network conditions, that number is about **$0.0743/kWh**. If your actual rate is below that, you have a margin of safety that shrinks as difficulty rises or price falls; if it's above that, no amount of optimization elsewhere fixes the math — you need cheaper power, more efficient hardware, or both.

This is also the right lens for evaluating a hosting or colocation deal: a facility quoting $0.06/kWh for an S21 offers real margin versus the $0.0743 break-even, while $0.09/kWh guarantees a loss on this hardware regardless of BTC price movement in your favor.

## What This Calculator Doesn't Account For

This model holds network hashrate, difficulty, and BTC price constant for the calculation, but all three move constantly in reality — network hashrate has swung meaningfully within any given year, and difficulty adjusts roughly every two weeks to track it. A profitable setup today can turn unprofitable within weeks purely from difficulty rising as more hashrate joins the network, with no change to your own hardware or rate.

It also excludes hardware depreciation and failure risk (ASICs typically have a useful life of 3-5 years before efficiency losses or failure make replacement worthwhile), cooling costs beyond the miner's own power draw (relevant for larger operations), and any facility, hosting, or maintenance fees beyond the electricity rate itself.

## Frequently asked questions

### Is Bitcoin mining still profitable in 2026?

It depends heavily on your electricity rate and hardware efficiency. Current-generation ASICs like the Antminer S21 break even around $0.07-0.075/kWh at 2026 network conditions — below that, mining can be profitable; above it, it's a reliable loss regardless of BTC price optimism.

### What is the break-even electricity rate, and why does it matter more than daily profit?

It's the exact per-kWh rate at which profit hits zero for your specific hardware and current network conditions. Unlike a daily dollar figure, it isolates the one variable — your power cost — that you actually control, making it the right number for comparing hosting deals or deciding whether to keep mining.

### Why does a small efficiency improvement (like 17.5 to 15 J/TH) matter so much?

Because efficiency directly sets your power cost per unit of hashrate, and margins in 2026 are thin enough that an 18% efficiency gain (like the S21 to the S21 XP) can be the difference between a daily loss and a real profit at the same electricity rate.

### Why is my payback period so long even when I'm profitable?

Thin per-day margins mean hardware payback can stretch to years even in profitable scenarios, especially at electricity rates only modestly below the break-even point. A larger gap between your rate and the break-even rate shortens payback substantially — payback is highly sensitive to that spread.

### Does this calculator account for network difficulty rising over time?

No — it uses the network hashrate and block reward you enter as fixed for the calculation. In reality, network hashrate and difficulty change roughly every two weeks, which can turn a profitable setup unprofitable without any change to your own hardware or rate.

### What's a typical pool fee?

Most mining pools charge 0-2%, with 1% being a common default. Solo mining avoids the fee entirely but makes finding a block far less predictable for smaller operations.

### How is this different from a generic 'enter your hashrate' mining calculator?

This calculator surfaces the break-even electricity rate explicitly and is built around comparing specific hardware classes against each other at the same rate, rather than treating 'mining profitability' as a single generic number that ignores which ASIC generation you're actually running.

- **Network difficulty** — A value that adjusts roughly every two weeks to keep Bitcoin's average block time near 10 minutes as total network hashrate changes.
- **Break-even electricity rate** — The maximum per-kWh electricity cost at which a given miner's revenue still covers its power cost, holding hashrate, difficulty, and price fixed.
