What does 1 TH/s mean? Hashrate explained for buyers
What a terahash actually is, how small 1 TH/s is next to the whole Bitcoin network, and how to turn any hashrate into expected bitcoin per day with one dated formula.

The short answer
1 TH/s (one terahash per second) is one trillion attempts per second at the puzzle that wins a Bitcoin block. On 11 October 2026 the network, judged by difficulty, ran at about 950 EH/s, so 1 TH/s was roughly one billionth of it and earned on average about 47 satoshis a day from the block subsidy, before pool or provider fees. That figure moves with difficulty and price.
What is a hash, and what does TH/s measure?
A hash is a fixed-length fingerprint of some data. Bitcoin miners hash a candidate block over and over, changing a small number each time, looking for a result below a target the network sets. Each try is one hash. There is no shortcut: finding a valid block is pure trial and error.
Hashrate is how many of those tries happen each second. 1 TH/s means one trillion (10¹²) hashes per second.
Hashrate measures work, not money. What that work is worth depends on how much work everyone else is doing, the reward per block and the Bitcoin price. The rest of this article walks through each one.
TH/s vs PH/s vs EH/s: the units side by side
Each step up is a thousand times bigger than the last.
| Unit | Hashes per second | In TH/s | Where you usually see it |
|---|---|---|---|
| TH/s (terahash) | 10¹² (one trillion) | 1 | Single machines and cloud mining plans. Bitmain's air-cooled Antminer S21 is rated at about 200 TH/s. |
| PH/s (petahash) | 10¹⁵ | 1,000 | Industry hashprice figures, quoted in US dollars per PH/s per day |
| EH/s (exahash) | 10¹⁸ | 1,000,000 | Large mining pools and the whole Bitcoin network |
| ZH/s (zettahash) | 10²¹ | 1,000,000,000 | Network milestones: worked out from difficulty, the network was above 1 ZH/s in October 2025 and about 0.95 ZH/s in October 2026 |
How big is 1 TH/s next to the whole Bitcoin network?
In October 2026 the network's hashrate, worked out from difficulty, was about 950 EH/s. That is 950,000,000 TH/s. So 1 TH/s was about one 950-millionth of the network, roughly 0.0000001%.
Mining alone at that size, 1 TH/s would find a block about once every 18,000 years on average at October 2026 difficulty. That is why small miners join a mining pool, which splits the blocks it finds according to the work each member contributed.
So the useful way to think about a hashrate is as a share of the network's daily output, averaged over time. That is exactly what the formula below calculates.
The formula for expected BTC per day
- 1
Work out your share of the network
Divide your hashrate by the network hashrate, in the same unit. For 1 TH/s in October 2026: 1 ÷ 950,000,000 ≈ 0.00000000105.
- 2
Multiply by blocks per day
Bitcoin targets one block every 10 minutes, which is 144 blocks a day on average. Real days run over or under: about 157 blocks were found in the 24 hours before our snapshot. A count above 144 usually means hashrate has risen since the last difficulty reset, though luck plays a part.
- 3
Multiply by the block subsidy
Since the April 2024 halving at block 840,000, each block creates 3.125 new BTC. That makes 144 × 3.125 = 450 BTC a day for the whole network.
- 4
Put it together
Expected BTC per day = (your hashrate ÷ network hashrate) × 144 × 3.125. Multiply by 100,000,000 to get satoshis. This leaves out transaction fees, which add to what miners earn, and pool or provider fees, which reduce it. Luck makes any single day differ from the average.
- 5
Use difficulty for the network figure
Live hashrate charts are estimates and differ from site to site. The steadier number is the one implied by difficulty: difficulty × 2³² ÷ 600 gives hashes per second. Used in the formula, it matches the 144-blocks-a-day assumption exactly.
Worked example: 1 TH/s on 11 October 2026
Real network figures, taken at one moment. Use it to check your own maths, not as a forecast.
| Step | Value on 11 Oct 2026 | How it is found |
|---|---|---|
| Difficulty | 132,716,002,350,731 (about 132.72 T) | Block explorer, block 970,911 |
| Network hashrate | About 950 EH/s (950,000,000 TH/s) | Difficulty × 2³² ÷ 600 |
| Share for 1 TH/s | About 1 in 950 million | 1 ÷ 950,000,000 |
| Network issuance | 450 BTC a day | 144 blocks × 3.125 BTC |
| Expected BTC for 1 TH/s | About 0.00000047 BTC (47 satoshis) a day | Share × 450 BTC |
| BTC price | About $82,900 | Spot price around 10:30 UTC |
| Dollar value | About $0.039 a day, just under 4 cents | 47.4 satoshis × price |
Snapshot taken 11 October 2026, around 10:30 UTC. Difficulty resets about every two weeks and the price changes by the minute. This is gross network maths for 1 TH/s, before transaction-fee income, pool fees and provider fees. It is not what a Minevana plan pays.
Why the result keeps shrinking: difficulty and halvings
Every 2,016 blocks, about two weeks, the network resets difficulty so blocks keep arriving about every 10 minutes. When more hashrate joins, difficulty rises and the same 1 TH/s becomes a smaller share. Every 210,000 blocks the subsidy halves. Here is the same 1 TH/s through the same formula on different dates.
| Date | Difficulty | Block subsidy | Expected satoshis a day for 1 TH/s |
|---|---|---|---|
| April 2024, just before the halving | 86.39 T | 6.25 BTC | About 146 |
| April 2024, just after the halving | 86.39 T | 3.125 BTC | About 73 |
| October 2024 | 92.05 T | 3.125 BTC | About 68 |
| October 2025 | 150.84 T | 3.125 BTC | About 42 |
| Late October 2025 (record) | 155.97 T | 3.125 BTC | About 40 |
| 11 October 2026 | 132.72 T | 3.125 BTC | About 47 |
Difficulty from blockchain.com daily chart data; satoshis calculated with the formula above, excluding fees. Difficulty is not one-way: it fell about 15% from its late-2025 record to October 2026, so the figure rose. Over the long run it has mostly climbed as more machines are switched on, and the next halving, expected around 2028 at block 1,050,000, will cut the subsidy in half again.
Why the dollar figure moves with the Bitcoin price
The formula gives bitcoin, not dollars. The dollar figure is simply BTC × price, so it rises and falls with the market even when difficulty stays put.
Take the 47 satoshis from the worked example. At $60,000 a bitcoin they are worth about 2.8 cents, at $82,900 about 3.9 cents, and at $100,000 about 4.7 cents. Those prices are illustrations, not forecasts.
Price and difficulty also pull on each other. A higher price makes mining more rewarding, more machines get switched on, and difficulty can climb in the weeks after, taking back part of the gain. For everything else that drives the result, including electricity and hardware efficiency, see is cloud mining profitable in 2026.
How to use the mining calculator with today's numbers
- 1
Enter a hashrate
Open the mining calculator and type the TH/s you want to test into Your hashrate (TH/s). Start with 1 to check it against the worked example above.
- 2
Set the network hashrate
Put the current figure in EH/s into Network hashrate. To work it out yourself, take the difficulty from a block explorer, multiply by 4,294,967,296 (2³²), divide by 600, then divide by 10¹⁸. On 11 October 2026 that gave about 950.
- 3
Replace the default BTC price
The price field starts at $100,000. Change it to today's price, then try a lower one to see how much the result depends on the market.
- 4
Decide what to do with costs
Power + maintenance is what you would pay per TH/s per day. Set it to 0 to see gross network maths. If a provider has not published its fee, as Minevana has not, a gross figure cannot tell you what you would receive. Leave the efficiency slider at 0 for a plain estimate; it is an assumption you supply.
- 5
Stress-test the result
Raise the network hashrate by 10% or 20% to see what a few difficulty increases would do. The output also leaves out transaction fees and luck, so read it as a rough range, not a forecast.
