The Equation (No Jargon)

Think in blocks. The reward starts at 50 BTC per block, then halves to 25, 12.5, 6.25, and so on every 210,000 blocks.

Block reward by era (k):\n\nReward(k) = 50 × (1/2)^{k}\n\n• k = 0 → 50 BTC (genesis era)\n• k = 1 → 25 BTC\n• k = 2 → 12.5 BTC\n• k = 3 → 6.25 BTC\n• k = 4 → 3.125 BTC … and so on

Which era am I in?\n\nk = floor(blockHeight / 210,000)\n\nEvery 210k blocks we move to the next era and the reward halves.
