Method
Telegram says the threshold depends on total subscribers but does not publish the formula in its FAQ. This is an estimate based on the figures you enter. Check the exact requirement in Telegram.
Coefficient: K = floor(subscribers ÷ 250) + 1
Levels 1–8: ceil(K × level ÷ 2)
Level 9: K × 7
Levels 10–100: K × level
Key points
No. It is an estimate. Verify the final number inside Telegram.
The level requirement is linked to total subscribers, so a larger channel needs more boosts.
Levels unlock additional stories, custom reactions and channel appearance options.
No. This version is for Telegram channels. Groups require a separate method.
