Subsidy eras

Era 0 paid 50 BTC; each 210,000 blocks halves the subsidy. Era 4 (post-2024) pays 3.125 BTC until the next cut. Fees are extra and not shown in the base subsidy.

Annual issuance sketch

Blocks average every 10 minutes. Annual BTC ≈ subsidy × blocks per year. Circulating supply approaches 21 million asymptotically.

Sources & methodology

Factual claims cite primary documentation. Interpretation and calculator assumptions are labeled separately so you can verify the source yourself.

  • Source: Bitcoin Developer Documentation — New bitcoins enter circulation as the block subsidy when a miner successfully mines a block; the subsidy halves every 210,000 blocks.

    GetFreeBit analysis: Era table on this page follows the standard halving schedule. Transaction fees are additional miner revenue and vary block to block.

Examples

  • Mark 3.125 BTC subsidy in USD at live spot.
  • Compare era-3 (6.25) vs era-4 (3.125) annual issuance.
