Daily block counts derived from blockchain.com's per-block supply series, bucketed to UTC days; live block height and block times from mempool.space. Issuance is computed from those observed heights using Bitcoin's own consensus rules — a 50 BTC subsidy halving every 210,000 blocks, capped at 21,000,000 BTC — so a period spanning a halving is split at the exact block.

Supply figures follow the protocol's issuance formula. They include coins that are provably lost or were never claimed by miners, so the amount actually spendable is lower. The current period is still in progress and its bar is not yet complete.

Every calculator here runs on formulas verified against primary sources and is reviewed before it ships.

How to read the issuance chart

  • Issuance dropdown — switches the chart between Daily, Weekly, Monthly, Quarterly, and Yearly views.
  • Range control — sets how far back the chart looks, with choices tailored to the selected scale.
  • Hollow bar — marks the period still in progress, whose total isn’t final yet.
  • Dashed marker — flags a bar whose period spans a halving, when the block subsidy changed partway through.
  • Headline line — reports the last complete period’s actual issuance against what the 10-minute block target implies.

Why actual Bitcoin issuance differs from the schedule

The 10-minute block target implies a fixed issuance rate at the current subsidy: 3.125 BTC per block, or 450 BTC across a 144-block day.

Real block times drift with the network’s hash rate, so any real period rarely mines exactly 144 blocks a day.

Faster blocks push a period’s block count above the 144-block pace, so its actual issuance runs ahead of the scheduled figure. Slower blocks push the count below it, so issuance falls short.

The headline line above the chart reports the gap between actual and scheduled issuance for whichever period last closed.

Difficulty retargets every 2,016 blocks to pull block pace back toward 10 minutes, but it works forward only — it never changes what an already-closed period issued.

How Bitcoin issuance is calculated

Every bar’s issuance figure comes from the same block-height method: cumulative supply at the period’s ending block height, minus cumulative supply at its starting height.

Cumulative supply itself sums the block subsidy across every block mined since genesis, with the subsidy cut in half every 210,000 blocks under Bitcoin’s halving schedule.

A period whose date range crosses a halving is split at the exact block where the subsidy changes, rather than blended across the transition. Blocks before that height count at the old subsidy, and blocks after it count at the new one, so the bar reflects exactly what the network paid out.

Bitcoin’s supply growth rate compared to gold

The stats panel’s supply growth per year figure states Bitcoin’s issuance as a percentage of existing supply — the lens analysts use to compare monetary hardness.

Gold’s above-ground stock grows by around 1.6% a year from new mine production. The World Gold Council puts total gold ever mined near 222,600 tonnes, against annual output of roughly 3,600 tonnes.

Bitcoin’s issuance rate is cut in half at every halving, so it already sits below gold’s and keeps shrinking toward zero as future halvings compound.

Frequently asked questions

  • How many bitcoins are there right now?
    The bitcoin in existence right now is the total shown in the stats panel above, recalculated automatically as each new block confirms. It comes from Bitcoin's halving schedule applied to the live block height. The subsidy started at 50 BTC per block, halves every 210,000 blocks, and has stepped down 4 times since the 2009 genesis block. Summing that schedule up to the current height gives the exact figure the panel displays.
  • How many bitcoins are left to mine?
    Bitcoins left to mine is the 21,000,000 BTC supply cap minus the amount already issued, shown live in the stats panel above. At the current subsidy, that gap closes by roughly 450 BTC a day. The pace halves at every future halving, so the remaining supply shrinks more slowly with each cycle until issuance rounds down to zero around 2140.
  • What is the Bitcoin block subsidy?
    The Bitcoin block subsidy is the newly created bitcoin paid to a miner for producing a valid block, separate from any transaction fees the block includes. It started at 50 BTC in 2009 and halves every 210,000 blocks, standing at 3.125 BTC per block since the 2024 halving. The subsidy is the entire source of new bitcoin issuance, and the chart above sums it block by block to produce each period's total.
  • Why does actual Bitcoin issuance differ from the scheduled rate?
    Actual Bitcoin issuance differs from the scheduled rate because the 10-minute block target is an average, not a guarantee. Block pace depends on the network's hash rate, so a period with faster-than-average blocks mines more BTC than the schedule implies, and a period with slower blocks mines less. The difficulty adjustment, recalculated every 2,016 blocks, pulls block pace back toward 10 minutes, though it acts on the blocks ahead rather than on the period the chart has already reported.
  • When will the last bitcoin be mined?
    The last bitcoin is projected to be mined around the year 2140, once enough halvings have driven the block subsidy down to zero under Bitcoin's integer-based accounting. Supply approaches the 21,000,000 BTC cap asymptotically rather than hitting it on a fixed date, since each halving keeps issuing a smaller but positive amount for over a century. The exact date is an estimate: it depends on the network's average block interval holding close to 10 minutes across dozens of future halvings.
  • Is Bitcoin's supply growth rate similar to gold's?
    Bitcoin's supply growth rate is not similar to gold's over the long run, even though the two sit close today. Gold's above-ground stock grows by around 1.6% a year from new mine production, according to World Gold Council data. Bitcoin's issuance rate, shown live in the stats panel above, already sits below that. It keeps halving on a fixed schedule, though, so it diverges further from gold's steady pace with every future halving.
