By the emission schedule at the current block.The fifth Bitcoin halving will happen at block 1,050,000. The block reward will drop from 3.125 to 1.5625 BTC. The block number is fixed by the protocol. The date can only be estimated: at the current network pace it falls in 2028, and the countdown at the top of the page shows the estimated day.
Bitcoin finds 144 blocks a day on average, about one every 10 minutes. The countdown takes the actual average block time over the last 24 difficulty epochs, about 11 months, and multiplies it by the blocks left. Bitcoin difficulty is recalculated every 2,016 blocks, about two weeks. A single epoch can run noticeably faster or slower than ten minutes, but the next recalculation brings the pace back to target. On the network's history, a one-epoch average missed the pace of the following year and a half by 3.7% on average, a 24-epoch average by less than 1%. So the date does not jump by weeks after every recalculation.
Dates of past halvings are the UTC time of the block. Future dates are estimates.
| Event | Date | Block | Block reward |
|---|---|---|---|
| Network launch | 2009-01-03 | 0 | 50 BTC |
| 1st halving | 2012-11-28 | 210,000 | 50 → 25 BTC |
| 2nd halving | 2016-07-09 | 420,000 | 25 → 12.5 BTC |
| 3rd halving | 2020-05-11 | 630,000 | 12.5 → 6.25 BTC |
| 4th halving | 2024-04-20 | 840,000 | 6.25 → 3.125 BTC |
| 5th halving | expected 2028 | 1,050,000 | 3.125 → 1.5625 BTC |
| 6th halving | expected 2032 | 1,260,000 | 1.5625 → 0.78125 BTC |
There will be just under 21 million bitcoins. Each halving cuts issuance for the next four years in half, so most coins are already mined. The amount issued by the emission schedule as of the current block is shown above.
The reward is counted in satoshis, and fractions of a satoshi are dropped. After the 33rd halving, at block 6,930,000, the reward becomes zero. At today's pace that is around 2140. From then on miners will earn transaction fees only.
From block 1,050,000 an ASIC's income in bitcoin for the same hashrate drops by almost half. Not exactly half, because transaction fees stay the same and their share of the reward grows after the halving. On a pool with FPPS payouts the accrual rate follows the new reward by itself, the same day.
The least energy-efficient machines, in joules per terahash, become unprofitable first. Nobody knows in advance how the price and difficulty will move after the halving, so recheck payback in the profitability calculator with a 1.5625 BTC reward and your own electricity price.
At block 1,050,000, expected in 2028. The countdown at the top of the page shows the estimated date and the blocks left; it updates from the RuPool pool's nodes.
The exact day is not known in advance: a halving is tied to a block number, not the calendar. The closer the halving, the more precise the estimate: a couple of weeks before the event the error shrinks to a few hours.
Subtract the current block height from 1,050,000. The countdown does it automatically and converts blocks to days using the actual average block time.
1.5625 BTC instead of 3.125 BTC. Transaction fees are added on top, as before.
