Bitcoin Halving Countdown — Blocks and Time to the Next Halving

What the halving is

Every block a miner adds pays a fixed subsidy of new bitcoins. Every 210,000 blocks — roughly four years — that subsidy is cut in half. The rule is written into the protocol and needs no vote: it is the entire issuance schedule of bitcoin, known in advance down to the last coin.

The last halving happened on 20 April 2024 at block 840,000, cutting the reward from 6.25 to 3.125 BTC. The next one waits at block 1,050,000, where the reward becomes 1.5625 BTC.

Why the countdown runs on blocks, not the calendar

The halving is tied to block height, not to a date. Which block triggers it is known exactly; when that block arrives depends on how fast the network finds blocks. Difficulty retargets every 2016 blocks to keep the average near ten minutes, but the actual pace drifts. So the number of blocks left on this page is exact, while the date is an estimate from the current average — a month out it moves by days.

What the numbers mean

• Block reward — how many new BTC are created every ~10 minutes right now, and what it becomes after the halving.
• BTC inflation per year — annual issuance against the coins already in existence. It halves at every halving: that is the whole point of the mechanism.
• BTC issued — how much of the 20,999,999.9769 cap already exists. Not exactly 21 million: halving the subsidy in satoshis never quite reaches the round number.
• Epoch progress — how much of the current four-year cycle has passed.

About the history and the price

The halving table shows the price on the day and after a month, six months and a year. Treat it as reference, not a pattern: there have been four halvings, and four observations cannot support a claim about the future. Prices come from our own daily-close database starting in November 2013, so the 2012 halving shows a dash — we do not substitute an estimate for data.
