Bitcoin Halving Countdown
Track the next Bitcoin halving with live block data from the network. Analyze how past halvings impacted price, model post-halving scenarios for your portfolio, and explore what could happen if historical cycles repeat.
The next Bitcoin halving is expected around April 2028 at block 1,050,000, when the block reward drops from 3.125 BTC to 1.5625 BTC. This countdown reads the live block height from mempool.space every 60 seconds and estimates the date using a 10-minute average block time, so the ETA shifts as network speed changes.
Estimated: April 13, 2028

Bitcoin Supply Schedule (2009 – 2140)
Bitcoin's supply follows a predictable issuance schedule. The block reward halves every 210,000 blocks (~4 years), creating a disinflationary monetary policy. By 2140, all 21 million BTC will have been mined.

Historical Halving Performance
Bitcoin's price has historically trended upward following each halving event due to the resulting supply shock. Here is the breakdown for each cycle:
| Halving Date | Price at Halving | 1 Month After | 6 Months After | 1 Year After |
|---|---|---|---|---|
| 2012-11-28 | $12 | $13 | $123 | $964 |
| 2016-07-09 | $650 | $590 | $910 | $2,550 |
| 2020-05-11 | $8,800 | $9,400 | $15,500 | $56,000 |
| 2024-04-19 | $64,000 | $66,000 | $68,000 | ? |
Note: Past performance is not an indicator of future results. The supply shock usually reflects in the price with a 12-18 month lag.
How the Bitcoin Halving Countdown Works
Four steps to understanding Bitcoin's halving cycle and its potential impact
-
01
Track the Countdown
Our live countdown fetches the current block height from the Bitcoin network every 60 seconds, calculating the exact blocks remaining until halving #5 at block 1,050,000.
-
02
Study the Pattern
Review how Bitcoin's price performed after each of the 4 previous halvings with interactive charts and detailed performance tables.

04
Monitor Supply
Track Bitcoin's real-time supply metrics including total mined, remaining supply, current inflation rate, and the issuance schedule through 2140.
Understanding the Bitcoin Halving Cycle
The Bitcoin halving is the most predictable monetary event in financial history. Every 210,000 blocks — roughly every four years — the reward miners receive for adding a new block is cut in half. This single line of code, written by Satoshi Nakamoto in 2009, is what makes Bitcoin's supply schedule provably scarce: 21 million coins, no exceptions, no central bank, no surprises.
The next halving (#5) is projected for April 2028 at block height <strong>1,050,000</strong>, when the reward will drop from 3.125 BTC to 1.5625 BTC per block. By that point, more than 96% of all Bitcoin that will ever exist will already have been mined. Our countdown pulls live block-height data from the Bitcoin network every 60 seconds, so the date you see updates in real time as miners discover blocks faster or slower than the 10-minute target.

| Halving | Date | Price at Halving | Price 1Y After | Cycle ATH | Days to ATH |
|---|---|---|---|---|---|
| #1 | Nov 2012 | $12.35 | $1,000 (+8,000%) | $1,163 | 368 |
| #2 | Jul 2016 | $650 | $2,500 (+285%) | $19,783 | 525 |
| #3 | May 2020 | $8,821 | $56,700 (+543%) | $69,044 | 549 |
| #4 | Apr 2024 | $64,000 | $97,000 (+52%) | $109,000 | 290 |
| #5 | Apr 2028 (est.) | TBD | — | — | — |
Each cycle has produced smaller percentage gains but larger absolute dollar moves. The diminishing-returns pattern is what most analysts watch when modelling the 2028 cycle.
The Supply Emission Curve
| Era | Years | Reward / Block | BTC Created | % of 21M |
|---|---|---|---|---|
| Era 1 | 2009–2012 | 50 BTC | 10,500,000 | 50.0% |
| Era 2 | 2012–2016 | 25 BTC | 5,250,000 | 25.0% |
| Era 3 | 2016–2020 | 12.5 BTC | 2,625,000 | 12.5% |
| Era 4 | 2020–2024 | 6.25 BTC | 1,312,500 | 6.25% |
| Era 5 (now) | 2024–2028 | 3.125 BTC | 656,250 | 3.125% |
| Era 6 | 2028–2032 | 1.5625 BTC | 328,125 | 1.56% |
| Era 33+ | ~2140 | ≈ 0 BTC | Last sat | 100% |
By 2032, more than 98% of all Bitcoin will be in circulation. The remaining 2% will trickle out over the next 108 years, with the final satoshi mined around the year 2140. After that, miners earn revenue exclusively from transaction fees — a transition the network has been preparing for since day one.
Why the Halving Moves the Market
The mechanics are simple: Bitcoin's daily issuance drops by 50% overnight while demand stays flat or grows. In April 2024, daily new supply fell from roughly 900 BTC to 450 BTC. At the 2028 halving, it will fall to 225 BTC per day — less than what a single mid-sized ETF can absorb in an afternoon. That's the supply shock thesis in one sentence.
History has been kind to this thesis. After every previous halving, Bitcoin reached a new all-time high within 290 to 549 days. But the percentage gains have shrunk each cycle — 8,000% became 285%, then 543%, then 52% — as the asset matures and the marginal-buyer effect weakens. Most serious analysts now model the 2028 cycle in the 80–200% range rather than expecting another 10x rip.

A note on the countdown's accuracy
Bitcoin doesn't tick on a clock — it ticks on blocks. The protocol targets one block every 10 minutes, but actual block times fluctuate with hashrate. When mining capacity grows faster than the difficulty adjustment, blocks come in faster and the halving date drifts earlier. When hashrate drops (as it did briefly in mid-2021), blocks slow down and the date drifts later. Our countdown uses the live current block height, so the estimated date you see is always the most accurate available approximation.
