# Margin tiers

Like most centralized exchanges, the tiered leverage formula on Hyperliquid is as follows:

`maintenance_margin = notional_position_value * maintenance_margin_rate - maintenance_deduction` 

On Hyperliquid, `maintenance_margin_rate` and `maintenance_deduction` depend only on the margin tiers, not the asset.

`maintenance_margin_rate(tier = n) = (Initial Margin Rate at Maximum leverage at tier n) / 2` . For example, at 20x max leverage, `maintenance_margin_rate = 2.5%`.

Maintenance deduction is defined at each tier to account for the different maintenance margin rates used at previous tiers:

`maintenance_deduction(tier = 0) = 0`   

`maintenance_deduction(tier = n) = maintenance_deduction(tier = n - 1) + notional_position_lower_bound(tier = n) * (maintenance_margin_rate(tier = n) - maintenance_margin_rate(tier = n - 1))` for `n > 0` 

In other words, maintenance deduction is defined so that new positions opened at each tier increase maintenance margin at `maintenance_margin_rate` , while having the total maintenance margin be a continuous function of position size.

Margin tables have unique IDs and the tiers can be found in the `meta` Info response. For IDs less than 50, there is a single tier with max leverage equal to the ID.
