Next bitcoin halving
Estimated date from the current block, a live countdown and what happens to mining when the block subsidy is cut in half.
The next bitcoin halving will happen around February 25, 2028 (between Feb 1, 2028 and Mar 19, 2028, depending on block times) at block 1,050,000: 74,208 blocks to go, and the reward will drop to 1.5625 BTC per block.

Price rising after past halvings does not guarantee it will happen again: these are four cases in very different contexts.

The halving has no fixed calendar date: it happens when the network mines block 1,050,000. This page estimates it from the current block height and the average block time since the last difficulty adjustment (mempool.space), and shows a range with blocks 5% faster or slower. It also calculates, at your electricity price, which machines in the catalog still make money once the subsidy is halved, and reviews the four previous halvings with on-chain data.
How the date is estimated
Current block
We read the network's block height right now.
Blocks to go
Up to the next multiple of 210,000: the next one is 1,050,000.
Block pace
Multiplied by the recent average block time, with a ±5% range.
What's included
Live countdown
From block height and the network's real pace, not a copied date.
Impact on your mining
Which ASICs still make money at your rate when the subsidy is halved.
History with data
All four halvings: date, block, reward, price and hashrate.
Sources in sight
On-chain and mempool.space data, with the check date.
Your rate
Rates by country (GlobalPetrolPrices) or the one you type.

Compared with other countdowns
Most countdowns only show a date; this one also tells you what it means for your mining.
- Date with a range, from the real block pace
- Which machines stay profitable afterwards, at your rate
- History with sources: on-chain data, not memory
- No exchange links and no price promises
Frequently asked questions
When is the next bitcoin halving?
It happens when block 1,050,000 is mined. At the block pace of November 2026 that falls around April or May 2028; at the top of this page you have the estimated date and countdown updated with the current block.
What is the bitcoin halving?
It is the cut in half of the reward miners receive for each block. It happens every 210,000 blocks (about four years) and is written into bitcoin's code: that is how issuance is capped at 21 million.
What will the block reward be after the next halving?
It will drop from 3.125 to 1.5625 BTC per block. Miners still collect transaction fees on top.
Why does the halving date keep changing?
Because it depends on blocks, not days. If blocks come faster than every 10 minutes (when hashrate rises before a difficulty adjustment), the halving comes earlier; if they come slower, later.
What happened to the price after previous halvings?
Twelve months after each halving the price was higher: from 12.48 to 1,079.90 USD (2012), 655 to 2,372 USD (2016), 9,317 to 49,503 USD (2020) and 63,849 to 85,067 USD (2024), per mempool.space prices. That is four cases and no guarantee it repeats.
Will my ASIC still be profitable after the halving?
It depends on its efficiency and your power price. The table on this page shows each model's profit today and with the subsidy halved, at your electricity rate.
