How much bitcoin does 1 TH mine per day?

It is the unit the whole industry sells in — miners are advertised per TH, billed per TH and compared per TH — and almost nobody knows what one actually produces. The articles that answer it usually quote a figure from two years ago without saying when it is from, and mining is exactly the place where that does not work: the number falls on its own every month.

So here it is with a date, with the maths in plain sight, and at the end checked against real payouts.

The answer

As of today, 1 TH mines around 50 satoshis a day: roughly $0.032 gross, before paying for anything. This table was just calculated with the state of the network at the moment you are reading:

The "reward the network issues" is what Bitcoin shares out across all the hashrate that is mining. What a miner actually receives is somewhat less, because in between there is pool commission and platform overhead: that 4.8% haircut is measured, not assumed, and it gets checked below.

Where that number comes from

No company sets it. The Bitcoin network sets it, and it is a division:

The 144 is how many blocks Bitcoin produces per day, one every ten minutes by design. Each block pays 3.125 BTC of subsidy today plus the fees of whatever transactions it carries. All of that is shared across all the hashrate on the planet, and your TH is a tiny sliver of it.

With the numbers from 27 July 2026: the network stood at 867 EH/s, that is 867 million TH. Each block paid 314,516,210 sats between subsidy and fees. The whole sum:

That is the reward the network issues. What reaches the miner is around 49.7, and the difference is explained in full — with its measurement and its limits — on the methodology page.

The check: the model against real payouts

So far this is theory. The honest question is whether that number resembles what actually gets paid.

These are the real payouts of two 1 TH miners observed in the GoMining app between 15 and 27 July 2026, one at 12 W/TH and one at 15 W/TH, with a 14% maintenance discount applied. Beside them, what this site's model predicts for that same day:

Net for 27 July 2026, with bitcoin at $64,943 and a 14% discount. Across the full 13 days, the average deviation of the daily net is $0.0003 — which is exactly the size of the dashboard's own rounding, since it shows the reward in whole satoshis (49 or 50, ±1%).

And the most useful part of that check is what it says about the reward: the observed payouts average 49.54 sat/TH/day against the network's 52.24 theoretical. That is a factor of 0.948, against the 0.952 this calculator uses. A 0.4% difference on the parameter we ourselves flag as the least reliable in the model.

Put another way: the two cost formulas match within 0.6% and the reward within 0.4%. It is not that the model is elegant — it is that it produces what people are paid.

What it costs to keep that TH running

This is where the number stops being trivia. A TH does not only produce: it also burns electricity and pays a service fee. And those costs take nearly all of it:

A single TH, electricity at $0.05/kWh and no maintenance discounts at all, to see the bare case. The service fee is $0.0089 per TH per day, identical for everyone; the only thing changing between rows is the power bill.

Look at the right-hand column and keep hold of this: one efficient terahash makes about three dollars a year. Three. A year.

That is the fact that organises everything else in this business, and the one that explains why things are the way they are:

• Why people buy thousands of TH. At three dollars a year per unit, for this to mean anything you need hundreds or thousands. It is not greed: below a certain scale the result is loose change.
• Why efficiency decides. Income is identical across all four rows. The only thing that changes is the power bill, so efficiency is not an extra: it is literally half the equation.
• Why 5% on the reward matters so much. When the margin lives in the fourth decimal place, a 5% difference in income eats an enormous share of what is left. That is why the pool factor is not a technical detail.
• And why an inefficient miner loses money. Nothing strange has to happen. The power bill just has to exceed three cents, and at 28 W/TH it does, every single day.

Two miners, the same bitcoin, 34% apart

The two miners in the receipt above are almost a laboratory experiment: both have 1 TH, both mined exactly the same bitcoin on the same day, both paid the same service fee and both had the same discount. The only difference was efficiency.

34% more profit from mining exactly the same bitcoin. All of that difference comes from one thing: three watts less per terahash.

If you ever wonder why this site keeps banging on about W/TH rather than TH, those two rows are the answer.

And this number falls on its own

What makes mining hard to calculate is not the formula, it is that the result moves under your feet. Three things are pushing, and only one of them can go your way.

Difficulty rises. More machines arrive every month and the same reward is split across more TH, so your slice shrinks. This is not theoretical: while this article was being written, the network hashrate went from 915 to 867 EH/s in three days, and that alone moved the reward per TH by almost 6% — upwards in that instance, because competition fell. Over the long run it moves the other way, historically between 1% and 3% a month against you.

The halving arrives. Around April 2028, at block 1,050,000, the subsidy drops from 3.125 to 1.5625 BTC. Half. Everything else being equal, this number halves overnight.

And the bitcoin price does whatever it wants. The sats you mine do not change with the price; what changes is what they are worth. Since electricity and the service fee are paid in dollars and do not negotiate, the BTC price is what decides whether those 50 sats cover the costs.

The projections in the calculator apply the first two and let you pick a scenario for the third. That is why they come out lower than other tools': the others usually assume the network stands still.

So how many TH do you need?

That is the question all of this leads to. With the numbers from 27 July 2026, an efficient 12 W/TH miner with no discounts needs on the order of 200 TH for $50 net a month and about 400 TH for $100. With discounts active it drops considerably, and with worse efficiency it climbs fast until it never gets there.

Those two figures move a lot, and fast: they depend on the bitcoin price and on difficulty, which is exactly what the table further up recalculates on its own. Take them as an order of magnitude, not as a constant.

If you want the exact number for your case — your TH, your efficiency, your discounts — the calculator does it with live network data, and how much you need to invest for $1,000 a month has the capital maths for bigger targets.

In short

• 1 TH mines around 50 satoshis a day, roughly $0.032 gross. Verified 27 July 2026; come back later and it will be a different number, and the table above will have recalculated it.
• It comes from a division: what the network issues, divided by all the hashrate mining. No company sets it.
• That number is checked against real payouts: costs within 0.6% and reward within 0.4%.
• After costs, about three dollars a year per TH with an efficient machine. That is the explanation for why people buy thousands.
• Efficiency is half the equation. Two miners with the same TH and the same bitcoin mined kept amounts 34% apart.
• And the number falls on its own, through difficulty and the halving. Any calculation that does not apply both is showing you a better result than you are going to get.
