Bitcoin Halving Countdown
The next bitcoin halving is expected around March 2028, 79,798 blocks from now, when the block reward falls from 3.125 BTC to 1.5625 BTC.
Halving history
Bitcoin’s price on the day of each halving, and one year later.
Bitcoin price and halvings
Monthly prices since 2012 on a log scale, so each step of ten is the same height.
Supply schedule
Every halving slows the arrival of new coins toward the 21 million cap.
What is the bitcoin halving?
A supply rule written into Bitcoin from the start.
Every 210,000 blocks
At roughly ten minutes per block, that works out to about four years between halvings.
Half the new supply
reward = 50 ÷ 2^(halvings so far)Miners are paid in new bitcoin. Each halving cuts that payment in two, so new supply falls.
Toward 21 million
Rewards keep halving until they reach zero around 2140. After that, miners earn only transaction fees.
About this page
The bitcoin halving cuts the reward miners receive for each new block in half. It happens every 210,000 blocks, about every four years, and is written into Bitcoin's code. The next one comes at block 1,050,000, when the reward drops from 3.125 to 1.5625 BTC. This bitcoin halving countdown shows the days, hours and blocks left and how much of the cycle is done.
The date is an estimate: blocks left multiplied by the average block time since the last halving. Blocks arrive a little faster or slower than ten minutes, so the date shifts as the count runs down. Block height and the recent pace come from mempool.space. The history table lists the four past halvings, from 2012 to 2024, with the price on the day and a year later.
Each halving slows the flow of new coins toward the 21 million cap. New supply falls from about 450 BTC a day to about 225 BTC after the next halving, and rewards keep halving until they reach zero around 2140, when miners will earn only fees. Price moves after past halvings are history, not a forecast for the next one.
Questions
Short answers to what people ask most.
It is expected around March 2028, at block 1,050,000, with 79,798 blocks still to be mined.
A cut in half of the reward paid for mining a block. It happens every 210,000 blocks, about every four years, on a schedule written into Bitcoin's code.
1.5625 BTC per block, half the current 3.125 BTC paid to miners.
November 2012 (block 210,000), July 2016 (420,000), May 2020 (630,000) and April 2024 (840,000). Each one cut the block reward in half.
No. Halvings belong to bitcoin and coins built on its model, such as Litecoin and Bitcoin Cash. Many others, ether included, have no halving schedule.
Blocks left are multiplied by the average time per block since the previous halving. The block count and that average come from mempool.space and are checked every few minutes.
